Mode

Two modes are available: advisory and managed. Advisory

 

mode allows you to see what CPU resource requests gWLM

 

would make for a workload—without actually affecting

 

resource allocation.

 

/

 

Advisory mode is not available for SRDs containing virtual

 

machines, psets, or fss groups due to the nature of these

 

compartments.

 

Use this mode when creating and fine-tuning your policies.

 

Once you are comfortable with your policies, use managed

 

mode to have gWLM automatically adjust the resource

 

allocations for your defined workloads.

 

You can only set the mode on the SRD level. All workloads

 

within an SRD operate in the same mode, either advisory

 

or managed.

Deploy

Enable gWLM control of an SRD.

 

Deploying an SRD in managed mode enables gWLM control

 

of resource allocation within the SRD. For example, in an

 

SRD based on a vPar that has psets for compartments,

 

deploying an SRD in managed mode allows gWLM to

 

actively migrate cores among psets. (A core is the actual

 

data-processing engine within a processor. A single

 

processor might have multiple cores.)

 

When deploying an SRD in advisory mode, gWLM simply

 

reports what the allocation would be—without actually

 

affecting resource allocations on a system.

 

Advisory mode is not available for SRDs containing virtual

 

machines, psets, or fss groups due to the nature of these

 

compartments.

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.
