Abstract

An SVP (2) measures the amount of time for which each PSU (8 to 11) has operated per PSU. In addition, the SVP (2) calculates the product of a working ratio, which is different for each of the PSUs (8 to 11), by the total value of the working time of a respective PSU (8 to 11), for each of the PSUs (8 to 11). Then, the SVP (2) selects, as power supply devices to be operated, PSUs in ascending order from the PCU with the lowest value obtained by subtracting a calculated value from the working time of each of the respective PSUs (8 to 11). Next, the SVP (2) operates the selected PSU, and suspends the other PSUs.

It has been.

Here, when the amount of hardware resources increases or decreases, or when the number of power supply devices to be activated is optimized by user operations, when operating servers and storage devices that are operated continuously for a long period of time In addition, there may be a power supply device that is not operated for a long time. However, when the power supply device is not operated for a long period of time, the electrolytic capacitor used for voltage conversion or the like deteriorates, and a failure is likely to occur. In order to prevent such deterioration of the electrolytic capacitor, a technique is known in which the operation time of each power supply device is monitored, and the power supply device with less accumulated operation time is preferentially operated.

Hereinafter, embodiments of a control device and a control method according to the present application will be described in detail with reference to the drawings. The disclosed technology is not limited by this embodiment. In addition, the embodiments may be combined as appropriate within a consistent range.

In the following first embodiment, an example of an information processing system having a control device will be described with reference to FIG. FIG. 1 is a diagram illustrating the information processing system according to the first embodiment. In the example illustrated in FIG. 1, the information processing system 1 includes an SVP (Service Processor) 2, a PSU (Power Supply Unit) group 3, and a hard resource group 4. The SVP 2 includes an MPU (Micro Processing Unit) 2a, a memory 2b, a flash memory 2c, and a hub 2d. Here, the hub 2 d has

communication terminals

5 and 6, and is connected to the user terminal 7 via the

communication terminals

5 and 6.

The PSU group 3 has a plurality of PSUs 8 to 11. Here, the PSU 8 has an FRU (Field-Replaceable Unit) 12, and the PSU 9 has an FRU 13. The PSU 10 has an FRU 14, and the PSU 11 has an FRU 15. The hard resource group 4 includes a plurality of SB (System Board) 16 to 19 and a plurality of IOB (Input Output Board) 20 to 23. The SB 16 includes a CPU (Central Processing Unit) 24 and a memory 25. Although not shown in FIG. 1, it is assumed that the other SBs 17 to 19 also have a CPU, a memory, and the like, similar to SB16.

Further, the IOB 20 includes an HDD (Hard Disk Drive) 26, a PCI (Peripheral Components Interconnect) card 27, and a hub 28. Although not shown in FIG. 1, it is assumed that the other IOBs 21 to 23 also have HDDs, PCI cards, hubs, etc., like the IOB 20. In the following description, the PSU 9 to PSU 11 are assumed to perform the same function as the PSU 8, and the description thereof is omitted. Further, SB17 to SB19 are assumed to perform the same function as SB16, and the description thereof is omitted. The IOBs 21 to 23 perform the same functions as the IOB 20 and will not be described.

First, the PSU 8 included in the PSU group 3 will be described. The PSU 8 is a power supply device that acquires power from the external power source 1 a, converts the acquired power, and supplies it to the hard resource group 4. For example, the PSU 8 converts an alternating current supplied from the external power source 1a into a direct current. Then, the PSU 8 increases or decreases the voltage of the direct current according to the device to which power is supplied, and supplies the direct current to the SBs 16 to 19 and the IOBs 20 to 23.

Moreover, PSU8 has FRU12. Here, the FRU 12 is a component installed in the PSU 8 and is a replaceable part. Further, the FRU 12 has a storage medium writable from the SVP 2 and can store arbitrary information written from the SVP 2.

Next, the hardware resource group 4 will be described. The hardware resource group 4 is hardware that operates with the power supplied from the PSU group 3. For example, the SB 16 is a base or rack mountable server that can be inserted into and removed from the housing of the information processing system 1 in which the hard resource group 4 is installed, and performs various arithmetic processing using the power supplied from the PSU group 3. Execute. Specifically, the CPU 24 installed in the SB 16 performs arithmetic processing using the data stored in the memory 25, and transmits the arithmetic result to an external device (not shown) via the IOBs 20-23.

The IOB 20 is a base or rack mountable housing on which an IO device used by each of the SBs 16 to 19 installed in the hardware resource group 4 is installed, and is hardware that operates with electric power supplied from the PSU group 3. . Specifically, the IOB 20 includes an HDD 26 that stores data used by the SBs 16 to 19 for arithmetic processing, a PCI card 27 that controls communication between the SBs 16 to 19 and an external device, and communication between the SBs 16 to 19, and each SB 16 to And a hub 28 for relaying 19 communications.

