  • Publication number: 20060179163
    Abstract: In the disk array device, the critical I/O from the host can be responded regardless of the state of the storage unit to be accessed and without occurring an answer delay and system down so that both of the I/O performance and the system reliability can be improved. In the disk array device, a DKC to control data storage to a HDD includes CM to perform the data I/O processing to the HDD responsive to the I/O request from the host. A response impossible state due to the life extension process may be occurred in the HDD. The DKC determines the specified I/O pattern in the received I/O and previously performs the cache control to the critical I/O target data associated with the specified I/O pattern using a CM according to the information in the DB. The critical I/O request is responded using the cache resident data on the CM.
