Cluster Prerequisites

Your system must meet certain prerequisites to use VMware cluster features successfully.

•	In general, DRS and HA work best if the virtual machines meet VMotion requirements, as discussed in the next section.

•	If you want to use DRS for load balancing, the hosts in your cluster must be part of a VMotion network. If the hosts are not in the VMotion network, DRS can still make initial placement recommendations.