Next, SVP2 will be described. The SVP 2 is an information processing apparatus that controls various hardware installed in the information processing system 1, and is installed on a control board of the information processing system 1, for example. Specifically, the MPU 2a included in the SVP 2 is an information processing apparatus that executes programs such as firmware stored in the memory 2b and the flash memory 2c, which are storage media, and executes various control processes.

Specifically, the MPU 2a monitors the insertion / removal states of the SBs 16 to 19 and IOBs 20 to 23 included in the hardware resource group 4, and identifies the number of SBs and IOBs operating in the information processing system 1. can do. Further, the MPU 2a calculates the power consumed by the hardware resource group 4 from the number of SBs operating in the information processing apparatus system 1 and the number of IOBs, and calculates the number of PSUs that can supply the calculated power. Then, the MPU 2a selects the number of PSUs calculated from the PSUs 8 to 11, operates the selected PSU, and stops other PSUs.

Also, the MPU 2a measures the time when each of the PSUs 8 to 11 is operated, and selects the PSU to be operated so that the time when the PSUs 8 to 11 are operated is not the same. For example, the MPU 2a generates an operation ratio that is a ratio for operating the PSUs 8 to 11. Specifically, the MPU 2a generates the operation ratios of the PSUs 8 to 11 so that the operation ratios of the PSUs 8 to 11 have different values. Further, the MPU 2a measures the time when each of the PSUs 8 to 11 is operated, and calculates the product of the total time when each of the PSUs 8 to 11 is operated and the operating ratio of each of the PSUs 8 to 11, whereby the PSUs 8 to 11 are calculated. Calculate the ideal operating time.

Then, the MPU 2a calculates a value obtained by subtracting the calculated ideal operating time of each PSU 8-11 from the measured operating time of each PSU 8-11. After that, the MPU 2a has a smaller value obtained by subtracting the calculated ideal operating time of each PSU 8-11 from the measured operating time of each PSU 8-11, that is, the measured operating time is smaller than the ideal operating time. Select a short PSU with priority.

As a result, the MPU 2a makes the time when the PSUs 8 to 11 operate irregularly, so that it is possible to prevent the PSUs 8 to 11 from failing at the same time. That is, each of the PSUs 8 to 11 has a period during which normal operation is guaranteed, and after the period during which normal operation is guaranteed, a failure is likely to occur, so that it is replaced with a new PSU. However, when the PSUs 8 to 11 are operated at the same time, the PSUs 8 to 11 are replaced at the same time, and the information processing system 1 must be turned off.

Therefore, the MPU 2a selects a PSU to be operated from each of the PSUs 8 to 11 so that the operation time of each of the PSUs 8 to 11 is not uniform. As a result, the MPU 2a shifts the replacement timing and failure occurrence timing of the PSUs 8 to 11, so that the PSUs 8 to 11 can be replaced while the information processing system 1 is operating.

Next, the processing executed by the MPU 2a will be described in detail with reference to FIG. FIG. 2 is a diagram for explaining a functional configuration of the SVP according to the first embodiment. As shown in FIG. 2, the MPU 2 a includes a PSU operation instruction mechanism 32 and a hard resource monitoring unit 33. The memory 2b stores a hard resource power table 30 and a PSU operation management table 31. The hard resource monitoring unit 33 includes a power supply monitoring unit 34, a regular monitoring unit 35, an insertion / extraction monitoring unit 36, and a failure monitoring unit 37. The PSU operation instruction mechanism 32 includes a measurement unit 38, a calculation unit 39, a selection unit 40, and a control unit 41.

First, the tables 30 and 31 stored in the memory 2b will be described with reference to the drawings. The hard resource power table 30 stores the power consumed by the SBs 16 to 19 and the IOBs 20 to 23 included in the hard resource group 4. For example, FIG. 3 is a diagram for explaining an example of a hard resource power table. In the example illustrated in FIG. 3, the hardware resource power table 30 stores a hardware resource that consumes power and a power consumed by each piece of hardware in association with each other. For example, the hard resource power table 30 stores that one SB consumes “700 W (Watt)” and one IOB consumes “100 W”.

Referring back to FIG. 2, the PSU operation management table 31 is a table that stores information used by the MPU 2a when selecting a PSU to be operated from each of the PSUs 8 to 11. The PSU operation management table 31 is a table created when the MPU 2a selects a PSU to be operated, and information that is not stored in the memory 2b while the MPU 2a is not performing the selection process. is there.

Next, functions that the power monitoring unit 34, the regular monitoring unit 35, the insertion / removal monitoring unit 36, and the failure monitoring unit 37 of the hardware resource monitoring unit 33 exhibit will be described. The power monitoring unit 34 instructs the PSU operation instruction mechanism 32 to perform PSU selection processing when the information processing system 1 is turned on. For example, the power supply monitoring unit 34 monitors the operating state of the PSU group 3. When the PSU group 3 starts operation, the power supply monitoring unit 34 determines that the information processing system 1 has been turned on, and the PSU operation instruction mechanism 32. Is instructed to execute the selection process.

