ESX Cluster Discussion

[fitzie22]

I am currently building a one cluster environment at my company because after 5 years working with separate dev and prod clusters and the low expense of hardware it was to me a no brainer. So the question from management is how do we make sure that if one of the hosts in the cluster fails that only the production vm's will come up on the other hosts. That is easy with the restart priority in the HA settings. Now as far as making sure that if in fact a qa vm decided to have a runaway process that it would not affect the performance of the production vm's I was thinking of setting limits on the qa one's rather than reservation on the prod ones because if there was an outage and the reservation could not be met it would not start the vm's with reservations. Any other suggestions would be greatly appreciated so I have all my info. Thanks

If admission control is enabled, HA will keep enough free resources to be able restart VMs.

You can also disable HA for individuals VMs - so in the event of a failure the VM will not start - this is done in the per VM HA settings -
