Description

Information processing apparatus, management apparatus, and component management method

This invention relates to management of an information processing apparatus.

In the server device, parts such as PSU (Power Supply Unit) and FAN are made redundant so that the system does not stop due to a single failure. The PSU and FAN that are redundant parts are spare parts of the operating parts as long as no failure occurs, and if one of the operating PSUs or FANs fails, the PSU that is a spare part Or FAN acts as an alternative.

Redundant parts are powered off while the server device is operating without failure. Therefore, redundant parts can be replaced even when the server device is operating. When there is one PSU that is a redundant component, only one PSU can be exchanged while the server device is operating.

As a related technique, there is known a technique for specifying a combination of power supply units that can supply a necessary amount of power with the remaining power supply units when one power supply unit fails. (For example, see Patent Document 1)
In addition, a method is known in which a number is assigned to a fan and a countermeasure for when the fan fails is stored in a memory. (For example, see Patent Document 2)

JP 2009-201244 A JP-A-6-274248

In a server device in which no failure has occurred, redundant components can be powered off. For this reason, only one component can be replaced while a redundant component is operating with one server device. For this reason, even when a plurality of components are to be replaced, replacement of components can be performed only one by one while the server device is operating. Since parts are replaced one by one, there is a problem that it takes a long time for maintenance work.

In one aspect, an object of the present invention is to shorten a maintenance work time when a plurality of parts of a server device are replaced.

The information processing apparatus includes a plurality of cooling devices, a plurality of power supply devices, a power calculation unit, an index value calculation unit, a control unit, and an output unit. The plurality of cooling devices cool information processing units that process information. The plurality of power supply devices supply power to the operating cooling device and the information processing unit. The power calculation unit calculates the amount of power supplied by the plurality of power supply devices. The index value calculation unit calculates an index value representing a cooling process for maintaining the operation of the information processing unit. The control unit stops the operating cooling device among the plurality of cooling devices as long as the cooling process represented by the index value is possible. The output unit outputs an identifier of a cooling device that is stopped among the plurality of cooling devices, and information on a power supply device that is not used for supplying the amount of supplied power.

Reduce the maintenance work time when replacing multiple parts of the server device.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating an example of a server device according to the embodiment. The server apparatus 100 includes a system board 101 (101a to 101d), a service processor (SP) 102, a PSU 103 (103a to 103e), and a FAN 104 (104a to 104j). FIG. 1 is an example, and the number of FANs is arbitrary. Each of the system boards 101 has a CPU (Central Processing Unit), a memory, an I / O port, and the like. The system boards 101 operate by being connected to each other through an interconnect such as a crossbar. The SP 102 manages hardware in the server device. The PSU 103 supplies power used for the operation of the server device. The FAN 104 cools the system board 101 and the SP 102 in order to prevent the temperature of the server device from rising.

In the example of FIG. 1, it is assumed that the PSU 103a supplies power to the system board 101a when no failure has occurred and no part replacement processing has been performed. Similarly, the PSU 103b supplies power to the system board 101b, the PSU 103c supplies power to the system board 101c, and the PSU 103d supplies power to the system board 101d. The PSU 103e is a spare for the PSU 103a to PSU 103d. When any of the PSUs 103a to PSU 103d stops operating, the PSU 103e operates as a substitute for the failed PSU.

In the example of FIG. 1, the FANs 104a to 104d cool the system board 101a and the system board 101b as one group. A plurality of FANs such as the FANs 104a to 104d are grouped and referred to as a “cooling group”. The FANs 104a to 104d belong to the cooling group 105a. In the cooling group 105a, the FAN 104d is a spare for the FANs 104a to 104c. When any of the FANs 104a to 104c stops operating, the FAN 104d operates as a substitute for the failed FAN. The FANs 104e to 104h belong to the cooling group 105b. The cooling group 105b cools the system board 101c and the system board 101d. The FAN 104h belonging to the cooling group 105b is a spare for the FAN 104e to FAN 104g. When any of the FAN 104e to FAN 104g stops operating, the FAN 104h operates as a substitute for the failed FAN. The FAN 104 i and the FAN 104 j cool the service processor 102.

If the service processor 102 detects that a part replacement process has been requested, can the service processor 102 reduce the number of PSUs 103 used to cover the power used to operate the system boards 101a-101d? Determine. If the power used for the operation of the system boards 101a to 101d can be supplied even if the number of operating PSUs 103 is reduced, the service processor 102 selects a PSU 103 that may be stopped from the operating PSUs 103. . For example, it is assumed that the PSU 103a to PSU 103d are operating and the service processor 102 determines that one PSU 103 can be stopped. Then, the service processor 102 selects the PSU 103 that may be stopped from the operating PSUs 103a to PSU 103d. For example, it is assumed that the service processor 102 stops the PSU 103a. Then, in the server device, the PSU 103a and the PSU 103e are stopped. The service processor 102 outputs the identifier of the stopped PSU 103 to the display device so that the user can recognize it. For this reason, the user can perform exchange processing of a plurality of PSUs 103 whose operations are stopped.

Although the case where the PSU 103 is exchanged has been described in the above example, the same processing can be performed for the FAN 104. In this case, the service processor 102 also determines whether the cooling can be performed to such an extent that the operation of the system boards 101a to 101d is not hindered even if the number of operations of the FAN 104 in the cooling group 105 is reduced. If it is determined that the number of FAN operations can be reduced in each cooling group, the service processor 102 selects the FAN to be stopped and outputs the identifier of the stopped FAN to the display device. Further, the parts to be replaced may be both the PSU 103 and the FAN 104. Each PSU may supply power to an arbitrary system board 101. When the server apparatus supports hot swap, the service processor 102 may output the identifier of the PSU 103 that may be stopped to the display device so that the user can recognize it. In that case, when replacing the PSU 103, the user removes the PSU 103 by hot swapping.

