Integrating seamlessly into existing backup applications and processes, the HP StorageWorks 9000 Virtual Library System (VLS 9000) accelerates backup performance in complex SAN environments while improving overall reliability. Emulating popular tape libraries and tape drives, the VLS9000 matches the existing data protection environment, removing the need to change backup software or monitoring policies. By emulating multiple tape drives simultaneously, more backup jobs can be done in parallel resulting in reduced backup times. Additionally, because the data resides on disk, single file restores are exceptionally fast.The VLS9000 simplifies your SAN environment by providing more virtual devices, reducing the complexity of shared storage while maintaining the manageability of a single piece of hardware. As your environment changes, the VLS9000 adapts to it - host masking and mapping ensure that only the appropriate hosts have access to the VLS9000. As storage requirements grow, the VLS9000 matches the environment by scaling both capacity and performance. Although the VLS9000 is a multi-node product, it is managed as a single virtual library device.
