During the knowledge transfer on Prism GUI, a customer asked about AHV best practices for...

In a five-node cluster with storage containers configured with a replication factor of 3, the behavior of VM High Availability when two AHV host failures occur with the non-default "Guarantee mode" enabled is as follows:

Will ensure that all VMs can restart in case of two simultaneous AHV host failures: This mode prioritizes maintaining VM availability by reserving enough resources to restart VMs even with multiple host failures, as long as at least three hosts (matching the replication factor) remain functional.
