Description

  The present invention relates to an information processing takeover control device for controlling information takeover processing when another information processing device takes over and executes information processing that has been executed in the information processing device.

  In a system including a large number of server devices such as a blade server system, for example, a failure occurs in a plurality of server devices at almost the same timing triggered by a failure that occurs in a location that affects the operation of the plurality of server devices. There is a case. When a failure occurs in the server device, the information processing performed in the server device in which the failure has occurred is taken over by the failover process, so another server device in the standby state continues to execute the information processing. .

  In the above case, for example, when the number of server devices in a standby state that is a file over destination is less than the number of server devices in which a failure has occurred as a failover source, for all information processing stopped due to the failure, Failover cannot be performed at once. Therefore, file over processing is performed in order for a plurality of stopped information processing. In this case, if failover processing is performed without considering the priority related to information processing that has been stopped due to a failure, the information processing with lower priority performs the failover processing before the information processing with higher priority. There is a risk of being. In addition, when the system administrator sets the priority for failover processing for each information processing, the system administrator is required to have specialized knowledge and know-how, and the man-hour for managing the system by the system administrator increases. To do. Therefore, it is required to perform failover processing on a plurality of stopped information processings in an appropriate order based on the priority associated with each information processing without increasing the burden on the system administrator.

  As a technique related to the above-described processing, Patent Document 1 sets a priority related to the failover processing for each node constituting the local site, and is based on the relationship between the preset priority and the range of the failover destination. Thus, a method for performing failover processing by setting a failover destination for each node to either a remote site or a node at a local site is disclosed.

  When performing failover processing based on the priorities related to a plurality of stopped information processing, it is not sufficient to simply assign the failover destination server devices in order according to the values indicated by the priorities. This is because information processing at the failover destination is activated depending on the contention status of resources such as the authentication server or network drive even if the information processing device that is the failover destination is assigned first for information processing with high priority. This is because the timing to do is not always in the order indicated by the priority. The technique disclosed in Patent Document 1 described above does not particularly refer to a technique for solving this problem.

  A main object of the present invention is to provide an information processing takeover control device, an information processing takeover control method, and an information processing takeover control program that solve this problem.

  In the information processing takeover control device according to the present invention, one or more second information processing devices take over a plurality of information processing executed by one or more first information processing devices within a predetermined time. When executing the process in any one of the information processing apparatuses except the first information processing apparatus according to the order determined according to the value indicated by the priority given to each of the information processing, An assigning unit that assigns the devices in order, and the second information processing device that activates the execution of the information processing in accordance with an activation instruction, executes the information processing according to the order determined according to the value indicated by the priority. Starting means for controlling to start in order.

  In another aspect of achieving the above object, the information processing takeover control method according to the present invention provides one or more pieces of information processing executed by one or more first information processing apparatuses within a predetermined time. When the second information processing apparatus takes over and executes the information processing apparatus, any information processing excluding the first information processing apparatus in accordance with the order determined according to the value indicated by the priority given to each of the information processing Devices in order as the second information processing device, and the second information processing device that activates the execution of the information processing in accordance with an activation instruction, the information according to the order determined according to the value indicated by the priority The first information processing apparatus, the second information processing apparatus, or an external information processing apparatus performs control so as to sequentially start the execution of processing.

  Further, in a further aspect of achieving the above object, the design information management program according to the present invention performs a plurality of information processing operations performed by one or more first information processing apparatuses within a predetermined time. When one or more second information processing devices take over and execute, any one of the information processing devices except for the first information processing device according to the order determined according to the value indicated by the priority given to each of the information processing An assignment process that sequentially assigns information processing apparatuses as the second information processing apparatus, and a determination that is made according to a value indicated by the priority for the second information processing apparatus that starts execution of the information processing in accordance with a start instruction And starting processing for controlling the execution of the information processing to start in order according to the order in which the information processing is performed.

The information processing takeover control system 1 of this embodiment includes an information processing takeover control device 10, n (n is an integer of 3 or more) server devices 20-1 to 20-n, and a storage device 30. These apparatuses are communicably connected via a communication network (hereinafter simply referred to as “network”).

