ABSTRACT:
There is provided a storage control program, a storage control apparatus, and a storage control method capable of improving a random read performance for a logging operation.A storage control program allows a computer to control a storage apparatus and causes the computer to execute: a data write step that logs data to the storage apparatus based on a write request from outside; and a position information control step that can write position information in a cache apparatus connected to the computer through a network. The position information is equivalent to correspondence between a logical position specified by the write request and a physical position in the storage apparatus where the data write step logs data.
