The cluster first determines the slot size, from which it can then determine how many ‘slots’ the cluster can support. The cluster can then work out how many ‘slots’ need to be left free to support powering on VMs in the event of a host failure. So, how is the slot size calculated? Slot size is made up of both CPU and memory. How to Create a Custom Slot Size Configuration Generally, one virtual machine = 1 used slot. In the example above, I have seven powered on virtual machines and seven used slots in the cluster. To calculate the slot size for a cluster, HA uses the highest CPU reservation of any virtual in the cluster, and the highest memory reservation for any virtual machine in the cluster. Why I prefer to disable vSphere HA Admission Control So you can end up with cluster with plenty of available resources, but won't be able to deploy new VM. Also, most of the vSphere environments constantly grow and change. therefore, slot size have to adjusted accordingly. One can calculate average VM size and use these values for custom slot size. vmware Resource calculator virtual machine - Experts-Exchange

I'm looking at making a hardware recommendation for a customer but I'm not sure I understand how to go about sizing everything. My experience is limited to the small business realm, and the largest deployment I've worked with was using ESXi Essentials licensing. VMWare Flashcards | Quizlet How does vSphere High Availability calculate the memory slot size of a virtual machine? Virtual machine memory reservation + overhead of largest virtual machine Which das.iostatsintervaI is the default? Which VMs set your Slot Size ? - Virtu-Al.Net

If you click the host or cluster in the vSphere web console you can determine the total capacity (metric B in your question) from the Summary tab. On my system it is 43.98Ghz. And If you select the virtual machine you can determine how many cycles per second of CPU it is using (metric A) from the Summary tab.

VMware Slot Size - The IT Hollow To begin this post, we need to understand what a slot is. A slot is the minimum amount of CPU and memory resources required for a single VM in an ESXi cluster. Slot size is an important concept because it affects admission control. A VMware ESXi cluster needs a way to determine how many resources need to be available in the event of a host failure. vSphere Cluster calculator - vMusketeers vSphere Cluster calculator.
