To access VMware High Availability settings, right click your Cluster in the Inventory panel of the vSphere Client, and then click Edit Settings. Configuration options for Admission Control This post will introduce the concepts of slot sizes and configuration of Admission Control to allow more VMs to move between hosts when you have turned on High Availability in vSphere/vCenter. Tweaking them can save you from buying additional host resources. Another reason? You might be trying to power on new VMs, only to run into errors as you exceed your Admission Control rules. Overcommitting resources can also lead to general performance problems, so it is in your best interest to use Admission Control to keep a close watch on overall capacity. HA keeps your VMs from failing by pooling VMs and hosts in a cluster, relaunching failed VMs on alternate hosts. If you overstretch your resources, some features like High Availability failover may not function as planned.

The number of hosts that are connected, not in maintenance mode, and have no vSphere HA errors.It’s easy to provision additional VMs and increase resource commitment from your overall resource pool using the vSphere web portal. Total number of powered on virtual machines in cluster.The total number of slots not counting the used slots or the available slots. The remaining slots are available to power on new virtual machines. vSphere HA reserves the required number of slots for failover. The number of slots available to power on additional virtual machines in the cluster. This is because some virtual machines can take up multiple slots. It can be more than the number of powered-on virtual machines if you have defined an upper bound for the slot size using the advanced options. The number of slots assigned to powered-on virtual machines. The sum of the slots supported by the good hosts in the cluster. This pane displays the following information about the cluster: When you select the Host Failures Cluster Tolerates admission control policy, the Advanced Runtime Info pane appears in the vSphere HA section of the cluster's Monitor tab in the vSphere Web Client.
