Abstract
A receiver unit receives data write commands for a memory device. A control unit determines a use situation of an RMW cache used in a read-modify-write process by the memory device, on the basis of write sizes, a reception frequency, and the number of received commands. A control unit decides whether or not to execute a read-modify-write process by a storage control apparatus on the basis of the determination result.
Claims12
A storage control apparatus comprising:
- a receiver unit configured to receive commands of data write into a memory device;
- and
- a processor configured to determine a use situation of a cache used in a read-modify-write process by the memory device on the basis of write sizes, a reception frequency, and the number of received commands, and decide whether or not to execute a read-modify-write process by the storage control apparatus on the basis of a determination result.
A non-transitory computer-readable storage medium storing a control program that causes a computer to perform a procedure comprising:
- receiving commands of data write into a memory device;
- determining a use situation of a cache used in a read-modify-write process by the memory device on the basis of write sizes, a reception frequency, and the number of received commands;
- and
- deciding whether or not to execute a read-modify-write process by the computer on the basis of a determination result.
A control method comprising:
- receiving, by a computer, commands of data write into a memory device;
- determining, by the computer, a use situation of a cache used in a read-modify-write process by the memory device on the basis of write sizes, a reception frequency, and the number of received commands;
- and
- deciding, by the computer, whether or not to execute a read-modify-write process by the computer on the basis of a determination result.