The regular monitoring unit 35 instructs the PSU operation instruction mechanism 32 to perform PSU selection processing at predetermined time intervals. For example, the periodic monitoring unit 35 has a timer that starts counting from when the power is turned on, and instructs the PSU operation instruction mechanism 32 to execute the PSU selection process when the count value of the timer reaches a predetermined value. To do. In addition, the periodic monitoring unit 35 resets the count value of the timer when the PSU operation instruction mechanism 32 executes the PSU selection process according to an instruction from the hardware resource monitoring unit 33.

The insertion / removal monitoring unit 36 selects a PSU in the PSU operation instruction mechanism 32 in accordance with the addition / removal of each SB 16-19, each IOB 20-23, and the addition / removal of each PSU 8-11 included in the hardware resource group 4. Instruct processing. For example, the insertion / removal monitoring unit 36 monitors the insertion / removal status of the SBs 16 to 19, the IOBs 20 to 23, and the PSUs 8 to 11 included in the hardware resource group 4. Then, when any of the new SB, IOB, or PSU is added to the hard resource group 4 or when the SB, IOB, or PSU is reduced, the insertion / extraction monitoring unit 36 notifies the PSU operation instruction mechanism 32. Instructs execution of PSU selection processing.

The failure monitoring unit 37 executes the PSU selection process to the PSU operation instruction mechanism 32 when the SBs 16 to 19, the IOBs 20 to 23, and the PSUs 8 to 11 included in the hardware resource group 4 are disconnected due to a failure. Instruct. For example, if any of the SBs 16 to 19, IOBs 20 to 23, or PSUs 8 to 11 of the hard resource group 4 is disconnected due to a failure by the disconnection process due to the failure, the failure monitoring unit 37 sends a PSU operation instruction mechanism 32 to the PSU operation instruction mechanism 32. Instructs execution of PSU selection processing.

Next, processing performed by the measurement unit 38, the calculation unit 39, the control unit 41, and the selection unit 40 included in the PSU operation instruction mechanism 32 will be described. The measuring unit 38 individually measures the time that each of the PSUs 8 to 11 is operating. And the measurement part 38 produces | generates the PSU operation management table 31 which stored the measurement result. Thereafter, the measurement unit 38 stores the observation result in each of the FRUs 12 to 15 included in each of the PSUs 8 to 11.

Hereinafter, the process executed by the measurement unit 38 will be described. The measurement unit 38 has a timer that counts the time that has elapsed since the PSU operation instruction mechanism 32 performed the PSU selection process. When the measurement unit 38 is instructed to execute the PSU selection process from the power source monitoring unit 34, the regular monitoring unit 35, the insertion / removal monitoring unit 36, and the failure monitoring unit 37 of the hard resource monitoring unit 33, each of the FRUs 12-15 Get the operation time stored in.

In addition, the measurement unit 38 calculates the cumulative operating time of each PSU 8 to 11 by adding the time counted by the timer to the operating time acquired from the FRU of the operating PSU. Then, the measurement unit 38 generates a PSU operation management table 31 in which the accumulated operation time of each PSU 8 to 11 is stored. Thereafter, the measuring unit 38 stores the updated accumulated operating time of each PSU 8 to 11 in each FRU 12 to 15 of each PSU 8 to 11.

Hereinafter, an example of processing executed by the measurement unit 38 will be described. In the following description, the operation time “1000 hours” is stored in the FRU 12, the operation time “800 hours” is stored in the FRU 13, the operation time “500 hours” is stored in the FRU 14, and the operation time “0 hours” is stored in the FRU 15. "Is stored. Further, it is assumed that PSU 9 and PSU 11 are operating and PSU 8 and PSU 10 are stopped.

For example, the measurement unit 38 acquires the operation time stored in each of the FRUs 12 to 15 when the PSU selection process is instructed from the regular monitoring unit 35. When the time counted by the timer is “100 hours”, the measuring unit 38 adds “100 hours” to the operating time acquired from the

FRUs

13 and 15 of the operating PSUs 9 and 11. Calculate the cumulative operating time of PSUs 8-11.

Here, FIG. 4A is a figure for demonstrating an example of the accumulation operation time which the measurement part measured. For example, the measurement unit 38 has a cumulative operating time of PSU 8 of “1000 hours”, a cumulative operating time of PSU 9 of “900 hours”, an operating time of PSU 10 of “500 hours”, and a cumulative operating time of PSU 11 Is “100 hours”. In addition, the measurement unit 38 stores “900 hours” in the FRU 13 of the PSU 9 that has been operating among the PSUs 8 to 11, and stores “100 hours” in the FRU 15 of the PSU 11.

And the measurement part 38 produces | generates the PSU operation management table 31 shown to FIG. 4B. FIG. 4B is a first diagram for explaining the PSU operation management table. As shown in FIG. 4B, the measurement unit 38 generates a PSU operation management table 31 in which the operation ratio, the operation time, the assumed time, and the time difference are associated with each other for each PSU 8-11.

