Concurrent Operations Limits for vCenter Server and View Composer
When you add vCenter Server to Horizon 7 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 and View Composer.
You configure these options in the Advanced Settings panel on the vCenter Server Information
page.
Table 2-1. Concurrent Operations Limits for vCenter Server and View Composer
Setting Description
Max concurrent vCenter
provisioning operations
Determines the maximum number of concurrent requests that 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 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 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 full virtual machines and linked clones.
Max concurrent View
Composer maintenance
operations
Determines the maximum number of concurrent View Composer refresh, recompose,
and rebalance operations that can take place on linked clones managed by this View
Composer instance.
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 linked clones only.
Max concurrent View
Composer provisioning
operations
Determines the maximum number of concurrent creation and deletion operations
that can take place on linked clones managed by this View Composer instance.
The default value is 8.
This setting applies to linked clones only.
Setting a Concurrent Power Operations Rate to Support Remote
Desktop Logon Storms
The Max concurrent power operations setting governs the maximum number of concurrent
power operations that can occur on remote desktop virtual machines in a vCenter Server instance.
This limit is set to 50 by default. You can change this value to support peak power-on rates when
many users log on to their desktops at the same time.
