QLogic announced that QLogic and Microsoft achieved performance results that demonstrate near-native transaction performance for a virtualized computing environment. The companies tested storage area network (SAN)-attached, Windows Server 2008 Hyper-V virtual machines and achieved I/O performance that closely matches the 200,000 IOs per second performance native with QLogic 8Gb adapters and Windows Server 2008. By comparison, I/O performance on Windows Server 2008 Hyper-V, the hypervisor-based virtualization technology that is a feature of select versions of Windows Server 2008, was at least 90 percent and as much as 97 percent of the native I/O performance across a data range for enterprise applications.
