Server compute and memory should be balanced, and both sized to be able to handle the anticipated VDI workload at scale. 85% to 90% utilization of server compute and memory is achieved at scale during the login phase for 2,500 Login VSI knowledge workers.
Estimating VM density based on memory utilization is relatively easy to calculate. Understanding the CPU demand for a VDI workload can be more difficult and may require testing.
