Software Product Description ___________________________________________________________________ PRODUCT NAME: HP Integrity Essentials Global Workload Manager Agent V4.1 SPD 82.39.01 DESCRIPTION HP Integrity Essentials Global Workload Manager (gWLM) for OpenVMS is a multi-system, multi-OS workload manager with an intelligent policy engine. It is an integral component of the HP Virtual Server Environ- ment (VSE). It integrates with resource management (whole processor and sub-CPU allocation mechanisms within a single operating system) and partitioning (nPartitions and HP Integrity Virtual Machines) tech- niques to dynamically reallocate resources to applications based on application performance or business policy. This improves server uti- lization 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 Better use of existing server capacity. o Automatic CPU resource allocation to satisfy Service Level Agree- ments of multiple Business Units, based on Information Systems man- agement defined policies. Improving and optimizing CPU usage typically results in: o A lower cost solution than purchasing additional CPUs to satisfy increasing work load demands. o As workloads grow, gWLM restricts the escalation of hardware main- tenance, service, operating system, floor space, electricity and air conditioning costs. June 2010 o Reduced 3rd Party software costs as CPU count is kept to a mini- mum. 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 underutilized. It allocates CPUs to where the demand is within each specific system. gWLM makes use of the iCAP software to manage CPU resources across nPar- titions within an HP cell-based system. gWLM controls CPU resource al- location to nPartitions by using the iCAP software to satisfy usage right restrictions and/or to use Temporary Instant Capacity (TiCAP). The CPU resources are activated or deactivated in nPartitions based on priority and need. OpenVMS gWLM Concepts CompartmentAn nPartition, a virtual machine provided by HP In- tegrity Virtual Machines (HPVM), a Processor Set, or a Fair Share Scheduler (FSS) group (a.k.a Class Scheduler group) with its resource allocation being managed by gWLM. Workload The collection of processes executing within a single compartment. Shared A collection of Compartments among which CPUs can be Re- shared. source Domain 2 Policy Tells gWLM when to reallocate CPUs and how much to give each workload. The Administrator applies a specific policy to each workload and gWLM monitors each workload, estimates CPU demand and reallocates CPUs ac- cordingly. After configuration, the managed nodes operate autonomously with performance data stored on each node, that is sent to CMS peri- odically. Real-time reporting from any node may also be specified. 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 gWLM 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 Insight Manager (SIM). HP SIM is free of charge. HP ID-VSE is a licensed product. OpenVMS managed nodes running the gWLM agent are supported for man- agement with HP SIM 6.0 and ID-VSE 6.0 hosted on a Windows Central Man- agement Server (CMS). For details on the Windows CMS configuration, see the HP Insight Soft- ware 6.0 Support Matrix at: http://bizsupport2.austin.hp.com/bc/docs/support /SupportManual/c02048580/c02048580.pdf 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 Integrity systems across the network. The CMS also provides multiple reporting 3 and graphical displays of CPU usage on any selected system or systems as required. User Roles and Authorizations HP SIM allows defining user roles with different toolbox authoriza- tions. Users can be authorized in HP SIM to run the ID-VSE for Integrity tools. Following are the toolboxes associated with gWLM. VSE All Tools This toolbox can be authorized on managed systems to allow users to view and manage those systems using gWLM. VSE Monitor ID-VSE for Integrity users should have this authorization on the CMS and All Managed Systems. This toolbox allows a view-only use of gWLM on managed systems. For more information on ID-VSE user roles and authorizations, see the HP Insight Dynamics VSE 6.0: Integrity CMS Installation and Config- uration Guide at: http://h20000.www2.hp.com/bc/docs/support /SupportManual/c02046075/c02046075.pdf Discovery gWLM will discover entities that are capable of being a resource do- main by discovering the entity type, hostname, IP address and whether the gWLM Agent is installed. If gWLM discovers a system with the gWLM Agent installed and running, it will fully discover the system includ- ing all containers in the resource domain, flexing capabilities. 4 Resource Management gWLM monitors CPU resource consumption so it can adjust an applica- tion's CPU allocation when necessary to meet certain performance cri- teria. It does this on a continual basis and feeds that information to the gWLM arbitration module that will automatically adjust the CPU resources allocated to the container that hosts the application. The CPU resources are adjusted based on the resource allocation pol- icy. This policy may be either a performance goal for an application, or a resource utilization policy indicating how much of a resource is needed. A priority is also associated with the policy to arbitrate re- sources among multiple applications. OpenVMS gWLM Capabilities: o Manage OpenVMS Integrity server instances and load balancing, Pro- cessor Sets, and Class Scheduler groups on OpenVMS. o Discovery of resource partitions. o CPU resources can be guaranteed.

Software Alpha to Integrity Trade-in Licenses: OpenVMS gWLM qualifies for the standard Alpha to Integrity trade-in policy as customers move to the OpenVMS Integrity platform. For customers on support there is a 100% credit and the relevant part number is BA447BCN#201. Note: If a customer moves from a gWLM OpenVMS Alpha system with a max- imum CPU count less than the target gWLM Integrity system, this credit is only valid on the number of CPUs supported on the original Alpha system. E.g. Original AlphaServer ES47 (4 CPUs max.) gWLM license traded for an rx7620 Integrity system (8 CPUs max.). The gWLM license traded will only license four CPUs within the rx7620. Additional gWLM Integrity 9 Per Processor Licenses must be purchased for all CPUs in excess of four installed in the rx7620.
