HP Global Workload Manager
HP Global Workload Manager (gWLM), a component of the HP Virtual Server
Environment (VSE) Suite, 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. In addition, gWLM provides both
real-time and historical monitoring of the resource allocation. gWLM has three
components:
• VSE Central Management Server, or CMS (VSEMgmt)
You can obtain the VSEMgmt bundle from http://hp.com/go/softwaredepot. It is
not available on the Operating Environments (OE) or Application Release (AR)
media.
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 5.x
installed.
• Agent (T2743AA)
The gWLM agent is default-installed on the OE media and is also available from the
AR media.
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 HP-UX
managed nodes, you place each workload in an nPartition (npar), a virtual partition
(vpar), a virtual machine (created using HP Integrity Virtual Machines), a processor
set (pset), or an fss group. On Linux managed nodes, you place each workload in a
pset (created using a CPU affinity mask.) gWLM manages your workloads by
controlling the resource allocations to the npars, vpars, virtual machines, psets, or
fss groups.
• License to Use, or LTU (T2762AA)
You can obtain the CMS and the agent free of charge. The A.02.50.00.x agent works
for a period of 120 days. After the 120 days, the agent:
— Cannot be restarted once it is stopped
— Refuses changes to deployed SRD configurations
— Refuses to deploy new SRD configurations
To continue using gWLM agents after a free-use period has ended, you must install a
license on each managed node. This license is available on the AR media. It is also
available as part of the VSE LTU (T2786AC), which enables you to use gWLM and
all the other components of the VSE suite.
Summary of Change
gWLM A.02.50.00.x provides the following changes and new features:
• Enables you to nest partitions, such as fss groups inside vpars, with gWLM
managing resources for all the partition types
• Ability to display and compare previous configurations
• Can use Java JRE/JDK 1.4.2 or Java 1.5 (5.0)
• Support for managed nodes running Linux
