vCenter Virtual Servers

Virtual servers running on vCenter compute resources are managed almost the same as normal virtual servers.  Also,  the vCenter cluster is displayed as a pool of resources rather than per compute resource.

OnApp Cloud gives you high-end cloud management features including:

 Certain VS operations are unavailable in OnApp with vCenter:

  • Reboot in recovery
  • Segregate 
  • VIP status
  • Autoscaling
  • Migrate VS. vCenter utilizes vMotion to ensure that the VSs are optimally placed on the compute resources. However, you can migrate vCenter virtual servers to KVM
  • Backups. Backup process for vCenter virtual servers differs from the standard OnApp backup scheme. See vCenter VS Snaphots section for details. 
  • Use of IPv6 is not supported for vCenter virtual servers.  

NOTE: Performing the following VS operations at vCenter may lead to problems with VMware infrastructure management. Please, do not execute the following actions in vCenter:

  • Edit the Properties for any VS
  • Create and delete Snapshots
  • Make changes to the distributed vSwitch
  • Remove templates from the data store
  • Delete the services account on the virtual server
  • Remove or stop VMware tools on the virtual server

Performing the following actions in vCenter will not affect OnApp:

  • Migrate VSs between compute resources using vMotion
  • Migrate VSs between data stores using Storage vMotion
  • Place compute resources into maintenance mode
  • Make changes to compute resources when in maintenance mode
  • Back up VSs using third party tool (e.g. Veeam)
  • Enable, Disable or make changes to DRS

Performing the following actions in vCenter will be synchronized with OnApp:

  • Networks Created
  • Networks Deleted
  • Datastores Created
  • Datastores Deleted
  • New Compute Added
  • Compute Remove
  • Updates to Imported VSs (Ex. Changed Resources, added NICs, add Disks)
  • VS has been Deleted
