Description

  The present invention relates to a computer processing device cooperation system, a control method thereof, a computer processing device, and a program that link a plurality of computer processing devices, and more particularly to power supply in the computer processing device cooperation system.

  Some calculation processing apparatuses such as blade systems are equipped with a LAN (Local Area Network) port for cooperation with other calculation processing apparatuses. By using this LAN port and connecting adjacent calculation processing apparatuses in a daisy chain with a LAN cable, information can be shared between the calculation processing apparatuses. In such cooperation, since adjacent calculation processing devices are connected in a daisy chain, when a power failure of some of the calculation processing devices or a failure of a LAN connecting the calculation processing devices affects the entire cooperation system There is also. Even in such a state, it is necessary to establish a method for managing the power supply of each computing device.

  In order to control the power supply of each calculation processing device in the linkage system, any one calculation processing device is used as a control server, and the power used by the calculation processing devices linked by the calculation processing device is collectively managed. Is desirable. In Patent Document 1, in one computer system of a computer system group, information on the power consumption of each computer system is acquired, and the total power consumption of each computer system exceeds the total power that can be supplied It is disclosed to control so as not to.

A method for supplying power to the calculation processing device is also disclosed in, for example, Patent Document 2.

  However, in the case where any one computer processing device is used as a server, in order to operate a certain computer processing device normally, not only the normal operation of the computer processing device as a server but also from the computer processing device to the server is possible. It is also a condition that all the calculation processing devices in the middle of the path are operating normally. Therefore, in a calculation processing device other than the server, data transmission / reception with the server cannot be performed if the calculation processing device in the middle of the path is not operating normally. A calculation processing apparatus that cannot secure a path to a calculation processing apparatus serving as a server cannot grasp the surplus power that is the difference between the usable power and the in-use power value, and cannot use the power. This is very inconvenient in terms of operation and has a problem with availability.

  In addition, in the case of a computing device as a server, if some LAN cables are disconnected or some computing devices are powered off or faulty, data cannot be transmitted / received before and after the relevant point. It becomes difficult to control. For example, it is not possible to determine whether the computing device using high power that was ahead of the disconnection point before the LAN cable disconnection is still operating after the disconnection or whether the power supply is disconnected before the disconnection point. Therefore, in the calculation processing device in front of the disconnection point, the server cannot determine whether or not additional power can be used in the future.

  As described above, in the conventional linkage system of calculation processing devices, when a failure occurs in the linked calculation processing devices or a LAN cable or the like connecting the calculation processing devices is disconnected, each calculation processing is performed depending on the situation. There has been a problem that power cannot be supplied to the apparatus.

  The present invention is capable of controlling the power supplied to each computing device according to the situation even when a failure occurs in the linked computing device or a disconnection of a wiring that links the computing device occurs. An object of the present invention is to provide a collaborative system for computer processing devices.

  One aspect of the linkage system of calculation processing apparatuses according to the present invention is that N (N ≧ 2) linked calculation processing apparatuses and the upper limit value of power supply set for the entire N calculation processing apparatuses Is a secondary value that is an upper limit value of power supplied to all of the N ′ (N ≧ N ′) recognized calculation processing devices among the N calculation processing devices. The control means for setting a static upper limit value, and setting an allocation upper limit value that is an upper limit value of the supply power for each of the recognized N ′ number of processing units based on the secondary upper limit value; It is characterized by providing.

  Moreover, one aspect of the control method of the cooperation system of the calculation processing devices according to the present invention is based on the overall upper limit value that is the upper limit value of the supply power set for the whole of the N calculation processing devices linked together. , Setting a secondary upper limit value that is an upper limit value of power supply for all of the N ′ (N ≧ N ′) recognized calculation processing devices among the N calculation processing devices, Based on the secondary upper limit value, an allocation upper limit value, which is an upper limit value of the supplied power, is set for each of the recognized N ′ calculation processing devices.

