Abstract
Provided is a storage subsystem capable of inhibiting the deterioration in system performance to a minimum while improving reliability and availability. This storage subsystem includes a first controller for controlling multiple drive units connected via multiple first switch devices, and a second controller for controlling the multiple drive units connected via multiple second switch devices associated with the multiple first switch devices. This storage subsystem also includes a connection path that mutually connects the multiple first switch devices and the corresponding multiple second switch devices. When the storage [sub]system detects the occurrence of a failure, it identifies the fault site in the connection path, and changes the connection configuration of the switch device so as to circumvent the fault site.
