Description

  The present invention relates to a blade server, a power supply control method, and a power supply control program, and more particularly to a blade server that controls power consumption without using a power control management controller on the housing side.

  It has been a long time since computer networks became indispensable as business systems in the business of organizations such as companies. In addition to the increasingly sophisticated and large-scale processing that should be performed by the server computer that forms the core of the network, the operations of the client terminals used by each user are also handled by the virtual machine created inside the server computer. It has migrated.

  For this reason, blade servers are often used as a form of hardware capable of mounting a large number of server computers in a common housing at high density. Since the blade server has a power supply device, a cooling device, an external interface and the like mounted on the housing side, power consumption and operation cost can be reduced and maintenance workability is excellent. Furthermore, it is possible to improve the fault tolerance by making the hardware redundant.

  As long as one of the purposes used for blade servers is to reduce power consumption, efficient control of power consumption is of course essential. One of the main methods used for this purpose is a method in which a management controller for power control is mounted on both the chassis and each blade server, and both perform power control in cooperation. Another main technique is to allocate the maximum amount of power that can be used in each blade server when the blade server is powered on (powered on).

  There are the following technical documents related to this. Patent Document 1 describes a blade server power management system using a management controller on the housing side as power management that does not depend on an OS (basic software) or an application. Patent Document 2 describes a server device that performs load equalization between servers by interaction with a client terminal.

  Patent Document 3 describes a blade server that exchanges power information with other blades and determines its own operation mode based on it. Patent Document 4 describes an arithmetic processing device that is not a blade server but can determine an upper limit value of its own power consumption and operate within the range.

  Patent Document 5 describes a blade server system in which a power consumption control unit is provided in any one of a plurality of blade devices, thereby managing the overall power consumption. Patent Document 6 describes a power management system in which a service processor on the housing side sets an upper limit of power consumption of each blade server. Non-Patent Document 1 describes an outline of blade server products sold by the applicant.

“Blade Server (SIGMABLADE): Features”, [Search on February 25, 2013], NEC Corporation, Internet <URL: http://www.nec.co.jp/products/pcserver/blade/>

  In the blade server power consumption control method described above, the first method of “providing a management controller on the chassis side” enables efficient power consumption control in any case. Circuits and firmware must be installed, resulting in an increase in cost. In addition, when such a management controller is not mounted in a case of a blade server system that is already used, power consumption cannot be controlled.

  Furthermore, the power consumption in each blade server is not always constant, and can vary greatly depending on the contents of the processing to be executed. Depending on an execution request from a user or the like, suddenly high-load processing may be executed suddenly in a specific blade server, resulting in a rapid increase in power consumption. In the method of “allocating the maximum power amount that can be used when the power is turned on”, it is not possible to dynamically secure the additional maximum power amount in response to such a case. On the other hand, if a maximum amount of power with a margin is allocated in preparation for such an “absolute high load”, the allocation is wasted unless a high load state occurs.

  Techniques for solving the above-described problems are not described in the aforementioned Patent Documents 1 to 6 and Non-Patent Document 1. Patent Document 2 describes a technique that “a device that manages the whole (a management controller on the casing side is not required)”, but the client terminal actually plays the role of “managing the whole”. It's just that.

  The technique described in Patent Document 3 “exchanges power information with other blades” but only “determines its own operation mode” and corresponds to “suddenly high load”. I can't. Each of the other patent documents and non-patent documents also requires “an apparatus for managing the whole” in some form. Non-Patent Document 1 includes a function that requests the release of surplus power and an increase in supply power independently by the blade server according to the load status. By exchanging power information with the EM card, "Flexible power interchange can be realized", and this "EM card" corresponds to "the device that manages the whole".

  SUMMARY OF THE INVENTION An object of the present invention is to provide a blade server, a power supply control method, and a power that enable efficient power consumption control that can cope with an unexpectedly high load state without requiring a device for managing the whole. It is to provide a supply control program.