Here, the operating ratio is an ideal ratio for operating the PSUs 8 to 11, and is a ratio that is different for each of the PSUs 8 to 11. The assumed time is an ideal time for operating each of the PSUs 8-11. The time difference is a value obtained by subtracting the assumed time from the operating time. Then, the measuring unit 38 stores the accumulated operation time of each PSU 8 to 11 in the operation time of the created PSU operation management table 31.

Note that, when the PSU operation management table 31 generated during the previous selection process is stored in the memory 2b, the measurement unit 38 uses the operation time, the assumed time, and the time difference among the information stored in the PSU operation management table 31. Erase. Then, the measurement unit 38 rewrites the operation time of each PSU 8 to 11 with a new operation time.

Further, when the operating time is not stored in each of the FRUs 12 to 15 such as when the information processing system 1 is shipped, the measuring unit 38 stores each operating time as “0” in each PSU operation management table 31. Then, the measurement unit 38 stores the operation time “0” in each of the FRUs 12 to 15. Further, for example, when the PSU 11 is removed due to a failure or when a new PSU is added, the measuring unit 38 newly updates the PSU operation management table 31 in which only the operation time of each PSU 8 to 10 is stored. To generate.

Returning to FIG. 2, when the measurement unit 38 stores the operation time in the PSU operation management table 31, the calculation unit 39 calculates the ideal operation time of each PSU 8 to 11 using the operation ratio of each PSU 8 to 11. To do. Then, the calculating unit 39 calculates the difference between the accumulated operating time of each PSU 8 to 11 and the ideal operating time. Here, the calculation unit 39 accumulates the PSUs 8 to 11 when the operation ratio of the PSUs 8 to 11 is not allocated, such as after the power-on of the information processing system 1 or when the PSU is added or removed. Depending on the operating time, the operating ratios with different values are calculated in stages.

Specifically, the calculation unit 39 refers to the PSU operation management table 31 and determines whether an operation ratio is set for each of the PSUs 8 to 11. Then, when the operation ratio is not set for each of the PSUs 8 to 11, the calculation unit 39 generates operation ratios having different values in stages and assigns them to PSUs having longer operation times in descending order of operation ratio. For example, when “n” PSUs are installed in the information processing system 1, the calculation unit 39 calculates the total value of integers from “1” to “n”, and “1” to “n”. The operation ratio is calculated by dividing the whole number up to the total value by the percentage. Then, the calculation unit 39 assigns an operation ratio with a larger value in order from the PSU with the longer operation time.

For example, FIG. 4C is a diagram for explaining processing for storing the operation ratio in the PSU operation management table. In the example shown in FIG. 4C, since the four PSUs 8 to 11 are installed in the information processing system 1, the calculation unit 39 calculates an integer total value “10” from 1 to 4. Next, the calculation unit 39 calculates the operation ratio “10%” by dividing “1” by “10”, the operation ratio “20%” by dividing “2” by “10”, and “3” by “10”. The operation ratio “40%” obtained by dividing the divided operation ratio “30%” and “4” by “10” is calculated.

Then, the calculation unit 39 assigns the largest operation ratio “40%” to the PSU 8 with the longest operation time, and sets the next largest operation ratio “30” to the PSU 9 with the next most operation time. % ". Further, the calculation unit 39 assigns the operation ratio “20%” to the PSU 10 and assigns the operation ratio “10%” to the PSU 11. Then, as shown in FIG. 4C, the calculation unit 39 stores the operation ratio assigned to each PSU 8 to 11 in the PSU operation management table 31.

Note that when the information processing system 1 is shipped or when new PSUs 8 to 11 are installed, the operation time of each PSU 8 to 11 becomes “0”. Therefore, when the operating time of each PSU 8 to 11 is “0”, the calculating unit 39 assigns a higher operating ratio in order from the PSU with the smallest number for identifying each PSU 8 to 11.

Next, the calculation unit 39 calculates the product of the sum of the operation times of the PSUs 8 to 11 and the operation ratio and the operation time assigned to each of the PSUs 8 to 11, and uses the calculated value as the assumed time for the PSU operation management table 31. To store. That is, the calculation unit 39 calculates the ideal operating time of each PSU 8 to 11 from the product of the operating ratio assigned to each PSU 8 to 11 and the total operating time of the written PSUs 8 to 11.

For example, FIG. 4D is a diagram for explaining a process of storing the assumed time in the PSU operation management table. First, the calculation unit 39 calculates the total operation time “2500 hours” that is the sum of the operation times of the PSUs 8 to 11. Next, the calculation unit 39 adds the calculated total excess time “2500 hours” to the operation ratios of the PSUs 8 to 11, and sets the result of the integration as the assumed time of the PSUs 8 to 11. In the example illustrated in FIG. 4D, the calculation unit 39 sets the assumed time of the PSU 8 to “2500 × 0.4 = 1000 hours” and the assumed time of the PSU 9 to “2500 × 0.3 = 750” hours. Further, the calculation unit 39 sets the assumed time of the PSU 10 to “2500 × 0.2 = 500 hours” and the assumed time of the PSU 11 to “2500 × 0.1 = 250” hours.

