HP Global Workload Manager
HP Global Workload Manager (gWLM) is a tool that allows you to centrally define
resource-sharing policies that you can use across multiple HP servers. These policies
increase system utilization and facilitate controlled sharing of system resources.
gWLM's monitoring abilities provide both real-time and historical monitoring of the
resource allocation.
gWLM A.01.01. x has two components:
• Central Management Server, or CMS (T2412AA)
You configure gWLM and monitor your workloads on the system where the CMS
software is installed. This system must also have HP Systems Insight Manager
1
installed.
• Agent (T2743AA)
You can install the gWLM agent software on each system where you have workloads
you want gWLM to manage. These systems are known as managed nodes.
On managed nodes, you define workloads based on:
— nPartitions with Instant Capacity installed
— Virtual partitions (vpar)
— Processor sets (pset)
—fss groups
gWLM manages your workloads by controlling the resource allocations to the npars,
vpars, psets, or fss groups.
Summary of Change
In September 2005, gWLM is shipping for the first time on the HP-UX 11i v1 Operating
Environments. (In December 2004, gWLM A.01.00 was delivered on the HP Software
Depot at http://www.hp.com/go/softwaredepot.)
Impact
The benefits of gWLM A.01.01. x 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