In this way, the service processor 102 can interrupt the operation of a plurality of components and notify the user of components that are not in operation. For this reason, in the present embodiment, even when a failure occurs or when multiple parts are to be replaced, such as preventive maintenance work in which parts are replaced with new parts before the failure occurs, A plurality of parts can be exchanged without disturbing the operation. Since a plurality of parts can be exchanged at a time, it is possible to shorten the time required for maintenance parts exchange work.

FIG. 2 is a diagram for explaining an example of a block diagram of the service processor according to the present embodiment. The service processor manages hardware in the server device. The service processor includes a power calculation unit 202, an index value calculation unit 203, a control unit 204, a storage unit 205, a power supply control unit 206, and a management unit 207. The control unit 204 includes a calculation unit 208. The management unit 207 includes an acquisition unit 209 and an output unit 210.

The management unit 207 manages information related to the display device that is input by the administrator. The acquisition unit 209 of the management unit 207 acquires information on the part to be replaced input from the administrator. The output unit 210 outputs information on replacement parts managed by the management unit 207 to the display device. The management unit 207 creates replacement part information 305 from the acquired information and stores it in the storage unit 205. The replacement part information 305 is a list having identification information indicating information of parts to be replaced. The power calculation unit 202 acquires information such as the amount of power being supplied and the maximum amount of power that can be supplied from each PSU mounted by the server device. The power calculation unit 202 uses the acquired information to calculate the power supply amount used for maintaining the operation of the server device. The power calculation unit 202 creates PSU state management information 303 from the acquired information and information such as a calculated value, and stores the PSU state management information 303 in the storage unit 205. The index value calculation unit 203 acquires information such as the FAN rotation speed and the maximum rotation speed from each FAN mounted on the server device. The index value calculation unit 203 uses the acquired information to calculate an index value that represents the cooling capacity required to maintain the operation of the server device. As the index value, for example, the total value of the rotation speeds of the FANs in each cooling group may be used. The index value calculation unit 203 creates FAN state management information 304 from information such as the acquired information and the calculated value, and stores it in the storage unit 205.

The control unit 204 extracts parts that can be replaced while the server device is operating based on the calculation results of the power calculation unit 202, the index value calculation unit 203, and the like. The control unit 204 determines whether the number of operations of the FAN 104 can be reduced while satisfying the index value calculated by the index value calculation unit 203. Note that replacement part management information 301 created by the control unit 204 is used to extract parts that can be replaced while the server device is operating. The calculation unit 208 is used to calculate various information used in the processing of the control unit 204. For example, the calculation unit 208 determines whether it is possible to change the rotation speed of the FAN by using the fluctuation amount of the power consumption accompanying the change of the rotation speed. The storage unit 205 stores replacement part management information 301, SB / SP state management information 302, PSU state management information 303, FAN state management information 304, replacement part information 305, and replacement waiting part information 306. The power supply control unit 206 controls the system board based on the information on the power supply amount acquired by the power calculation unit 202 so that the supplied power amount does not increase more than the acquired power supply amount.

FIG. 3 shows an example of the hardware configuration of the server device. The server device includes a processor 11, a memory 12, a bus 15, an external storage device 16, and a network connection device 19. Further, as an option, the server device may include an input device 13, an output device 14, and a medium driving device 17. The server device may be realized by, for example, a computer.

The processor 11 can be an arbitrary processing circuit including a central processing unit (CPU). The processor 11 operates as a power calculator 202, an index value calculator 203, a controller 204, a power controller 206, and a manager 207. The processor 11 can execute, for example, a program stored in the external storage device 16. The memory 12 operates as the storage unit 205 and holds replacement part management information 301, SB / SP state management information 302, PSU state management information 303, FAN state management information 304, replacement part information 305, and replacement waiting part information 306. . Further, the memory 12 appropriately stores data obtained by the operation of the processor 11 and data used for processing of the processor 11. The network connection device 19 is used and communicated with other devices.

The input device 13 is realized as, for example, a button, a keyboard, or a mouse, and the output device 14 is realized as a display or the like. The bus 15 connects the processor 11, the memory 12, the input device 13, the output device 14, the external storage device 16, the medium drive device 17, and the network connection device 19 so that data can be exchanged between them. The external storage device 16 stores programs, data, and the like, and provides the stored information to the processor 11 and the like as appropriate. The medium driving device 17 can output the data of the memory 12 and the external storage device 16 to the portable storage medium 18 and can read programs, data, and the like from the portable storage medium 18. Here, the portable storage medium 18 may be any portable storage medium including a floppy disk, a Magnet-Optical (MO) disk, a Compact Disc Recordable (CD-R), and a Digital Versatile Disc Recordable (DVD-R). It can be a medium.

FIG. 4 is a diagram for explaining an example of the system state of the server apparatus according to the embodiment. In FIG. 4, the same components as those in FIG. In FIG. 4, FANi and FANj belong to the cooling group 105c. The cooling group 105 c cools the service processor 102. Since the system board 101a in FIG. 4 is in operation, the power is on. In addition, the power consumption of the system board 101a is 150W. The system board 101b is powered on and has a power consumption of 130W. The system board 101c is not operating, the power is OFF, and the power consumption is 30W. The system board 101d is powered off and consumes 30W. The SP 102 is powered on and consumes 30 W. Further, the total power consumption of the FAN 104 (104a to 104j) of the server apparatus 100 of FIG. 4 is 100W. FIG. 4 is an example, and the number and state of PSU, FAN, etc. are arbitrary.

Processing of maintenance work according to the present embodiment will be described with reference to a specific example of the server device in FIG. 4 and FIGS. The processes (1) to (10) described below explain the order of the processes of the entire maintenance work according to this embodiment. The processes (1) to (10) will be described using specific numbers and examples.

(1) The administrator selects and inputs a replacement target component from the component information displayed on the display device.

