Abstract:
Proposed are a storage apparatus and a control method thereof capable of improving the response performance to a read access of various access patterns. When data to be read is not retained in a data buffer memory, upon staging the data to be read, a processor performs sequential learning of respectively observing an access pattern in units of blocks of a predetermined size and an access pattern in units of slots configured from a plurality of the blocks regarding an access pattern of the read access from the host apparatus, and expands a data range to be staged as needed based on a learning result of the sequential learning.

Claim (Index 8):
A control method of a storage apparatus which provides, to a host apparatus, a storage area for reading or writing data,\n wherein the storage apparatus includes: one or more storage devices which provide the storage area; a processor which reads data to be read from the storage area according to a read request given from the host apparatus; and a data buffer memory which temporarily retains the data read from the storage area, wherein the control method comprises: a first step of the processor, when the data to be read is not retained in the data buffer memory, executing staging of reading the data to be read from the storage area into the data buffer memory, sending the staged data to be read to the host apparatus, and, upon staging the data to be read, performing sequential learning of respectively observing an access pattern in units of blocks of a predetermined size and an access pattern in units of slots configured from a plurality of the blocks regarding an access pattern of the read access from the host apparatus; and a second step of the processor expanding a data range to be staged as needed based on a learning result of the sequential learning.
