Workload Balancing Overview

Workload Balancing is a XenServer appliance that balances your pool by relocating virtual machines onto the best possible servers for their workload in a resource pool. For example, Workload Balancing can:

Balance virtual-machine workloads across hosts in a XenServer resource pool
Determine the best host on which to start a virtual machine
Determine the best host on which to power on a virtual machine that you powered off
Determine the best host for each of the host’s virtual machines when you put that host into Maintenance mode

Note:

Workload Balancing is available for XenServer Enterprise Edition customers, or those who have access to XenServer through their Citrix Virtual Apps and Desktops entitlement. For more information about licensing, see About XenServer Licensing.

Depending on your preference, Workload Balancing can accomplish these tasks automatically or prompt you to accept its optimization, consolidation, and placement recommendations. You can also configure Workload Balancing to power off hosts automatically during periods of low usage (for example, to save power at night).

Workload Balancing evaluates the utilization of virtual-machine workloads across a pool and, when a host reaches one of its thresholds, relocates the virtual machine to a different host in the pool.

To ensure the rebalancing and placement recommendations align with your environment’s needs, you can configure Workload Balancing to optimize workloads for resource performance or to maximize density. These optimization modes can be configured to change automatically at predefined times or stay the same at all times. For additional granularity, you can fine-tune the weighting of individual resource metrics (CPU, network, memory, and disk).

To help you perform capacity planning, Workload Balancing provides historical reports about host and pool health, optimization and virtual-machine performance, and virtual-machine motion history.
