As shown in this figure, the server system 1 includes a management server device 100 and a plurality of server facilities 200 (200-1, 200-2, 200-3,...). In the present embodiment, the server facilities 200-1, 200-2, 200-3,... Have the same configuration and indicate any server facility provided in the server system 1, or when they are not particularly distinguished. The server facility 200 will be described below.

The management server device 100 and the plurality of server facilities 200 are connected via a network NW and can communicate with each other.
The plurality of server facilities 200 are distributed in different places. The plurality of server facilities 200 are assumed to be arranged in various places around the world (for example, places with different longitudes) so that the periods in which power generation is possible are different depending on, for example, sunlight from the sun. That is, it is assumed that each of the plurality of server facilities 200 is arranged at a place where the peak position of the power generation amount that changes corresponding to the diurnal motion of the sun is different. Here, the power generation amount is the power generation amount of the power generation device 21 described later.

  The server facility 200 includes a power generation device 21, a PCS (power conditioner) 22, a switch unit 24, a control device 25, and a plurality of server devices 300 (300-1, 300-2,...). In the present embodiment, the server device 300-1, the server device 300-2,...

In addition, this embodiment demonstrates an example in case the electric power generating apparatus 21 is a solar power generation device which has a solar cell which generate | occur | produces with sunlight. The power generation device 21 generates direct-current power with sunlight, and outputs the generated direct-current power to the PCS 22. The power generation device 21 supplies the generated power to the server device 300 via the PCS 22. Since the power generation device 21 is a solar power generation device, the amount of power generation periodically changes corresponding to the diurnal motion of the sun.

  The PCS 22 performs control so that the power generated by the power generation device 21 is maximized by, for example, MTTP (Maximum Power Point Tracking) control, and converts the output power from the power generation device 21 into AC power having a predetermined output voltage. To the supply line L1. Further, the PCS 22 measures a power generation amount that is power generated by the power generation device 21 by a sensor unit (not shown) in response to an instruction from the control device 25, and outputs the measured power generation amount to the control device 25. Further, the PCS 22 switches whether to output power to the supply line L1 in accordance with an instruction from the control device 25.

  The switch unit 24 is a switch connected between a supply line L2 from the commercial power supply 23 (commercial power system) and a supply line L1 that supplies power to the server device 300. In response to an instruction from the control device 25, the switch unit 24 is turned on (closed) when receiving power from the commercial power source 23, and is turned off when not receiving power from the commercial power source 23 ( Open state).

  The control device 25 controls the entire server facility 200 in an integrated manner. For example, the control device 25 controls the switch unit 24 and the PCS 22 in order to supply power to the supply line L1. In addition, the control device 25 acquires, for example, the power generation amount of the power generation device 21 from the PCS 22 at predetermined time intervals, and sends the acquired power generation amount of the power generation device 21 to the management server device 100 according to an instruction from the management server device 100. And output via the network NW.

The server apparatus 300 is a computer apparatus that provides predetermined services such as provision of files (data), provision of information via the web, provision of applications, provision of resources for calculation processing, and the like.

The storage unit 110 stores various information used in the processing of the management server device 100. The storage unit 110 includes, for example, a management information storage unit 111 and a power supply information storage unit 112.
The management information storage unit 111 stores information for managing the server facility 200 and the server device 300. For example, as illustrated in FIG. 2, the management information storage unit 111 associates “server equipment ID”, “location information (latitude, longitude)”, “facility operating state”, and “server apparatus ID”. Remember.

FIG. 2 is a diagram illustrating a storage example of the management information storage unit 111 in the present embodiment.
In this figure, “server facility ID” indicates identification information for identifying the server facility 200 included in the server system 1, and “position information (latitude, longitude)” indicates position information where the server facility 200 is located, It is indicated by latitude and longitude. The “facility operating state” indicates whether or not the server device 300 included in the server facility 200 is operating, and the “server device ID” is identification information for identifying the server device 300 included in the server facility 200. The “server facility ID”, “position information (latitude, longitude)”, and “server device ID” are predetermined information.

  In the example illustrated in FIG. 2, the server facility 200 whose “server facility ID” is “S001” has a location where “position information (latitude, longitude)” is “latitude: 35.69 degrees, longitude: 139.69 degrees”. It is shown that it is arranged. Further, the server facility 200 of “S001” includes the server device 300 of “SV001”, “SV002”,... With “server device ID” being “operating”. Therefore, it is indicated that these server apparatuses 300 are in operation. On the other hand, since the “facility operating state” of the server equipment 200 “S002” is “stopped”, the server devices 300 of “SV201”, “SV202”,. Is shown.

  Returning to FIG. 1, the power supply information storage unit 112 stores information related to power supply (power supply) in the server facility 200. For example, as illustrated in FIG. 3, the power supply information storage unit 112 includes a “server facility ID”, a “maximum power generation amount (W (watt))”, a “current power generation amount (W)”, and a “equipment power consumption”. (W) ”is stored in association with each other.

FIG. 3 is a diagram illustrating a storage example of the power supply information storage unit 112 in the present embodiment.
In this figure, “maximum power generation amount (W)” indicates the maximum power generation amount of the power generation device 21 included in the server facility 200, and “current power generation amount (W)” indicates the current power generation amount of the power generation device 21 included in the server facility 200.

The selection unit 131 selects the server facility 200 from among the plurality of server facilities 200 based on the power generation amount of the power generation device 21 so that the server device 300 provides a predetermined service. For example, the selection unit 131 selects the server equipment 200 from among the plurality of server equipments 200 in descending order of the power generation amount of the power generation device 21 so as to provide a predetermined service. That is, the selection unit 131 selects the current power generation amount of the power generation device 21 stored in the power supply information storage unit 112 from the plurality of server facilities 200 stored in the power supply information storage unit 112 (“current power generation amount ( W) ”)), the server facility 200 that operates the server device 300 is selected in descending order of the power generation amount of the power generation device 21.
Further, the selection unit 131 operates the server apparatus 300 based on the power generation amount of the power generation apparatus 21 when the server facility 200 in which the server apparatus 300 is already operating exists and provides a predetermined service. The server equipment 200 to be selected is selected for changing. That is, for example, the selection unit 131 has a larger amount of power generation than the power generation amount of the power generation device 21 included in the server facility 200 in which the server apparatus 300 is already operating from among the server facilities 200 in which the server apparatus 300 is operating. The server facility 200 is selected as the server facility 200 that newly operates the server device 300. In this case, the selection unit 131 also selects a server facility 200 that newly stops the server facility 200 that is not selected as the server facility 200 that operates the server device 300 among the server facilities 200 that are already in operation. Here, the selected “server facility 200 that operates the server device 300” is referred to as “operation-selected server facility 200” in the following description. In addition, the server facility 200 selected as the “newly stopped server facility 200” is referred to as “stop selected server facility 200” in the following description.

