PRODUCT OVERVIEW

Using HP Virtual Connect FlexFabric 10Gb/24-port Modules is the simplest, most converged and flexible way to connect virtualized server blades to any data or storage network. VC FlexFabric modules eliminate up to 95% of network sprawl at the server edge with one device that converges traffic inside enclosures and directly connects to LANs and SANs. Using Flex-10 technology with Fibre Channel over Ethernet and Accelerated iSCSI, these modules converge traffic over high speed 10 Gb connections to servers with HP FlexFabric Adapters.

Each module provides four adjustable connections (three data and one storage or all data) to each 10 Gb server port. You avoid the confusion of traditional and other converged network solutions by eliminating the need for multiple Ethernet and Fibre Channel switches, extension modules, cables and software licenses. Also, Virtual Connect wire-once connection management is built-in, enabling server adds, moves, and replacement in minutes instead of days.<br><br This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 7025-01-616-8564, indicating validated use in U.S.

government and defense logistics supply chains.
