Abstract
According to one embodiment, an information processing apparatus includes a determination module and a cache module. The determination module is configured to determine whether an access request from a host to the hard disk drive is a request for accessing a preset number of or more consecutive sectors in a hard disk drive. The cache module is configured to use a storage apparatus as a cache for the hard disk drive, and the cache module is configured not to use the storage apparatus as the cache when it is determined that the access request is the request for accessing the preset number of or more consecutive sectors.
Claims18
An information processing apparatus comprising:
- a determination module configured to determine whether an access request from a host to the hard disk drive is a request for accessing a preset number of or more consecutive sectors in a hard disk drive;
- and
- a cache module configured to use a storage apparatus as a cache for the hard disk drive, and the cache module being configured not to use the storage apparatus as the cache when it is determined that the access request is the request for accessing the preset number of or more consecutive sectors.
A hybrid storage apparatus comprising a hard disk drive and a storage apparatus;
- a determination module configured to determine whether an access request from a host to the hard disk drive is a request for accessing a preset number of or more consecutive sectors in a hard disk drive;
- and
- a cache module configured to use a storage apparatus as a cache for the hard disk drive, and the cache module being configured not to use the storage apparatus as the cache when it is determined that the access request is the request for accessing the preset number of or more consecutive sectors.
A cache method which uses a storage apparatus as a cache for a hard disk drive, the method comprising
- determining whether an access request from a host to the hard disk drive is a request for accessing a preset number of or more consecutive sectors in a hard disk drive;
- and
- a cache module configured to use a storage apparatus as a cache for the hard disk drive, and the cache module configured not to use the storage apparatus as the cache when it is determined that the access request is the request for accessing the preset number of or more consecutive sectors.
- not using the storage apparatus as a cache when it is determined that the access request is the request for accessing the preset number of or more consecutive sectors.
