Expanding the power of the HP StorageWorks Enterprise Virtual Array (EVA), the HP StorageWorks 300 Virtual Library System EVA Gateway accelerates backup performance in complex SAN environments while improving overall reliability. Integrating seamlessly into existing backup applications and processes by emulating popular tape libraries and tape drives, the HP VLS 300 EVA Gateway matches the existing data protection environment, removing the need to change backup software or monitoring policies. Additionally, because the VLS EVA Gateway uses HP EVAs as the storage pool, ease of use is maintained throughout the system. By emulating multiple tape drives simultaneously, more backup jobs can be done in parallel resulting in reduced backup times and, because the data resides on disk, single file restores are exceptionally fast.The HP Virtual Library System EVA Gateway simplifies your SAN environment by providing more virtual devices and leveraging existing switches and HP EVA infrastructure. The result is the ability to vastly increase scale yet reduce the complexity of shared storage while maintaining the manageability of the system. As your environment changes, the HP Virtual Library System EVA Gateway adapts to it - host masking and mapping ensure that only the appropriate hosts have access to the HP Virtual Library System.This product comes with:Two HP StorageWorks 300 Virtual Library System Gateway nodes - each enabled for 20 TB [10 LUNS];Five HP StorageWorks 300 Virtual Library System Capacity Expansion Licenses [10 TB] (T4430A);One HP Procurve 2824 Ethernet switch;One HP Procurve 2524 Ethernet switch;Two USB to LAN converters;Command View Tape Library Software CD;Installation Poster;HP 300 Virtual Library System Gateway Documentation CD;HP Command View Tape Library Software Documentation CD;System recovery CD.
