摘要： Erroneous deletion of data due to a collision of digest information during data de-duplication using digest information is prevented. When backup data is stored on a backup server 1100, digest information of the backup data is generated and stored in a digest information management table 4200. In addition, when a backup data storage request is made to the backup server 1100, a digest information verification control sub-program 1127 generates digest information of data to be backed up, and performs verification against the digest information of the backed up data already stored on the backup server 1100. If, by this verification, it is found that backed up data having the same digest information is already stored, de-duplication is realized by reusing the existing backed up data without newly storing the data to be backed up.

摘要： A storage device and method for ensuring the provision of data as complete files in a storage device capable of processing both block input/output I/O and file I/O. For each logical volume, an attempt is made to unmount logical units (LUs) storing files triggered by a session start request for block I/O (login request) such as iSCSI, and to recognize (mount) files of logical units triggered by a session completion request for block I/O (Logout request). Block access processing units may also create a replication of a specified logical unit and set a relevant replicated logical unit as a logical unit for access.

摘要： In a computer system having a storage device, switches and hosts respectively connected by a network, in accordance with an ID of a logical volume of the storage device and an IP address of a host, access control configuration of the logical volume is performed relative to the storage device, the IP address of the host is converted into a MAC address, the MAC address of the host is converted into a port ID of the switch connected to the host, and addition of the port to virtual local area network (VLAN) is performed for the switch. Logical unit number (LUN) masking and VLAN configuration essential for security countermeasure of IP-SAN (Internet protocol-storage area network) can be managed collectively by a system administrator so that the running cost of IP-SAN can be lowered.
