Virtualization Optimization Capacity Mgmt best practices SAS institute

This session was on best practices re: virtualization Capacity Planning, as per experience of SAS institute.

Some of their findings:
- Memory is more important than CPU
- Memory tracking is important

They started very conservative (as most when new to virtualization) and started with a ratio of 11:1. They then used the SAS tool to track performance and behaviors and from the statistics were able to gather that they weren't using their virtual infrastructure optimally. They the determined that they could increase their consolidation ratio; from 11:1 to 20:1.

The tool name is: SAS IT intelligence for VMware VI.

Along the way they also discovered that the CPU ready measurement is an important measurement to track.
