Introduction In 2010, HP introduced a new line of Integrity servers, entry-class to high-end. The new servers based on HP’s Converged Infrastructure strategy, attack IT sprawl with a standards-based, modular bladed architecture that also includes common components and a common management environment for all HP servers. The result is a set of servers that are modular, modern, and easier to manage than ever before.

This document is targeted to those customers interested in using virtualization on the new HP Integrity servers. This white paper highlights some common usage scenarios using the different HP-UX virtualization technologies on these servers, and points elsewhere for more information.

Issues customers face with the inefficiencies and complexities of their server environment Historically, new applications were implemented on additional, individual servers to minimize the impact to performance and availability to existing applications. These new boxes were configured with enough capacity to handle the peak requirements of the application with room for growth. Often, however, these peak periods are seasonal and last for short periods of time (e.g. month or quarter end, and Christmas holiday). Multi-tiered applications (database tier, application tier, client/Web tier) were deployed on multiple servers to optimize the performance of each tier. Development, test and production environments were usually isolated on separate servers to avoid negative impact.

The result of these factors has been server sprawl. Many data centers are now encumbered with challenges around: floor space, cabling, power and cooling, networking, management and general complexity and inflexibility. In addition, there are too many isolated and underutilized servers, and cost structures are high and unpredictable.

Why customers are interested in virtualization and consolidation Faced with ongoing cost and efficiency pressures, many enterprises seek to reduce IT costs by tackling the inefficiencies and complexity of their legacy IT infrastructures. One of the major challenges facing these organizations is to manage these diverse workloads while achieving the most effective use of their computing assets to reduce TCO. As a result, organizations now look to deploy multiple new applications onto few servers, or consolidate the existing number of systems, using virtualization.

Implementing an effective infrastructure for enterprise business applications in today’s dynamic, virtualized environment presents a number of challenges for enterprises and service providers. Most organizations, especially in today’s economy, need a well-designed IT infrastructure that:

• Provides high levels of: service, availability, server utilization, performance, application isolation, flexibility, and automation at a reasonable cost

• Supports high fluctuation of traffic and demands • Rapidly deploys, grows, shrinks, and changes server environments in line with constantly changing

business requirements • Provides access to the precise capacity they need at any point in time, but flexible enough to keep

that capacity separate from the capacity utilized by other customers. • Supports fastest time-to-market for new services

While each of the examples in this white paper could have also been accomplished with multiple servers, virtualization best addresses these issues and requirements.

How HP’s Converged Infrastructure provides the ideal mission-critical platform for consolidation The HP Converged Infrastructure is the HP Enterprise Business strategy and portfolio to help businesses overcome these challenges of IT sprawl and to help shift resources from operations to innovation. HP’s Converged Infrastructure provides a next-generation data center blueprint specifically designed to eliminate costly IT and application silos. This is accomplished by integrating and automating technologies into shared pools of interoperable resources, aligned with business processes.

The new Integrity servers for HP Converged Infrastructure are the ideal mission-critical platform for consolidation of data bases, enterprise business applications, disaster recovery servers and legacy servers, a proven approach for reducing heterogeneous legacy sprawl in the data center. Its combination of processing power, I/O bandwidth, extreme reliability, virtualization, and shared modularity with other HP Converged Infrastructure platforms make it a cost effective solution for the next generation data center.

HP-UX Virtualization and Resource Management solutions that are available on the new HP Integrity servers The following HP-UX Virtualization and Resource Management solutions, within the HP Insight Dynamics―VSE, are offered―

On all new HP Integrity servers:

• HP-UX Secure Resource Partitions (SRP) • Process Resource Manager (PRM) • HP Integrity Virtual Machines (Integrity VM or HPVM)

And additionally on the HP Superdome 2 servers: • HP nPartitions (nPars) • HP-UX Virtual Partitions (vPars) • HP Instant Capacity (iCAP)

These solutions provide mechanisms for isolating workloads within servers to offer flexibility of dynamic resizing, while helping to ensure that applications enjoy protection from unrelated events that could otherwise cause disruption, interruption, or performance degradation. When an application is isolated with these solutions, it is able to make use of certain server resources, be managed separately or within a group, and take advantage of unique requirements.

Customers can use these solutions for:

• Consolidation of enterprise-class servers • Isolation of production from test and development • Optimizing individual implementations • Enhancing the availability of applications • Staging roll-outs for new versions of the application or operating system

Since HP offers such a wide range of virtualization solutions, customers can choose the virtualization solutions that best fit the requirements of their environment.

