摘要：
A disk array controller which includes a channel interface unit for connecting a host computer through a first type channel, a channel interface unit for connecting a host computer through a second type channel, a plurality of disk interface units provided with an interface with a magnetic disk unit respectively, a cache memory unit, and a shared memory unit. The number of access paths connected to said cache memory unit is less than the number of access paths connected to the shared memory unit.
