Introduction

As IT professionals we apply technology solutions to business problems. We adapt to the technologies at hand and utilize them in the most efficient, cost effective manner to fulfill the needs of our customers.

Some technologies have allowed us to deliver the complete power of a system to the end user and other technologies have not taken advantage of the available resources.

Proposed Ratio – The original virtualization proposal suggested that per ESX server there could be 18 low/small utilization virtual servers and 14 mid utilization virtual servers

Actual Projected Ratio – The actual ratio shows the original proposal to be too conservative. The numbers reflected below are estimates based on current ESX server utilization numbers and reflect a more accurate picture of the hardware utilization.