Next, the calculation unit 39 calculates the time difference obtained by subtracting the assumed time from the operating time of each PSU 8-11. That is, the calculation unit 39 calculates how many of the PSUs 8 to 11 are operating with respect to the ideal operating time. Then, the calculation unit 39 stores the calculation result in the PSU operation management table 31.

For example, FIG. 4E is a diagram for explaining processing for storing a time difference in the PSU operation management table. In the example illustrated in FIG. 4E, the calculation unit 39 stores a value “± 0” obtained by subtracting the assumed time “1000 hours” from the operation time “1000 hours” of the PSU 8 in the PSU operation management table 31 as the time difference of the PSU 8. Further, the calculation unit 39 stores a value “+150” obtained by subtracting the assumed time “750 hours” from the operation time “900 hours” of the PSU 9 in the PSU operation management table 31 as the time difference of the PSU 9.

Further, the calculation unit 39 stores a value “± 0” obtained by subtracting the assumed time “500 hours” from the operation time “500 hours” of the PSU 10 in the PSU operation management table 31 as the time difference of the PSU 10. Further, the calculation unit 39 stores a value “−150” obtained by subtracting the assumed time “250 hours” from the operation time “100 hours” of the PSU 11 in the PSU operation management table 31 as the time difference of the PSU 11.

Note that, when the accumulated operating time of each of the PSUs 8 to 11 does not exceed a predetermined threshold, the calculating unit 39 uses the value of the operating ratio as it is as the assumed time. For example, when the information processing system 1 is shipped and the accumulated operating hours of the PSUs 8 to 11 are all “0”, the calculating unit 39 sets the operating times to “40” hours, “30” hours, “20”, respectively. The time difference is calculated as “time” and “10” time.

Referring back to FIG. 2, the selection unit 40 selects a PSU to be operated based on the difference from the assumed operation time of each PSU 8-11. Specifically, the selection unit 40 calculates the number of PSUs to be operated according to the power consumed by the hardware resource group 4 installed in the information processing system 1 and the power that can be supplied by each of the PSUs 8 to 11. . Then, the selection unit 40 selects the calculated number of PSUs in ascending order of time difference stored in the PSU operation management table 31. Thereafter, the selection unit 40 notifies the control unit 41 of the selected PSU.

Hereinafter, processing executed by the selection unit 40 will be described using specific numerical values. In the following description, an example in which two

SBs

16 and 17 and two IOBs 20 and 21 are installed in the hardware resource group 4 will be described. For example, the selection unit 40 determines that the hard resource group 4 has two

SBs

16 and 17 and two IOBs 20 and 21. As a result, the selection unit 40 calculates the power consumption “700 × 2 + 100 × 2 = 1600 (W)” of the hard resource group 4 using the power consumption of the SB and the IOB stored in the hard resource power table 30.

Next, when one PSU has an output of 1000 W and the operation rate with good power conversion efficiency is “80%”, the selection unit 40 sets the number of PSUs to be operated “1600/1000 × 0.8 = 2 (unit) "is calculated. As a result, the selection unit 40 selects two PSUs in ascending order of time difference values. Here, when there are a plurality of PSUs having the same time difference, the selection unit 40 preferentially selects a PSU having a shorter accumulated operation time.

For example, when the information shown in FIG. 4E is stored in the PSU operation management table 31, the selection unit 40 selects the PSU 11 as the first PSU. Next, the selection unit 40 selects PSU 8 or PSU 10 as the second candidate, but since PSU 10 has a shorter cumulative operating time than PSU 8, PSU 10 is selected as the second generation PSU. Then, the selection unit 40 notifies the control unit 41 of PSU 10 and PSU 11.

2, the control unit 41 operates the PSU selected by the selection unit 40 and stops other PSUs. For example, when the notification of the PSU 10 and the PSU 11 is received from the selection unit 40, the control unit 41 operates the PSU 10 and the PSU 11 and supplies power to the hard resource group 4. Moreover, the control part 41 reduces power consumption by stopping operation | movement of PSU8 and PSU9.

As described above, the SVP 2 calculates the ideal operation time of each PSU 8 to 11 using the operation ratio that is different for each PSU 8 to 11, and calculates the ideal operation time and the actual accumulated operation time of each PSU 8 to 11. The PSU to be operated is selected on the basis of the difference. For this reason, the SVP 2 shifts the cumulative operating time of the PSUs 8 to 11 while reducing the power consumption of the information processing system 1, thereby preventing simultaneous failure of the PSUs 8 to 11 and simultaneous replacement of the PSUs 8 to 11. it can. As a result, the SVP 2 can exchange the PSUs without stopping the operation of the information processing system 1, so that stable operation can be achieved.

