Deploy the virtualized environment on the same cluster if the cluster goes beyond the host boundary.
Segment redundant elements on a different cluster, or ensure that the redundant elements are not on the same host.
Create a tiered or segmented cluster infrastructure that isolates critical applications, such as CMS, from other virtual machines.
Plan for rainy day scenarios. Do not configure resources only for traffic or performance on an average day.
Do not oversubscribe resources because this affects performance.
Monitor the server, host, and virtualized environment performance.
Important:
The values for performance, occupancy, and usage can vary. A virtual machine might run at 50% occupancy. If the CPU occupancy exceeds 60% or the CMS real-time report mismatches the refresh rates, you could experience performance issues.
