In this video I will explain what is Resource Pool and how does it work and you will be able to:
- Understand what is a resource pool
- Create a resource pool
- Manage a pool’s resources
Later on we’ll get more detailed into vCenter and how Resource Pools are used to manage Virtual Machines across multiple hosts.
A Resource Pool is a set of resources that we can either set aside or we can limit to a specific virtual server or number of virtual servers.
A Resource pool allows you as the administrator to divide and allocate resources to VMs and other resource pools.
Resource pools are also used to delegate privileges to other users and groups. Every Resource Pool has a name and it’s visible in the vCenterInventory tab. It has associated access control and permissions.
When we’re using single ESX host or multiple ESX hosts but we are not using vCenter Server, our options are fairly limited and administering our ESX server actually is very simple. We’re going to go over a lot of the basic functions that you’ll perform as an ESX server administrator in a situation where you’re not using vCenter Server.
Each Resource pool allows you to define:
- reservation (minimum),
- limit (maximum) and
- share values for both CPU and memory resources.
A resource pool has a parent pool and it may contain child pools or just VMs that are powered on within it. A resource pool allows you to control the aggregate CPU and memory resources of the compute resource, which is either a standalone host or a cluster of physical systems.
