In this chapter, you learned all about managing vSphere HA and DRS clusters. We looked at retrieving HA master or primary hosts, retrieving cluster configuration issues, and disabling HA, to perform network maintenance that may cause network isolation. You learned about disabling or enabling host monitoring, associating a host profile with a cluster, enabling VM and Application Monitoring, configuring the heartbeat datastore selection policy, moving hosts to clusters, and moving clusters.

Using DRS rules and DRS groups, we discussed how to control the placement of virtual machines on hosts in a cluster. You learned to use resource pools and to divide the resources of the cluster into different pools. We looked at configuring resource allocation between virtual machines, with shares, limits, and reservations.

Finally, you read how to use Distributed Power Management, to save money in power and cooling costs during the periods of low resource utilization.

The following chapter will be about managing vCenter Server.
