Calculating spare VM estimates

The Capacity page of the vSphere Infrastructure view provides an estimate of the additional VMs that can be added to a cluster based on a typical VM configuration. Using this estimate, you can identify the clusters with residual or spare capacity. You can customize this typical VM configuration and review the changed estimate of additional VMs that can be added to the cluster.
