A resource pool is a logical abstraction of resources from the root, the root being a standalone ESXi host or a DRS-enabled cluster. The Distributed Resource Scheduler (DRS) feature is used to load balance virtual machines across a cluster based on CPU and memory utilization. DRS is discussed further in Chapter 9, Balancing Resource Utilization and Availability. These resource pools are managed hierarchically using a parent-child relationship. Resource pools divide and allocate resources to virtual machines, child resource pools, or vApps.
Organization: Resource pools are created and organized hierarchically and resource allocations are modified as needed.
Separation of resources from hardware: This is a good thing. Resource management can be performed independently of the cluster and ESXi hosts that are contributing the resources. This will allow for more aggregate computing capacity and less worry regarding the individual ESXi hosts. This allows for...
