environment.

NOTE:

Throughout this document, System Center Virtual Machine Manager 2008
R2 is referred to as

VMM2008 R2

.

This guide discusses the use of NPIV in conjunction with the pass-through disk
Hyper-V configuration to achieve maximum storage I/O performance and related
individual virtual machine specific statistics.

This guide also explores the value of using NPIV technology with QLogic‘s
performance and resource optimization (PRO) management pack in Microsoft
System Center VMM2008 R2.

Overview

Fibre Channel host bus adapters are playing an increasingly critical role as data
centers accelerate virtualization deployments. With servers, storage, and storage
area networks (SANs) becoming virtual, host bus adapters need to ensure that
each virtual machine workload accesses only its assigned storage.

This guide describes how and why data center system administrators should
setup and deploy the QLogic Fibre Channel adapter solution in Microsoft
Windows Server 2008 R2 Hyper-V environments in conjunction with Microsoft
System Center VMM2008 R2 and an HP

®

Channel storage array.
