摘要： The disk controller has a plurality of channel control units, a plurality of cache memories, a plurality of disk control units, and a plurality of internal switch units. Each channel control unit or disk control unit sends to one of the cache memory units a request packet requesting execution of processing. The cache memory unit sends a response packet in response to the received request packet. Each internal switch unit monitors the request packet sent from the channel control unit or disk control unit, and judges whether or not the response packet to the request packet has passed through the internal switch unit within a first given time period since the passage of the request packet. In the case where the response packet has not passed through the internal switch unit within the first given time period, the internal switch unit sends a failure notification.

摘要： Provided are a storage controller and storage control method capable of improving the transaction performance. This storage controller includes a disk controller for receiving a read command and a write command from a host computer, and an external disk controller and an internal disk device for sending and receiving data to and from the disk controller. A storage device of the external disk controller or the internal disk controller processes the access from the disk controller in physical sub-block units. When the disk controller is to access the storage device of the external disk controller or the internal disk device in logical sub-block units in which an additional code containing a guarantee code is added to user data, it makes such access in minimum common multiple units of logical sub-blocks and physical sub-blocks, and changes the guarantee code length.
