5 QLogic Management PRO

Pack and NPIV Technology

Overview

Increasing server consolidation results in multiple workloads exercising the

capabilities of the host server Fibre Channel adapter. High I/O workloads, such

as Microsoft

SQL Server

data management software or Microsoft Exchange

Server e-mail messaging and collaboration software, may coexist with high

throughput workloads, such as backup, on the same host running Microsoft

Hyper-V virtualization technology.

These multiple workloads can easily overwhelm the capabilities of existing 4-

gigabit (Gb) Fibre Channel adapters or even the new 8Gb Fibre Channel

adapters. The result is less than optimum I/O performance and reduced ability of

the administrator to fulfill quality-of-service related service level agreements

(SLAs). Specific scenarios related to suboptimum I/O performance include:

 Multiworkload I/O activity on a physical adapter port

 Multiworkload I/O activity on N_Port ID virtualization (NPIV)-enabled virtual

adapter ports

Solution

A PRO Enabled Fibre Channel adapter management pack for VMM2008 that

monitors the adapter‘s physical or NPIV virtual host bus adapter ports (if

enabled) provides the administrator with maximum flexibility in optimizing I/O

performance on the SAN-attached Hyper-V hosts.

The QLogic PRO Pack for VMM2008 R2 will be available at the following web

site beginning November 2009:
