QLogic Achieves Near-Native Fibre Channel I/O Performance on Windows Server 2008 Hyper-V

Configuration with QLogic Fibre Channel Adapters Sets New Standard for Server Virtualization Efficiency

ALISO VIEJO, Calif., June 26, 2008 – QLogic Corp. (NASDAQ:QLGC), a leader in networking for storage and high performance computing (HPC), today announced that QLogic and Microsoft achieved industry leading 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.

From the qlogic website, it looks like they used pass-through disk

“The microkernelized architecture of Windows Server 2008 Hyper-V is designed from the ground up to optimize I/O performance. With support for features like pass-through virtual machine disk access, customers can receive high I/O performance for SAN-attached servers when combined with high performance products such as QLogic 8Gb adapters.”