  In addition, according to one aspect of the calculation processing device according to the present invention, the N calculation processes are performed based on an overall upper limit value that is an upper limit value of supply power set for all of the linked N calculation processing devices. A secondary upper limit value, which is an upper limit value of power supply, is set for all of the recognized N ′ (N ≧ N ′) calculation processing devices among the devices, and based on the secondary upper limit value. And the control means for setting an allocation upper limit value, which is an upper limit value of supply power, to the computer processing apparatus of its own.

  Further, one aspect of the program according to the present invention is based on N upper limit values that are upper limit values of supply power set for the entire N calculation processing devices linked to each other. A secondary upper limit value, which is an upper limit value of power supply, is set for all of the recognized N ′ (N ≧ N ′) calculation processing devices, and based on the secondary upper limit value This is a program for causing a computer to execute a process of setting an allocation upper limit value, which is an upper limit value of power supply, for each of the recognized N ′ calculation processing devices.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described with reference to the accompanying drawings.

[First Embodiment]
FIG. 1 is a diagram illustrating an example of the overall configuration of a cooperation system 2000 of a calculation processing apparatus according to the first embodiment of the present invention. This calculation processing apparatus linkage system 2000 includes N (N ≧ 2) linked calculation processing apparatuses 10 and an overall upper limit that is an upper limit value of power supplied to the entire N calculation processing apparatuses 10. Based on the value, the secondary upper limit value that is the upper limit value of the supplied power is determined for the entire N ′ (N ≧ N ′) calculation processing devices 10 recognized among the N calculation processing devices 10. And a control unit 11 that sets and sets an allocation upper limit value that is an upper limit value of the supplied power for each of the recognized N ′ number of calculation processing devices 10 based on the secondary upper limit value.

  The N calculation processing devices 10 are connected to each other by being connected by a LAN (Local Area Network) cable or the like. Power is supplied to the N calculation processing devices 10 from a common power supply device 13. The upper limit value of power supplied from the power supply device 13 to the N calculation processing devices 10 is determined in advance as an overall upper limit value. The electric power supplied by the power supply device 13 is allocated to the N calculation processing devices 10.

  The control device 11 is configured to control the power supplied to the recognizable N ′ number of calculation processing devices 11. Here, the recognizable calculation processing device 10 refers to the calculation processing device 10 that can communicate with the control device 11, and the unrecognizable calculation processing device 10 refers to the calculation processing that cannot communicate with the control device 11. Let us refer to device 10.

  For example, if a failure occurs in some of the calculation processing apparatuses 10 and wirings that connect the calculation processing apparatuses 10 and the cooperation system 2000 is divided into two or more cooperation groups 12, as shown in FIG. The control means 11 of the linkage group 12 can recognize the calculation processing device 10 of the upper linkage group 12 but cannot recognize the calculation processing device 10 of the lower linkage group 12.

  The control unit 11 sets a secondary upper limit value that is an upper limit value of the power that can be supplied to the group 12 of the N ′ number of calculation processing apparatuses 10 that can be recognized. When no failure or disconnection has occurred in the linkage system 2000, the control unit 11 sets the overall upper limit value as the secondary upper limit value for the recognized N ′ = N calculation processing devices 10. Further, when a failure or disconnection occurs in the cooperation system 2000, the control unit 11 sets a secondary upper limit value for the N ′ (N ′ <N) calculation processing devices 10 that can be recognized.

  The secondary upper limit value is set based on the overall upper limit value. For example, the control unit 11 sets the overall upper limit value / N × N ′ as the secondary upper limit value of the cooperation group 12 of the recognized N ′ number of calculation processing apparatuses 10. In addition, as another method of setting the secondary upper limit value, the overall upper limit value is allocated in advance as the initial value of the supplied power in accordance with the scale, function, importance, etc. of each calculation processing device 10, and some When a failure occurs in the calculation processing device 10 or the wiring connecting the calculation processing devices 10, the sum of the pre-assigned initial values of the recognized calculation processing devices is set as the secondary upper limit value of the entire group 12. You can also

  Based on the secondary upper limit value, the control unit 11 sets an allocation upper limit value that is an upper limit value of the power supplied to each calculation processing device. When the power value in use of one calculation processing device 10 is larger than the allocation upper limit value, the control unit 11 subtracts the power value in use from the allocation upper limit value in another recognized calculation processing device 10. The surplus power value is allocated to the allocation upper limit value of one calculation processing device.

