CA 2451048

Emulation of a small computer system interface (SCSI) library storage is provided in a virtual data storage subsystem having an automated tape library. This allows the ability to access or store a logical volume of data. Medium changer commands as used in SCSI and other open system interfaces are mapped to library function commands as commonly used in an enterprise server environment. This allows full transparent usage of virtual tape storage available in the enterprise server environment as open system storage.

L'émulation d'une mémoire de type bibliothèque à petites interfaces de système informatique (SCSI) est assurée dans un sous-système de mémoire de données virtuelle comportant une bibliothèque de bandes automatisée. On permet ainsi l'accès ou la mémorisation d'un volume logique de données. Les instructions du changeur de support, telles qu'elles sont utilisées dans l'interface SCSI et dans d'autres interfaces de système ouvertes, sont mappées sur les instructions de fonctions de la bibliothèque, tel que cela est communément utilisé dans un environnement de serveur d'entreprise. On permet ainsi une utilisation totalement transparente de la mémoire de bandes virtuelles disponible dans l'environnement de serveur d'entreprise sous la forme d'une mémoire de système ouverte.