FIG. 5 is a diagram for explaining a display example on the display screen according to the embodiment. The example of the display screen 401a in FIG. 5 displays information about each component such as PSU0 to PSU4 and FAN0 to FAN9 mounted on the server device. The information displayed by the display device is arbitrary identification information for identifying each component. In the example of the display screen 401a in FIG. 5, a selection box is displayed next to the identification information of each component. A state in which the selection box is black indicates that the administrator has selected the replacement box. On the other hand, a state in which the selection box is white represents that the administrator has not selected the replacement box. The administrator inputs information by selecting a part to be exchanged from the display device and pressing Apply.

In the example 401a in FIG. 5, PSU0, PSU2, FAN0, FAN1, FAN4, and FAN7 are selected by the administrator, so the selection box is black. The acquisition unit 209 acquires information input from the display device. The acquisition unit 209 acquires identification information regarding the part to be replaced. Based on the information acquired by the acquisition unit 209, the management unit 207 causes the storage unit 205 to store information regarding a component to be replaced by the administrator as replacement component information 305. When the process of the management unit 207 ends, the process (2) is executed.

(2) The power supply control unit 206 acquires the latest information on the power supply status, power consumption, and suppression status of the system board and service processor. Information about the power supply state, power consumption, and suppression state acquired by the power supply control unit 206 is shown in the SB / SP state management information 302a in FIG.

FIG. 6 is a diagram illustrating an example of SB / SP state management information according to the embodiment. The SB / SP status management information 302 includes information on the power status, power consumption, and suppression status for each system board and service processor. In the example of FIG. 6, the system board with the system board number 0 is the system board 101a. The system board of system board number 1 is the system board 101b. The system board of system board number 2 is the system board 101c. The system board of system board number 3 is the system board 101d. The component of the system board number SP is a service processor. The suppression state is information regarding whether or not the power usage limit (power capping) is set. The power controller 206 limits the amount of power used by the system board and the service processor as a power consumption limit so that the amount of power does not increase beyond the power consumption acquired by the power controller 206. Note that the suppression state ON is a state in which power usage is restricted, and the suppression state OFF is a state in which there is no power consumption limitation.

As an example, in the SB / SP status management information 302a, the power status of the

system boards

101a and 101b is ON, the power status of the

system boards

101c and 101d is OFF, and the power status of the service processor is ON. In addition, ON of a power supply state shows an operation state, and the power supply state OFF shows that the power supply is not turned on and a stop state. Since the

system boards

101a and 101b are in an operating state, the power consumption is 150 W and 130 W, which is larger than the power consumption 30 W of the

system boards

101c and 101d. The power consumption of the SP is 50W. The suppression state of the system board 101 (101a to 101d) and the service processor is OFF.

When the power control unit 206 acquires information from the system board and the service processor, the power control unit 206 limits the power consumption. The power supply control unit 206 stores the acquired information and the latest inhibition state in the storage unit 205 as SB / SP state management information 302. The information stored here is the state of the SB / SP state management information 302b. Since the SB / SP state management information 302b is in a state where power consumption is restricted, the suppression state is ON. When the process of the power control unit 206 is completed, the process (3) is executed.

(3) The power calculation unit 202 acquires the latest information on the supplied power amount and the information on the maximum supplied power amount from each PSU. The latest information on the supplied power amount and the information on the maximum supplied power amount acquired by the power calculating unit 202 are shown in the PSU state management information 303a in FIG.

FIG. 7 is a diagram illustrating an example of PSU state management information according to the embodiment. The PSU state management information 303 includes information on supply power and maximum supply power for each PSU. Further, the PSU state management information includes the total amount of power supplied (SUP_POW), the remaining power (ENG_POW), and the maximum number of PSUs that can be exchanged (MAX_PSU). PSU number 0 to PSU number 4 correspond to PSU 103a to PSU 103e. The information regarding the supplied power is the amount of power supplied from the PSU for operating the system board or the like when the power calculation unit 202 acquires the information. The maximum power supply is the maximum value of the power that can be supplied in the specifications of the PSU.

As an example, the power supply amount in the PSU state management information 303a is 150 W for PSU0 and PSU1, 70 W for PSU2 and PSU3, and 50 W for PSU4. The maximum power supply amount is all 500 W.

Next, the power calculator 202 calculates the total amount of power supplied (SUP_POW). The total amount of power supplied (SUP_POW) is the total amount of power supplied by the PSU installed in the server device. Therefore, the total amount of power supplied (SUP_POW) in the embodiment is calculated as follows.
(SUP_POW) = (150 W + 150 W + 70 W + 70 W + 50 W) = 490 W

The power calculation unit 202 causes the storage unit 205 to store the acquired information and information on the total power supply amount (SUP_POW) as PSU state management information 303. The information stored here is the state of the PSU state management information 303b. The surplus power (ENG_POW) and the maximum number of PSUs that can be exchanged (MAX_PSU) in the PSU state management information 303 will be described later.

(4) The index value calculation unit 203 acquires information on the FAN rotation speed, the maximum rotation speed, the cooling group, and the total power consumption of the FAN as information on the state of each FAN installed in the server device. The FAN rotation speed, the maximum rotation speed, and the cooling group acquired by the index value calculation unit 203 are shown in the FAN state management information 304a in FIG. 8A.

FIG. 8 is a diagram illustrating an example of FAN state management information according to the embodiment. The FAN state management information 304 includes the following information for each FAN.
FAN rotation speed at the time of information acquisition (FAN_NOR)
Further, the FAN state management information 304 classifies a plurality of FANs into cooling groups. The FAN state management information 304 includes the following information for each cooling group.
Total number of rotations of cooling group number FAN to which FAN belongs (FAN_RPM)
Number of rotations of FAN that is operating during parts replacement (FAN_NOW)
Total power consumption for each cooling group (FAN_POW)
Increased power consumption (ΔFAN_POW)
Maximum number of FANs that can be exchanged (MAX_FAN)
Note that FAN numbers 0 to 9 correspond to FANs 104a to 104j.