  The control means 11 may be provided in each calculation processing device 10 or may be provided in common for a plurality of calculation processing devices 10. Further, the control means 11 may be provided inside the calculation processing apparatus 10 or may be provided outside.

  FIG. 2 is a flowchart showing the operation of the cooperation system of the calculation processing apparatuses configured as described above. The control means 11 first acquires the overall upper limit value (S11). The overall upper limit value is set according to the maximum rated power of the power supply device 13 and the like. The control means 11 confirms a recognizable calculation processing device among the N linked calculation processing devices 10 (S12).

  And the control means 11 sets a secondary upper limit with respect to the whole group of the recognized computing device based on the whole upper limit (S13). In step S13, as described above, in addition to the overall upper limit value, the secondary upper limit value is based on information such as the number of recognized calculation processing devices 10 and initial values set in the calculation processing device 10. Can be set. Based on the secondary upper limit value, the control means 11 sets the allocated upper limit value of each recognized computing device 10 (S14).

  As described above, according to the embodiment of the present invention, the secondary upper limit value is set for each cooperation group 12 of the recognized calculation processing device 10 and the supply of the calculation processing device 10 is performed based on the secondary upper limit value. By controlling the power, the control unit 11 controls the power supply of each linkage group 12 even when a failure occurs in some of the calculation processing devices 10 or wirings that link the calculation processing devices 10. be able to.

  The present embodiment can be implemented as a program that operates in the control means 11. This program can be stored in various types of storage media, and can be transmitted via a communication medium. The storage medium includes, for example, a flexible disk, a hard disk, a magnetic disk, a magneto-optical disk, a CD-ROM (Compact Disc Read Only Memory), a DVD (Digital Versatile Disc), a ROM cartridge, a battery-backed RAM (Random Access Memory), Memory cartridges, flash memory cartridges, non-volatile RAM cartridges and the like are included. In addition, the communication medium includes a wired communication medium such as a telephone line, a wireless communication medium such as a microwave line, and the Internet.

[Second Embodiment]
Next, a configuration and operation when the first embodiment is applied to a blade system cooperation system will be described as a second embodiment. FIG. 3 is a diagram showing an example of the overall configuration of a linkage system 1000 for blade apparatuses according to the second embodiment of the present invention. The linkage system 1000 includes blade devices 101 to 104 each including a plurality of CPU (Central Processing Unit) blades in a casing. The blade devices 101 to 104 are linked to each other. Each of the plurality of blade devices 101 to 104 has an upper limit value of power usage allocated to itself based on an initial allocation upper limit value that is an upper limit value of power usage preset in the blade devices 101 to 104 including the recognized self. An allocation upper limit value is set. In the second embodiment, the sum of the initial allocation upper limit values set in advance for the recognized blade apparatuses 101 to 104 corresponds to the secondary upper limit value in the first embodiment.

  The CPU blade built in the blade devices 101 to 104 is a calculation processing device on which a CPU, a memory, and the like are mounted. The plurality of blade devices 101 to 104 are connected in a daisy chain by LAN cables 201 to 203. In the cooperation system 1000 shown in FIG. 3, a configuration in which four blade apparatuses 101 to 104 are connected by LAN cables 201 to 203 is shown as an example. Note that the number of blade devices 101 to 104 to be linked is not limited to four, and can be any number.

  Each blade device 101-104 includes control devices 701-704 and storage means 801-804. The storage units 801 to 804 store the number of linked blade apparatuses 101 to 104. In the present embodiment, since the four blade apparatuses 101 to 104 are linked, the number of linked units 301 to 304 is four.

