摘要： Interfaces of SAN and NAS, prevents data miss even when a trouble occurs and makes it possible that an arbitrary number of NAS interfaces access the same file system with high performance. A storage system includes multiple interfaces for external connection, multiple disks accessed from multiple interfaces, and a shared memory accessed from multiple interfaces. The multiple interfaces are block interfaces executing disk block I/O request, and file interfaces of file servers executing file I/O request. A file system in the file servers is constructed in a part of the disks, and a log storage area holding change log of the file system, and a management file server information storage area holding information of managing file server performing exclusive access control of file system and management of log storage area are formed in the shared memory.

摘要： A disk array system of the type that each controller has an independent and dedicated cache. The disk array system can change control of a desired volume between desired controllers without suspending the system. When volumes are taken over between controllers, a switch-source controller de-stages data of a subject volume on the data cache to a storage subject disk to maintain the disk content reflection (coherency). Even if each controller has an independent and dedicated cache, a desired volume can be taken over between desired controllers without suspending the system. Each controller has a configuration manager which stores the controller number of a switch-destination controller to allow automatic volume take-over and automatic control by the original controller.

摘要： Data can be recovered at the point in time when the consistency is provided, without increasing a load on the host. The control program 118 updates the snapshot generation at the point in time when the snapshot is taken for each occurrence of the point in time when the snapshot is taken. In cases where new data are written into PVOL1 from the point in time when the snapshot has been taken until the next point in time when the snapshot is taken, the old data are saved by the CoW in DVOL1 and new data are written into PVOL1. Each time new data are written into PVOL1, the update differential data, which are the copy of this data, are prepared and written into DVOL1. The opportunity of providing the consistency of PVOL1, which occurs independently of the operations of the user of the host computer 20, is taken and the update differential generation, which is the generation of update differential data at each point in time where the update differential data has been set, is updated each time the opportunity is taken. The recovery of PVOL1 is conducted based on the managed update differential generation and snapshot generation.

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.