  The selection unit 131 acquires the power generation amount of the power generation device 21 from the control device 25 of each server facility 200 via the communication unit 120 and the network NW at a predetermined time interval (for example, every few minutes). The power generation amount is stored as “current power generation amount (W)” in the power supply information storage unit 112 in association with the “server facility ID”. Moreover, the selection part 131 may perform the process which selects the server equipment 200 mentioned above regularly, after acquiring the electric power generation amount of the electric power generating apparatus 21. FIG.

  The power supply control unit 133 supplies the power generated by the power generation device 21 included in the server facility 200 selected for operation by the selection unit 131 to the server device 300 included in the server facility 200 selected for operation by the selection unit 131.

That is, the power supply control unit 133 instructs the control device 25 of the server equipment 200 that has been selected to operate to supply power from the power generation device 21 to the server device 300 via the communication unit 120 and the network NW ( Command). The control device 25 outputs an instruction (command) to supply power to the supply line L1 to the PCS 22.

  The management control unit 132 operates the server device 300 included in the server facility 200 selected for operation by the selection unit 131, and causes the server device 300 to provide a predetermined service via the network. That is, the management control unit 132 activates the server device 300 of the server facility 200 selected for operation via the communication unit 120 and the network NW, and executes a program that provides a predetermined service. When installation of application programs and data (files) is necessary to provide a predetermined service, the management control unit 132 is necessary for the server device 300 via the communication unit 120 and the network NW. Various application programs and data (files) are installed. When the server apparatus 300 of the server facility 200 is operated, the management control unit 132 sends information indicating that the server facility 200 is in operation (for example, “in operation”) to the server facility 200 selected for operation. The information is stored in the “facility operating state” of the management information storage unit 111 associated with the corresponding “server facility ID”.

Further, when the server facility 200 in which the server device 300 is already operating exists and provides a predetermined service, the management control unit 132, for example, from the server device 300 of the server facility 200 selected to be stopped, Switch to the server device of the server facility 200 selected for operation. That is, the management control unit 132 has already operated the server apparatus 200 having the server apparatus 200 having the large power generation amount selected by the selection unit 131 and having the power generation amount smaller than that of the server facility 200 selected to be operated. The server apparatus 300 is operated instead of the server apparatus 300 that is operating.
When the server apparatus 300 of the server facility 200 is stopped, the management control unit 132 uses information indicating that the server facility 200 is stopped (for example, “stopped”) as the server facility selected to stop. 200 is stored in the “facility operating state” of the management information storage unit 111 associated with the “server facility ID” corresponding to 200.

FIG. 4 is a block diagram illustrating an example of the server apparatus 300 in the present embodiment.
As shown in this figure, the server device 300 includes a communication unit 31, a CPU 32, a RAM 33, a ROM 34, and an HDD 35.
The communication unit 31 performs communication via the network NW. The communication unit 120 communicates with, for example, the management server device 100, the control device 25, and the client device described above.

  In the present embodiment, the communication unit 31, the CPU 32, the RAM 33, the ROM 34, and the HDD 35 correspond to the physical machine 30 that is a computer device. The physical machine 30 provides a predetermined service by executing a preprogram using the communication unit 31, the CPU 32, the RAM 33, the ROM 34, the HDD 35, and the like as computer resources.

Next, the operation of the server system 1 in this embodiment will be described with reference to the drawings.
FIG. 5 is a flowchart showing an example of the operation of the server system 1 according to the present embodiment.
Here, an example will be described in which the computer resources of each server device 300 are the same, and the maximum power generation amount of each server facility 200 and the number of server devices 300 are the same.

  In this figure, first, the management server device 100 acquires the power generation amount of each server facility 200 (step S101). That is, the selection unit 131 of the control unit 130 acquires the power generation amount of the power generation device 21 from the control device 25 of each server facility 200 via the communication unit 120 and the network NW, and the acquired power generation amount is “current power generation amount ( W) ”is stored in the power supply information storage unit 112 in association with the“ server equipment ID ”.

  Next, the selection part 131 selects the server equipment 200 which operates based on the acquired electric power generation amount (step S102). Specifically, the selection unit 131 selects the server equipment 200 from among the plurality of server equipments 200 in descending order of the power generation amount of the power generation device 21 so as to provide a predetermined service. That is, the selection unit 131 generates the power generation device based on the current power generation amount (“current power generation amount (W)”) of the power generation device 21 stored in the power supply information storage unit 112 from among the plurality of server facilities 200. The server facility 200 that operates the server device 300 is selected in descending order of the power generation amount 21.

  Next, the power supply control unit 133 of the control unit 130 supplies power from the power generation device 21 to the server device 300 of the server facility 200 selected for operation (step S103). That is, the power supply control unit 133 instructs the control device 25 of the server equipment 200 that has been selected to operate to supply power from the power generation device 21 to the server device 300 via the communication unit 120 and the network NW ( Command). As a result, the control device 25 outputs an instruction (command) to supply power to the supply line L1 to the PCS 22, and the PCS 22 supplies the output power of the power generation device 21 to each server device 300 via the supply line L1. To do.

  Next, the management control unit 132 of the control unit 130 operates the server device 300 of the server facility 200 selected for operation (step S104). That is, the management control unit 132 activates each server device 300 included in the server facility 200 selected for operation via the network NW, and executes a program for providing a predetermined service, for example, Provide services to users. In addition, the management control unit 132 associates information indicating that the server facility 200 is in operation (for example, “in operation”) with the “server facility ID” and sets the “equipment operating state” in the management information storage unit 111. Remember.

  Next, the selection part 131 acquires the electric power generation amount of each server equipment 200 again (step S105). The selection unit 131 acquires the power generation amount of the power generation device 21 from the control device 25 of each server facility 200 via the communication unit 120 and the network NW, similarly to the process of step S101 described above.

