Cluster disk array system and a method for operating the cluster disk array system

摘要

A cluster disk subsystem has a cluster structure formed of a plurality of disk array units connected by a high-speed cluster connection network. When the cluster disk subsystem is operated, logical partitioning is set up to the high-speed connection network to partition the cluster. The cluster disk subsystem is operated under the condition that a disk array unit including a disk array control unit, and the other disk array units are assigned to different users. Thus, when the system is operated, the independency of loads and data can be assured between the users, and the parts of the partitioned cluster can be assigned to different users.
