smart copy SMI-S SAN storage pool A software feature within the automigration process that is under the control of the backup application and managed via the VLS device's SMI-S interface. This requires the backup application to support the HP smart copy interface. (Smart copy is similar to snapshot.) Allows control of the virtual tape library by a connected destination library for the purpose of implementing automigration. SMI-S support allows applications attached to the VLS to detect the virtual library configuration and to allow some users to change the state of the VLS. Storage area network. A network of storage devices available to one or more servers. Multiple disk arrays logically grouped together from which the dynamic disk filesystem allocates storage. The disk arrays in a VLS are automatically configured into one storage array. tape drive (1) A device that reads data from and writes data onto tape. (2) A software emulation of a tape drive is called a virtual tape drive. virtual tape A disk drive buffer that emulates one physical tape to the host system and appears to the host backup application as a physical tape. The same application used to back up to tape is used, but the data is stored on disk. Also known as a piece of virtual media or a VLS cartridge. Data can be written to and read from the virtual tape, and the virtual tape can be migrated to physical tape. virtual tape drive An emulation of a physical transport in a virtual tape library that looks like a physical tape transport to the host backup application. The data written to the virtual tape drive is really being written to disk. virtual tape library A disk drive buffer containing virtual tape and virtual tape drives. WWNN WWPN World wide node name. A globally unique 64-bit identifier assigned to each Fibre Channel node process. World wide port name. A unique 64-bit address used in a FC storage network to identify each device in a FC network.
