Explanation:

Using resource pools can result in the following benefits:
– Flexible hierarchical organization. You can add, remove, or reorganize resource pools or change resource allocations as needed.
– Isolation between pools, sharing within pools . Top-level administrators can make a pool of resources available to a department-level administrator. Allocation changes that are internal to one departmental resource pool do not unfairly affect other unrelated resource pools.
– Access control and delegation. When a top-level administrator makes a resource pool available to a department-level administrator, that administrator can then perform all virtual machine creation and management within the boundaries of the resources to which the resource pool is entitled by the current shares, reservation, and limit settings. Delegation is usually done in conjunction with permissions settings, which are discussed in the Introduction to Virtual Infrastructure.
– Separation of resources from hardware. If you are using clusters enabled for DRS, the resources of all hosts are always assigned to the cluster. That means administrators can perform resource management independently of the actual hosts that contribute the resources. If you replace three 2GB hosts with two 3GB hosts, you don’t need to make changes to your resource allocations. This separation allows administrators to think more about aggregate computing capacity and less about individual hosts.
– Management of sets of virtual machines running a multi-tier service. You don’t need to set resources on each virtual machine. Instead, you can control the aggregate allocation of resources to the set of virtual machines by changing settings on their enclosing resource pool.