Next, a process for selecting a PSU to be newly operated by the SVP 2 after a certain period of time will be described with reference to FIGS. 5A and 5B. In the following description, an example will be described in which the SVP 2 executes the selection process when one week has passed since the previous selection process and the periodic monitoring unit 35 instructs the execution of the selection process.

First, the accumulated operation time of each PSU 8 to 11 after one week will be described with reference to FIG. 5A. FIG. 5A is a diagram for explaining the transition of the accumulated operation time. As shown in FIG. 5A, the SVP 2 calculates that the accumulated operating time of the PSU 10 after one week is “668” hours and the accumulated operating time of the PSU 11 is “268” hours. Then, the SVP 2 stores “668” time in the FRU 14 of the PSU 10 and stores “268” time in the FRU 15 of the PSU 11. Since SVP2 does not operate PSU8 and PSU10, it does not store new accumulated operating time.

Next, a process for selecting a PSU to be newly activated after one week will be described with reference to FIG. 5B. FIG. 5B is a diagram for describing processing for selecting a PSU to be newly operated. As shown in FIG. 5B, the SVP 2 assigns the same operation ratio to the PSUs 8 to 10 as before, and stores the new accumulated operation time of each PSU 8 to 10 in the PSU operation management table 31 as the operation time.

The SVP 2 calculates the assumed times “1134”, “850”, “567”, and “283” for each PSU 8-10. Further, the SVP 2 calculates the time differences “−134” time, “+50” time, “+101” time, and “−15” time of the PSUs 8 to 10. As a result, the SVP 2 selects two PSUs 8 and PSUs 11 having time difference values smaller than those of other PSUs. Thereafter, the SVP 2 operates the PSU 8 and the PSU 11 and stops the PSU 9 and the PSU 10.

Next, the flow of processing executed by the SVP 2 will be described with reference to FIG. FIG. 6 is a diagram for explaining the flow of processing executed by the SVP. For example, in the example shown in FIG. 6A, the cumulative operating time of PSU 8 is “1000” hours, the cumulative operating time of PSU 9 is “900” hours, and the cumulative operating time of PSU 10 is “500” hours. Yes, the accumulated operating time of the PSU 11 is “100” hours. Also, the operating ratio “40”% is assigned to PSU 8, the operating ratio “30”% is assigned to PSU 9, the operating ratio “20”% is assigned to PSU 10, and the operating ratio is assigned to PSU 11. “10”% is allocated.

Here, as shown in FIG. 6B, when there is an instruction to turn on the information processing system 1, the SVP 2 consumes each

16, 17 and each

IOB

20, 21 from the hard resource power table 30. Get power. Then, the SVP 2 calculates the total power amount “1600 W” of the hard resource group 4 by summing the acquired power consumptions as shown in FIG.

Next, as shown in FIG. 6D, the SVP 2 calculates the total operating time “2500” hours from the cumulative operating time of each PSU 8-11. Then, the SVP 2 calculates the assumed time of each of the PSUs 8 to 11 as shown in FIG. 6E by calculating the product of the operating ratio of each of the PSUs 8 to 11 and the total operating time. Specifically, the SVP 2 calculates an assumed time “1000” time of the PSU 8, an assumed time “750” time of the PSU 9, an assumed time “500” time of the PSU 10, and an assumed time “250” time of the PSU 11.

Next, as shown in FIG. 6F, the SVP 2 calculates a time difference obtained by subtracting the operation time from the assumed time of each PSU 8-11. Specifically, the SVP 2 calculates the time difference “0” of the PSUs 8 and 10, the time difference “+150” of the PSU 9, and the time difference “−150” of the PSU 11. As a result, the SVP 2 stops the PSU 8 and PSU 9 as shown in (G) of FIG. 6, and operates the PSU 10 and PSU 11 as shown in (H) of FIG.

Further, the SVP 2 generates the PSU operation management table 31 shown in (I) of FIG. 6 by executing the same processing as (C) to (F) in FIG. 6 after one week. As a result, the SVP 2 stops the PSU 9 and PSU 10 shown in (J) in FIG. 6, and operates the PSU 8 and PSU 11 shown in (K) in FIG.

Next, the flow of selection processing executed by the SVP 2 will be described with reference to FIG. FIG. 7 is a flowchart for explaining the flow of the selection process. For example, in the example shown in FIG. 7, the SVP 2 determines the number of PSUs to be operated (step S1). Next, the SVP 2 acquires the operation time from each PSU (step S2). Subsequently, the SVP 2 calculates the operation ratio of each PSU (step S3). Further, the SVP 2 calculates an assumed time for each PSU (step S4). Then, the SVP 2 calculates the time difference between the operating time of each PSU and the assumed time (step S5), determines the PSU to be operated using the calculation result (step S6), and ends the process.