  Next, the selection unit 131 determines whether or not it is necessary to change the operating server equipment 200 (step S106). Specifically, the selection unit 131 determines whether, for example, there is a server facility 200 in which the server apparatus 300 is already operating that has a smaller amount of power generation than the server facility 200 in which the server apparatus 300 is not operating. Determine. The selection unit 131 selects the server facility 200 to be operated when there is a server power generation amount that is smaller than that of the server facility 200 in which the server device 300 is not operating among the server facilities 200 in which the server device 300 is already operating. Determine that a change is required. If the selection unit 131 determines that it is necessary to change the operating server equipment 200 (step S106: YES), the selection unit 131 advances the process to step S107. In addition, when the selection unit 131 determines that it is not necessary to change the operating server equipment 200 (step S106: NO), the selection server 131 returns the process to step S105, and the management server apparatus 100 performs the above-described process at a predetermined time interval. Repeatedly.

  In step S107, the selection unit 131 selects a server facility 200 that is to be newly operated. That is, the selection unit 131 selects the server facility 200 that newly operates the server device 300 and the server facility 200 that stops the server device 300 instead based on the power generation amount of the power generation device 21.

  Next, the power supply control unit 133 supplies power from the power generation device 21 to the server device 300 of the server facility 200 selected for operation (step S108). That is, the power supply control unit 133 instructs the control device 25 of the server equipment 200 that has been selected to operate to supply power from the power generation device 21 to the server device 300 via the communication unit 120 and the network NW ( Command).

  Next, the management control unit 132 operates the server device 300 of the server facility 200 selected for operation (step S109). That is, the management control unit 132 activates each server device 300 included in the server facility 200 selected for operation via the network NW.

  Next, the management control part 132 moves the server information of the server equipment 200 to stop (step S110). In other words, the management control unit 132 newly operates information stored in the server device 300 (such as the HDD 35) of the server facility 200 selected to be stopped (for example, a program and data related to the service to be provided). 200 server apparatuses 300 are moved via the network NW. Then, for example, the management control unit 132 executes a program for providing a predetermined service, and provides the user with the predetermined service. In addition, the management control unit 132 associates information indicating that the server facility 200 is in operation (for example, “in operation”) with the “server facility ID” and sets the “equipment operating state” in the management information storage unit 111. Remember.

  Next, the management control unit 132 stops the server device 300 of the server facility 200 selected to be stopped (step S111). That is, the service provision from the server device 300 of the server facility 200 selected to be stopped is stopped and the server device 300 is stopped.

Is the daytime, and the half of the earth EH including the position P1 and the position P2 is nighttime. In this case, the power generation amount of the server facility 200-3 and the server facility 200-4 is larger than the power generation amount of the server facility 200-1 and the server facility 200-2. The server facility 200-3 and the server facility 200-4 are selected. That is, when the state shown in FIG. 6B is changed to the state shown in FIG. 6C, the selection unit 131 selects the server equipment 200-4 as the server equipment 200 to be newly selected and stopped. The server facility 200-2 is selected as the server facility 200 to be selected.

  In this case, the management control unit 132 operates the server device 300 of the server facility 200-3 and the server facility 200-4 and stops the server device 300 of the server facility 200-1 and the server facility 200-2. Specifically, when the state shown in FIG. 6B is changed to the state shown in FIG. 6C, the management control unit 132 provides the service provided by the server device 300 of the server equipment 200-2 to the server equipment. The server apparatus 300 is changed (moved) so as to be provided.

  Next, in the example illustrated in FIG. 6D, at time T4, the half surface of the earth EH including the position P4 and the position P1 is irradiated with sunlight from the sun SN, and the half surface of the earth EH including the position P4 and the position P1. Is the daytime, and the half of the earth EH including the position P2 and the position P3 is at night. In this case, the power generation amount of the server facility 200-4 and the server facility 200-1 is larger than the power generation amount of the server facility 200-2 and the server facility 200-3. The server facility 200-4 and the server facility 200-1 are selected. That is, when the state shown in FIG. 6C changes to the state shown in FIG. 6D, the selection unit 131 selects the server equipment 200-1 as the server equipment 200 to be newly selected for operation, and stops. The server facility 200-3 is selected as the server facility 200 to be selected.

  In this case, the management control unit 132 operates the server equipment 300 of the server equipment 200-4 and the server equipment 200-1, and stops the server equipment 300 of the server equipment 200-2 and the server equipment 200-3. Specifically, when the state shown in FIG. 6C is changed to the state shown in FIG. 6D, the management control unit 132 provides the service provided by the server device 300 of the server equipment 200-3 to the server equipment. The server apparatus 300 is changed (moved) so as to be provided.

  As described above, when each of the plurality of server facilities 200 is arranged at a place where the peak position of the power generation amount that changes in response to the daily movement of the solar SN is different, the selection unit 131 performs the daily movement. Correspondingly, the server equipment 200 for operating the server device 300 is switched and selected.

As described above, the server system 1 according to the present embodiment includes the plurality of server facilities 200, the selection unit 131, the power supply control unit 133, and the management control unit 132. Each of the plurality of server facilities 200 includes a server device 300 and a power generation device 21 (for example, a solar power generation device) that generates power based on natural energy. The selection unit 131 selects the server facility 200 from among the plurality of server facilities 200 based on the power generation amount of the power generation device 21 so that the server device 300 provides a predetermined service. The power supply control unit 133 performs control so that the power generated by the power generation device 21 included in the server facility 200 selected by the selection unit 131 is supplied to the server device 300 included in the server facility 200 selected by the selection unit 131. . Then, the management control unit 132 operates the server device 300 included in the server facility 200 selected by the selection unit 131 and provides a predetermined service via the network NW.
Thereby, since the server system 1 according to the present embodiment selects the server facility 200 that operates the server device 300 based on the power generation amount of the power generation device 21, for example, the server facility 200 including the power generation device 21 with a large power generation amount. Can be operated with priority. Therefore, the server system 1 according to the present embodiment can effectively use the power generated by the power generation device 21. Moreover, since the server system 1 according to the present embodiment effectively uses the power generated by the power generation device 21, the influence on the natural environment can be reduced.

