Now assess whether your physical virtualization environment and technology will be able to meet your performance requirements for your SharePoint farm. (See virtualization boundaries in previous section.)
Plan and optimize your host environment servers by ensuring that each has enough physical resources to host the planned virtual SharePoint servers. Don’t forget to make facility for failover cluster host servers for your virtual machines.
Plan and optimize your virtualization platform layer:
Understand the virtualization overhead with different mixes of SharePoint VM workloads
Understand the performance bottlenecks in the underlying storage and network infrastructure, both from a cumulative as as individual path perspective.
Group complimentary virtual SharePoint machine workloads (a workload is a single virtual machine) for optimal performance on a physical host based on the performance characteristics of your virtual machines
Plan and optimize the guest operating system layer :
Use Windows Server 2008 as the guest operating system (See information on “enlightenments”)
Optimize each virtual guest by ensuring that the 4 physical and virtual resources utilization are maximized. Secondly maximize application and configuration for each guest machine in your virtual SharePoint environment
Finally continually monitor performance and adapt configuration for optimal performance for each host server based on what is happening in your organisation. Plan and cater for peak usage scenarios.
