HP Hewlett-Packard Cover Letter for: HP Integrity Essentials Global Workload Manager Agent V4.1 for OpenVMS June 2010 Dear Customer, Hewlett-Packard is pleased to introduce the release of OpenVMS Global Workload Manager Agent (gWLM Agent) V4.1 for Integrity server plat- forms. gWLM is the first of the HP Virtualization technologies ported to OpenVMS, offering customers the opportunity to obtain better uti- lization out of their Itanium CPUs. This cover letter discusses the following topics: o OpenVMS gWLM Features o HP gWLM Central Management Server o HP Service Support o Documentation o Software Product Description o OpenVMS gWLM Software Distributions Before installation, please take a look at the Release Notes (provided separately) for the latest information about this release. Features HP OpenVMS Global Workload Manager (gWLM) is a multi-system, multi- OS workload manager with an intelligent policy engine. It is an in- tegral component of the HP Virtual Server Environment (VSE). It in- tegrates with resource management (whole processor and sub-CPU allo- cation mechanisms within a single operating system) and partitioning 30-April-2010 techniques (nPartitions and HP Integrity Virtual Machines) to dynam- ically reallocate resources to applications based on application per- formance or business policy. This improves server utilization while maintaining and monitoring service levels across many servers. gWLM enables customers to set policies that automatically optimize us- age of CPUs within a multi-CPU system, or a group of OpenVMS Integrity systems. This results in: o Improved utilization of Integrity CPUs across multiple work streams o Automatic CPU resource allocation to satisfy Service Level Agree- ments (SLAs) of multiple Business Units, based on IT management de- fined policies OpenVMS Global Workload Manager has been designed for data center en- vironments where a central IT organization is acting as a service provider to internal customers or a Service Provider is allocating compute re- sources to multiple, independent organizations bound by stringent SLAs. gWLM will allow standard resource allocation policies or policies spe- cific to individual customer requirements to be quickly and easily de- ployed across a consolidated, virtualized data center. Please note that gWLM does not move workloads across nodes to a sys- tem that is underutilised. It allocates CPUs to where the demand is within each specific system. HP gWLM Central Management Server To use gWLM with an OpenVMS managed node, the gWLM agent has to be in- stalled and running on the managed node. Each gWLM Agent instance is managed from the HP Global Workload Manager Central Management Server (CMS), which is part of the HP ID-VSE (Insight Dynamics Virtual Server Environment) suite of products. ID-VSE integrates with HP Systems In- sight Manager (SIM). HP SIM is free of charge. HP ID-VSE is a licensed product. 2 OpenVMS managed nodes running the gWLM agent are supported for man- agement with HP SIM 6.0 and HP ID-VSE 6.0 hosted on a Windows Central Management Server (CMS). Please refer the HP Insight Software 6.0 Sup- port Matrix at: http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02048580/c02048580.pdf for details on the Windows CMS configuration. HP SIM and HP ID-VSE are part of HP Insight Software 6.0 DVD Media, which can be obtained from: https://h20293.www2.hp.com/portal/swdepot/try.do?productNumber=ISDVD CMS provides a Web accessible Graphical User Interface (GUI) for man- aging, monitoring, and configuring, from which the system manager or administrator manages gWLM Agents running on multiple OpenVMS systems across the network. The CMS also provides reporting and graphical dis- plays of CPU usage on any selected system or systems as required. HP Service Support and Tools A variety of service options are available from HP. For more infor- mation contact your local HP account representative or distributor.