Below is a short description of the HP-UX Virtualization and resource management solutions that are available on the new HP Integrity servers.

HP-UX Secure Resource Partitions (SRP) HP-UX Secure Resource Partitions (SRP) is a shared-OS, container-based, consolidation solution with dynamic, shared resource optimization. It is a lightweight workload deployment environment that enables you to consolidate multiple workloads within a single instance of the HP-UX 11i operating system. SRP provides shared: operating system kernel, system service daemons, administrative domain, and file system namespace. Each SRP has:

• Dedicated or share-based processor and memory resources • An SRP-specific login environment • Isolated process view. (Processes cannot see or communicate to processes in other SRPs.) • A restricted file system view • A dedicated network interface • Per-compartment initialization and shutdown capabilities. • Per-SRP network access and security properties that can be adapted to meet your organization’s

security policies (similar to a single system).

Because SRP enables you to configure and control these features on a per-SRP basis, each SRP forms an isolated execution environment. You can create multiple SRPs within in a single image of an HP-UX operating system, which enables you to consolidate multiple workloads onto a single, shared HP-UX OS image.

HP Process Resource Manager (PRM): HP-UX Secures Resource Partitions (SRP) utilizes HP Process Resource Manager (PRM) to manage processor and memory allocation for your workloads. You may also use PRM directly to allocate portions of processors and memory to specific processes or users, without using the rest of SRP.

HP Integrity Virtual Machines (Integrity VM) HP Integrity Virtual Machines (Integrity VM) is a virtualization or hypervisor technology that enables you to create multiple virtual servers or machines, with shared resourcing, within a single HP Integrity server or nPartition—each with its own “guest” operating system instance, applications, and users.

Integrity VM provides:

• Automatic, dynamic, resource allocation, based on demand and entitlement. • Shared: processor, I/O, and tape and changer access. • Dynamic resourcing through: automatic CPU and memory resource reallocation, and online VM

Migration. • Virtualized: processors, I/O, memory, network, storage, switch, and Virtual LAN (VLAN). • High integration with HP’s Converged Infrastructure solutions: high availability (for workloads and

VMs), instant capacity, blades/rack-mount/logical servers, and manageability tools.

HP nPartitions (nPars) HP nPartitions (nPars) is a high performance and highly scalable hard partition technology that enables you to configure a single server complex as one large server or as multiple smaller servers (for such uses as consolidation). nPartitions offer electrical isolation, enabling: online maintenance of parts of the servers (while others are running), mixed processor architectures and multi-OS support, as well as software and security isolation and compliance.

5

Each nPartition has one or more blades (containing processors and memory) that are assigned to the partition for its exclusive use. Any I/O chassis that is attached to a cell, belonging to a partition, is also assigned to that partition. Each nPartition hosts its own: operating system instance, applications, and users. Service level objectives can be guaranteed through integration with HP Serviceguard solutions.

HP-UX Virtual Partitions (vPars) HP-UX 11i Virtual Partitions (vPars) is a high performance and highly scalable soft partitioning technology, useful for consolidation, which provides finer, core granularity within a single nPartition. Each virtual partition hosts its own instance of the HP-UX 11i Operating Environment (OE), as well as its own: resources, applications, and users. The physical resources of the HP Integrity server are partitioned among the virtual partitions it hosts.

HP-UX Virtual Partitions provides OS, software isolation and compliance. Service level objectives are guaranteed through Integration with HP Serviceguard solutions.

HP Instant Capacity (iCAP) HP Instant Capacity enables you to defer hardware costs for compute resources until you actually need to add them, simplifying capacity planning. Until you need them, you pay only a fraction of the cost. You initially purchase an HP enterprise server with a specified amount of active processing capacity (of processors, cell blades and memory), and a specified amount of inactive processing capacity. Prior to activation of an inactive component, additional usage rights must be obtained. But more importantly, with the tight integration of HP Instant Capacity and HP-UX Virtualization and Resource Management solutions, you can temporarily use spare capacity during peak usage and can move resources between servers, thus accrue higher cost savings.

Real virtualization usage scenarios on the new HP Integrity servers

Data base consolidation with shared resources within one shared O/S instance―via: HP-UX Secure Resource Partitions (an Oracle single instance production example) Usage scenario A customer needs to consolidate a number of Oracle single instance data bases within one server, for a production environment, requiring high: performance, resource utilization, and availability.