The FAN rotation speed (FAN_NOR) at the time of information acquisition is the FAN rotation speed when the index value calculation unit 203 acquires information. The full rotation speed of FAN is the maximum rotation speed according to the specifications of FAN. The cooling group number to which the FAN belongs is identification information of the cooling group to which the FAN belongs. The cooling group is set in advance.

As an example, the rotation speed (FAN_NOR) of FAN at the time of information acquisition of FAN0 and FAN2 is 7000 rpm. The rotation speed (FAN_NOR) of FAN at the time of information acquisition of FAN1 and FAN3 is 5000 rpm. The rotation speed (FAN_NOR) of the FAN when acquiring information of the FANs 4 to 7 is 1000 rpm. The number of rotations of FAN (FAN_NOR) at the time of information acquisition of FAN8 and FAN9 is 4800 rpm. The full rotation speed of all FANs of FAN0 to FAN9 is 12000 rpm. As the cooling group numbers to which the FAN belongs, the FAN numbers 0 to 3 (FANs 104a to 104d) belong to the cooling group 1. FAN numbers 4 to 7 (FANs 104e to 104h) belong to the cooling group 2. FAN numbers 8 to 9 (FANs 104i to 104j) belong to the cooling group 3. In the embodiment, the FAN rotation number is used as the index value for the cooling process, but any other value may be used as long as it indicates the cooling capacity.

Next, the index value calculation unit 203 calculates the total FAN rotation speed (FAN_RPM) and the total power consumption (FAN_POW) for each cooling group using the acquired values. The total FAN rotation speed (FAN_RPM) for each cooling group is the total FAN rotation speed (FAN_NOR) of each FAN belonging to the cooling group. The total power consumption (FAN_POW) for each cooling group is calculated from the acquired information on the total power consumption of the FAN and the FAN rotation speed (FAN_NOR) of each FAN.

As an example, the total FAN rotation speed (FAN_RPM) of the cooling group 1 is calculated as follows.
(7000 + 5000 + 7000 + 5000) = 24000rpm
The total FAN rotation speed (FAN_RPM) of the cooling group 2 is calculated as follows.
(1000 + 1000 + 1000 + 1000) = 4000 rpm
The total FAN rotation speed (FAN_RPM) of the cooling group 3 is calculated as follows.
(4800 + 4800) = 9600rpm

The index value calculation unit 203 calculates the total power consumption (FAN_POW) for each cooling group from the amount of power consumed by the entire FAN mounted on the server device. In the example of FIG. 4, the amount of power consumed by the entire FAN mounted on the server device is 100W. The index value calculation unit 203 calculates a coefficient indicated by ΔP from the overall power consumption of the FAN. ΔP is a coefficient used for calculating the power consumption corresponding to the rotation speed of the FAN used as the index value. In the formula, (FAN_NOR) of FAN0 is abbreviated as NOR ₀ . The subscript number following NOR indicates the FAN number.
100W = ΔP × (NOR ₀ ^ 3 + NOR ₁ ^ 3 + NOR ₂ ^ 3 + NOR ₃ ^ 3 + NOR ₄ ^ 3 + NOR ₅ ^ 3 + NOR ₆ ^ 3 + NOR ₇ ^ 3 + NOR ₈ ^ 3 + NOR ₉ ^ 3)

The value of ΔP is calculated by the above formula, and the index value calculation unit 203 calculates the total power consumption (FAN_POW) for each cooling group.

As an example, the total power consumption (FAN_POW) of the cooling group 1 is as follows.
ΔP × (NOR ₀ ^ 3 + NOR ₁ ^ 3 + NOR ₂ ^ 3 + NOR ₃ ^ 3) = 80 W
The total power consumption (FAN_POW) of the cooling group 2 is as follows.
ΔP × (NOR ₄ ^ 3 + NOR ₅ ^ 3 + NOR ₆ ^ 3 + NOR ₇ ^ 3) = 1 W
The total power consumption (FAN_POW) of the cooling group 3 is as follows.
ΔP × (NOR ₈ ^ 3 + NOR ₉ ^ 3) = 19 W

The index value calculation unit 203 causes the storage unit 205 to store the acquired value, the calculated total FAN rotation speed (FAN_RPM) for each cooling group, and the total power consumption (FAN_POW) for each cooling group. The information stored here is the state of the FAN state management information 304b in FIG. 8A. Note that the increased power consumption (ΔFAN_POW), the maximum number of FANs that can be replaced (MAX_FAN), and the number of FAN rotations during component replacement (FAN_NOW) in the FAN state management information 304 will be described later.

Note that the processes (3) and (4) may be executed in parallel. The process (4) may be executed before the process (3).

<Process for determining exchangeable PSU>
(5-1) The control unit 204 creates replacement part management information 301 based on replacement part information 305 that is a list of parts to be replaced by the administrator. The control unit 204 sets the instruction waiting category of the replacement part management information 301 corresponding to the part that the administrator wants to replace to “ON”. (5-1) The state after processing is shown in the replacement part management information 301a in FIG. 9A.

FIG. 9 is a diagram illustrating an example of replacement part management information according to the embodiment. The replacement part management information 301 has categories of waiting for instructions, replacement candidates, waiting for replacement, and replacement for each PSU and FAN. The category waiting for instruction is set to ON for the part requested to be replaced by the administrator. The instruction waiting category is a category used for determining whether or not it is waiting for an instruction from the control unit 204. The exchange candidate is a category used for determining whether or not exchange is possible in mid-process. Waiting for replacement is a state in which it is determined that replacement is possible in the process, and waiting for replacement by the administrator. Replaced is a category set after the administrator replaces a part.

As an example, the control unit 204 sets “ON” in the instruction waiting category corresponding to PSU0, PSU2, FAN0, FAN1, FAN4, and FAN7 requested by the administrator to be replaced on the display screen 401a of FIG. The information set here is the state of the replacement part management information 301a in FIG. 9A. In each category of FIG. 9, although expressed as “ON” and “OFF”, the embodiment is not limited.