A controller, and the management controller acquires actual power consumption means for acquiring the amount of power actually consumed by the computer resource, and maximum power amount acquisition means for acquiring the maximum power amount that can be supplied by the power supply unit, When the acquired amount of power increases, the power consumption is acquired from other blade servers on the storage enclosure, and the own power amount and other blade servers are acquired. Having a parameter setting means for changing the power level of the total value of the power consumption as compared to the maximum amount of power, characterized by.

  In order to achieve the above object, a power supply control method according to the present invention is mounted on a storage housing having a common power supply unit, and is operated by receiving power supplied from the power supply unit. The blade server is provided with storage means for storing predetermined values corresponding to a plurality of power levels in advance as a power consumption table, and the amount of power actually consumed by the provided computer resources is realized. The parameter setting unit detects whether or not the acquired power amount is acquired by the power consumption acquisition unit, and the maximum power amount that can be supplied by the power supply unit is maximized when the power amount is increased. Acquired by the power amount acquisition means, the parameter setting means acquires the power consumption amount from other blade servers on the storage enclosure, and corresponds to the power level one level higher than the set current power level The parameter setting means compares the maximum power amount with the value obtained by adding the default value to the power consumption of other blade servers, and if the sum is less than or equal to the maximum power amount, the parameter setting means increases the power level by one level. The computer resource is operated by changing to the value of.

  In order to achieve the above object, a power supply control program according to the present invention is mounted on a storage case having a common power supply unit, and is a blade server that operates by receiving power supply from the power supply unit. The blade server is provided with storage means for storing predetermined values corresponding to a plurality of power levels in advance as a power consumption table, and the processor provided in the blade server actually consumes the computer resources provided.

  As described above, the present invention is configured to determine whether or not the power level can be changed from the power consumption obtained from the other blade server and the power consumption of itself. It becomes possible to operate by increasing its own power consumption. This makes it possible to perform efficient power consumption control that can cope with sudden high-load conditions without the need for a device that manages the entire blade server and power supply.

(Basic form)
Hereinafter, the basic configuration of the present invention will be described with reference to FIG.
First, the basic contents of the basic form will be described, and then more specific contents will be described.

Parameter setting means 4c for changing the power level.

As a result, the blade server 1 can efficiently control power consumption without requiring a device for managing the entire server.
A more detailed configuration of each unit / means will be described as the next embodiment.

(Embodiment)
Then, the structure of embodiment of this invention is demonstrated based on attached FIGS.
First, the basic content of the present embodiment will be described, and then more specific content will be described.
The blade server 10 according to the present embodiment is a blade server that is mounted on a storage case 50 including a common power supply unit 20 and operates by receiving power supply from the power supply unit. 13 is a power control unit 11 that controls the operating speed so that the amount of power used is within a predetermined value, and a management controller 12 that sets a power level corresponding to the specified value for the power control unit. With. The management controller 12 is acquired by an actual power consumption acquisition unit 101 that acquires the amount of power that is actually consumed by the computer resource, and a maximum power amount acquisition unit 102 that acquires the maximum amount of power that can be supplied by the power supply unit. Power consumption from other blade servers on the enclosure when the amount of power consumed increases, and the total value of own power consumption and power consumption of other blade servers is compared with the maximum power consumption. Parameter setting means 103 for changing the power level.

  Further, the management controller 12 has storage means 12b for storing predetermined values corresponding to a plurality of levels of power levels in advance as a power consumption table 112, and the parameter setting means 103 corresponds to a power level one level higher than the current level. And a function for changing the power level to a higher level when the value obtained by adding the predetermined value to the power consumption of other blade servers is equal to or less than the maximum power consumption.

  Further, the parameter setting means 103 of the management controller 12 determines that the other blade server when the value obtained by adding the predetermined value corresponding to the power level one step higher than the current power consumption amount of the other blade server is not less than the maximum power amount. A power release request is sent to. The storage unit 12b stores the power control priority indicating the priority in the power control process in advance, and the parameter setting unit 103 requests the power release to another blade server whose power control priority is lower than itself. Send.

  At the same time, the parameter setting means 103 of the management controller 12 also has a function of changing the power level to a lower value when the amount of power acquired by the actual power consumption acquisition means 101 decreases.