  In addition, the storage units 801 to 804 store power that can be used in the entire blade device cooperation system 1000. This set value is assumed to be an overall upper limit value 401-404. In addition, the storage devices 801 to 804 store allocation upper limit values 501 to 504 as the maximum power consumption that can be used in the blade devices 101 to 104.

  The initial value of the allocation upper limit values 501 to 504 at the time of starting up each blade device 101 to 104 (hereinafter also referred to as the initial allocation upper limit value) is set to a value obtained by dividing the overall upper limit values 401 to 404 by the number of linked units 301 to 304. ing. Specifically, when the total upper limit values 401 to 404 are 10000 W and the number of linked units 301 to 304 is four, the initial value of the allocation upper limit value is 10000 ÷ 4 = 2500 W when the blade devices 101 to 104 are activated. The initial allocation upper limit value is not limited to a value obtained by dividing the overall upper limit value by the number of linked units, and can be set to an arbitrary value according to the function and scale of each of the blade devices 101 to 104.

  The control devices 701 to 704 acquire information stored in the storage units 801 to 804 of the other blade devices 101 to 104 via the LAN cables 201 to 203. The control devices 701 to 704 set their own allocation upper limit values 501 to 504 based on the acquired information on the other blade devices and the information stored in its own storage means.

  When new power is required in the blade devices 101 to 104 of its own, the control devices 701 to 704 add the power consumption that is newly required this time to the currently used power values 601 to 604 that are currently in use. If the value seems to exceed the allocation upper limit values 501 to 504, an attempt is made to borrow the insufficient allocation upper limit value from the recognized other blade apparatuses 101 to 104. If the required amount is borrowed, it is assumed that the power has been successfully secured, and the newly required power can be used. If the loan cannot be borrowed, it will be treated as a new one that cannot be used. Note that the recognized blade device refers to a blade device in which the other blade device has no failure and the LAN cable connecting the blade devices is not disconnected and can communicate normally.

  FIG. 4 is a flowchart showing the operation of the control devices 701 to 704 according to the embodiment of the present invention. First, the control devices 701 to 704 set allocation upper limit values 501 to 504 that are upper limit values of power that can be used as initial allocation upper limit values. As described above, the initial allocation upper limit value is power 2500W obtained by dividing the overall upper limit value 10000W by the number of linked units.

  Next, each of the control devices 701 to 704 determines whether or not the total allocation upper limit value of the recognizable blade devices 101 to 104 is equal to the total initial allocation upper limit value preset for the recognized blade devices 101 to 104. Confirm. Specifically, the control devices 701 to 704 satisfy the conditional expression “total of upper limit values of recognizable blade devices = total upper limit value ÷ number of linked units (N) × number of recognizable blade devices (N ′)”. It is determined whether or not (S2). If this conditional expression is not satisfied (NO in step S2), the process returns to step S1. That is, the control devices 701 to 704 reset the allocation upper limit value to the initial allocation upper limit value.

  On the other hand, if the above conditional expression is satisfied in step S2 (YES in step S2), are the in-use power values 601 to 604 in the blade apparatuses 101 to 104 larger than the assigned upper limit values 501 to 504? It is determined whether or not (S3). When the in-use power values 601 to 604 are less than or equal to the allocation upper limit values 501 to 504 (NO in S3), the process returns to step S2 to determine whether the conditional expression is periodically satisfied.

  If the in-use power values 601 to 604 are larger than the allocated upper limit values 501 to 504 (YES in S3), the process proceeds to step S4, and whether surplus power can be borrowed from the recognized other blade devices 101 to 104. Judge whether or not. Here, the surplus power is a value obtained by subtracting the in-use power values 601 to 604 from the allocation upper limit values 501 to 504 set in the blade apparatuses 101 to 104.

