Abstract

A storage management server includes a memory storing management information and a management program and a processor executing the management program with reference to the management information, and manages a storage resource allocated to a server resource. The management information includes group mapping information for converting a first parameter of the server resource into a second parameter of the storage resource. The processor receives an operation on the server resource and the first parameter and converts the operation on the server resource into an operation on the storage resource based on preset information. The processor converts the first parameter of the server resource into the second parameter of the storage resource with reference to the group mapping information, specifies the storage resource included in the second parameter, and gives an instruction to operate the storage resource.

First claim

The invention claimed is:

1. A storage management server comprising a memory storing management information and a management program and a processor executing the management program with reference to the management information, wherein the storage management server manages a storage resource allocated to a server resource, wherein
the management information includes group mapping information for converting a first parameter of the server resource into a second parameter of the storage resource in association with the first parameter for specifying the server resource and the second parameter for specifying the storage resource,
the processor receives an operation on the server resource and the first parameter and converts the operation on the server resource into an operation on the storage resource based on preset information,
the processor converts the first parameter of the server resource into the second parameter of the storage resource with reference to the group mapping information, specifies the storage resource included in the second parameter, and gives an instruction to operate the storage resource,
the first parameter includes an identifier of a group of virtual machines,
the identifier of the group of the virtual machines is associated with an identifier of the one or more virtual machines,
the second parameter includes an identifier of a group of volumes allocated to the group of the virtual machines,
the identifier of the group of the volumes is associated with the identifier of the one or more volumes, and
the group mapping information defines a relation between the first parameter and the second parameter.

2. The storage management server according to claim 1 , wherein
the storage management server includes a first storage management server of a current use system and a second storage management server of a standby system, and
when the first storage management server receives the first parameter of the server resource and addition of a virtual machine as the operation on the server resource,
the first storage management server converts the operation of adding the virtual machine to the server resource into an operation of adding a volume to the storage resource based on the preset information, and
the first storage management server converts the first parameter into the second parameter based on the group mapping information, specifies a specified storage resource corresponding to the second parameter, gives an instruction to add the volume to the specified storage resource, specifies the second parameter of the standby system corresponding to the second parameter of the current use system based on preset pair information, and transmits the specified second parameter of the standby system and an instruction to add the volume to the second storage management server.

3. The storage management server according to claim 2 , wherein
when the second storage management server receives the second parameter and the instruction to add the volume from the first storage management server, the second storage management server specifies the storage resource corresponding to the second parameter and gives an instruction to add the volume to the specified storage resource.

4. The storage management server according to claim 1 , wherein
the storage management server includes a first storage management server of a current use system and a second storage management server of a standby system, and
when the second storage management server receives the first parameter of the server resource and failover as an operation on the server resource,
the second storage management server converts the operation on the server resource into failover of a volume as the operation on the storage resource, and
the second storage management server converts the first parameter into the second parameter based on the group mapping information, specifies the second parameter of the current use system corresponding to the second parameter of the standby system based on preset pair information, and transmits the specified second parameter of the current use system and an instruction to divide pairing with the specified second parameter of the current use system to the first storage management server.

5. A method of controlling a storage management server including a processor and a memory, the method comprising:
a first step of setting group mapping information for mutually converting a first parameter of a server resource and a second parameter of a storage resource in association with the first parameter allocated to a group of server resources and a second identifier allocated to a group of storage resources by the storage management server;
a second step of receiving an operation on the server resource and the first parameter by the storage management server;
a third step of converting the first parameter of the server resource into the second parameter of the storage resource with reference to the group mapping information by the storage management server; and
a fourth step of specifying the storage resource included in the converted second parameter and giving the instruction of the operation by the storage management server, wherein
the first parameter includes an identifier of a group of virtual machines,
the identifier of the group of the virtual machines is associated with an identifier of the one or more virtual machines,
the second parameter includes an identifier of a group of volumes allocated to the group of the virtual machines,
the identifier of the group of the volumes is associated with the identifier of the one or more volumes, and
the group mapping information defines a relation between the first parameter and the second parameter.

6. The method of controlling the storage management server according to claim 5 , wherein
the storage management server includes a first storage management server of a current use system and a second storage management server of a standby system, and
in the second step, the first storage management server receives the first parameter of the server resource and addition of a volume as the operation on the server resource,
in the third step, the first storage management server converts the first parameter into the second parameter based on the group mapping information, and
in the fourth step, the first storage management server specifies a specified storage resource corresponding to the second parameter, gives an instruction to add the volume to the specified storage resource, specifies the second parameter of the standby system corresponding to the second parameter of the current use system based on preset pair information, and transmits the specified second parameter of the standby system and an instruction to add the volume to the second storage management server.

7. The method of controlling the storage management server according to claim 6 , further comprising:
a fifth step of receiving the second parameter and the instruction to add the volume from the first storage management server by the second storage management server; and
a sixth step of specifying the storage resource corresponding to the second parameter and giving an instruction to add the volume to the specified storage resource by the second storage management server.

8. The method of controlling the storage management server according to claim 5 , wherein
the storage management server includes a first storage management server of a current use system and a second storage management server of a standby system, and
in the second step, the second storage management server receives the first parameter of the server resource and failover as an operation on the server resource,
in the third step, the second storage management server
