Create a VM-VM Affinity Rule
VM-VM Anity Rules
A VM-VM affinity rule specifies whether selected individual virtual machines should run on the same host
or be kept on separate hosts. This type of rule is used to create affinity or anti-affinity between individual
virtual machines that you select.
When an affinity rule is created, DRS tries to keep the specified virtual machines together on the same
host. You might want to do this, for example, for performance reasons.
With an anti-affinity rule, DRS tries to keep the specified virtual machines apart. You could use such a rule
if you want to guarantee that certain virtual machines are always on different physical hosts. In that case,
if a problem occurs with one host, not all virtual machines would be placed at risk.
Create a VM-VM Anity Rule
You can create VM-VM affinity rules to specify whether selected individual virtual machines should run on
the same host or be kept on separate hosts.
Note If you use the vSphere HA Specify Failover Hosts admission control policy and designate multiple
failover hosts, VM-VM affinity rules are not supported.
