Abstract
A structure of control units and storage units is provided in which, if a port for connecting the storage units fails, any storage unit in a plurality of storage unit groups can be accessed from one control unit. Specifically, a distinctively arranged structure is provided in which dual paths are provided, with each path connected to a plurality of storage unit groups, whereby, in normal operation, dual paths are used as data transfer paths to allow faster access. When a port or path failure occurs, the dual paths allow RAID functions to be maintained.