  If it is determined in step S4 that the surplus power can be borrowed from the recognized other blade apparatuses 101 to 104 (YES), the process proceeds to step S5, and the surplus power of the recognized other blade apparatus is allocated by itself. Assign to the upper limit. On the other hand, if it is determined in step S4 that surplus power cannot be borrowed from the recognized other blade apparatuses 101 to 104 (NO), the own operation state is shifted to the power saving mode (S6). For example, the power saving mode is a mode that operates at the initial allocation upper limit value.

  And it returns to step S4 and it is monitored whether surplus electric power can be borrowed from another blade apparatus. If the power that can be returned from the power saving mode to the normal operation mode can be covered by surplus power of other blade devices (YES in step S4), the surplus power is allocated to its own allocation upper limit (S5). ) Return to normal operation mode.

  Next, the above operation will be described with reference to a specific example. 5 and 6 are diagrams showing the operation of the cooperation system 1000 of the blade apparatuses 101 to 104 according to the embodiment of the present invention. In FIG. 5, a state 1-1 is a state immediately after the blade devices 101 to 104 are activated. The control devices 701 to 704 set the allocation upper limit values 501 to 504 of all the blade devices 101 to 104 to 2500 W that is the initial allocation upper limit value (step S1). The blade devices 101 to 104 have different in-use power values 601 to 604 depending on the type and number of devices to be mounted.

  In step S <b> 2, the control devices 701 to 704 determine whether or not the total allocation upper limit value of the recognizable blade devices 101 to 104 is equal to the total initial allocation upper limit value preset for the recognized blade devices 101 to 104. Confirm. Specifically, the control devices 701 to 704 determine whether or not the conditional expression “total of allocation upper limit values of recognizable blade devices = total upper limit value ÷ number of linked devices × number of recognizable blade devices” is satisfied. . In the state 1-1, since all the blade devices 101 to 104 and the LAN cables 201 to 203 are operating normally, in each blade device 101 to 104, all the other blade devices 101 to 104 associated with each other are connected. Be recognized.

  Therefore, in all the blade apparatuses 101 to 104, the left side of the conditional expression is 2500W + 2500W + 2500W + 2500W = 10000W. The right side of the conditional expression is 10000 W ÷ 4 × 4 = 10000 W. Therefore, in the state 1-1, the conditional expression is satisfied (YES in step S2). Next, it progresses to step S3 and it is determined whether the used electric power values 601-604 are larger than the allocation upper limit values 501-504.

  Here, in the state 1-1, when 300 W is required for the blade device 102, the in-use power value 602 is 2000 W, so even if 300 W is additionally used, the allocation upper limit value 502 is not exceeded (in step S3). NO). Therefore, the use of 300W is permitted, and the in-use power value 602 is 2300W as in the state 1-2.

  In the state 1-2, when the blade device 102 further requires 300 W, the in-use power value 602 is 2300 W + 300 W = 2600 W. Therefore, when 300 W is additionally used, the allocated upper limit value 502 in the state 1-2 is 2500 W. (YES in step S3). Therefore, it progresses to step S4 and it is determined whether the surplus electric power can be borrowed from another blade apparatus. When surplus power can be borrowed from another blade device (YES in step S4), the process proceeds to step S5, and the allocation upper limit value is borrowed from the other blade device.

  In the state 1-3-1, the blade device 102 borrows 100 W which is insufficient from the blade device 103. Thereby, the addition of the 300 W in-use power value is permitted. As a result, as shown in state 1-3-1, the allocation upper limit value 502 and the in-use power value 602 of the blade device 102 are 2600 W, and the allocation upper limit value 503 of the blade device 103 is 2400 W.

  Here, for example, when trying to transition from the state 1-2 of FIG. 5 to the state 1-3-1, if the blade device 101 is absent, that is, cannot be recognized from the blade device 102, for example, FIG. Transition is made as in state 1-3-2. That is, the blade device 102 borrows 100 W of the shortage from the blade device 103 from the blade device 103 regardless of the absence of the blade device 101. As a result, the allocation upper limit value 502 and the in-use power value 602 of the blade device 102 are 2600 W, and the allocation upper limit value 503 of the blade device 103 is 2400 W.

