• Size VM for only minimal/appropriate number of CPUs and memory.

• If exact workload is not known, start with fewer vCPUs and increase as needed.

• Use Capacity Planner to analyze current environment and provide resource utilization metrics

for sizing.

• Overcommitting CPU is practical, as long as ESXi host is not saturated or while VMs are not

bottlenecked on system resources.

• For lower-tiered workloads, reasonable over commitment can increase aggregate throughput

and maximize license savings - The consolidation ratio varies depending on workloads. VMworld 2018 Content: Not for publication or distribution