  Each of the n server apparatuses 20-1 to 20-n includes BMCs (Baseboard Management Controllers) 200-1 to n. The BMCs 200-1 to n perform overall system control related to the server apparatuses 20-1 to 20-n, respectively. When a failure occurs in the server devices 20-1 to 20-n, the BMCs 200-1 to 200-n notify the information processing takeover device 10 that the failure has occurred in the server device together with identification information for identifying the server device. . Note that the notification regarding the occurrence of a failure in the server device may be performed by a failure notification function in an OS (Operating System) operating in the logical server built in the server device, or the system monitoring provided in the server device. Sometimes modules do. In response to an instruction from the information processing takeover control apparatus 10, the BMCs 200-1 to 200-n read the logical server activation information related to the logical servers constructed in the server apparatuses 20-1 to 20-n from the storage apparatus 30, and activate the logical servers To do.

  Of the n server devices 20-1 to 20-n, (n-2) server devices 20-1 to (n-2) are logical servers 201-1 to (n-2), respectively. The information processing related to the logical servers 201-1 to (n-2) is executed. Each of the server apparatuses 20-1 to (n-2) may construct two or more logical servers, but in the present embodiment, each server apparatus constructs one logical server. The two server devices 20- (n-1) to n are in a standby state as server devices to be failed over when a failure occurs, and no logical server is constructed. There are two server apparatuses in the standby state, and there are cases where server apparatuses other than the two server apparatuses are in the standby state.

  The storage apparatus 30 includes m (m is an integer equal to or greater than (n−2)) boot disks 31-1 to 31-m. The startup disks 31-1 to 31-m are storage devices such as a magnetic disk or an electronic disk that store data through an interface such as FC (Fibre Channel) or iSCSI (Internet Small Computer System Interface). The n-2 startup disks 31-1 to (n-2) are logical server startup information 310-1 to 310-1 which are logical server images related to the logical servers 201-1 to (n-2), respectively. (N-2) is stored. Each boot disk may store two or more logical server boot information.

  The information processing takeover control system 1 may be installed in two or more sites. In this case, the storage apparatus 30 stores replicas related to the logical server activation information 310-1 to (n-2) for each site, and the BMCs 200-1 to n perform logical server activation information 310-1 to (n−). The replica according to 2) may be read and the logical servers 201-1 to (n-2) may be activated.

  The information processing takeover control device 10 includes an allocation unit 11, an activation unit 12, a priority determination unit 13, an execution status information storage unit 14, an administrator setting information storage unit 15, and a server information storage unit 16.

  The assignment unit 11, the activation unit 12, and the priority determination unit 13 may be an electronic circuit, or may be realized by a computer program and a processor that operates according to the computer program. The execution status information storage unit 14, the administrator setting information storage unit 15, and the server information storage unit 16 are a magnetic disk or an electronic memory that is access-controlled by an electronic circuit or a computer program and a processor that operates according to the computer program. Storage device.

  The server information storage unit 16 stores a logical server information table 160 and a physical server information table 161. A configuration example of the logical server information table 160 and the physical server information table 161 is shown in FIG.

  As shown in FIG. 3A, the logical server information table 160 includes identification information for identifying the logical servers 201-1 to (n-2), and server devices 20-1 to 20 as physical servers that construct the logical servers. It includes a record in which identification information for identifying (n-2) is associated with information indicating the operating state of the logical servers 201-1 to (n-2). In the example shown in FIG. 3A, the logical servers 201-1 to 20-3 are in a stopped state, and the logical servers 201-4 to (n-2) are in an operating state.

  As illustrated in FIG. 3B, the physical server information table 161 includes a record in which identification information for identifying the server apparatuses 20-1 to 20-n and information indicating the operating state of the server apparatuses 20-1 to 20-n are associated with each other. Is included. In the example illustrated in FIG. 3B, the server apparatuses 20-1 to 20-3 are in a failure state, the server apparatuses 20-4 to (n-2) are in an operating state, and the server apparatus 20- (n-1). Through n indicate that they are in a standby state.

  The values indicated by the logical server information table 160 and the physical server information table 161 are updated as needed by the information processing takeover control device 10 based on the information received from the BMCs 200-1 to n.