Thus, the blade server 10 can perform efficient power consumption control that can cope with an unexpectedly high load state without requiring a device for managing the entire server.
Hereinafter, this will be described in more detail.

  FIG. 2 is an explanatory diagram showing a configuration of the blade server system 100 in which a plurality of blade servers 10 according to the embodiment of the present invention are mounted. The blade server system 100 includes a plurality of blade servers 10a, 10b,... (Collectively referred to as blade server 10) and a plurality of power supply modules 21a, 21b,. The unit 20 is mounted and configured in a common storage housing 50. The number of blade servers 10 and power supply modules 21 is arbitrary.

  The blade servers 10 are connected to each other via a communication bus 30, and each blade server 10 and the power supply unit 20 are connected to each other via a management bus 40. The communication bus 30 is a general information communication line such as Ethernet (registered trademark), and the management bus 40 is a common line for transmitting and receiving control signals inside devices such as I2C and SMbus. In order to avoid complications in the drawings, the connection relating to the power supply between the blade server 10 and the power supply module 21 that are self-explanatory is not shown.

  Each blade server 10 includes a power control unit 11 and a management controller 12. The management controller 12 can transmit a request signal to the power supply unit 20 via the management bus 40 and receive a response signal thereto. Here, the management controller 12 can request the power supply unit 20 to “obtain the maximum amount of power that can be supplied” and “switch on / off the power output of each power supply module 21”. Is a point. This is a function that is normally provided in the enclosure of most blade server systems.

  The power supply unit 20 includes a power supply controller 22 in addition to each power supply module 21. In response to the request signal from the management controller 12, the power supply controller 22 returns the maximum amount of power that can be supplied (the amount of power supply that can be supplied per power supply module × the number of power supply modules whose power output is turned on) and responds to the request Accordingly, the power output of each power supply module 21 can be switched on / off.

  The power control unit 11 of each blade server 10 controls the operating speed of the computer resources 13 such as a processor, a main storage device, an external storage device, an external interface, etc. that perform normal processing as a server computer, and each blade server Control can be performed so that the power consumption of 10 falls within a predetermined value. This electric power control is an existing technique described in, for example, the above-mentioned Patent Documents 4 and 6. The specified value here can be specified by the management controller 12, which will be described later in detail.

  FIG. 3 is an explanatory diagram showing the configuration of the management controller 12 shown in FIG. 2 in more detail. The management controller 12 has a configuration as a computer that operates independently of the computer resource 13. That is, a processor 12a, which is a main body for operating a computer program, and storage means 12b for storing data are provided.

  The processor 12a acquires the maximum amount of power that can be supplied through the actual power consumption acquisition unit 101 and the control communication unit 12d that acquire the amount of power actually consumed by the computer resource 13 by the operation of the power control program. It operates as a parameter setting unit 103 that communicates with another blade server 10 via the maximum power amount acquisition unit 102 and the mutual communication unit 12c and determines parameters (details will be described later) related to the operation of its own power control unit 11.

  The storage unit 12b stores a power control priority 111, a power consumption table 112, and a power level 113 as parameters related to power control. FIG. 4 is an explanatory diagram showing more specific contents of the power control priority 111, the power consumption table 112, and the power level 113 shown in FIG.

  The power control priority 111 represents a priority in the power control process of each blade server 10. A blade server with a higher value can obtain power more preferentially than other blade servers. This numerical value can be changed from the outside. The power consumption table 112 stores a power level 112a and a power consumption upper limit 112b that can be used in accordance with each numerical value corresponding to the power level 112a in a table format.

  The power level 113 represents a numerical value of the power level 112a set for itself. The power consumption table 112 can be changed from the outside, and the power level 113 is a numerical value determined by the parameter setting means 103 (by an operation described later). In FIG. 4, the power control priority 111 is set in three steps and the power level 112a (113) is set in eight steps, but the number of steps is arbitrary.

