Change server load management policy settings

Feb 27, 2013

Server OS machine policies determine which settings calculate server load.

Note: This release does not support the XenApp Load Evaluator setting created for XenApp 6.5.

The default Load Management settings work for most Server OS machine environments. However, if you want to change these settings, policies are available to adjust loading. See Load Management policy settings.

Servers delivering Server OS machines have default load management settings to make sure that sessions are balanced between servers. Use the Load Management policy to change the following settings.

Note: A value of -1 for any of the following settings indicates this setting is excluded from load calculation.
