You’re sizing a pooled host pool for 180 concurrent knowledge workers using Windows 11 Enterprise multi-session and Microsoft 365 Apps. Your testing indicates a medium workload of roughly 6 users per vCPU. You plan to target about 70% CPU utilization at capacity. How many D8as v5 VMs should you provision?

First, calculate the total vCPUs needed: 180 users / 6 users per vCPU = 30 vCPUs. Next, account for the target CPU utilization: 30 vCPUs / 0.70 (70%) = 42.86 vCPUs. Since D8as v5 VMs have 8 vCPUs each, divide the total required vCPUs by the vCPUs per VM: 42.86 vCPUs / 8 vCPUs per VM = 5.36 VMs. You must provision whole VMs, so round up to the next whole number, which is 6 VMs. Incorrect options: 4 VMs (32 vCPUs) would be insufficient, as 42.86 vCPUs are needed. 5 VMs (40 vCPUs) would also be insufficient, as 42.86 vCPUs are needed. 8 VMs (64 vCPUs) would be an overprovision, leading to unnecessary cost.
