Abstract
A bandwidth between a second processor and a second memory is higher than a bandwidth between a first processor and a first memory. The first memory stores a read command from a host computer. The first processor analyzes a content of the read command, and in accordance with a result of the analysis, requests read data from the second processor. In response to the request from the first processor, the second processor reads the read data from one or more storage drives and stores the read data in the second memory. The second processor notifies the first processor that the read data is stored in the second memory. The first processor transfers the read data read from the second memory, to the host computer without storing the read data in the first memory.
