DATA ACCESS RESPONSE SYSTEM, STORAGE SYSTEM, CLIENT DEVICE, CACHE DEVICE, AND DATA ACCESS RESPONSE SYSTEM ACCESS METHOD

摘要

A data access response system includes a client device such as a personal computer and a work station and a storage system consisting of a storage device for storing data and a control device for managing the storage position, wherein latency for the access request from the client device is reduced. More specifically, the system includes a storage device (3), a cache device (4), a client device (7), and a control device (2) for managing the storage position of data stored in the storage device (3) and the cache device (4) which communicate with one another via a network (5). When the control device (2) receives a request to access the data managing the storage position from the client device (7), the control device (2) instructs transfer to the storage destination device containing the data and the storage destination device which has received the transfer instruction directly returns a response message having the data storage position information to the client device (7).