(5-2) The calculation unit 208 of the control unit 204 calculates the maximum number of PSUs that can be exchanged (MAX_PSU). A calculation formula of (MAX_PSU) and a specific example thereof are shown below. In the following expression, the total number of PSUs mounted on the server is described as A, and the maximum power supply amount of the PSU is described as B.
(MAX_PSU) = A− (Supply power amount (SUP_POW) ÷ B)

Therefore, (MAX_PSU) can be calculated using the example of the system of FIG. 4 and the example of the PSU state management information 303b of FIG.
(MAX_PSU) = 5− (490 ÷ 500) = 4

The control unit 204 stores information on the maximum number of exchangeable PSUs (MAX_PSU), which is a calculation result, in the PSU state management information 303. As an example, when 4 that is the value of (MAX_PSU) is stored in the PSU state management information 303 in FIG. 7, the PSU state management information 303b in FIG. 7 is updated to the PSU state management information 303c.

(5-3) The control unit 204 sets the number of PSUs (REQ_PSU) in which the instruction waiting category in the replacement part management information 301 (301a) in FIG. MAX_PSU).

If (REQ_PSU) is larger than (MAX_PSU), the number of parts to be replaced exceeds the number of parts that can be replaced. The control unit 204 sets the value of the maximum number of exchangeable PSUs (MAX_PSU) as the number of exchanged PSUs (CHG_PSU). On the other hand, when (MAX_PSU) is larger than (REQ_PSU), the number of replaceable parts exceeds the number of parts to be replaced. The control unit 204 sets the value of (REQ_PSU) as the number of PSUs to be exchanged (CHG_PSU).

In the example of the PSU state management information 303c in FIG. 7, the maximum number of PSUs that can be exchanged (MAX_PSU) is four. The number (REQ_PSU) of PSUs in which the instruction waiting category in the replacement part management information 301 (301a) in FIG. Therefore, the number of PSUs to be exchanged (CHG_PSU) is 2.

(5-4) The calculation unit 208 of the control unit 204 calculates the remaining power amount (ENG_POW) of the server device. A specific example using the calculation formula of (ENG_POW) and the PSU state management information 303b of FIG. 7 is shown below. In the following equation, the number of PSUs installed in the server apparatus is denoted as A, the number of PSUs to be exchanged (CHG_PSU) as B, and the number of non-exchanged PSUs as C. Further, in the following expression, the maximum power supply amount (MAX_POW) of the PSU is described as D, and the power supply amount (SUP_POW) is described as E.
Number of PSUs not exchanged C = AB
(ENG_POW) = D × CE

In the system example of FIG. 4, the server apparatus has five PSUs. The number of PSUs to be exchanged (CHG_PSU) obtained in (5-3) is two. Therefore, the number of PSUs that are not exchanged is three. The maximum power supply amount (MAX_POW) of the PSU in the PSU state management information 303b in FIG. 7 is 500W. The power supply amount (SUP_POW) is 490W. (ENG_POW) in the embodiment is as follows.
500W × 3-490W = 1010W

The control unit 204 stores information on the remaining power amount (ENG_POW) of the server device, which is the calculation result, in the PSU state management information 303. As an example, when 1010W which is the value of (ENG_POW) is stored in the PSU state management information 303, the PSU state management information 303c in FIG. 7 is updated to the PSU state management information 303d.

The remaining power amount of the server device is used to determine whether or not the increased power amount can be secured by substituting the FAN cooling process described later.

(5-5) The control unit 204 selects the number of replaceable PSUs (CHG_PSUs) from among the PSUs whose instruction waiting category in the replacement part management information 301 (301a) in FIG. 9A is “ON”. To do. The control unit 204 sets the selected PSU instruction waiting category to “OFF” and sets the selected PSU replacement waiting category to “ON”.

If all of the PSUs whose instruction waiting category is “ON” cannot be selected as exchangeable PSUs, priority may be given to selecting PSUs with less power supply.

As an example, the number of PSUs to be exchanged (CHG_PSU) obtained in (5-3) is two. In the replacement part management information 301a of FIG. 9A, there are two PSUs whose instruction waiting category is “ON”. Therefore, the control unit 204 sets both the PSU 0 and PSU 2 to “OFF” for the PSU instruction waiting category and “ON” for the replacement waiting category. As a result of the setting, the replacement part management information 301 becomes the state of the replacement part management information 301b in FIG. 9A.

The processes (5-1) to (5-5) may be performed after the process (3). Therefore, it may be executed in parallel with the process (4).

<Process for determining exchangeable FAN>
(6-1) The calculation unit 208 of the control unit 204 calculates the maximum number of FANs that can be exchanged (MAX_FAN). An example using the calculation formula of the maximum number of FANs that can be exchanged (MAX_FAN) and the FAN state management information 304 (304b) of FIG. 8A is shown below. In the following equation, the total number of FANs in the cooling group is described as A, the total number of FAN rotations (FAN_RPM) as B, and the maximum number of FAN rotations as C.
(MAX_FAN) = A− (B ÷ C)

The maximum number of FANs that can be exchanged in the cooling group 1 (MAX_FAN) is calculated as follows.
4-ceil (24000rpm ÷ 12000rpm) = 2
The maximum number of FANs that can be exchanged in the cooling group 2 (MAX_FAN) is calculated as follows.
4-ceil (4000rpm / 12000rpm) = 3
The maximum number of FANs that can be replaced in the cooling group 3 (MAX_FAN) is calculated as follows.
2-ceil (9600rpm ÷ 12000rpm) = 1

The control unit 204 stores information on the maximum number of FANs that can be exchanged (MAX_FAN), which is a calculation result, in the FAN state management information 304. As an example, when the value of (MAX_FAN) is stored in the FAN state management information 304, the FAN state management information 304b in FIG. 8 is updated as the FAN state management information 304c in FIG. 8B.