In the present embodiment, the selection unit 131 selects the server equipment 200 from the plurality of server equipments 200 in descending order of the power generation amount of the power generation device 21 so as to provide a predetermined service.
Thereby, the server system 1 according to the present embodiment can operate with priority on the server facility 200 including the power generation device 21 with a large amount of power generation. Therefore, the server system 1 according to the present embodiment can reduce the use of power of the commercial power system (commercial power supply 23), and thus can effectively use the power.

In the present embodiment, the selection unit 131 generates power more than the power generation amount of the power generation device 21 included in the server facility 200 in which the server device 300 is already operating out of the server facilities 200 in which the server device 300 is operating. A server facility 200 having a large amount is selected. The management control unit 132 is a server that is already in operation in the server facility 200 that has a smaller amount of power generation than the selected server facility 200. The device 300 is operated instead of the device 300.
Thereby, since the server system 1 according to the present embodiment switches to the server facility 200 with a larger amount of power generation and operates the server apparatus 300 to provide a predetermined service to the user, the server apparatus 300 operates stably. It is possible to make effective use of electric power.

In the present embodiment, the power generation device 21 periodically changes the power generation amount corresponding to the diurnal movement, and each of the plurality of server facilities 200 has a peak of the power generation amount that changes corresponding to the diurnal movement. They are located at different locations. And the selection part 131 switches and selects the server equipment 200 which operates the server apparatus 300 corresponding to a diurnal exercise | movement.
Thereby, the server system 1 by this embodiment can operate the server apparatus 300 only with the electric power which the electric power generating apparatus 21 generates.

A selection step, a power supply control step, and a management control step. In the selection step, the selection unit 131 selects the server facility 200 from among the plurality of server facilities 200 based on the power generation amount of the power generation device 21 so that the server device 300 provides a predetermined service. In the power supply control step, the power supply control unit 133 supplies the power generated by the power generation device 21 included in the server facility 200 selected in the selection step to the server device 300 included in the server facility 200 selected in the selection step. To control. In the management control step, the management control unit 132 operates the server device 300 included in the server facility 200 selected in the selection step, and provides a predetermined service via the network.
Thereby, the management method by this embodiment can use the electric power which the electric power generating apparatus 21 produces | generates effectively similarly to the server system 1, and can reduce the influence which it has on a natural environment.

[Second Embodiment]
Next, a server system 1 according to a second embodiment of the present invention will be described with reference to the drawings.
In the first embodiment, a case has been described in which all the server devices 300 included in the server facility 200 are collectively controlled. However, in the present embodiment, according to the amount of power generated by the power generation device 21. An example of changing the number of operating server apparatuses 300 will be described. In the present embodiment, information indicating the operating state of each server device 300 is added to the information stored in the management information storage unit 111, and the processing of the server device 300 unit is added to the processing of the selection unit 131 and the management control unit 132. Is different from the first embodiment described above. Since other configurations and operations are the same as those in the first embodiment, the different configurations and operations described above will be described here.

In the present embodiment, as shown in FIG. 7, the management information storage unit 111 includes “server facility ID”, “location information (latitude and longitude)”, “facility operating state”, and “server device ID”. , “Server operating state” is stored in association with each other.
FIG. 7 is a diagram illustrating a storage example of the management information storage unit 111 in the present embodiment.
In this figure, “server operating state” indicates whether each server apparatus 300 is operating. The “server equipment ID”, “position information (latitude, longitude)”, “facility operating state”, and “server device ID” are the same as those in FIG.

  In the example shown in FIG. 7, since the “server operating state” associated with the “server device ID” “SV001” is “operating”, the server device 300 corresponding to this “SV001” is operating. It is shown that. Further, since the “server operating state” associated with the “server device ID” “SV002” is “stopped”, it indicates that the server device 300 corresponding to this “SV002” is stopped. .

In addition, the management control unit 132 in the present embodiment performs the same processing as in the first embodiment, and changes the number of server devices 300 to be operated according to the power generation amount of the power generation device 21. For example, the management control unit 132 acquires the “current power generation amount (W)” from the power supply information storage unit 112 and calculates the number of server devices 300 that can be operated based on the acquired “current power generation amount (W)”. The management control unit 132 operates only the calculated number of server devices 300 that can be operated among the server devices 300 included in the server facility 200 selected for operation.
In addition, when the “current power generation amount (W)” changes, the management control unit 132 similarly calculates the number of server devices 300 that can be operated, and according to the calculated number of server devices 300 that can be operated, The number of server devices 300 to be operated is changed. That is, the management control unit 132 changes the number of server devices 300 operating in each server facility 200 so that the same number of server devices 300 can operate in the plurality of server facilities 200 as a whole so that a predetermined service can be provided. To do.

  For example, when the number of server devices 300 to be operated is decreased due to a decrease in the “current power generation amount (W)”, the selection unit 131 newly operates from the other server facilities 200 with the power generation amount of the own facility. A server facility 200 having a possible server device 300 is selected. Then, the management control unit 132 newly operates the number of server devices 300 corresponding to the above-mentioned reduced number of the server devices 300 that the server facility 200 selected by the selection unit 131 has, and In the server facility 200 in which the “power generation amount (W)” is reduced, the server devices 300 corresponding to the number of the above-described reduced numbers are stopped. In addition, the server apparatus 300 which operates newly may span a plurality of server facilities 200. That is, the selection unit 131 may select a plurality of server facilities 200 including the server device 300 that can be newly operated with the power generation amount of the own facility.

As described above, in the server system 1 according to the present embodiment, each of the plurality of server facilities 200 includes the plurality of server devices 300, and the management control unit 132 operates according to the amount of power generated by the power generation device 21. The number of server devices 300 to be changed is changed.
Thereby, since the server system 1 according to the present embodiment performs operation or stop control in units of the server device 300 according to the power generation amount of its own equipment, it is possible to reduce waste of the power generated by the power generation device 21. can do. Therefore, the server system 1 according to the present embodiment can more effectively use the power generated by the power generation device 21 as compared with the first embodiment.

[Third Embodiment]
Next, a server system 1 according to a third embodiment of the present invention will be described with reference to the drawings.
In the first and second embodiments, an example in which the server device 300 is operated by the power generated by the power generation device 21 has been described. However, the server device 300 is supplied from the commercial power source 23 (commercial power system) together with the power generated by the power generation device 21. It is also possible to operate the server apparatus 300 by using the electric power. In the present embodiment, an example will be described in which the server apparatus 300 is operated by using the power supplied from the commercial power supply 23 together with the power generated by the power generation apparatus 21.

