Resource pool hierarchies allow detailed control over which virtual machines are allowed how many resources, by dividing resources between children at each level of the hierarchy. Child resource pools can be configured with reservations and limits, similar to virtual machines. Child resource pools can also be configured with shares settings, which take effect in resource contention situations.

For more information about how reservations and limits apply to resource pool hierarchies, see Configuring Reservation and Limit for Resource Pools. For more information about how shares apply to resource pool hierarchies, see Configuring Priority Shares for Resource Pools.
