Management computer and management method of computer system

摘要

A management computer stores an operation requirement of a virtual machine and a scheme of a first configuration change executed by a host computer or a storage apparatus. The management computer determines whether a second configuration change configured so as to be executed automatically in the host computer or the storage apparatus is executed. If it is determined that the second configuration change is executed, the management computer predicts a performance index value concerning a prescribed performance index for the computer or the storage apparatus when executing the second configuration change. The management computer determines whether an anticipated effect value of the configuration change scheme is satisfied based on the predicted performance index value, and creates a substitution plan satisfying both an operation requirement and an anticipated effect value of the virtual machine where it is determined that the anticipated effect value is not satisfied.

主权项

1. A management computer which is coupled to a computer and a storage apparatus, the management computer comprising:
a memory configured to store a piece of first configuration information indicating plural logical storage areas provided by the storage apparatus, a piece of second configuration information stored in a first logical storage area among the plural logical storage areas and indicating an operation requirement of a prescribed object executed by the computer, and a piece of configuration change scheme information indicating a scheme of a first configuration change scheduled to be executed by the computer or the storage apparatus; and a microprocessor coupled to the memory, wherein the microprocessor is configured to: determine whether a second configuration change configured beforehand so as to be executed in accordance with a prescribed condition in the computer or the storage apparatus is executed; predict, in a case where it is determined that the second configuration change is executed, a performance index value concerning a prescribed performance index for the computer or the storage apparatus in a case of executing the second configuration change; determine whether a previously configured anticipated effect value concerning the configuration change scheme is satisfied based on the predicted performance index value; and create a substitution plan satisfying both of the operation requirement of the prescribed object and the anticipated effect value in a case where it is determined that the anticipated effect value is not satisfied.