  Further, when the blade device 103 cannot be recognized by the blade device 102 when attempting to transition from the state 1-2 to the state 1-3-1 in FIG. 5, the blade device 103 is absent (see FIG. 6). State 1-3-3), and thus the blade device 104 cannot be recognized. In such a case, a shortage of 100 W is borrowed from the recognizable blade device 101. Accordingly, the allocation upper limit value 502 of the blade device 102 is 2600 W, and the allocation upper limit value 501 of the blade device 101 is 2400 W.

  Thus, according to the embodiment of the present invention, since any blade device is not a server, even if any blade device 101 to 104 is absent in the above state transition, each blade device depends on the situation. The device can set its own allocation upper limit value.

  Next, the operation when the conditional expression of step S2 is not satisfied will be described using FIGS. The state 2-1 is a state immediately after the blade devices 101 to 104 are activated. The control devices 701 to 704 set the allocation upper limit values 501 to 504 to 2500 W that is the initial allocation upper limit value (step S1). The blade devices 101 to 104 have different in-use power values depending on the type and number of devices to be mounted.

  In step S <b> 2, the control devices 701 to 704 satisfy the conditional expression “total of upper limit values of recognizable blade devices = total upper limit value ÷ number of linked devices (N) × number of recognizable blade devices (N ′)”. Determine whether or not. In the state 2-1, since all the blade devices 101 to 104 and the LAN cables 201 to 203 are operating normally, each control device 701 to 704 recognizes all the other blade devices 101 to 104 associated with each other. Is done. Therefore, the left side of the conditional expression is 2500W + 2500W + 2500W + 2500W = 10000W. The right side of the conditional expression is 10000 W ÷ 4 × 4 = 10000 W. Therefore, in the state 2-1, the conditional expression is satisfied (YES in step S2).

  Here, in the case of the state 2-1, when 1800W is required for the blade device 102, the in-use power value 602 of the blade device 102 is 2000W. Therefore, when the additional 1800W is used, the in-use power value 602 is 2000W + 1800W. = 3800W, which exceeds the allocated upper limit value of 502W (YES in step S3).

  Therefore, the blade device 102 needs to borrow an allocation upper limit value from the other blade devices 101, 103, and 104 (steps S4 and S5). Here, a shortage of 1300 W is borrowed from the blade device 103. Thereby, the addition of the in-use power value of 1800 W in the blade device 102 is permitted, and the allocation upper limit value 502 and the in-use power value 602 of the blade device 102 become 3800 W as in the state 2-2. In addition, the allocation upper limit value 503 of the blade device 103 is 1200 W.

  In the state 2-2, when 1100 W is required for the blade device 104, the in-use power value 604 is 2000 W, so if the additional 1100 W is used, the allocation upper limit value 504 is exceeded (YES in step S4). Therefore, it is necessary to borrow an allocation upper limit value from the other blade devices 101 to 103 (steps S4 and S5). Here, by borrowing 600 W which is insufficient from the blade device 103 and the blade device 101, the use of this 1100 W is permitted, and the allocation upper limit value 504 and the in-use power value 604 of the blade device 104 are 3100 W as in the state 2-3. Thus, the allocation upper limit value 503 of the blade device 103 is 1000 W, and the allocation upper limit value 501 of the blade device 101 is 2100 W.

  Assume that a LAN failure occurs between the blade device 103 and the blade device 104 in the state 2-3. FIG. 10 shows a state in which the LAN between the blade device 103 and the blade device 104 has failed. As a result, the cooperation system 1000 is divided into a cooperation group 901 of the linked blade apparatuses 101 to 103 and a cooperation group 902 including the blade apparatuses 104. This state is shown in state 2-4 in FIG.

