Resource Management Objects

Central to resource management for all environments is either a
ComputeResource
 or a
ClusterComputeResource
 managed object.
  • The
    ComputeResource
     managed object represents the set of resources for a set of virtual machines. A
    ComputeResource
     is always associated with a root
    ResourcePool
     object, representing the resources of a single host.
  • The
    ClusterComputeResource
     data object aggregates the compute resources of multiple associated
    HostSystem
     objects into a single compute resource for use by virtual machines. A
    ClusterComputeResource
     is associated with a root
    ResourcePool
     representing the combined resources of the cluster. If you plan on using VMware cluster services such as HA (High Availability), DRS (Distributed Resource Scheduling), or on using EVC (Enhanced vMotion Compatibility), use
    ClusterComputeResource
    .
    HA, DRS, and EVC may require feature licenses. If any clustering functionality does not work properly, check whether you have licenses for it.
  • The
    ResourcePool
     managed object represents a set of physical resources of a single host, a subset of a host's resources, or resources spanning multiple hosts. Resource pools can be subdivided by creating child resource pools. Only virtual machines associated with a resource pool can be powered on.
