摘要： When a primary server executing a task fails in a computer system where a plurality of servers are connected to an external disk device via a network and the servers boot an operation system from the external disk device, task processing is taken over from the primary server to a server that is not executing a task in accordance with the following method. The method for taking over a task includes the steps of detecting that the primary server fails; searching the computer system for a server that has the same hardware configuration as that of the primary server and that is not running a task; enabling the server, searched for as a result of the search, to access the external disk device; and booting the server from the external disk device.

摘要： In a computing system where multiple servers are connected through a network and one or more jobs are run, a power reduction facility of a supervisory server relocates jobs according to predetermined conditions, thereby reducing the amount of power consumed by the computing system. For relocating the jobs, the power reduction facility obtains server-related information such as the power properties of the servers constituting the computing system and job-related information such as performance requirements for the jobs which are run in the computing system, and searches for one or more jobs to be relocated and destination servers, based on these server-related information and job-related information, to the extent that the performance requirements for each job are fulfilled. Based on the search results, the jobs are relocated to the destination servers, and servers on which no job is running, in consequence of the relocation, are powered off.