  In the state 2-4, each blade device 101 to 104 checks whether or not the conditional expression “total allocation upper limit value of recognizable blade devices = total upper limit value ÷ number of linked devices × number of recognizable blade devices” is satisfied. (Step S2). For the blade devices 101 to 103 of the cooperation group 901, the conditional expression is “2100W + 3800W + 1000W ≠ 10000W ÷ 4 units × 3 units”. On the other hand, the blade device 104 of the cooperation group 902 is also “3100W ≠ 10000W ÷ 4 units × 1 unit”. That is, since the conditional expression does not hold in any of the cooperation groups 901 and 902, all the control devices 701 to 704 are NO in step S2, and return to step S1. That is, the allocation upper limit value of all the blade apparatuses 101 to 104 is reset to the initial allocation upper limit value 2500W. As a result, each blade device is in the state 2-5.

  In the state 2-5, the blade device 102 and the blade device 104 repeat steps S2 to S6. That is, the blade device 102 and the blade device 104 check whether or not the in-use power values 602 and 604 exceed the assigned upper limit values 502 and 504 that are regularly set for the blade device 102 and the blade device 104 (step S3). For the blade device 102, since the in-use power value 602 exceeds the allocated upper limit value 502, the allocated upper limit value is borrowed from the blade device 103 which is the same cooperation group 901 (steps S4 and S5).

  On the other hand, the blade device 104 of the cooperation group 902 shifts to the power saving mode (NO in step S4) because the allocation upper limit value cannot be borrowed from the blade devices 101 to 103 of the other cooperation group 901 (step S6). . This state is shown in state 2-6. For example, the power saving mode is a mode that operates at an initial value of 2500 W.

  In state 2-6, it is assumed that the LAN failure between the blade device 103 and the blade device 104 has been recovered. The recovered state is shown in state 2-7. In the state 2-7, each blade device 101 to 104 similarly repeats steps S2 to S6 to determine whether or not surplus power can be borrowed from another blade device (step S4). Specifically, the control devices 701 to 704 of the blade devices 101 to 104 periodically check the total surplus power (allocation upper limit value−in-use power value) of all the blade devices 101 to 104.

  Here, the total surplus power (allocation upper limit value−in-use power value) of all blade apparatuses is 700 W, which exceeds the amount of power (600 W) necessary to restore the power saving mode of the blade apparatus 104 ( YES in step S4). Therefore, the blade device 104 tries to recover from the power saving mode to the normal mode by allocating the surplus power of the other blade devices 101 to 103 to its own allocation upper limit value. In other words, the blade apparatus 104 is restored to the normal mode by borrowing the allocation upper limit value from the blade apparatus 103 and the blade apparatus 101. This final state is shown in state 2-8.

  As described above, according to the embodiment of the present invention, each blade device 101 to 104 controls power supply without using any blade device 101 to 104 as a server. It becomes possible to control the power supply of the entire apparatus. Specifically, in each of the blade devices 101 to 104, a part of the blade devices is set by setting its own assigned upper limit value based on the total of the initial assigned upper limit values of the recognizable blade devices (step S2 in FIG. 2). Even when a failure or the like occurs, each blade apparatus 101 to 104 controls the power consumed by itself according to the situation, with the allocation upper limit value previously allocated to the recognized blade apparatus as the minimum compensation value. be able to.

  In addition, each blade device sets an allocation upper limit value based on the total of the allocation upper limit values 501 to 504 of the currently linked blade devices (step S2 in FIG. 2), so that the initial allocation upper limit value that is the lowest compensation value is set. Can be determined for each cooperation group 901, 902 unit.

  Further, when the conditional expression “total allocation upper limit value of recognizable blade devices = total upper limit value ÷ number of linked units (N) × recognizable number of blade devices (N ′)” is not satisfied (NO in step S2), By resetting the allocation upper limit value of all the blade apparatuses 101 to 104 to the initial value, it is possible to allocate the entire upper limit value to each cooperation group 901 and 902 unit as one cooperation system, and to perform the respective power control.

  The present embodiment is not limited to the blade device cooperation system, and can be applied to any system.

  The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
