Abstract
A policy determining unit determines an allocation method for blocks on the basis of information on a hierarchical policy stored in a policy management table and information on a volume stored in a volume management table. Then, on the basis of the determination result performed by the policy determining unit, a first allocating unit performs allocation on the basis of the specified capacity and a second allocating unit performs allocation on the basis of the specified percentage for each volume.
Claims8
A storage system comprising:
- an allocating unit that sequentially allocates, by giving priority to a high performance storage from among multiple storages each having different performance, one of the storages to data in the order the access frequency of the data is high;
- a identifying unit that identifies, as the target for relocation from among pieces of data to each of which a storage is allocated by the allocating unit, data to which a storage that is different from the storage that currently stores the data is allocated;
- and
- a control unit that relocates the data identified, by the identifying unit, as the target for the relocation.
A non-transitory computer-readable storage medium having stored therein an operation management program causing a computer to execute a process comprising:
- allocating, sequentially by giving priority to a high performance storage from among multiple storages each having different performance, one of the storages to data in the order the access frequency of the data is high;
- identifying, as the target for relocation from among pieces of data to each of which a storage is allocated, data to which a storage that is different from the storage that currently stores the data is allocated;
- and
- instructing a control device that controls the storages to relocate the data identified as the target for the relocation.
An operation management method comprising:
- allocating, using a computer sequentially by giving priority to a high performance storage from among multiple storages each having different performance, one of the storages to data in the order the access frequency of the data is high;
- identifying, as the target for relocation from among pieces of data to each of which a storage is allocated, data to which a storage that is different from the storage that currently stores the data is allocated;
- and
- instructing a control device that controls the storages to relocate the data identified as the target for the relocation.
