MAGNETIC DISK STORAGE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To realize the effective use of a band having a full duplex path at a low cost in the case of using the full duplex path for connection between a switch part and a cache memory part in a switch connection type disk array. SOLUTION: An access path 10 shared by a host interface part 4 or a disk interface part 6 in order to access the cache memory part 7 is constituted of the full duplex path. An access request to the cache memory part 7 which is issued through the shared access path 10 is controlled so that a read access and a write access are alternately issued. COPYRIGHT: (C)2004,JPO