  The priority determination unit 13 executes the execution status information 14-1 related to the logical servers 201-1 to (n-2) based on the information indicated by the priority determination reference table 150 stored in the administrator setting information storage unit 15. To (n-2) are obtained from the logical servers 201-1 to (n-2) and the information processing takeover control apparatus 10 periodically or at a predetermined opportunity, respectively. The priority determination unit 13 stores the obtained execution status information 14-1 to (n−2) in the execution status storage unit 14.

  A configuration example of the priority determination criterion table 150 stored in the administrator setting information storage unit 15 is shown in FIG. The values in the priority determination criterion table 150 may be set by a system administrator via a management terminal device (not shown) or set according to a predetermined criterion by the information processing takeover control device 10 There is also. The values in the priority determination criterion table 150 may be fixed, or may be changed statically or dynamically.

  As shown in FIG. 4A, the priority determination criterion table 150 includes a record that associates a priority, an execution status item, and a priority determination criterion. The execution status item indicates an item related to the execution status when the logical server is executed in the server device, and there are six items in the example shown in FIG. The average processor usage rate, average memory usage rate, and average network usage rate are average usage rates in a predetermined period (for example, one day) related to each resource of the server device used by the logical server. These values indicating the average usage rate are collected by the OS operating in the logical server. The charged amount and the guaranteed amount based on SLA (Service Level Agreement) are indicated by the amount per unit time, and the value is stored in each server device or the information processing takeover control device 10. The provided service type is information for identifying a service provided by each logical server.

  The priority determination unit 13 obtains execution status information 14-1 to (n-2) related to the logical servers 201-1 to (n-2) for the execution status items indicated by the priority determination criterion table 150. A configuration example of the execution status information 14-1 is shown in FIG. The priority determination unit 13 obtains values indicated by the execution status for the six execution status items indicated by the priority determination criterion table 150. Note that the six execution status items shown in FIGS. 4A and 5 are merely examples, and may be items with different contents.

  When the priority determination unit 13 receives that a failure has occurred in the server device from a plurality of server devices within a predetermined time (for example, 10 seconds), the priority determination unit 13 determines that the failure has occurred at substantially the same timing. A value indicated by the priority associated with the logical server when the logical server constructed by the server apparatus is failed over to the server apparatus in the standby state is determined. The predetermined time described above may be a value other than 10 seconds, and may be set statically or dynamically by the system administrator or the information processing takeover control device 10.

  As shown in FIG. 3, the priority determination unit 13 determines the priority determination criteria when the logical servers 201-1 to 3 stop when the failure occurs in the server devices 20-1 to 20-3 within a predetermined time. Based on the information indicated by the table 150 and the execution status information 14-1 to 14-3, the value indicated by the priority when the logical servers 201 to 3 are subject to failover processing is determined.

  As shown in FIG. 4A, the priority determination unit 13 has the highest priority value in the priority determination reference table 150 (in this embodiment, the smaller the numerical value indicating the priority, The execution status item in the record (indicating that is high) is the average processor usage rate. For the average processor usage rate, it is confirmed that a logical server having a large value is prioritized as a priority determination criterion. The priority determination unit 13 confirms the value indicated by the execution status related to the average processor usage rate in the execution status information 14-1 to 14, and determines the value indicated by the priority related to the logical servers 201-1 to 3 from the value. Then, the priority table 130 is generated. A configuration example of the priority order table 130 is shown in FIG. The priority order table 130 illustrated in FIG. 6 indicates that failover processing is performed in the order of the logical server 201-1, the logical server 201-2, and the logical server 201-3.

  When there are logical servers having the same value indicated by the average processor usage rate for the logical servers 201-1 to 201-3, the values indicated by the priorities related to these logical servers are equal. In this case, the priority determination unit 13 refers to the priority determination reference table 150 so that the execution status item in the record having the second highest priority is the average memory usage rate, and the average memory usage rate. As for priority, it is confirmed that a logical server having a large value is given priority as a priority determination criterion. The priority determination unit 13 indicates, for logical servers having the same priority value with respect to the average processor usage rate, the priority related to the logical server from the value indicated by the execution status related to the average memory usage rate in the execution status information. The value is determined and the priority table 130 is updated.

  Regarding the logical servers 201-1 to 201-3, when there is a logical server in which both the average processor usage rate and the average memory usage rate are equal, the priority determination unit 13 determines the priority in the priority determination criterion table 150. For the average network usage rate, which is the third highest execution status item, the same processing as described above is performed, and the priority table 130 is updated. The priority determination unit 13 relates to the execution status items in the order indicated by the priorities in the priority determination criterion table 150 until the values indicated by the priorities for the logical servers 201-1 to 3 are different from each other. The same processing is repeated and the priority table 130 is updated.

  The allocating unit 11 sequentially allocates server devices to be failed over to the logical servers 201-1 to 3 based on the values indicated by the priority order table 130 and the physical server information table 161. As shown in FIG. 3B, the physical server information table 161 indicates that the two server apparatuses 20- (n-1) to n are in a standby state.

  In the priority order table 130 illustrated in FIG. 6, the allocating unit 11 has a server device 20-(n−1) as a server device that is a failover destination for the logical server 201-1 having the highest priority value. Assign. Next, the allocating unit 11 uses the server device 20-n as a server device to be a failover destination for the logical server 201-2 having the second highest priority value in the priority order table 130 illustrated in FIG. Assign. In the priority order table 130 shown in FIG. 6, the allocating unit 11 cannot allocate a failover destination server apparatus to the logical server 201-3 having the lowest priority value at this time. , Temporarily hold the assignment. In the physical server information table 161, the allocating unit 11 allocates the server device to the logical server 201-3 as a server device to be a failover destination when any server device enters a standby state. The assignment unit 11 inputs to the activation unit 12 that the server devices 20- (n-1) to n are assigned as the failover destination server devices to the logical servers 201-1 to 2.

  The activation unit 12 generates the activation time table 120 for the logical servers 201-1 and 2 based on the allocation result obtained from the allocation unit 11, the priority order table 130, and the values indicated by the activation condition table 151. A configuration example of the activation time table 120 is shown in FIG. The activation time table 120 includes a record that associates information that identifies a logical server, information that identifies a server device that configures the logical server, and a timing at which the logical server is activated.

  The activation unit 12 confirms in the activation condition table 151 shown in FIG. 4B that the number of simultaneous activations related to the logical server is 1, and the activation interval when the logical servers are activated in turn is 30 seconds. To do. Note that the values indicated by the number of logical server simultaneous activations and the activation interval in the activation condition table 151 may not be the values illustrated in FIG. The activation condition table 151 may be set by a system administrator via a management terminal device (not shown), or may be set by the information processing takeover control device 10 according to a predetermined standard. The values in the activation condition table 151 may be fixed, or may be changed statically or dynamically.

  In the priority table 130, the activation unit 12 assigns the server device 20- (n-1) as the failover destination to the logical server 201-1 having the highest priority value, and the logical server 201- A record indicating that the timing at which 1 is activated is 0 seconds later indicating that it is immediate is generated as a record in the activation time table 120. The activation unit 12 activates the logical server 201-2 by allocating the server device 20-n as the failover destination to the logical server 201-2 having the second highest priority value in the priority table 130. A record indicating that the timing to perform is 30 seconds after the logical server 201-1 is activated is generated as a record in the activation time table 120.

  The activation unit 12 first transmits an instruction to activate the logical server 201-1 to the BMC 200- (n-1) in the server device 20- (n-1) according to the value indicated by the generated activation time table 120. To do. The activation unit 12 transmits an instruction to activate the logical server 201-2 to the BMC 200-n in the server device 20-n, 30 seconds after the activation instruction to the BMC 200- (n-1).

  Next, the operation (processing) of the information processing takeover control system 1 in this embodiment will be described in detail with reference to the flowcharts of FIGS. 2A to 2C.

  The priority determination unit 13 determines that a failure has occurred in a plurality of server apparatuses 20-k (k is a plurality of integers in 1 to n) in the server apparatuses 20-1 to 20-n within a predetermined time. Received from the BMC 200-k in 20-k (step S101). The priority determination unit 13 relates to the execution status item whose value indicated by the priority in the priority determination criterion table 150 is “1”, and the value indicated by the execution status in the execution status information 14-k related to the server device 20-k. Is confirmed (step S102). The priority determination unit 13 based on the value indicated by the execution status in the execution status information 14-k and the priority determination criterion where the value indicated by the priority in the priority determination criterion table 150 is “1”. A priority table 130 is generated (step S103).

