When you add vCenter Server to Omnissa Horizon 8 or edit the vCenter Server settings, you can configure several options that set the maximum number of concurrent operations that are performed by vCenter Server.
You configure these options in the Advanced Settings panel on the vCenter Server Settings page in the Add vCenter Server wizard.
| Setting | Description |
|---|---|
| Max concurrent vCenter provisioning operations | Determines the maximum number of concurrent requests that Omnissa Horizon Connection Server can make to provision and delete full virtual machines in this vCenter Server instance. The default value is 20. This setting applies to automated pools of full virtual machines only. |
| Max concurrent power operations | Determines the maximum number of concurrent power operations (startup, shutdown, suspend, and so on) that can take place on virtual machines managed by Horizon Connection Server in this vCenter Server instance. The default value is 50. For guidelines for calculating a value for this setting, see Setting a Concurrent Power Operations Rate to Support Remote Desktop Logon Storms. This setting applies to automated pools of full virtual machines. |
| Max concurrent maintenance operations | Determines the maximum number of concurrent maintenance operations that can take place. The default value is 12. Remote desktops that have active sessions must be logged off before a maintenance operation can begin. If you force users to log off as soon as a maintenance operation begins, the maximum number of concurrent operations on remote desktops that require logoffs is half the configured value. For example, if you configure this setting as 24 and force users to log off, the maximum number of concurrent operations on remote desktops that require logoffs is 12. This setting applies to instant clones. |
| Max concurrent Instant Clone Engine operations | Determines the maximum number of concurrent creation and deletion operations that can take place on instant clones managed by this vCenter Server instance. This setting applies to instant clones only. |
