Manual

Most medium and large-sized IT organizaons have deployed several generaons of virtualized servers, and
they have become more comfortable with the performance and reliability with each deployment. As IT
organizaons increased virtual machine (VM) density, they reached the limits of vSphere soware, server
memory, CPU, and I/O.
A new VM engine is now available and this document describes how it can help IT organizaons maximize
use of their servers running VMware® vSphere® 5.1 (henceforth referred to as vSphere 5.1).

Harnessing the Power
In a survey conducted by IT Brand, IT professionals said the
average number of VMs per server would almost double in the
next 24 months.