  If there is a logical server 201-k having the same priority value in the priority table 130 (Yes in step S104), the process changes the value indicated by the variable i from 2 to p (p is the priority determination criterion table 150). In step S105 to step S109, a loop process is started. When there is no logical server 201-k having the same priority value in the priority table 130 (No in step S104), the process proceeds to step S110.

  The priority determination unit 13 relates to the server device 20-k having the same value indicated by the priority in the priority table 130 with respect to the execution status item where the value indicated by the priority in the priority determination reference table 150 is “i”. The value indicated by the execution status in the execution status information 14-k is confirmed (step S106). The priority determination unit 13 based on the value indicated by the execution status in the execution status information 14-k and the priority determination criterion where the value indicated by the priority in the priority determination criterion table 150 is “i”. The priority table 130 is updated (step S107). In the priority table 130, when there is a logical server 201-k having the same priority value (Yes in step S108), if the value indicated by the variable i is not p, the process sets 1 to the value indicated by the variable i. The process returns to step S106, and if the value indicated by variable i is p, the process proceeds to S110 (step S109). If there is no logical server 201-k having the same priority value in the priority table 130 (No in step S108), the process proceeds to step S110.

  The allocating unit 11 sequentially allocates the logical servers 201-k to the server apparatuses in the standby state in the physical server information table 161 in the order indicated by the priority order table 130 (Step S110). The activation unit 12 generates the activation time table 120 based on the priority order table 130, the activation condition table 151, and the result assigned by the assignment unit 11 (step S111).

  The process enters a loop process from step S112 to step S115 while changing the value indicated by the variable j from 1 to q (q is the number of records in the activation time table 120) (step S112). The activation unit 12 transmits an activation instruction to the BMC in the server device described in the jth record in the activation time table 120 according to the activation timing in the record (step S113). The BMC in the server device reads the logical server activation information 310-k related to the logical server 201-k described in the jth record in the activation time table 120 from the activation disk 31-k, and activates the logical server 201-k. (Step S114). If the value indicated by the variable j is not q, the process adds 1 to the value indicated by the variable j and returns to step S113. If the value indicated by the variable j is q, the entire process ends (step S115). ).

  The information processing takeover control apparatus 10 according to the present embodiment can reliably restart the information processing in the order determined according to the values indicated by the priorities related to the plurality of stopped information processing. The reason is that the assignment unit 11 sequentially assigns server devices that take over and execute the information processing in accordance with the order determined by the values indicated by the priorities related to the plurality of stopped information processing determined by the priority determination unit 13. This is because the activation unit 12 causes the server device to activate execution of the information processing in order according to the order.

  When multiple server devices fail at almost the same timing, and the information processing that was executed on the failed server device is failed over, the number of server devices in the standby state to be failed over In some cases, the number of server devices is smaller than the number of server devices that have been In this case, since it is not possible to fail over all stopped information processing at once, it is necessary to perform failover processing in order from information processing with higher priority, and to resume the information processing in that order. There is.

  The information processing takeover control device 10 according to the present embodiment includes an assigning unit 11 and an activation unit 12, and the order in which server devices that are failover destinations are assigned and the order in which stopped information processing is activated relates to information processing. Failover processing is controlled so that it is in the order determined by the value indicated by the priority. The information processing with the highest priority is first assigned a server device as a failover destination and is activated first. Therefore, for example, the information processing takeover control device 10 is activated earlier than the information processing with lower priority because the information processing to which the server device that is the first failover destination is assigned is delayed due to resource contention related to the activation. Can be avoided.

  Further, the priority determination unit 13 determines a value indicated by the priority associated with each information processing based on the priority determination criterion table 150 and the execution status information stored in the execution status information storage unit 14. Therefore, the information processing takeover control device 10 can reduce the burden on the system administrator who manages the information processing takeover control system 1. The information processing takeover control apparatus 10 can also set an appropriate value for each information processing as a priority based on the execution status of each information processing.

