摘要： One or more switches are interposed between a controller portion and a storage device. When transmission of a command to a certain storage device fails, a command is transmitted starting from an upstream side to a downstream side of a path between the controller portion and the switch to which the certain storage device is connected, and when command transmission fails while transmitting a command from a kth switch (k is an integer of 0 or more) which is connected to a (k+1)th switch and is one level upstream of the (k+1)th switch or from any port of the controller portion, it is determined that a failure has occurred in a power source that supplies power to the (k+1)th switch.

摘要： 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.

摘要： There are provided a cache region that stores write data from a host device, storage media, a data storage region for the storage media, and a comparison unit. A first comparison object is generated for N items of write data on the cache region and the N items of write data are transferred to the data storage region. Write data is read from a designated address of the data storage region and this write data is written to the storage media. When N items of write data have been read, a second comparison object is generated in respect of the write data. The comparison unit compares the first comparison object and the second comparison object, and if the result of the comparison is a mismatch, the N items of write data on the cache region are again transferred to the data storage region.
