Section I: Introduction
In business it’s not the strongest that survive, it’s the most adaptive. To stay competitive, companies must constantly rethink their business processes--and each change requires an IT response. HP’s Adaptive Enterprise strategy synchronizes business and IT to capitalize on change.
Key to achieving an HP Adaptive Enterprise is virtualization—an approach to IT that pools and shares resources so utilization is optimized and supply automatically meets demand.
HP’s virtualization solution for HP Integrity and HP 9000 servers is the HP Virtual Server Environment (VSE). This presentation serves as an introduction to VSE and illustrates the features and benefits of HP Global Workload Manager, the intelligent policy engine that orchestrates VSE.
Section II: VSE & gWLM
HP Virtual Server Environment
The HP Virtual Server Environment is an integrated server solution that delivers a flexible computing environment. With VSE you can:
- Double resource utilization
- Maintain continuous service levels
- Pay only for what you use
VSE encompasses a suite of fully integrated offerings that includes:
- Availability solutions such as clustering and disaster tolerance
- Partitioning solutions such as nPars, vPars, and Resource Partitions
- Utility pricing solutions such as Instant Capacity and Pay Per Use
Each of these solutions is controlled by HP’s automated workload management software. HP Global Workload Manager for HP-UX 11i and Linux is the newest generation of HP’s workload management solutions.
HP Global Workload Manager
As the intelligent policy engine for multi-system Virtual Server Environments, HP Global Workload Manager makes the benefits of virtualization a reality.
Improve resource utilization
HP Global Workload Manager helps improve resource utilization by providing IT with the tools to monitor workloads and assign resources as needed.
Enable a centralized IT infrastructure
For companies adopting a more centralized IT infrastructure, HP Global Workload Manager eases the transition by providing automation across multiple systems. Reporting and billing features help build trust and confidence in the process.
For those IT departments already acting as a service provider, HP Global Workload Manager makes sharing resources simple and transparent.
Improve operational efficiency
Learning curves are minimal with HP Global Workload Manager. It’s easy to deploy and manage, and offers out-of-the-box support for many commonly used policies and configurations.
Section III: User Scenarios
HP Global Workload Manager helps centralized IT assign, manage, and reallocate resources to meet changing business demands. The following user scenarios demonstrate how.
Scenario 1: Multiple Workloads in a Utility Environment
In this scenario IT acts as an enterprise service provider within a utility environment. The lines of business are IT customers.
IT consolidates the database systems for each line of business onto shared servers and applies gWLM policies that specify the amount of CPUs each line of business “owns.”
When demand on a database grows it "borrows" CPUs from the idle databases.
When demand on the other databases grows they re-acquire the CPUs.
In circumstances where all databases are busy, each is guaranteed the CPUs it owns.
Scenario 2: Production, Test, and Development Consolidation
In this scenario a user has two servers, and each server has two vPars: a production environment vPar and a test or development environment vPar.
gWLM policies are applied to the production environment vPar of four CPUs and to the test and development environment vPar of two CPUs.
gWLM allocates the resources the production environment requires, and any other resources are consumed by the test and development vPars.
For most of the month, the production environment handles transaction-based workloads, leaving CPUs available for testing and development to borrow as needed.
At month’s end, when the production environment requires additional resources for payroll and other batch workloads, it can borrow CPUs from the testing and development environment.
If the production environments are in an HP Serviceguard cluster and one member fails, HP Serviceguard moves the package to the production vPar on the other server.
The production vPar now has an increased load, and can borrow CPUs from the testing and development environment.
Scenario 3: Oracle 9i RAC
This scenario involves two instances of Oracle configured in a RAC cluster.
Each instance of Oracle belongs to one vPar on two different servers. Each server also contains an additional vPar used for lower priority workloads such as batch or testing and development.
When the database is handling a moderate load, both instances might only consume one CPU. The remaining CPUs would support the other vPars.
If one of the instances fails, the load on the remaining instance increases dramatically. When this happens, gWLM responds by increasing the number of CPUs available to the healthy instance.
When the failing instance is brought back online, gWLM responds by returning the borrowed CPUs.
Section IV: Using HP gWLM
HP Global Workload Manager provides quick time-to-value with a Discovery and Configuration Wizard and out-of-the-box support for common policy and reporting configurations.
The Web-based user interface makes it easy for IT to manage workloads, assign policies, and monitor usage.
The gWLM home page is a great starting point for first-time users.
Configuring gWLM to manage multiple workloads is accomplished in four simple steps:
- Enter the system where workloads will be managed.
- Select the workloads to add.
- Associate a policy with each workload.
- Review and confirm.
Reporting provides valuable data for the system administrator.
Real-time workload and policy reports allow administrators to view CPU utilization and allocation data.
Audit reports provide business units with the assurance that they’re receiving the services they paid for.
Section V: Why HP VSE & HP gWLM
Business is entering an era where new approaches to IT are required to maintain a competitive edge. With the HP Virtual Server Environment and HP Global Workload Manager, your company can become a more Adaptive Enterprise.
By providing IT with the tools to improve resource utilization, the ease-of-use needed to maintain continuous service levels, and the reporting to facilitate internal utility pricing options, HP Global Workload Manager helps business deliver on the needs of tomorrow.
