COMPUTER SYSTEM AND CONTROL METHOD THEREFOR
First Claim
1. A computer system, comprising:
- a plurality of server apparatuses;
a plurality of storage apparatuses coupled, via a primary communications network, to the plurality of server apparatuses; and
a management computer coupled, via a secondary communications network, to the plurality of server apparatuses and the plurality of storage apparatuses, wherein,the management computer is configured to store a server rank which is configured for each of the plurality of server apparatuses and represents a rank of a throughput of a server apparatus, and a storage rank which is configured for each of the plurality of storage apparatuses and represents a rank of a throughput of a storage apparatus,each of the plurality of server apparatuses is configured to execute a plurality of virtual machines, store a required server rank, which is a server rank of a server apparatus allocated to each of the plurality of virtual machines, and a required storage rank, which is a storage rank of a storage apparatus allocated to each of the plurality of virtual machines, determine whether or not to migrate a virtual machine on the basis of a load on the plurality of virtual machines, select a target virtual machine from among the plurality of virtual machines on the basis of the load on the plurality of virtual machines where the migration is determined, and transmit target virtual machine information which represents a required server rank and a required storage rank for the target virtual machine to the management computer,in response to the target virtual machine information, the management computer is configured to select a server apparatus having a server rank equal to the required server rank of the target virtual machine, as a destination server apparatus, from among the plurality of server apparatuses, select a storage apparatus having a storage rank equal to the required storage rank of the target virtual machine, as a destination storage apparatus, from among the plurality of storage apparatuses, and transmit destination information which represents the destination server apparatus and destination storage apparatus, to a target server apparatus that executes the target virtual machine, andthe target server apparatus is configured to migrate the target virtual machine to the destination server apparatus and the destination storage apparatus on the basis of the destination information.

Abstract
The performance of a virtual machine is maintained, by migrating an appropriate target virtual machine for migration to an appropriate destination resource, in response to a load on the virtual machine.
A management computer stores a server rank which represents a rank of a throughput of a server apparatus, and a storage rank which represents a rank of a throughput of a storage apparatus. Each of a plurality of server apparatuses executes a plurality of virtual machines, and stores a required server rank and a required storage rank. If it is determined that a virtual machine should be migrated on the basis of the load on the plurality of virtual machines, the management computer selects a server apparatus having a server rank equal to the required server rank as a destination server apparatus, and selects a storage apparatus having a storage rank equal to the required storage rank as a destination storage apparatus.