(6-2) For each cooling group, the calculation unit 208 of the control unit 204 sets the number of FANs for which the instruction waiting category is set to “ON” (REQ_FAN) and the maximum number of FANs that can be replaced (MAX_FAN). Compare

As an example, the calculation unit 208 may replace the number of FANs (REQ_FAN) in which the instruction waiting category of the replacement part management information 301b in FIG. 9A is set to “ON” and the FAN state management information 304c in FIG. Is compared with the maximum number (MAX_FAN). In the example of the replacement part management information 301b in FIG. 9A, the (REQ_FAN) of the cooling group 1 is two, and the maximum number of FANs (MAX_FAN) that can be replaced in the FAN state management information 304c in FIG. 8B is two. . There are two (REQ_FAN) in the cooling group 2 and three (MAX_FAN). The cooling group 3 has (REQ_FAN) of 0 and (MAX_FAN) of 1. Therefore, (REQ_FAN) is smaller than (MAX_FAN) in all the cooling groups.

(6-2-1) When (REQ_FAN) is smaller than (MAX_FAN), the calculation unit 208 calculates the rotation number (FAN_NOW) of the FAN that is operating during component replacement for each cooling group as Calculate using. (FAN_NOW) is the number of rotations of the FAN that is operating during component replacement. In the following equation, the total number of FAN rotations (FAN_RPM) is denoted as A, the total number of FANs as B, and the number of FANs (REQ_FAN) whose instruction waiting category is set to “ON” as C.
(FAN_NOW) = A ÷ (BC)

A specific value is calculated using the example of the system in FIG. 4 and the FAN state management information 304c in FIG. 8B. Further, referring to the replacement part management information 301b in FIG. 9A, there are two (REQ_FAN) for the cooling group 1, two (REQ_FAN) for the cooling group 2, and (REQ_FAN) for the cooling group 3. , 0.

(FAN_NOW) of the cooling group 1 is calculated as follows.
24000 rpm / (4-2) = 12000 rpm
(FAN_NOW) of the cooling group 2 is calculated as follows.
4000 rpm / (4-2) = 2000 rpm
(FAN_NOW) of the cooling group 3 is calculated as follows.
9600rpm ÷ (2-0) = 4800rpm

The control unit 204 stores, in the FAN state management information 304, information on the rotation speed (FAN_NOW) of the FAN that is operating during component replacement, which is a calculation result. As an example, when the value of (FAN_NOW) is stored in the FAN state management information 304, the FAN state management information 304c in FIG. 8B is updated like the FAN state management information 304d in FIG. 8B.

The control unit 204 turns “OFF” the category in which the FAN instruction waiting category of the replacement part management information 301 (301b) in FIG. 9A is “ON”, and sets the category of replacement candidates of the same FAN to “ON”. Set. As a result of the setting, the replacement part management information 301b in FIG. 9A is updated like the replacement part management information 301c in FIG. 9B.

(6-2-2) When (REQ_FAN) is larger than (MAX_FAN), the calculation unit 208 calculates the rotation speed (FAN_NOW) of the FAN that is operating during component replacement for each cooling group as Calculate using. In the following equation, the total number of FAN rotations (FAN_RPM) is denoted as A, the total number of FANs as B, and the maximum number of FANs that can be exchanged (MAX_FAN) as C.
(FAN_NOW) = A ÷ (BC)

The control unit 204 stores, in the FAN state management information 304, information on the rotation speed (FAN_NOW) of the FAN that is operating during component replacement, which is a calculation result.

Next, the control unit 204 selects the maximum number of FANs that can be exchanged (MAX_FAN) from among the FANs whose instruction waiting category in the replacement part management information 301 (301b) in FIG. 9A is “ON”. . The control unit 204 sets the category of the selected FAN waiting for instruction to “OFF”, and sets the category of the selected FAN waiting for replacement to “ON”.

(6-3) The calculation unit 208 calculates the FAN increase power consumption (ΔFAN_POW) predicted by increasing the rotation speed of the FAN that is not the replacement target in the cooling group. The reason why the rotation speed of the FAN that is not the replacement target is increased in the cooling group is to maintain the cooling capacity used for maintaining the operation of the server apparatus. Therefore, the control unit 204 substitutes the cooling capacity for the replacement target FAN with the FAN that is not the replacement target.

The predicted FAN increased power consumption (ΔFAN_POW) is obtained by the following calculation formula, and an example using the FAN state management information 304d of FIG. 8B is also shown. Note that ΔP used in the equation is a constant used for calculating the amount of power corresponding to the rotation speed of the FAN, and the same coefficient as that used in (4) is used. In the following equation, the FAN rotation speed (FAN_NOR) at the time of collecting information to be replaced is described as A, the FAN rotation speed (FAN_NOW) operating during the parts replacement is described as B, and the power consumption (FAN_POW) is described as C. .
(ΔFAN_POW) = ΔP × (A ^ 3 + B ^ 3) −C

A specific example using the example of the FAN state management information 304d in FIG. 8B is shown below.

(ΔFAN_POW) of the cooling group 1 is calculated as follows.
(7000rpm ^ 3 + 5000rpm ^ 3 + 12000rpm ^ 3 + 12000rpm ^ 3) -80W = 258W
(ΔFAN_POW) of the cooling group 2 is calculated as follows.
ΔP × (1000 rpm ^ 3 + 1000 rpm ^ 3 + 2000 rpm ^ 3 + 2000 rpm ^ 3) -1W = 15W
(ΔFAN_POW) of the cooling group 3 is calculated as follows.
ΔP × (4800rpm ^ 3 + 2400rpm ^ 3) -19W = 57W

The control unit 204 stores the value of the increased power consumption (ΔFAN_POW) for each cooling group, which is the calculation result, in the FAN state management information 304. As an example, when the value of (ΔFAN_POW) is stored in the FAN state management information 304, the FAN state management information 304d in FIG. 8B is updated as the FAN state management information 304e in FIG. 8C.