  In the present embodiment, the information stored in the power supply information storage unit 112 and the processing of the selection unit 131 and the power supply control unit 133 are different from those in the first embodiment described above. Since other configurations and operations are the same as those in the first embodiment, the different configurations and operations described above will be described here.

In the present embodiment, as shown in FIG. 8, the power supply information storage unit 112 includes “server facility ID”, “maximum power generation amount (W)”, “current power generation amount (W)”, and “equipment power consumption”. (W) ”,“ temperature (° C.) ”,“ electricity discount period ”, and“ commercial power use state ”are stored in association with each other.
FIG. 8 is a diagram illustrating a storage example of the power supply information storage unit 112 in the present embodiment.
In this figure, “temperature (° C.)” indicates the temperature of the place where the server facility 200 is located. This “temperature (° C.)” is acquired by the power supply control unit 133 via the network NW at predetermined time intervals, and is stored in the power supply information storage unit 112 in association with the “server facility ID”. Note that the power supply control unit 133 may acquire this “temperature (° C.)” from the control device 25 via the network NW, or from a website that provides weather information such as weather forecasts. Also good.

Also, in this figure, the “electricity discount period” is a time zone during which the electricity charge is discounted at the place (region) where the server facility 200 is placed, for example, the place where the management server device 100 is placed. It is indicated by time. The “commercial power use state” indicates whether each server facility 200 is operating the server device 300 using the commercial power source 23. The “commercial power use state” is stored in the power supply information storage unit 112 by the power supply control unit 133.
In addition, since “server facility ID”, “maximum power generation amount (W)”, “current power generation amount (W)”, and “equipment power consumption (W)” are the same as those in FIG. Description is omitted.

  In the example illustrated in FIG. 8, the server facility 200 whose “server facility ID” is “S001” has an “electricity discount period” of “23: 00-07: 00” (period from 23:00 to 7:00). This indicates that the “commercial power use state” is “in use”. In addition, the server facility 200 whose “server facility ID” is “S002” has an “electricity discount period” of “8: 00-16: 00” (period from 8:00 to 16:00), "Status" indicates "Stopped". Here, “stopped” indicates that the commercial power source 23 is not used.

  In addition, the selection unit 131 in the present embodiment performs processing similar to that in the first embodiment, and selects the server facility 200 that operates the server device 300 using the commercial power supply 23. For example, when the server facility 200 selected for operation based on the power generation amount of the power generation device 21 cannot provide a predetermined service, the selection unit 131 sets the electricity rate or temperature at the location where the server facility 200 is installed. In response, the server facility 200 is selected from the plurality of server facilities 200. Specifically, in such a case, the selection unit 131 selects “server facility ID” in which “facility operating state” is “stopped” from among a plurality of “server facility IDs” stored in the management information storage unit 111. Is extracted. Furthermore, the selection unit 131 selects the “server facility ID” in which the “temperature (° C.)” stored in the power supply information storage unit 112 is less than or equal to a predetermined threshold from the extracted “server facility ID”, or the current time is , “Server equipment ID” included in the time zone shown in “Electricity discount period” is extracted. The predetermined threshold is a temperature that does not require power consumption such as cooling by an air conditioning facility. The selection unit 131 selects the server facility 200 corresponding to the “server facility ID” extracted from the power supply information storage unit 112 as the server facility 200 for operating the server device 300 using the commercial power supply 23.

  The power supply control unit 133 in the present embodiment performs processing similar to that in the first embodiment, and performs control for permitting use of the commercial power supply 23 for each server facility 200. For example, the power supply control unit 133 uses the commercial power source 23 selected by the selection unit 131 to control the control device 25 of the server facility 200 that operates the server device 300 via the communication unit 120 and the network NW. An instruction (command) permitting use of the power supply 23 is output. Thereby, the control apparatus 25 performs control which makes the switch part 24 an ON state (closed state). In addition, when the power supply control unit 133 outputs an instruction (command) permitting the use of the commercial power supply 23, the power supply control unit 133 changes the “commercial power supply use state” of the power supply information storage unit 112 to “in use”.

  In consideration of a case where the power generation amount of the power generation device 21 is reduced, the power supply control unit 133 operates according to the power consumption of the server device 300 that is operating and the power generation amount of the power generation device 21. The server apparatus 300 may be supplied with power from the commercial power system. For example, the power supply control unit 133 reduces the “current power generation amount (W)” of each server facility 200 stored in the power supply information storage unit 112 to a predetermined threshold value higher than “equipment power consumption (W)”. In such a case, an instruction (command) permitting use of the commercial power source 23 is output. In addition, for example, the power supply control unit 133 increases the “current power generation amount (W)” of each server facility 200 stored in the power supply information storage unit 112 and increases a predetermined threshold value higher than “equipment power consumption (W)”. Is exceeded, an instruction (command) for prohibiting the use of the commercial power source 23 is output. Thereby, the control apparatus 25 performs control which makes the switch part 24 an OFF state (open state). In addition, when the power supply control unit 133 outputs an instruction (command) for prohibiting the use of the commercial power supply 23, the power supply control unit 133 changes the “commercial power supply use state” of the power supply information storage unit 112 to “stopped”.

Next, the operation of the server system 1 in this embodiment will be described with reference to FIG.
FIG. 9 is a flowchart showing an example of the operation of the server system according to the present embodiment.
Here, as in the example shown in FIG. 5, an example in which the computer resources of each server device 300 are the same, and the maximum power generation amount of each server facility 200 and the number of server devices 300 are the same. explain.

In this figure, the processing from step S201 to step S204 is the same as the processing from step S101 to step S104 shown in FIG.
In subsequent step S205, the selection unit 131 determines whether or not a predetermined service can be provided. That is, the selection unit 131 determines whether or not all necessary predetermined services can be provided by the server device 300 that is currently operating based on the information stored in the management information storage unit 111. When the selection unit 131 can provide a predetermined service (step S205: YES), the process proceeds to step S208. If the selection unit 131 cannot provide a predetermined service (step S205: NO), the selection unit 131 advances the process to step S206.

  In step S <b> 206, the selection unit 131 selects a server facility that is operated by the commercial power source 23. That is, as described above, the selection unit 131 selects the server facility 200 from among the plurality of server facilities 200 according to the electricity rate or the temperature at the place where the server facility 200 is installed. That is, the selection unit 131 selects the server equipment 200 with a low potential charge or the server equipment 200 with a low temperature and not requiring power consumption by the air conditioning equipment.

