HP-UX 11i Version 2 May 2005 Release Notes
General System Administration
HP Partitioning
Chapter 5
102
On HP-UX managed nodes, gWLM can manage workloads based on nPartitions (that
use Instant Capacity), virtual partitions, processor sets, or fss groups. On Linux,
gWLM manages workloads based on processor sets (created using CPU affinity
masks).
• Agent LTU (T2762AA on HP-UX; T2778AA on Linux)
The agent is free. However, it is functional only for a limited time. For unlimited use,
purchase and install the agent License To Use (LTU) for each managed node.

Impact
The benefits of gWLM include the following:
• Better use of the server capacity you already have
Typically, servers are set up with a single workload and ample reserve capacity to
handle the peak demand of that workload. gWLM allows you to combine multiple
workloads on a single server and make use of the reserve capacity—when it is not
needed by your mission-critical workload.
• Confidence that your mission-critical workloads get the resources they need
Even with multiple workloads on a server, you can ensure your mission-critical
workload gets the resources it needs: gWLM automatically adjusts resource
allocation, making it easy to share resources when they are plentiful, but also to
dedicate those resources to workloads when there are spikes in resource demand.
• Reduced system administration costs
With gWLM managing resource allocation, you can combine more workloads on
fewer servers, reducing administration costs.
Compatibility
There are no known compatibility issues.
Performance
gWLM improves performance system utilization when properly configured.
