Virtual servers running on VMware compute resources are managed almost the same as normal virtual servers. The only difference is that publishing rules are used instead of firewall rules and backups are replaced by snapshots. Also, as the VMware 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 VMware:

  • Reboot in recovery
  • Segregate
  • VIP status
  • Autoscaling
  • Migrate VS. VMware utilizes vMotion to ensure that the VSs are optimally placed on the compute resources
  • Backups. Backup process for VMware virtual servers differs from the standard OnApp backup scheme. See VMware VS Snaphots section for details. 
  • Firewall for VMware VSs is presented with publishing rules. See Publishing Rules section for details.
  • It is not possible to gather IOPS statistics for VMware virtual servers.
  • Use of IPv6 is not supported for VMware virtual servers. 


NOTE: Performing the following VS operations at vCenter may lead to performance inconsistencies. Please, do not execute the following actions in vCenter:

  • Power VSs ON and OFF
  • Pause and Unpause VSs
  • Edit the Properties for any VS
  • Create and delete Snapshots
  • Make changes to the distributed VSwitch
  • Remove templates from the data store
  • Rename templates
  • 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
  • No labels
