摘要： A storage system having a plurality of disk controllers for accepting computer access through a SAN, and a plurality of file servers for accepting computer access through a LAN. The disk controllers and file servers are connected through a connection unit to a plurality of disk drive units in a disk pool. A disk pool management unit manages the relationships between the disk controllers and file servers and the disk drive units used by the respective disk controllers and file servers, and sends information identifying the usable disk drive units to the respective disk controllers and file servers. The disk controllers and file servers use the disk drive units based on the received usable disk information.

摘要： A hybrid-type storage system having both SAN and NAS interfaces can be implemented by simple hardware capable of carrying out a SAN function independently of a NAS function and a NAS load. To be more specific, a controller of the storage system comprises a NAS controller for accepting an I/O command issued for a file unit and a SAN controller for accepting an I/O command issued for a block unit. The NAS controller converts an I/O command issued for a file unit into an I/O command issued for a block unit, and transfers the I/O command issued for a block unit to the SAN controller. The SAN controller makes an access to data stored in a disk apparatus in accordance with an I/O command received from the SAN or from the NAS controller as a command issued for a block unit. The NAS and SAN controllers are capable of operating independently of each other.

摘要： A storage system which comprises a disk controller and a disk device having original volumes for backup and a storage pool for backup data. It incorporates a differential management program which checks whether the original volumes for backup are updated or not; a pool management program which allocates a disk area to the storage pool for backup data; a performance management program which manages the performance of each volume; and a backup control program which performs total backup control. A backup method by which recovery within a user-specified recovery object time is possible is selected according to the restore performance calculated by the performance management program and the total size of changed blocks after backup acquisition as counted by the differential management program.
