Server system, computer system, method for managing server system, and computer-readable storage medium

A method of managing a server system including at least one current server processing an operation, at least one backup server prepared to take over the operation of the current server when the current server fails, and a local management computer that monitors the current server and the backup server and that controls server switching,

• the local management computer including a processor that executes a process of allocating the backup server as a take-over destination for the operation of the current server, and a memory that stores at least hardware configuration matching policy information indicating a hardware configuration condition enabling a server take-over,
• the managing method comprising:
• a step of the processor acquiring the hardware configuration information from each of the current server and the backup server;
• a step of the processor making a hardware configuration comparison based on the acquired hardware configuration information with respect to each combination of the current server and the backup server, and, by referring to the hardware configuration matching policy information read from the memory, determining the presence or absence of hardware configuration concealment and the possibility of a take-over with respect to each combination of the current server and the backup server;
• a step of the processor calculating a configuration matching rate indicating a ratio of hardware configuration matching with respect to each combination of the current server and the backup server;
• and
• a process of the processor allocating the backup server as a take-over destination of the current server with respect to each combination of the current server and the backup server, on the basis of information about the presence or absence of hardware configuration concealment, information about the possibility of a take-over, and information about the configuration matching rate.

A computer-readable storage medium having stored therein a program for causing a processor of a local management computer in a server system, which includes at least one current server processing an operation, at least one backup server prepared to take over the operation of the current server when the current server fails, and the local management computer that monitors the current server and the backup server and controls server switching, to execute a process of allocating the backup server as a take-over destination for the operation of the current server,

• wherein the program includes a program code for causing the processor to execute:
• a process of acquiring hardware configuration information from each of the current server and the backup server;
• a process of making a hardware configuration comparison based on the acquired hardware configuration information with respect to each combination of the current server and the backup server, and, by referring to hardware configuration matching policy information read from a memory storing at least hardware configuration matching policy information indicating a hardware configuration condition enabling a server take-over, determining, with respect to each combination of the current server and the backup server, the presence or absence of hardware configuration concealment and the possibility of a take-over;
• a process of calculating a configuration matching rate indicating a ratio of hardware configuration matching with respect to each combination of the current server and the backup server;
• and
• a process of allocating the backup server as the take-over destination of the current server on the basis of information about the presence or absence of hardware configuration concealment, information about the possibility of a take-over, and information about the configuration matching rate with respect to each combination of the current server and the backup server.