Next, referring to FIG. 8, when the information processing system 1 is turned on, and when SB (System Board) 16-19, IOB (Input Output Board) 20-23, and PSU 8-11 are inserted / removed, A flow of processing executed by the SVP 2 will be described. FIG. 8 is a flowchart for explaining the flow of processing executed by the SVP when power is turned on and when a hard resource is inserted or removed. When the power of the information processing system 1 is turned on or when the SBs 16 to 19, IOBs 20 to 23, and PSUs 8 to 11 are inserted / removed, the SVP 2 confirms the hardware resources to be turned on, and the hardware resource power table 30 From this, the required power is calculated (step S101).

Next, the SVP 2 calculates the number of PSUs necessary for supplying the power calculated in Step S101 (Step S102). Next, the SVP 2 reads the operation time from the PSU and stores it in the PSU operation management table 31 (step S103). Subsequently, the SVP 2 determines an operation ratio of each PSU (step S104), and determines an assumed time from the determined operation ratio and the total operation time of each PSU (step S105).

For example, when the PSU is removed, the SVP 2 recalculates the operation ratio of the remaining PSU and assigns the recalculated operation ratio. Further, when the operating time of each PSU does not satisfy a predetermined threshold, the SVP 2 uses the operating ratio of each PSU as it is as an assumed time. Further, when a PSU is added, the SVP 2 recalculates the operation ratio of all PSUs including the newly added PSU, and assigns the recalculated operation ratio.

Subsequently, the SVP 2 calculates a time difference obtained by subtracting the operation time from the assumed time in the PSU operation management table 31 (step S106). Then, the SVP 2 selects the number of PSUs calculated in step S102 in order from the PSU having the smallest time difference (step S107). Note that when there are a plurality of PSUs having the same time difference, the SVP 2 preferentially selects a PSU with a short operation time. Then, the SVP 2 turns on the power supply of the selected PSU (step S108) and turns off the power supply of the other PSUs (step S109). Thereafter, the SVP 2 stores the operation time in the FRU of each PSU (step S110) and ends the process.

Next, the flow of processing executed by the SVP 2 when the regular monitoring unit 35 instructs execution of the selection processing or when the failure monitoring unit 37 instructs execution of the selection processing will be described with reference to FIG. FIG. 9 is a flowchart for explaining the flow of selection processing that is periodically executed and selection processing that is executed when a failure occurs. Of the processes shown in FIG. 9, step S201 and step S202 are the same as steps S101 and S102 in FIG. Further, since steps S205 to S211 in FIG. 9 are the same processes as steps S104 to S110 in FIG.

For example, the SVP 2 reads the operation time from each PSU and stores it in the PSU operation management table 31 (step S203). Then, the SVP 2 updates the operating time of the operating PSU (Step S204) and executes the process of Step S205. That is, in the selection process based on the periodic monitoring or the failure monitoring, the operation time stored in the FRUs 12 to 15 of the PSUs 8 to 11 is updated, and the selection process is executed using the updated operation time.

[Effects of SVP2]
As described above, the SVP 2 measures the time for which each of the PSUs 8 to 11 is operating for each PSU. Further, the SVP 2 calculates the product of the operation ratio that is different for each PSU 8 to 11 and the total operation time of each PSU 8 to 11 for each PSU. Then, the SVP 2 selects the PSUs to be operated in order from the PSU having the smallest calculated product value, operates the selected PSUs, and stops the other PSUs.

For this reason, the SVP 2 can shift the operation time of the PSUs 8 to 11, so that simultaneous failure of the PSUs 8 to 11 can be prevented. As a result, the SVP 2 can replace the PSUs 8 to 11 in units of units without stopping the information processing system 1, thereby realizing stable operation. Further, since the SVP 2 rotates the PSU to be operated according to the operation ratio, it is possible to prevent the PSUs 8 to 11 from being stopped for a long time. As a result, the SVP 2 can improve the service life of each PSU 8-11.

Also, the SVP 2 generates a plurality of operation ratios having different values in stages, and sequentially assigns the operation ratios with the larger values in order from the PSU having the longer operation time. As a result, since the SVP 2 preferentially uses the PSU having a long operation time, it is possible to prevent a situation in which a stopped PSU, that is, a PSU that performs backup cannot be used due to a failure.

Also, the SVP 2 selects as many PSUs as the PSUs to be operated according to the power consumed by the hardware resource group 4 and the power that can be supplied by each PSU. For this reason, the SVP 2 can reduce useless power consumed by the information processing system 1.

In addition, when there are a plurality of PSUs having the same calculated time difference, the SVP 2 preferentially operates the PSU having a short operation time. For this reason, the SVP 2 can prevent only the PSU having a long operation time from being selected again and generating a PSU that does not operate for a long period of time.

