Question about Admission Control in HA cluster configuration

[zhangfred_vm]

Dear firends,

There is a check box in the Admission Control Option in HA cluster configuration.

what is the availability constraints?

Does it mean the Reserved Resource constraints?

thanks

This basically means, if they're aren't enough resources left in the cluster to service the VM's, don't let them start.

You can set priority levels on a per-vm basis which will allow the most important machines to start first, but if once the resources are used up, that's it.
