Objects in Vcenter


Some of the objects we come across in Vcenter which are listed and their functionalities are in brief. I have only highlighted the core points of these objects and there may be other functions too.

1. Folders: Can contain any object, or groups of objects.

  • Allows for logical organization of objects based upon any desired criteria
  • Permissions and alarms can be defined for contained objects

2. Datacenters: For most intents and purposes, this is the root of an environment. Hosts, clusters, VMs, vApps, and Resource Pools all aggregate to a datacenter.

  • IP Pools(DNS, DHCP, IP Ranges)
  • Only Object to appear in all views(Host and Cluster, VM and Templates, Datastores, Networking), besides the vCenter Server.

3. Clusters: Groups of hosts used for collective resources management.

  • High Availability
  • Distributed Resource Scheduler

4. Resource Pool: Manages allocated resources to child objects

  • VMs use memory and CPU that has been allocated to the Resource Pool
  • Limits, Shares and Expandable Reservations

 

5. vApp: Is a hybrid between a VM and a Resource Pool.

  • Can be migrated, turned on/off
  • VMs use memory and CPU that has been allocated to the vApp
  • IP Pools(DNS, DHCP, IP Ranges)
  • Designate start(boot) order for child objects
  • Limits, Shares and Expandable Reservations