  Next, the power supply control unit 133 supplies power to the server device of the server facility 200 selected by the selection unit 131 (Step S207). For example, the power supply control unit 133 allows the control device 25 of the server equipment 200 selected for operation to permit the use of the commercial power supply 23 and supplies the server device 300 with the power generated by the power generation device 21. As a result, the server apparatus 300 is supplied with power from both the commercial power supply 23 and the power generation apparatus 21.

  Next, the server apparatus 300 of the server facility 200 selected for operation is operated (step S208). That is, the management control unit 132 activates each server device 300 included in the server facility 200 selected for operation via the network NW, and executes a program for providing a predetermined service, for example, Provide services to users.

Next, in step S209, the selection unit 131 acquires the power generation amount of each server facility 200 again.
Next, the selection unit 131 determines whether it is necessary to change the operating server equipment 200 (step S210). If the selection unit 131 determines that the operating server facility 200 needs to be changed (step S210: YES), the selection unit 131 advances the process to step S211. In addition, when the selection unit 131 determines that it is not necessary to change the operating server equipment 200 (step S210: NO), the process returns to step S209, and the management server apparatus 100 performs the above-described processing at a predetermined time interval. Repeatedly. In addition, before returning a process to step S209, the electric power feeding control part 133 may perform control which switches permission and prohibition of the commercial power supply 23 according to the change in the electric power generation amount of each server equipment 200 which is operating. .

  The subsequent processing from step S211 to step S215 is basically the same as the processing from step S107 to step S111 shown in FIG. However, in the present embodiment, in step S212, the power supply control unit 133 causes the server device 300 to supply the power from the commercial power supply 23 as necessary together with the power generated by the power generation device 21. Further, after the process of step S215, the management control unit 132 returns the process to step S209.

  In the above-described example, the case where the selection unit 131 selects the server facility 200 from among the plurality of server facilities 200 according to the electricity rate or the temperature at the place where the server facility 200 is installed has been described. The server facility 200 may be selected from among the plurality of server facilities 200 according to the CO2 (carbon dioxide) emission conditions. In this case, for example, the selection unit 131 preferentially selects the server facility 200 in a place where the CO2 emission condition is loose.

As described above, in the server system 1 according to the present embodiment, the power supply control unit 133 operates according to the power consumption of the server device 300 that is operating and the power generation amount of the power generation device 21. Is supplied with power from a commercial power source 23 (commercial power system).
Thereby, the server system 1 according to the present embodiment enables the server apparatus 300 to provide a predetermined service stably even when, for example, the power generation amount of the power generation apparatus 21 is reduced.

Moreover, in this embodiment, the selection part 131 is the electric bill in the place where the server equipment 200 is installed, when the server equipment 200 selected based on the electric power generation amount of the electric power generating apparatus 21 cannot provide a predetermined service. The server facility 200 is selected from the plurality of server facilities 200 according to the carbon dioxide emission conditions or the temperature.
Thereby, the server system 1 according to the present embodiment can reduce the electricity bill (operating cost) for operating the server device 300 and reduce the influence on the natural environment.

[Fourth Embodiment]
Next, a server system 1 according to a fourth embodiment of the present invention will be described with reference to the drawings.
In the first to third embodiments, an example has been described in which the computer resources of each server device 300 are the same, and the maximum power generation amount of each server facility 200 and the number of server devices 300 are the same. However, it is possible to change these for each server facility 200 or for each server device 300. In the present embodiment, an example will be described in which the computer resources of each server device 300 are different, or the maximum power generation amount of each server facility 200 or the number of server devices 300 is different.

  In the present embodiment, the information stored in the management information storage unit 111 and the power supply information storage unit 112 and the processes of the selection unit 131 and the power supply control unit 133 are different from those in the first embodiment described above. Since other configurations and operations are the same as those in the first embodiment, the different configurations and operations described above will be described here.

In the present embodiment, as shown in FIG. 10, the management information storage unit 111 includes “server facility ID”, “location information (latitude, longitude)”, “facility operating state”, and “server device ID”. , “Server specification information” and “server operating state” are stored in association with each other.
FIG. 10 is a diagram illustrating a storage example of the management information storage unit 111 in the present embodiment.
In this figure, “server specification information” is information indicating computer resources which are specifications of each server device 300. Here, the “server specification information” includes “the number of CPUs”, “RAM (GB (gigabytes))”, “HDD (GB)”, “power consumption (W)”, and the like.
“Number of CPUs” indicates the number of CPUs and clock frequency (GHz) of the server apparatus 300, and “RAM (GB)” indicates the RAM capacity (memory capacity) of the server apparatus 300. “HDD (GB)” indicates the hard disk capacity of the server apparatus 300, and “power consumption (W)” indicates the power consumption of the server apparatus 300. The “server equipment ID”, “position information (latitude, longitude)”, “facility operating state”, and “server device ID” are the same as those in FIG.

  As shown in FIG. 10, in this embodiment, the computer resources of the server device 300 are different, and the management information storage unit 111 sets the information indicating the computer resource of each server device 300 as “server specification information” as “server specification information”. It is stored in association with the “server apparatus ID”.

Further, in this embodiment, the specifications of each server facility 200 are different, and the management information storage unit 111 has different values of “maximum power generation amount (W)” for each server facility 200 as shown in FIG. And “equipment power consumption (W)” are stored.
FIG. 11 is a diagram illustrating a storage example of the power supply information storage unit 112 in the present embodiment.
In the example illustrated in FIG. 11, the server facility 200 whose “server facility ID” is “S001” has “maximum power generation (W)” of “3000” and “equipment power consumption (W)” of “1000”. It is shown that. In addition, the server facility 200 whose “server facility ID” is “S002” indicates that “maximum power generation (W)” is “4000” and “equipment power consumption (W)” is “1500”. ing. Thus, in the present embodiment, the maximum power generation amount of each server facility 200 or the number of server devices 300 is different.