  In the example illustrated in FIG. 4, when the blade server 10 is in a power-off state, the power level 112a = “8” and the power consumption upper limit 112b = “0”. When the blade server 10 is powered on, the parameter setting means 103 operates the power control unit 11 with the power level 112a (113) = “7” and the power consumption upper limit 112b = “120 W”. Thereafter, the parameter setting means 103 determines the value of the power level 112a (113), and operates the power control unit 11 with the power consumption upper limit 112b corresponding to this value.

  FIG. 5 is a flowchart showing processing when the blade server system 100 shown in FIG. 2 is turned on. The blade server 10 in the power-off state has the power level 113 = “8” (step S201). When a power-on request is generated for the blade server 10, the parameter setting unit 103 changes the power level 113 to “7” (step S 202), and performs the total power consumption acquisition process for the entire blade server system 100. This is performed (step S203, details are shown in FIG. 6).

  Since the total amount of power secured in the entire blade server system 100 is confirmed in the total power consumption acquisition process in step S203, the power consumption upper limit value 112b = corresponding to its own power level 113 = “7”. It is determined whether or not the value obtained by adding “120 W” is smaller than the maximum suppliable power amount acquired from the power supply controller 22 via the maximum power amount acquiring unit 102, that is, whether or not power supply is possible (step). S204).

  When power supply is possible (total power consumption + power consumption upper limit value corresponding to power level “7” ≦ suppliable power amount), the parameter setting unit 103 sets the power level 113 = “7” to the power control unit 11. Is set to the power-on state (step S205), and the computer resource 13 is operated at this power level (step S206). As a result, the blade server 10 performs the operation within the range up to the power consumption upper limit 112b = “120 W” of the power level 113 = “7”, and the process is ended.

  If power supply is impossible (total power consumption + upper limit of power consumption corresponding to power level “7”> power supply available), the parameter setting unit 103 releases power to other blade servers 10. Request processing is performed (step S207, details are shown in FIG. 7), and it is determined whether the power release is successful (step S208). If this is successful, the process returns to the determination in step S203 again, and the power of the blade server 10 can be turned on. If unsuccessful, it is determined that the power of the blade server 10 cannot be turned on (step S209), and the process ends with the power off.

  FIG. 6 is a flowchart showing details of the total power consumption acquisition process shown as step S203 in FIG. First, the parameter setting unit 103 of the blade server 10 (referred to as a request source) that has started this total power consumption acquisition process applies to all other blade servers 10 (referred to as request destinations) in the same blade server system 100. Then, a usage power information acquisition request is transmitted (step S251).

  Upon receiving this acquisition request, the parameter setting unit 103 of the request destination (step S261) acquires the power consumption upper limit 112b for its own power level 113 from the power consumption table 112 (step S262), and requests this as the response power amount. Reply to the original (step S263).

  The parameter setting unit 103 of the request source that has received replies from all the request destinations sums up the values of the response power received from all the request destinations (step S252), and sets this value as A. Next, the power consumption upper limit value 112b for the own power level 113 is acquired from the power consumption table 112 (step S253), and this value is set to B. Finally, A + B is output as the total power consumption for the next processing (step S254). This completes the total power consumption acquisition process.

  FIG. 7 is a flowchart showing details of the power release request process shown as step S207 in FIG. First, the parameter setting means 103 of the blade server 10 (referred to as a request source) that has started this total power consumption acquisition process supplies power to other blade servers 10 (referred to as request destinations) in the same blade server system 100. A control priority acquisition request is transmitted (step S301). Upon receiving this, the parameter setting unit 103 of the request destination reads its own power control priority 111 and returns it to the request source (step S311).

  The parameter setting unit 103 of the request source compares its own power control priority 111 with the power control priority returned from the request destination, and determines whether there is a blade server 10 having a lower priority than itself. Determination is made (step S302). If there is no blade server 10 having a lower priority than the self, this process ends abnormally as “power release process failure” (step S307). If there is a blade server 10 having a lower priority than that of itself, the parameter setting means 103 transmits a power release instruction to the blade server 10 (step S303).

