![]() ![]() Normally, the host/cluster is the Provider and the VMs are the Consumers. You can meet provider-consumer terminology explaining Resource Pools, e.g. DRS is available in vSphere Enterprise and Enterprise Plus editions. To configure Resource Pools you need to enable VMware Distributed Resource Scheduler (DRS) on a cluster. The resource pool resources are then available to child resource pools and virtual machines. Resource Pool is similar to a folder (possibility to specify permissions) but not the same, why? For each resource pool, you can specify reservation, limit, shares, and whether the reservation should be expandable. If you do not create child resource pools, only the root resource pools exist. The cluster (Tokyo-cluster) itself represents the root resource pool. Resource pools and virtual machines that are at the same level are called siblings. The resource pools at a higher level are called parent resource pools. You can create a hierarchy of shared resources. As shown in above figure, a resource pool can contain child resource pools, virtual machines, or both.
