Abstract
The management computer stores a configuration information of a storage, a configuration information of a host computer and a VM, an information on a service level of the VM, and a performance information of a storage subsystem and a network. If an access path that the host computer uses to access a volume is changed in response to a change of storage configuration, an I/O performance of the VM operating in the host computer may be changed. If the change of state of the storage is detected, the management computer calculates a change of state of whether a service level defined for the VM is satisfied, and selects an appropriate host computer in which the VM should be operated.
Claims15
A management computer for managing a computer system configured of a plurality of host computers and a storage system having one or more storage subsystems connected via a network;
- the storage system comprising a volume where a plurality of access paths from the host computers are provided;
- the management computer managing a configuration information of the volume and the host computers, a performance information of the computer system, and a requested service level of an object executed in the host computers, wherein
- if the management computer detects that there has been a change in a configuration of the storage system, the management computer
- calculates a service level capable of being provided when the object is executed in each of the plurality of host computers based on the configuration information and the performance information, and
- based on the calculated result, selects the host computer capable of satisfying the requested service level if the object is executed.
A method for managing a computer system configured of a plurality of host computers and a storage system having one or more storage subsystems connected via a network;
- the storage system comprising a volume where a plurality of access paths from the host computers are provided;
- a management computer managing the computer system being a computer managing a configuration information of the volume and the host computers, a performance information of the computer system, and a requested service level of an object executed in the host computers,
- the method executed by the management computer comprising:
- detecting that there has been a change in a configuration of the storage system,
- calculating a service level capable of being provided when the object is executed in each of the plurality of host computers, and
- selecting the host computer capable of satisfying the requested service level when the object is executed based on the calculated result.