In addition, the selection unit 131 in the present embodiment selects the server facility 200 that operates based on the power generation amount of the power generation device 21 stored in the power supply information storage unit 112 and the power consumption of the server facility 200. For example, the selection unit 131 selects the server devices in order of increasing “current power generation amount (W)” from among a plurality of server facilities 200 in which “current power generation amount (W)” exceeds “equipment power consumption (W)”. The server facility 200 that operates 300 is selected.
Further, the selection unit 131 selects, based on information ("server specification information") indicating computer resources stored in the management information storage unit 111 when selecting a server device 300 to be operated or stopped for each server facility 200. Then, the server device 300 to be operated or stopped is selected so that a predetermined service can be provided. For example, when selecting a server device 300 to be newly operated, the selection unit 131 selects the server device 300 having a computer resource capable of executing a predetermined service to be provided.

As described above, in the server system 1 according to the present embodiment, the management information storage unit 111 stores “server facility ID”, “current power generation amount (W)”, and “facility power consumption (W)” in association with each other. To do. Then, the selection unit 131 selects the server equipment 200 to be operated based on the “current power generation amount (W)” and “equipment power consumption (W)” stored in the management information storage unit 111.
Thereby, even if the maximum power generation amount of each server facility 200 or the number of server devices 300 is different, the server system 1 according to the present embodiment appropriately selects the server facility 200 to be operated and the server facility 200 to be stopped. can do.

  In this embodiment, the management information storage unit 111 stores “server device ID” and “server specification information” in association with each other. Then, the selection unit 131 selects the server device 300 that operates and the server device 300 that stops based on the “server specification information” stored in the management information storage unit 111. Thereby, even if each server device 300 has different computer resources, the server system 1 according to the present embodiment can appropriately select the server device 300 to be operated and the server device 300 to be operated.

In the embodiment described above, the server apparatus 300 uses the physical machine 30. However, as illustrated in FIG. 12, the server apparatus 300 may be a virtual machine (virtual server 30a) that is a virtualized server apparatus. Good.
FIG. 12 is a block diagram illustrating a server apparatus 300a that is a modification of the server apparatus.
In this figure, the server device 300a includes a plurality of virtual servers 30a (30a-1, 30a-2, 30a-3,...). In the following description, the virtual servers 30a-1, 30a-2, 30a-3,... Have the same configuration and indicate any virtual server provided in the server system 1, or when they are not particularly distinguished. Will be described as the virtual server 30a.

The virtual server 30a is, for example, a virtualized server device (virtual machine), and each virtual server 30a corresponds to the server device 300 described above. Management control unit 132
When operating the virtual server 30a, the computer device (for example, CPU power, RAM capacity, HDD capacity, etc.) necessary for the server apparatus 300a is secured and the virtual server 30a is operated.
As described above, the server device 300 may include a virtual machine that is the virtualized server device 300. When the virtual server 30a is used as the server device 300, the physical machine 30 is used because there is no need to physically start or stop the server device 300a when the virtual server 30a is operated or stopped. Compared to the case, the server apparatus 300 can be moved quickly.

  For example, when the virtual server 30 a is used as the server device 300, the management control unit 132 may change the amount of computer resources used by the server device 300 according to the power generation amount of the power generation device 21. Thereby, since the server system 1 according to the present embodiment can be changed to an appropriate amount of computer resources in units of the server device 300 according to the power generation amount of its own equipment, it is possible to reduce unnecessary consumption of computer resources. In addition, it is possible to reduce waste of the power generated by the power generation device 21.

[Fifth Embodiment]
Next, a server system 1a according to a fifth embodiment of the present invention will be described with reference to the drawings.
In the first to fourth embodiments, the case where the server facility 200 that operates and stops the server device 300 is selected based on the power generation amount of the power generation device 21 has been described, but instead of the power generation amount of the power generation device 21. It is also possible to select the server equipment 200 that operates and stops the server device 300 based on the index value indicating the magnitude of the power generation amount. In the present embodiment, an example will be described in which the server equipment 200 that operates and stops the server apparatus 300 is selected based on an index value indicating the magnitude of the power generation amount.

FIG. 13 is a block diagram illustrating an example of the server system 1a according to the present embodiment.
As shown in this figure, the server system 1a includes a management server device 100a and a plurality of server facilities 200 (200-1, 200-2, 200-3,...). In this figure, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

In addition, the management server device 100a includes a storage unit 110, a communication unit 120, and a control unit 130a. The control unit 130a is, for example, a processor including a CPU and the like, and comprehensively controls the management server device 100a. In addition, the control unit 130 a includes a selection unit 131, a management control unit 132, a power supply control unit 133, and a power generation rate calculation unit 134.
The present embodiment is different from the first to fourth embodiments described above in that the management server device 100a includes a power generation rate calculation unit 134.

  The power generation rate calculation unit 134 calculates a power generation rate indicating an example of an index value indicating the magnitude of the power generation amount. Here, the power generation rate is, for example, the ratio of “current power generation amount (W)” to “equipment power consumption (W)” stored in the power supply information storage unit 112. The power generation rate calculation unit 134 calculates a power generation rate for each server facility 200 based on “facility power consumption (W)” and “current power generation amount (W)” stored in the power supply information storage unit 112, and calculates the generated power generation The power supply information storage unit 112 stores the rate in association with the “server equipment ID”.

FIG. 14 is a diagram illustrating a storage example of the power supply information storage unit 112 in the present embodiment.
In this figure, “equipment power generation rate (%)” indicates the power generation rate described above.
In the example illustrated in FIG. 14, the server facility 200 whose “server facility ID” is “S001” has “current power generation (W)” of “2500” and “equipment power consumption (W)” of “1000”. It is shown that. In this case, the “equipment power generation rate (%)” calculated by the power generation rate calculation unit 134 is “250”.
Thus, in the present embodiment, the power supply information storage unit 112 includes the “server facility ID”, “maximum power generation amount”, “current power generation amount (W)”, “equipment power consumption (W)”, The “equipment power generation rate (%)” is stored in association with each other.

  Note that the selection unit 131 according to the present embodiment uses the server equipment 200 to be operated and the server to be stopped based on the power generation rate (“equipment power generation rate (%)”) stored in the power supply information storage unit 112 instead of the power generation amount. The facility 200 is selected. For example, the selection unit 131 selects the server equipment 200 from the plurality of server equipments 200 in descending order of “equipment power generation rate (%)” so as to provide a predetermined service. Further, the selection unit 131 selects the “equipment power generation rate” from the “facility power generation rate (%)” of the server equipment 200 in which the server apparatus 300 is already operating from among the server equipment 200 in which the server apparatus 300 is not operating. A server facility 200 having a large (%) ”is selected.

