Which statement is true about running both DRS and VMware HA (HA) on the same cluster?
This is not a recommended configuration.
After a host failure, HA will restart virtual machines and DRS will migrate them to balance the workloads.
After a host failure, HA can start virtual machines intelligently using DRS algorithms.
There is no advantage to running these two technologies on the same cluster as they are completely unrelated.
VMware HA is a reactive system, reacting to host failures, DRS is a proactive solution, and gives you better utilization for running VMs by balancing the cluster. After a host failure, HA will restart virtual machines and DRS will migrate them to balance the workloads. Resource Management GuideUnderstanding VMware HAVMware HA Features: A cluster enabled for HA: Is fully integrated with DRS. If a host has failed and virtual machines have been restarted on other hosts,DRS can provide migration recommendations or migrate virtual machines for balanced resource allocation. If one or both of the source andtarget hosts of a migration fail, HA can help recover from that failure.
