Abstract
The transfer data amount between a server and storage is effectively reduced, and the broadband of an effective band between the server and the storage is realized. An interface device is located in a server module, and, when receiving a read request issued by a server processor, transmits a read command based on the read request to a storage processor. In a case where a reverse-conversion instruction to cause the interface device to perform reverse conversion of post-conversion object data acquired by converting object data of the read request is received from the storage processor, DMA to transfer post-conversion object data stored in the transfer source address on a storage memory to the transfer destination address on the server memory while reverse-converting the post-conversion object data is performed.
