Resource pools are used for the flexible management of CPU and memory resources. Administrators can group them into hierarchies to partition the available resources hierarchically.
In this sense, resource pools can be considered as not only resource providers, distributing resources to virtual machines and child pools, but also resource consumers, consuming parents' resources either from parent pools or from clusters and hosts directly.
One of the main advantages of resource pools is the ability to manage all available resources independently from existing hosts and clusters. By assigning VMs to a resource pool, administrators are able to control resource allocation to the set of virtual machines rather than per VM. This eliminates the need to set resource allocations and limits for each virtual machine.
Resource pools can be very useful when you need to manage a set of servers with different requirements for CPU and memory availability. For example, servers with high...