In addition, the SVP 2 stores the operation time of each PSU 8 to 11 in the FRU 12 to 15 included in each PSU 8 to 11. When the SVP 2 selects a PSU to be newly operated, the SVP 2 reads the operation time stored in each of the PSUs 8 to 11 and calculates the time elapsed since the previous selection process was performed on the operation time read from the PSU that was operating. By adding, the operating time is calculated. For this reason, the SVP 2 can accurately grasp the operation time even when the PSUs 8 to 11 are replaced. In addition, since the SVP 2 stores the operation time in the FRUs 12 to 15 of the PSUs 8 to 11, it is possible to easily determine whether or not to perform preventive replacement of each PSU.

In addition, the SVP 2 is newly operated when the information processing system 1 is turned on, when each of the PSUs 8 to 11 or the hardware resource group 4 fails, or when expansion or removal occurs due to insertion or removal, or at a predetermined time interval. Select a PSU. For this reason, the SVP 2 can switch the PSU to be operated while stably operating the information processing system 1.

Although the embodiments of the present invention have been described so far, the embodiments may be implemented in various different forms other than the embodiments described above. Therefore, another embodiment included in the present invention will be described below as a second embodiment.

(1) About the operation ratio In the above-described first embodiment, the operation ratios having different values in a linear manner are assigned in the order in which the operation times of the PSUs 8 to 11 are long. However, the embodiment is not limited to this. In other words, if the SVP 2 can set different operating times for the PSUs 8 to 11, it can set an arbitrary operating time such as an operating ratio with a non-linearly different value. In the information processing system 1, the process of selecting the operating PSUs 8 to 11 is performed, for example, on a weekly basis. Therefore, the difference between the assumed times of the PSUs 8 to 11 is set to be at least one week. Is desirable.

Also, the SVP 2 may increase the difference in the operation ratio allocated to each PSU 8-11 as the operation time of each PSU 8-11 extends. For example, FIG. 10 is a diagram for explaining an example of the operation ratio. For example, since SVP2 has a low possibility of failure during the operation time of each PSU 8-11 from 0 hours to 30,000 hours, the operation time “25”% is allocated to each PSU 8-11 and is operated evenly. . In addition, the SVP 2 gives a slight difference in the operation ratio of the PSUs 8 to 11 until the operation time of the PSUs 8 to 11 exceeds 30,000 hours and reaches 45,000 hours. For example, in the example illustrated in FIG. 10, the SVP 2 assigns an operation ratio “29”% to the PSU 8, assigns an operation ratio “27”% to the PSU 9, assigns “23”% to the PSU 10, and assigns “21”% to the PSU 11. assign.

Further, when the operating time of each PSU 8-11 exceeds 45,000 hours, the SVP 2 assigns an operating ratio “40”% to the PSU 8 in order to make the operating time of each PSU 8-11 non-uniform, and the PSU 9 Is assigned an operation ratio of “30”%. Further, the SVP 2 assigns the operation ratio “20”% to the PSU 10 and assigns the operation ratio “10”% to the PSU 11.

As described above, when the operating ratio of the PSUs 8 to 11 becomes longer as the operating time of the PSUs 8 to 11 increases, the SVP 2 evenly uses the PSUs 8 to 11 until the failure is likely to occur. It is possible to prevent the deterioration of ~ 11. In addition, the SVP can make the operation times of the PSUs 8 to 11 uneven after the PSUs 8 to 11 are likely to fail due to long-term operation.

Note that the SVP 2 may obtain the operation ratio by using not only the method of calculating the operation ratio allocated to each of the PSUs 8 to 11 by the above-described calculation but also, for example, using a table storing operation ratios that differ for each operation time. . Further, the SVP 2 may obtain not only the operation time but also the operation ratio using, for example, a table storing the operation ratio according to the service life of each of the PSUs 8 to 11 and the type of the manufacturer.

(2) Information Processing System 1 In the first embodiment described above, the SVP 2 is set to the information processing system 1 that executes various types of information processing. However, the embodiment is not limited to this. For example, the SVP 2 may be installed in a storage system and may control a PSU that supplies power to a storage or the like. That is, the selection process executed by the SVP 2 described above can be applied to any system.

Note that the number of PSUs 8 to 11 included in the PSU group 3, the number of SBs 16 to 19 and the IOBs 20 to 23 included in the hard resource group 4, the configuration, and the like are not limited to the above-described embodiments.

(3) Functional configuration Of the processes described above, all or part of the processes described as being automatically performed can be manually performed. Alternatively, all or part of the processing described as being performed manually can be automatically performed by a known method. In addition, the processing procedures, specific names, and information including various data and parameters shown in the document and drawings can be arbitrarily changed unless otherwise specified.

Also, each component of each illustrated apparatus is functionally conceptual and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution and integration of each device is not limited to the illustrated one. That is, all or a part of them can be configured to be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. For example, the selection process described above may be realized by a plurality of SVPs.

Furthermore, all or any part of each processing function performed in each device is realized by a CPU and a program and firmware analyzed and executed by the CPU, or is realized as hardware by wired logic. obtain.