  In addition, the management control unit 132 according to the present embodiment uses the server equipment 200 that has the server equipment 200 having a large “equipment power generation rate (%)” selected by the selection unit 131 to “capacity power generation” from the selected server equipment 200. The server apparatus 200 having the small “rate (%)” is operated instead of the already operating server apparatus 300.

Next, the operation of the server system 1a in this embodiment will be described with reference to FIG.
FIG. 15 is a flowchart showing an example of the operation of the server system 1a according to the present embodiment.
Here, an example will be described in which the computer resources of each server device 300 are the same, and the maximum power generation amount of each server facility 200 and the number of server devices 300 are the same.

In this figure, first, the management server device 100a acquires the power generation amount of each server facility 200 (step S301).
Next, the power generation rate calculation unit 134 calculates the power generation rate of each server facility 200 (step S302). That is, as described above, the power generation rate calculation unit 134 generates the power generation rate for each server facility 200 based on the “facility power consumption (W)” and the “current power generation amount (W)” stored in the power supply information storage unit 112. ("Equipment power generation rate (%)") is calculated, and the calculated power generation rate ("equipment power generation rate (%)") is stored in the power supply information storage unit 112 in association with the "server facility ID".

  Next, the selection part 131 selects the server equipment 200 which operates based on a power generation rate (step S303). Specifically, the selection unit 131 selects the server facility 200 from the plurality of server facilities 200 in descending order of the power generation rate of the power generation device 21 so as to provide a predetermined service. That is, the selection unit 131 selects the “equipment power generation rate (%)” of the power generation device 21 based on the “equipment power generation rate (%)” stored in the power supply information storage unit 112 from among the plurality of server facilities 200. The server equipment 200 that operates the server device 300 is selected in descending order.

The subsequent processing from step S304 to step S306 is the same as the processing from step S103 to step S105 shown in FIG.
Next, in step S307, the power generation rate calculation unit 134 calculates the power generation rate of each server facility 200 as in step S302 described above.
The subsequent processes from step S308 to step S313 are steps shown in FIG. 5 except that the power generation rate calculated by the power generation rate calculation unit 134 (“equipment power generation rate (%)”) is used instead of the power generation amount. Since it is the same as that from S106 to step S111, the description is abbreviate | omitted here.
In addition, after the process of step S313, the management control part 132 returns a process to step S306, and the management server apparatus 100a repeatedly performs the process mentioned above at a predetermined time interval.

As described above, in the server system 1a according to the present embodiment, the selection unit 131 has a large index value (for example, power generation rate) indicating the amount of power generation of the power generation device 21 so as to provide a predetermined service. In order, the server facility 200 is selected from the plurality of server facilities 200.
As a result, the server system 1a according to the present embodiment can effectively use the power generated by the power generation device 21 and reduce the influence on the natural environment, as in the first to fourth embodiments. it can.
The index value indicating the magnitude of the power generation amount is, for example, a power generation rate that is a ratio of “current power generation amount (W)” to “equipment power consumption (W)”. In this case, the power generation rate is an index value indicating the amount of power generation in consideration of the power consumption of the server facility 200. Therefore, the server system 1a according to the present embodiment can appropriately operate the server apparatus 300 in consideration of the power consumption of the server facility 200.

Moreover, in this embodiment, the selection part 131 is the said parameter | index rather than the index value (power generation rate) of the server equipment 200 in which the server apparatus 300 is already operating out of the server equipment 200 in which the server apparatus 300 is not operating. A server facility 200 having a large value is selected. Then, the management control unit 132 is already operating the server device 300 included in the server facility 200 having a large index value selected by the selection unit 131 and included in the server facility 200 having a smaller index value than the selected server facility 200. The server device 300 is operated instead of the existing server device 300.
Thereby, the server system 1a according to the present embodiment can operate with priority on the server facility 200 including the power generation device 21 having a large index value described above. Therefore, since the server system 1a according to the present embodiment can reduce the use of the power of the commercial power system (commercial power supply 23), the power can be used effectively.

In addition, the power storage device 26 supplies the stored power to the server device 300 or reversely flows to the commercial power supply 23 via a bidirectional AC / DC converter 27 described later.

  Bidirectional AC / DC converter 27 converts AC power flowing in supply line L1 into DC power and supplies it to power storage device 26 when storing power in power storage device 26 in accordance with an instruction from control device 25. To do. The electric power supplied from the bidirectional AC / DC converter 27 to the power storage device 26 is stored in the power storage device 26. Further, the bidirectional AC / DC converter 27 converts the DC power output from the power storage device 26 into AC power when the power is discharged to the power storage device 26 in accordance with an instruction from the control device 25, and supplies the power supply line. AC power is supplied to L1.

  The control device 25a (power storage control unit) causes the power storage device 26 to store a part of the power generated by the power generation device 21 or a part of the power supplied from the commercial power source 23, and the power generation amount of the power generation device 21 is predetermined. The power stored in the power storage device 26 is supplied to the server device 300 when the voltage drops below the threshold value. Here, the predetermined threshold is, for example, a value equal to or greater than the power consumption of the server facility 200a (“equipment power consumption (W)”). That is, when there is surplus power in the power generation amount of the power generation device 21, the control device 25 a outputs an instruction to store the power storage device 26 in the bidirectional AC / DC converter 27, and the power generation amount of the power generation device 21 is insufficient. If the power is present, the bidirectional AC / DC converter 27 outputs an instruction to supply power from the power storage device 26 to the supply line L1.

As described above, in the server system 1b according to the present embodiment, each of the plurality of server facilities 200 includes the power storage device 26 that stores electric power.

The control device 25a (power storage control unit) to be supplied to the server device 300 is provided.
Thereby, since the server system 1b according to the present embodiment can store the surplus power of the power generation device 21 in the power storage device 26, the power can be used more effectively. Moreover, since the server system 1b can supply electric power from the power storage device 26 to the server device 300 when the power generation amount of the power generation device 21 is insufficient, the server device 300 can be operated stably.

  Further, in the present embodiment, the server system 1b controls the power storage device 26 to an appropriate temperature at which the power can be stored by operating the server device 300 when the temperature is low to a level where the power storage of the power storage device 26 is difficult.
