Server partitioning and consolidation

The concepts of server partitioning and consolidation are discussed in detail in

Chapter 2,

“

Positioning

”

on page 35.

Implementing a server consolidation solution using VMware and the x440

introduces a number of important and unique issues that you need to consider

during the planning phase of your project.

In particular the x440 configuration needs to be carefully sized to meet the

resource requirements of the VMware operating system, the guest operating

systems, and the applications being deployed.

A detailed discussion on planning, sizing, and implementing VMware solutions

on the x440 can be found in the redbook

Server Consolidation with the IBM

xSeries 440 and VMware ESX Server

, SG24-6852.

Operating system considerations

In line with the overall message of providing application flexibility to meet the

varying needs of our enterprise customers, the x440 is optimized for numerous

operating system and application solutions. For the latest operating system

support information, go to:
