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. The CMS is not available on HP-UX 11i v3. However, you can use a CMS on other systems (running HP-UX 11i v1 or HP-UX 11i v2) to control HP-UX 11i v3 managed nodes.
Trial 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. (Agents on HP-UX 11i v3 do not support Hyper-Threading enablement or online cell operations.)
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. (Up to 1024 fss groups are supported.) 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

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

Since September 2005, gWLM has been updated to version A.02.50.00.x.

The following changes occurred at version A.01.01.02:

gWLM now assumes a constant size for each shared resource domain
License agreement is displayed when you first run the gWLM agent
gWLM history truncation deletes configuration data in addition to historical data
HP-UX Systems running the gWLM agent only need the JRE (The JDK is no longer needed.)

The following changes occurred at version A.02.00.00.x:

gWLM is now part of the HP Virtual Server Environment (VSE) Management Software
gwlminitconfig was replaced by vseinitconfig
The gWLM CMS bundle (T2412AA) is no longer available; instead, use the VSE CMS bundle (VSEMgmt)
gWLM can now manage virtual machines created using the HP Integrity Virtual Machines software
gWLM can take advantage of Temporary Instant Capacity
All policy types can now be combined in a single shared resource domain (SRD)
OwnBorrow policy: weight value now defaults to the “owned” value—unless you explicitly give a weight value
Valid names have been expanded to include a colon and start with a number
The “Manage Workloads” wizard and “Unmanage Workloads” wizard have been integrated into the new Manage Systems and Workloads wizard
Support for mixed-architecture servers
Compatibility with OpenVMS
Resources are now allocated in the following order to satisfy:
1. Compartment minimum values (without regard to priority)
2. Policy minimum values (without regard to priority)
3. Requests that are less than a policy’s owned value (without regard to priority)
4. Requests that are less than a policy’s maximum value (based on priority)
5. Policy maximum values
6. Compartment maximum values
High availability behavior when non-master loses communication was modified
Host-based authorizations
New reports available through gwlmreport: abnormal utilization report; extract report to collect data for use with OpenView Performance Agent (OVPA)
Reports from gwlmreport available through HP Systems Insight Manager (SIM)
New gwlmreport extract options (--columnhelp, --columns, --datestamps)
--outputpath now available with the resourceaudit and topborrowersreports from gwlmreport to specify the path for report output
New gwlm export --all option to export the entire configuration repository with a single command
Changed behavior for gwlm history --truncate=CCYY/MM/DD

The following changes occurred at version A.02.50.00.x:

Support for Linux managed nodes
Support for Windows virtual machine guests
Nested partitions
Default interval differs based on the type of compartment being managed
Convergence rate now applies to OwnBorrow and utilization policies
gwlmreport config command generates a report showing the history of configuration changes
Changes to gwlm command
New gwlm license --host option
New gwlm history --purge option
New gwlm subcommands
- gwlm agentinfo
- gwlm reset
New gwlm monitor --nested option
gwlm manage --id option is no longer required
Automated security certificate distribution
Treatment of Temporary Instant Capacity (TiCAP) resources has been modified
User-configurable log file size and number of log files
Advisory mode no longer available for psets and fss groups