  Further, the information shown in the priority determination criterion table 150 and the activation condition table 151 is updated to various values by the system administrator. Therefore, the information processing takeover control device 10 can perform a control related to a detailed failover process based on the intention of the system administrator.

  Note that the information processing takeover control device 10 according to the present embodiment waits for the logical server explicitly designated by the system administrator from the server device that has constructed the logical server, other than when performing failover processing. The same operation related to information processing takeover control is performed when taking over to a server device in a state. For example, when the system administrator stops the server device to maintain some of the plurality of server devices, the information processing takeover control device 10 waits for the logical server built in the server device to be maintained. The processing described above is performed when the server device in the state is handed over. In this case, the priority determination unit 13 determines the value indicated by the priority for the plurality of logical servers explicitly specified by the system administrator, and based on the result determined by the priority determination unit 13, the allocation unit 11 and The activation unit 12 performs the above-described processing.

<Modification of First Embodiment>
The information processing takeover control device 10 according to the present embodiment described above performs processing related to information processing takeover control using a priority including two indexes of importance and urgency as a modification described below. There is a case.

  A configuration example of the priority determination criterion table 150 according to this modification is shown in FIG. The priority determination criterion table 150 includes an importance determination criterion table 151 and an urgency determination criterion table 152.

  The importance is an index indicating the importance of each logical server. Generally, a logical server having a higher usage record over a long period of time has a higher importance. On the other hand, the urgency is an index indicating the urgency related to each logical server, and generally, the urgency is higher as the logical server has a higher usage record in the immediately preceding short period. Therefore, the execution status item in the importance determination criterion table 151 is an item related to a long-term usage record of six months. The execution status item in the urgency determination criterion table 152 is an item related to the usage record in the short period immediately preceding the previous 24 hours. Note that the above-mentioned periods of 6 months and 24 hours are examples, and execution status items in the importance determination criterion table 151 and the urgency determination criterion table 152 are different from 6 months and 24 hours. It may be an item related to the use record in.

  A configuration example of the priority order table 130 according to the present modification is shown in FIG. Based on the importance determination criterion table 151 and the urgency determination criterion table 152, the priority determination unit 13 determines the values indicated by the importance and the values indicated by the urgency according to the logical servers 201-1 to 201-3. , Decide each.

  The allocating unit 11 sequentially allocates failover destination server devices in the order determined by the value indicated by the importance in the priority order table 130. In the example illustrated in FIG. 9, the assignment unit 11 first assigns the server device 20-(n−1) as the failover destination server device related to the logical server 201-1 having the highest importance. Next, the assigning unit 11 assigns the server device 20-n as a failover destination server device related to the logical server 201-1 having the highest importance.

The activation unit 12 is an order determined by the value indicated by the urgency in the priority order table 130.
The logical servers 20-1 and 2 are activated in order. A configuration example of the activation time table 120 generated by the activation unit 12 is shown in FIG. In the priority table 130, the activation unit 12 assigns the server device 20-n as a failover destination to the logical server 201-2 having the highest urgency value, and activates the logical server 201-2. A record indicating that the timing is after 0 seconds indicating that the timing is immediate is generated as a record in the activation time table 120. In the priority table 130, the activation unit 12 assigns the server device 20- (n-1) as the failover destination to the logical server 201-1 having the second highest value indicated by the urgency level. -1 is generated as a record in the activation time table 120, indicating that the timing at which -1 is activated is 30 seconds after the logical server 201-2 is activated.

  The information processing takeover control device 10 according to the present modification can reliably resume the information processing in the order determined according to the values indicated by the importance and the urgency related to the plurality of stopped information processing. The reason is that the assignment unit 11 sequentially assigns the server devices that take over and execute the information processing in accordance with the order determined by the value indicated by the importance of the plurality of stopped information processings determined by the priority determination unit 13. This is because the activation unit 12 sequentially activates the execution of the information processing for the server device according to the order determined by the value indicated by the urgency level.

  For logical servers with high importance, securing a failover destination server device is the most important issue. On the other hand, for a logical server with a high degree of urgency, starting up at the earliest possible timing is the most important issue. The information processing takeover control device 10 can perform more detailed control related to failover processing by using a priority including two indexes of importance and urgency.