(6-4) The control unit 204 exceeds the remaining power amount (ENG_POW) of the server device in the PSU state management information 303 in FIG. 7 in order of increasing power consumption (ΔFAN_POW) in the FAN state management information 304 in FIG. Select the cooling group to be replaced, as far as possible.

(6-4-1) For the FAN selected as the cooling group to be replaced, the control unit 204 sets the replacement candidate category “ON” in the replacement part management information 301c of FIG. And set the waiting category to “ON”.

In the example of the FAN state management information 304e in FIG. 8C, the cooling groups are selected in the order of the cooling group 2, the cooling group 3, and the cooling group 1 in which (ΔFAN_POW) is small. The total of (ΔFAN_POW) of the cooling groups 1 to 3 is 330 W, and (ENG_POW) does not exceed 510 W. Therefore, the cooling groups 1 to 3 are all selected as the cooling group to be replaced. The control unit 204 sets the FAN replacement candidate category in the replacement part management information 301 to “ON”, and the FAN selected as the cooling group to be replaced sets the replacement candidate category to “OFF” and sets the category waiting for replacement. Set to “ON”. As a result of the setting, the replacement part management information 301c in FIG. 9B is updated like the replacement part management information 301d in FIG. 9B.

(6-4-2) For the FAN that is not selected as the cooling group to be replaced, the control unit 204 sets the replacement candidate category “ON” as the replacement candidate category of the replacement part management information 301c in FIG. Set to “OFF” and set the waiting category to “ON”.

Separately from the embodiments described so far, as an example, the case where the cooling group 1 is not selected as the cooling group to be replaced is shown in the replacement part management information 301e of FIG. 9C. In the case of the replacement part management information 301e, the control unit 204 sets the replacement candidate category of the replacement part management information 301 to “ON” and sets the replacement candidate category to “OFF” for the FANs of the

cooling groups

2 and 3. Set the waiting category to “ON”. On the other hand, the control unit 204 sets the FAN replacement candidate category in the replacement part management information 301 to “ON”, and the cooling group 1 FAN sets the replacement candidate category to “OFF” and the instruction waiting category to “ON”. Set to. With this process, the FAN belonging to the cooling group 1 is excluded from the first part replacement target.

(6-5) The control unit 204 stores the PSU number and FAN number whose replacement waiting category in the replacement part management information 301 (301d) in FIG. 9B is “ON” in the replacement waiting part information 306. The replacement waiting part information 306 may store identification information indicating PSU or FAN.

9C, information regarding PSU0, PSU2, FAN0, FAN1, FAN4, and FAN7 is stored in the replacement waiting part information 306.

The process (6) is performed after the process (4). The process (6) may be executed in parallel with the process (3). The process (6-4) is executed after the process (5-4). The process (6-5) is executed after the processes (5) and (6-4) are completed.

(7) The control unit 204 operates a FAN that is operating during component replacement for a FAN that is not a replacement target in which the FAN replacement wait category in the replacement component management information 301d in FIG. 9C is set to “ON”. The rotation speed (FAN_NOW) is set. By increasing the FAN rotation speed of the FAN that is not the replacement target, it becomes possible to replace the parts.

(8) The output unit 210 of the management unit 207 outputs the parts of the server device corresponding to the PSU number and FAN number stored in the replacement-pending part information 306 to the display device as parts that can be replaced.

As an example, as shown in the display screen 401b of FIG. 5, “waiting for replacement” may be displayed to the right of the various parts selected by the administrator. The display means is not limited to this as long as it can display that the parts can be replaced.

The administrator replaces components mounted on the server device according to the display on the display device. When the replacement operation is completed, the administrator removes the check from the selected selection box and presses Apply. As a result, the administrator notifies that the replacement work has been completed. The display screen is an example, and does not limit operation means and display contents performed by the administrator.

(9) The control unit 204 performs post-processing of the replacement work. The control unit 204 operates the FAN exchanged in (8), and returns it to the FAN rotation speed (FAN_NOR) increased in (7). The replacement waiting category of the PSU and FAN whose replacement waiting category in the replacement part management information 301 is “ON” is set to “OFF”, and the replacement category is set to “ON”.

As an example, parts whose replacement category is “ON” in the replacement part management information 301d in FIG. 9B are PSU0, PSU2, FAN0, FAN1, FAN4, and FAN7. Since these parts have been exchanged by the administrator, the exchanged category is set to “ON”, and the state of the replacement parts management information 301f in FIG. 9C is entered.

The control unit 204 repeats the processing from (5-1) until there is no part in which “ON” is set in the instruction waiting category in the replacement part management information 301. For example, when the process (9) is performed based on the replacement part management information 301e in FIG. 9C, the state becomes the replacement part management information 301g in FIG. 9D. Then, since FAN0 and FAN1 remain in the “ON” state in the instruction waiting category, the processing is repeated from (5-1).

(10) The power supply control unit 206 sets the suppression state set in the SB / SP state management information 302 to “OFF”, and releases the power consumption limit.

By performing the processing from (1) to (10), even if there is only one spare part mounted on the server device, the replaceable part can be determined by the service processor determination. . By exchanging a plurality of parts, it is possible to shorten the time required for maintenance parts exchange work. 4 to 9, for example, up to four PSUs can be exchanged, and in the cooling group 1, up to two FANs can be exchanged. In the case where one spare part is mounted on the server device, the efficiency of the maintenance work can be improved compared to the replacement work in which the parts are replaced one by one. The processes (1) to (10) are performed by the service processor.

Note that the embodiment is not limited to the above, and can be variously modified. Further, specific numerical values given as examples do not limit the present embodiment at all.

FIG. 10 is a flowchart for explaining an example of component replacement processing according to the embodiment. The power calculation unit acquires information related to the power consumption state of the system from the PSU mounted on the server device (step S101). The index value calculation unit acquires information related to the cooling state of the system from the FAN installed in the server device (step S102).

