The QLogic Virtual Fabric Extension Module is another example of IBM's innovation. IBM was among the first to deliver Fiber Channel over Ethernet (FCoE) across System x and BladeCenter and this module takes this a step further by offering clients IO convergence inside the chassis. Clients using the BNT 10 Gb switch for their LAN traffic can now combine it with this module and the QLogic CNA to converge their LAN and SAN on a single network. This not only offers a simplified fabric, but also offers significant savings over separate 10 Gb/8 Gb infrastructure. Other than the cost and management savings, this solution provides the flexibility to upgrade existing chassis to implement IO convergence without replacing existing 10 Gb switch.
