Power and Capacity Management

Oct 09, 2015

Citrix XenApp Power and Capacity Management can help reduce power consumption and manage XenApp server capacity by dynamically scaling up or scaling down the number of online XenApp servers. Consolidating sessions onto fewer online servers improves server utilization, while providing sufficient capacity to handle load while minimizing unnecessary power consumption.

As users log on to the system and reduce the idle capacity (how much capacity is available for additional sessions), other servers in the workload are powered up. As users log off and idle capacity increases, idle servers are shut down. This helps optimize capacity for XenApp workloads.

Scheduling provides an automated approach. An administrator defines specific times for powering on and powering off workloads. For example, a schedule powers on servers at 8 a.m. and powers them down at 7 p.m. from Monday through Friday.

Load consolidation and power management operate in unison; load consolidation ensures sessions are not spread across online servers, which provides a better opportunity to power off excess servers later, using power management.

The administrator can manually override capacity and schedule settings to accommodate unexpected changes in demand.

Metrics are collected for system usage reports.

Power and Capacity Management respects all configured XenApp server settings, farm settings, and policies.