  Upon receiving this power release instruction, the requested parameter setting means 103 first determines whether or not a power level lower than its current power level 113 exists in the power consumption table 112 (step S312). If not, “no power release is possible” is returned to the request source, and the process is terminated (step S313). If it exists, the power reduction process described later in FIG. 10 is executed (step S314), the operation at the power level 113 one level below is set for the power control unit 11, the computer resource 13 is operated, and “power release” is performed. “Possible” is returned to the request source, and the process is terminated (step S315).

  The parameter setting unit 103 of the request source waits for a response from the request destination and confirms the content (step S304), and if the response is “power release is possible”, completes the processing as “power release processing success”. (Step S305).

  If the response is “impossible to release power”, it is determined whether there is a blade server 10 with a lower priority than the blade server 10 other than the blade server 10 (step S306). A power release instruction is transmitted to the server 10. If it does not exist, it is determined as “power release processing failure” (step S308), and the process is terminated abnormally.

  Next, the power control operation of the blade server 10 after the power is turned on will be described. The actual power consumption acquisition unit 101 and the parameter setting unit 103 of the management controller 12 perform a process of acquiring the amount of power actually consumed by the computer resource 13 every predetermined time interval, and the value acquired there The power consumption is adjusted accordingly.

  FIG. 8 is a flowchart showing the power control operation performed by the blade server 10 in operation in the blade server system 100 shown in FIG. First, the actual power consumption acquisition means 101 determines whether or not it is in a power-off state (that is, power level 113 = “8”) (step S351). If it is in a power-off state, the process ends normally here. (Step S359).

  If the power is not off, the actual power consumption acquisition unit 101 acquires the amount of power actually consumed by the computer resource 13 (step S352). This is A. Subsequently, the current power consumption upper limit value 112b corresponding to its own power level 112a (113) and the power consumption upper limit value 112b corresponding to its own power level 112a (113) one step below are acquired from the power consumption table 112. (Steps S353 to 354). Let these be B and C, respectively.

  Then, from each acquired value, the parameter setting means 103 compares the set value of the power level 113 with the actual power consumption, and performs the following processing. Here, threshold values for determining “specified time”, “near the upper limit value”, and “near the lower limit value” are given in advance and can be arbitrarily set by the system administrator.

  First, when it is determined that A is changing at a value near B for a specified time or more (step S355), the power securing process shown in FIG. 9 is performed (step S356), and the process returns to step S351. Subsequently, when it is determined that A has changed at a value in the vicinity of C for a specified time or more (step S357), the power reduction process shown in FIG. 10 is executed (step S358), and the process returns to step S351. If it does not correspond to any of them, the process directly returns to step S351.

  FIG. 9 is a flowchart showing details of the power securing process shown in step S356 of FIG. The parameter setting means 103 confirms the current power level 113 and the power consumption upper limit 112b corresponding to the power level 112a (113) that is one step higher (steps S401 to S402), and then performs the same as in step S203 of FIG. Then, a total power consumption acquisition process is performed for the entire blade server system 100 (step S403, details are shown in FIG. 6).

  Then, the power consumption upper limit value 112b corresponding to the current power level 112a (113) of the user is subtracted from the total amount of power acquired, and the power consumption upper limit value corresponding to the power level 112a (113) that is one step higher than the current power level. It is determined whether or not the value obtained by adding the value 112b is smaller than the maximum suppliable power amount acquired from the power supply controller 22 via the maximum power amount acquisition unit 102, that is, whether or not power supply is possible (step S404). ).

  When power supply is possible (total power consumption-power consumption upper limit value corresponding to own current power level + power consumption upper limit value corresponding to power level one level higher than own current ≤ supplyable power amount) Then, the parameter setting means 103 sets the power level 113 as a value one step higher than the current value to the power control unit 11 (step S405), operates the computer resource 13 at this power level (step S406), and ends the processing. .

  Power supply is not possible (total power consumption-power consumption upper limit value corresponding to own current power level + power consumption upper limit value corresponding to power level one level higher than own current> supplyable power amount) In this case, the parameter setting unit 103 redoes the power release request process for the other blade server 10 (step S407, details are shown in FIG. 7), and determines whether the power release is successful (step S408). If this succeeds, the process returns to the determination in step S403 again, and the power level 113 of the blade server 10 can be set to a value higher than the current level. If unsuccessful, the power level 113 of the blade server 10 remains at the current value (step S409), and the process ends.

