Abstract
A storage control apparatus includes a processor. The processor is configured to detect a dependency relationship between a first data access and a second data access made after passage of a delay time from the first data access. The first data access is made to a first storage area in a first storage device. The second data access is made to a second storage area in the first storage device. The processor is configured to transfer, when a current data access is made to the first storage area in a state in which the dependency relationship is detected, data in the second storage area to a second storage device before the delay time passes. The second storage device has a higher access speed than the first storage device.
Claims9
A storage control apparatus, comprising:
- a processor configured to
- detect a dependency relationship between a first data access and a second data access made after passage of a delay time from the first data access, the first data access being made to a first storage area in a first storage device, the second data access being made to a second storage area in the first storage device, and
- transfer, when a current data access is made to the first storage area in a state in which the dependency relationship is detected, data in the second storage area to a second storage device before the delay time passes, the second storage device having a higher access speed than the first storage device.
A storage system, comprising:
- a first storage device;
- a second storage device having a higher access speed than the first storage device;
- and
- a storage control apparatus including:
- a processor configured to
- detect a dependency relationship between a first data access and a second data access made after passage of a delay time from the first data access, the first data access being made to a first storage area in the first storage device, the second data access being made to a second storage area in the first storage device, and
- transfer, when a current data access is made to the first storage area in a state in which the dependency relationship is detected, data in the second storage area to the second storage device before the delay time passes.
A computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:
- detecting a dependency relationship between a first data access and a second data access made after passage of a delay time from the first data access, the first data access being made to a first storage area in a first storage device, the second data access being made to a second storage area in the first storage device;
- and
- transferring, when a current data access is made to the first storage area in a state in which the dependency relationship is detected, data in the second storage area to a second storage device before the delay time passes, the second storage device having a higher access speed than the first storage device.
