摘要： A method for backing up the data of a disk array system having network file server and storage area network functions easily and rapidly without using a route for data to be not backed up. Upon receipt of a backup request, a network file server module copies files on the disk array system's regular volumes to a backup volume. The network file server module then requests a storage area network module to copy the files to an external storage device. Finally, the storage area network module copies the current contents of the backup volume to the external storage device. The network file server module can limit the data to be backed up, thereby reducing the backup time requirements. The load on a LAN does not increase because the storage area network module acquires the data to be backed up. The processing speed increases thanks to backup load distribution within the disk array system.

摘要： By incorporating a referral mechanism, a failover method and system for remotely mirrored clustered file servers enables a client computer to transparently access a remotely mirrored file system during a failover of a first NAS (network attached storage) storing the file system. The first NAS is clustered with a second NAS that takes over the IP address of the first NAS on failover. A mirroring relationship is established between the first NAS and a third NAS whereby a copy of the file system is replicated to the third NAS. A referral is created on the second NAS, such that an access attempt from the client computer for accessing the first file system that is directed to the second NAS following IP address takeover from the first NAS after failover is referred to the third NAS by the referral to enable the client computer to access the copy of the file system.

摘要： One code (a compressed redundant code) is created based on a plurality of first redundant codes, each created on the basis of a plurality of data units, and this compressed redundant code is written to a nonvolatile storage area. This compressed redundant code is used to restore either a data element constituting a multiple-failure data, or a first redundant code corresponding to the multiple-failure data, which is stored in an unreadable sub-storage area of a partially failed storage device, and to restore the data element constituting the multiple-failure data which is stored in a sub-storage area of a completely failed storage device, based on the restored either data element or first redundant code, and either another data element constituting the multiple-failure data or the first redundant code corresponding to the multiple-failure data.

摘要： Proposed is an apparatus and method of preventing the leakage of information from an external storage apparatus even when such external storage apparatus is stolen or accessed from an unauthorized host computer. This external storage apparatus accessible from a host computer or another external storage apparatus via a network encrypts or decrypts data written from a host computer to be stored in the storage area, sends a request for existence confirmation to the host computer or the other external storage apparatus every predetermined period of time, and zeroizes an encryption key to be used in the encryption calculation for encrypting or decrypting data to be performed by the encryption calculation unit based on the result of a response from the host computer or the other external storage apparatus in reply to the request.

摘要： A storage system 1 including multiple slots for loading a block I/O interface controller, a file I/O interface controller, and any other kinds of interface controllers that are combined freely. The storage system 1 includes a management table that manages fail-over-enabled devices by grouping those devices in accordance with the interface type and the domain to which each device belongs; an information table that directs a fail-over procedure; and fail-over controlling means that takes over the processing of a failed interface controller belonging to a fail-over-enabled group. The fail-over system offers several modalities for monitoring failures, selecting takeover controllers and restoring functionality. Storage system 1 solves conventional problems by providing a system that can mount a plurality of file systems, and that resists multiple failures detected in a fail-over server.

摘要： A first storage system is provided with a first storage device containing an encryption processing unit, and a controller having an encryption processing unit and an access control unit. The access control unit judges whether a writing destination in the case of having processed a write request from an upper-level device is a first logical volume or a second logical volume, and in the case of having judged to be a first logical volume, transmits write data to a first storage device corresponding to the first logical volume without encrypting in the encryption processing unit of the controller, while on the other hand, in the case of having judged the writing destination to be a second logical volume, transmits the write data to a second storage system after having encrypted the target writing data with the encryption processing unit of the controller.
