We were having some work done in one of our datacenters recently that was going to cause a short outage. In anticipation of that outage I moved as many workloads as possible to hosts residing in a different datacenter (and turned DRS way down). The hosts in the destination datacenter seemed to run out of resources much quicker than expected. I was told that was because HA was still enabled and therefore it was reserving resources on those hosts in case of an HA event. Is that true? Or are 100% of resources available, even with HA enabled? We are running version 5.5 update 1.
Thanks in advance for any information on this.