The calculation unit of the control unit calculates the minimum number of PSUs that can supply the power consumption used for maintaining the operation of the server device, and obtains a replaceable PSU (step S103). The calculation unit of the control unit calculates the maximum number of PSUs that can be exchanged (step S104). The calculation unit of the control unit calculates the remaining power amount (ENG_POW) of the server device (step S105). The control unit extracts PSUs corresponding to the maximum number of replaceable PSUs from the PSUs designated by the display device (step S106).

The calculation unit of the control unit calculates the minimum number of FANs that can ensure the cooling capacity used for maintaining the operation of the server device, and obtains FANs that are not used (step S107). In order to supplement the cooling capacity of the FAN to be replaced, the calculation unit of the control unit obtains increased power consumption by increasing the number of rotations of the FAN that is not the replacement target (Step S108). The control unit determines whether the remaining power amount is sufficient even if the number of rotations of the FAN that is not the replacement target is increased (step S109). The control unit extracts FANs corresponding to the number of FANs that can be exchanged from the FAN specified by the display device (YES in Step S110 and Step S109). The management unit displays the exchangeable PSU and FAN name on the display device (NO in step S111 and step S109). The control unit determines whether the replacement of the component is completed (step S112). When the process of S112 ends, the part replacement process by the server apparatus ends. On the other hand, if the replacement of parts has not been completed, the process is repeated from S103 (NO in step S112).

FIG. 11 (FIGS. 11A and 11B) is a flowchart for explaining an example of detailed processing for parts replacement. The management unit obtains information regarding the part to be replaced, which is input by the administrator, from the display device (step S201). The power supply control unit acquires information on the power supply status, power consumption, and suppression status of the system board and service processor, and limits the power consumption to the system board and service processor (step S202). The power calculator acquires information related to the amount of supplied power from the PSU (step S203). The index value calculation unit obtains information on the state of each FAN mounted on the server device, and calculates the power consumption for each cooling group (step S204).

The calculation unit of the control unit calculates the number of PSUs that satisfy the power consumption (step S205). The control unit compares the number of PSUs to be replaced by the administrator with the number of PSUs that can be replaced by subtracting the number of PSUs that satisfy the power consumption amount from the number of PSUs installed in the server device. It is determined whether all the PSUs to be exchanged by the person can be exchanged (step S206). The control unit sets all PSUs to be exchanged by the administrator as exchangeable PSUs (YES in steps S207 and S206). The control unit sets some of the PSUs to be exchanged by the administrator as exchangeable PSUs (NO in Step S208 and Step S206). The calculation unit of the control unit calculates the remaining power amount (ENG_POW) of the server device (step S209). The control unit sets the replaceable PSU whose instruction waiting category is “ON” in the replacement part management information to “OFF”, and sets the replaceable PSU replacement wait category to “ON” ( Step S210).

The calculation unit of the control unit calculates the number of FANs that satisfy the cooling capacity for each cooling group (step S211). The control unit compares the FAN that is to be replaced by the administrator with the number of FANs that can be replaced by excluding the number of FANs that satisfy the cooling capacity from the FAN that is mounted on the server device, and the administrator replaces the FAN. It is determined whether all target FANs can be exchanged (step S212). The control unit sets “OFF” as the instruction waiting category in the replacement part management information corresponding to all FANs to be replaced by the administrator, and sets the replacement candidate category as “ON” (step S213). , YES in step S212). The control unit sets “OFF” for the instruction waiting category in the replacement part management information corresponding to some of the FANs to be replaced by the administrator, and sets the replacement candidate category to “ON”. Set (NO in step S214 and step S212).

The calculation unit of the control unit calculates the FAN increased power consumption (ΔFAN_POW) predicted by increasing the rotation speed of the FAN that is not the replacement target in the cooling group (step S215). The control unit compares the increased power consumption amount with the surplus power amount, and determines whether the surplus power amount is larger (step S216). The control unit selects a cooling group to be exchanged (YES in steps S217 and S216). The control unit determines whether or not each FAN belongs to a cooling group to be replaced (NO in step S218 and step S216). The control unit sets the replacement candidate category of the FAN in which the replacement candidate category in the replacement part management information is “ON” to “OFF” and sets the waiting category to “ON” (step) S219, YES in step S218). The control unit sets the replacement candidate category of the FAN whose replacement candidate category in the replacement part management information is “ON” to “OFF” and sets the waiting category to “ON” (step) S220, NO in step S218).

The control unit creates replacement waiting part information based on the information of the part whose waiting category is “ON” (step S221). The calculation unit of the control unit increases the number of rotations of the FAN that is not the replacement target in the cooling group that is the target of replacement (step S222). The management unit displays the component information regarding the PSU and FAN stored in the replacement waiting component information on the display device (step S223). The control unit determines whether or not the part replacement work has been completed (step S224). Until the replacement work is completed, the process of step S224 is repeated (NO in step S224). The maintenance control unit operates the replaced FAN, and returns the rotation speed of the FAN whose rotation speed has been increased (step S225). The maintenance control unit sets the PSU and FAN waiting for replacement category in the replacement part management information “ON” to “OFF”, and sets the replaced category to “ON” (step S226). . The maintenance control unit determines whether there is no part for which “ON” is set in the instruction waiting category in the replacement part management information (step S227). If there are any parts for which “ON” is set in the instruction waiting category, the process is repeated from S205 (NO in step S227). The power supply controller cancels the power usage restriction (YES in steps S228 and S227). The server device ends the part replacement process.

Even if there is only one spare component mounted on the server device by the process at the time of replacing the component of the server device, the replaceable component can be determined by the determination of the service processor. By exchanging a plurality of parts, it is possible to shorten the time required for maintenance parts exchange work. Furthermore, when the method according to the embodiment is applied to an apparatus provided with a plurality of redundant parts, similarly, the number of parts equal to or greater than the number of redundant parts can be replaced at a time. The embodiment is not limited to the above, and can be variously modified. Further, specific numerical values given as examples do not limit the present embodiment at all.
