Table 1 Default weights by policy type (continued)

Policy type

Default weight

(You cannot deploy an SRD where all the workloads with fixed policies are not satisfied.)

Utilization

1

OwnBorrow

Equal to its owned value

Custom

1

NOTE: To ensure CPU resource allocations behave as expected for OwnBorrow policies, the sum of the CPU resources owned cannot exceed the number of cores in the SRD. (However, if the sum is less than the number of cores in the SRD, the excess is distributed to all compartments in proportion to the amounts owned. Thus, workloads will routinely get more than they are due.)

Available interfaces

There are two interfaces for controlling and monitoring gWLM:

•Systems Insight Manager

A web-based interface accessed through the Shared Resource Domain tab reached through the Tools→HP Matrix OE visualization... menu in Systems Insight Manager (access Systems Insight Manager via the URL http://hostname:280 where hostname represents the name of your Virtual Server Environment Management Software CMS).

To orient with gWLM, see the gWLM Home page. To view the gWLM Home page, select Tools→HP Matrix OE visualization... from the System Insight Manager menu bar. Then from the HP Matrix OE visualization menu bar, select

Tools→Global Workload Manager→Getting Started - gWLM Home…

(The System Insight Manager menu bar and HP Matrix OE visualization menu bar are discussed in the section “Tabs and menus” (page 17).)

•gwlm command

A command-line interface, described in gwlm(1M) .

Other components of the command-line interface are: vseinitconfig(1M), gwlmcmsd(1M), gwlmagent(1M), gwlmreport(1M), gwlmplace(1M), gwlmsend(1M), gwlmsslconfig(1M), gwlmstatus(1M), and gwlmxml(4).

Assumptions

It is assumed that you have already installed the following software:

•HP Systems Insight Manager

•HP Matrix Operating Environment Management Software CMS

•gWLM agent on your managed nodes

For information about setting up System Insight Manager, see the documentation available at http://www.hp.com/go/hpsim.

The following steps give an overview of the System Insight Manager installation process. When you install the Matrix OE Management Software and gWLM, you must do the following:

1.Decide which system will be your central management server (CMS), then install the Matrix Operating Environment Central Management Server on that system.

This system must also have System Insight Manager installed and running.

UX 11i Workload Management (gWLM/WLM) Software specifications

HP-UX 11i Workload Management (gWLM/WLM) software is an integral component of HP's premier UNIX operating system, designed to enhance system performance and resource management across diverse workloads. This advanced tool allows system administrators to monitor, control, and allocate resources effectively to achieve optimal performance, reliability, and service levels in enterprise environments.

One of the main features of gWLM/WLM is its ability to classify workloads and manage them according to specific policies set by the administrator. By using service level objectives (SLOs), administrators can define the performance criteria for various applications and workloads. gWLM continuously tracks these workloads, ensuring that they adhere to the defined SLOs, thus maintaining a high level of application performance.

The software employs resource pools, which segment resources such as CPU, memory, and I/O bandwidth among different workloads based on predefined priorities. This capability ensures that critical applications receive the resources they require, even during peak usage periods, thereby preventing resource starvation that could lead to system slowdowns or crashes.

Another significant characteristic of gWLM/WLM is its real-time monitoring and reporting capabilities. The software provides detailed insights into resource utilization, workload performance, and system health. Administrators can access this information through a user-friendly interface, allowing for informed decision-making and proactive management.

Integration with HP Serviceguard adds another layer of functionality, enabling high availability for critical applications. gWLM can orchestrate workload migration to ensure that service levels are maintained, even in the event of hardware failures or resource contention.

The technology behind gWLM/WLM is built on advanced algorithms that leverage historical data and predictive modeling to optimize resource allocation dynamically. This means that as workloads change, the system can automatically adjust resource distribution to meet performance targets without the need for constant manual intervention.

gWLM also supports integration with various enterprise management tools, enabling administrators to implement comprehensive monitoring and management strategies across the IT infrastructure. The scalability of gWLM allows organizations of all sizes to benefit from its robust workload management features, ensuring that they can adapt to changing demands in their operational environments.

In summary, HP-UX 11i Workload Management software offers a sophisticated solution for optimizing resource utilization, managing workloads effectively, and maintaining high performance in complex enterprise environments. Its comprehensive features and technologies make it an essential tool for any organization seeking to enhance their IT operations.