  FIG. 10 is a flowchart showing details of the power reduction process shown in step S314 of FIG. 7 and step S357 of FIG. The parameter setting unit 103 confirms the power consumption upper limit 112b corresponding to the power level 112a (113) that is one step lower than the current level (steps S451 to 452), and then performs power control with the power level 113 set to a value that is one step lower than the current level. Set to the unit 11 (step S453), operate the computer resource 13 at this power level (step S454), and terminate the process.

(Overall operation of the embodiment)
Next, the overall operation of the above embodiment will be described.
The power supply control method according to the present embodiment is provided in a blade server 10 that is mounted on a storage housing having a common power supply unit and operates by receiving power supply from the power supply unit. A storage means for storing a predetermined value corresponding to the power level of the stage in advance as a power consumption table, and an actual power consumption acquisition means for calculating the amount of power actually consumed by the provided computer resources Is acquired (FIG. 8, step S352), and the parameter setting means detects whether or not the acquired power amount is increasing (FIG. 8, step S356). The maximum power amount acquisition means acquires the maximum power amount that can be supplied by the unit, and the parameter setting means acquires the power consumption amount from other blade servers on the storage enclosure (see FIG. In step S403, the parameter setting unit compares a value obtained by adding the predetermined value corresponding to the power level one level higher than the set current power level with the power consumption amount of the other blade server and the maximum power amount (FIG. 9). Step S404) When the summed value is less than or equal to the maximum amount of power, the parameter setting means changes the power level to a value one level higher (FIG. 9, steps S405 to 406). If the total value is not less than or equal to the maximum power amount, the parameter setting means transmits a power release request to another blade server (FIG. 9, step S407).

  Further, when the acquired amount of power is reduced (FIG. 8, step S357), the parameter setting means changes the power level to a lower value (FIG. 8, step S358).

Here, each of the above-described operation steps may be programmed to be executable by a computer and executed by the processor 12a of the management controller 12 that directly executes each of the steps. The program may be recorded on a non-temporary recording medium, such as a DVD, a CD, or a flash memory. In this case, the program is read from the recording medium by a computer and executed.
By this operation, this embodiment has the following effects.

  According to the present embodiment, a controller is not required on the side of the storage enclosure, and no other device having a function as a controller is required, and a sudden high load due to the exchange between blade servers. It is possible to perform power control that can cope with the state. Therefore, this embodiment can be introduced only by changing a mounted blade server corresponding to this function even in a storage case without a controller.

  Further, according to the present embodiment, it is possible to dynamically change the distribution of the usable power amount according to the actual power consumption state. As a result, even if the blade system needs to be operated with a limited amount of power supply, power is temporarily allocated to a specific blade server that suddenly generates a high load. It is possible to dynamically execute such processing.

  Furthermore, according to the present embodiment, power control priority can be set for each blade server. For example, a blade server that places importance on performance sets a high priority and always gives priority to the required power. Such as securing the volume, conversely setting the low priority of low processing blade servers such as routine processing to lower the processing performance, and facilitating power interchange to other high processing blade servers Is possible.

(Extended embodiment)
As described above, each of the embodiments described so far can be extended in various ways without changing the gist thereof.
As described above, the power supply controller 22 of the power supply unit 20 can switch on / off the power output of each power supply module 21 as required.

  Therefore, in the power control process during operation described in FIG. 8, the total amount of power used + the total power consumption upper limit value corresponding to its current power level is compared with the amount of power that can be supplied. If the power supply is still possible even if one or more of the power supply units are turned off, an operation for requesting the power supply controller 22 to turn off the power supply module 21 for one unit may be added. On the other hand, when all the power supply modules 21 are not turned on and the power necessary for increasing the power level cannot be secured even if the power securing process is repeated, the power supply controller 22 is turned on for one power supply module 21. You may add an action requesting that
