ABSTRACT:
A disk array device having a dual controller for executing data input/output processing for disk drives in response to a data input/output request from a host computer. Each controller constituting the dual controller has an FC controller which is interface-connected to the host computer via one path of a front interface connection FC and to the disk drives via one path of a back interface connection FC, and a PBC for switching the connection destination of the back interface connection FC between the two FC-ALs loop-connected to the disk drives.
