If you overstretch your resources, some features like High Availability failover may not function as planned. Tweaking them can save you from buying additional host resources. In this case you must set a HA priority level for each VM to ensure that critical workloads are moved to new hosts first in the case of a failure. They are all fairly self-explanatory. From individual system information to overall strategy, this template helps you design your response to a total loss of power, natural disaster, or any other event that could shut down your IT systems. Overcommitting resources can also lead to general performance problems, so it is in your best interest to use Admission Control to keep a close watch on overall capacity. Image source: VMware video on HA. You might be trying to power on new VMs, only to run into errors as you exceed your Admission Control rules. Ready to Launch Your Cloud? In some cases, you may need to disable Admission Control completely — as when overprovisioning VMs beyond the total resources allowed. Reserving resources for your VMs guarantees that they will have a certain amount of memory or CPU power allocated to them. If your entire cluster of VMs dies, you have the capacity to completely failover. Another reason? This is because the Slot size is tied to your largest VM. Another option is to avoid using Reservations unless necessary, in which case HA will default to the normal, tiny slot size, and your VMs should all move to the new host. Prepare for an IT outage by filling out this disaster recovery worksheet. There are three types: Host failures the cluster tolerates Percentage of cluster resources reserved as failover spare capacity Specify failover hosts They are all fairly self-explanatory. Talk to an infrastructure consultant today. This is where you can manually change your Slot size in order to allow all of your machines to move to a new host in the case of failure. If it is reserved, then your failover host will think it can only fit a few of these VMs, when really it could failover your single large VM as well as all of your other smaller ones. However, HA will not halt the failover at the automatic slot limit any longer. The host, of course, depends on the underlying hardware at your cloud service provider or within your own data center facility. Choose VMware HA.
