HA Recource allocation

[vSohill]

Hi HA community,

The follwoing screenshot from my mgmt cluster, it shows total memory 23.73 GB and 5% been reserved for HA.

when I am looking in the Resource allocation tab , What is 5422 MB is it  the 5%  which is not if I am right ??

Thank you

Those are two different things. 1) the first reserved failover capacity is referring to the resources you have manually set aside for HA admission control. Considering you have a 3 node cluster, 5% seems extremely low and I would recommend you set it to 33% at a minimum so you can always guarantee the restart of VMs when a single host fails 2) the second screen shows how much memory is actually being reserved in your environment.
