What are Resource Pools and Why Should You Use Them?
Utilizing virtual machines is a great way to reduce TCO (total cost of ownership). This works by using available computational resources as efficiently as possible. For example, hosting a web server on a computer by itself will only use a fraction of the computational resources available on that computer. On the other hand, by moving that webserver to a virtual machine, and hosting multiple virtual machines on that computer, IT professionals can use as much of those computational resources as possible. On the other hand, IT professionals need to ensure that they don't try to use more resources than a computer can offer. This is why virtual machine hosts use resource pools.
Think of a resource pool like a folder. That folder organizes virtual machines and also belongs to a host computer. The resource pool is more than a folder though. It uses policies to be able to tell the virtual machines organized within it how much memory and CPUs they can use among other things. This ensures VMs don't try to use more resources than a physical computer can offer.