Customer objectives • Database consolidation • High: performance, resource utilization, and availability • Granular resource sharing • Increased access control among multiple databases • Application isolation • Lower total cost of ownership

HP solution components • HP-UX Secure Resource Partitions • HP Integrity server

With SRP you are able to create an isolated execution and administration domain for each database, supporting separate installation and management, and access to database software. Each SRP will have its own guaranteed share of system CPU and memory resources.

In this architecture, each Oracle single instance database and associated applications are deployed within a single SRP, creating a 1-to-1 SRP-to-Oracle DB mapping. Database administrators login to the SRP to install the DB instance and perform administrative tasks. For high availability purposes, the entire SRP environment can easily be cloned by using the SRP Export/Import capability to duplicate the SRP on other nodes in the Serviceguard cluster.

You have two choices for CPU assignment with SRP. By assigning CPU shares to an SRP, unused CPU capacity can be used by other SRPs on the system. If you assign dedicated processor cores to the SRP, unused capacity will not be shared, but Oracle will only require you to purchase database licenses for the dedicated processor cores for the SRP, which can yield substantial savings for some deployments.

Data base consolidation with partitioned resources and multiple OS instances―via: HP-UX Virtual Partitions and HP iCAP on Superdome 2 (an Oracle single instance production example) Usage scenario A customer needs to consolidate a number of Oracle single instance data bases within one server, for a production environment. They need a separate OS instance per data base (either for tuning reasons, or different organizations need different OS instances), and high: performance and scalability. Core granularity of the partitions is sufficient. For vPars resource adjustment, customer is enabling/disabling processor cores with HP iCAP within individual vPars (or rebooting upon resource re-configuration).

Customer objectives • Database consolidation • OS isolation • High performance • Large partitions • Optimal resource utilization • Adaptation to changing business demands

HP solution components • HP-UX Virtual Partitions • HP iCAP • HP Integrity Superdome 2 server • HP Serviceguard

With HP-UX Virtual Partitions, you can have one OS instance per data base, for which there are separate resources, and that can be separately tuned. Each vPar has its own set of processor, memory, and I/O resources. With the addition of HP iCAP, processor and memory resources can be turned on or off based on changing demand.

Each Oracle single instance database (and its associated applications) are deployed within a single vPar, creating a 1-to-1 vPar-to-Oracle database mapping. Database administrators login to the vPar to install the database instance, and perform administrative tasks. For high availability purposes, the entire vPar environment is backed up by an HP Serviceguard cluster.

HP solution components • HP-UX Secure Resource Partitions • HP Integrity server

It is common to have a single SAP administrative domain for systems running multiple SAP instances.

(With PRM, you assign certain resource shares and priorities to each SAP application. The resources are shared across the servers, despite the number applications. This increases server utilization, and enables rapid deployment.)

With SRP we are able to create an isolated execution and administration domain for each database:

• Allowing you to create multiple SAP administrative domains, one for each SRP • Reducing database license costs by isolating the databases to individual SRPs with dedicated CPUs • Supporting separate installation and management, and access to database software • Guaranteeing each SRP will have its own share of system CPU and memory resources

In this deployment model, each SAP instance is deployed within a single SRP, creating a 1-to-1 SRP-to-SAP instance mapping. Each database is installed in its own SRP with dedicated processor cores corresponding to the terms of the database license. Database administrators login to the SRP to install the SAP or database instance and perform administrative tasks. For high availability purposes the entire SRP environment can easily be cloned by using the SRP Export/Import capability to duplicate the SRP on other nodes in the Serviceguard cluster.

You have two choices for processor core assignment with SRP. By assigning core shares to the SAP SRPs, unused processor core capacity can be used by other SRPs on the system. By assigning dedicated processor cores to the SRP, unused capacity will not be shared, but database licenses will not be required for the remaining processor core capacity on the system, which will be utilized by the SAP instances.

Benefits • Lower TCO from:

– Reduced number of physical servers – Lowered software license costs – Lowered support costs of hardware and software – Reduced power consumption – Reduced data center floor space

• Improve the service levels to business – Shared management of consolidated databases

• Increase the IT flexibility and agility to respond to business changes – Reduce time for application deployment Reduce data base deployment time significantly

Consolidation of enterprise disaster recovery backup environments: with shared resources and multiple O/S instances―via: HP Integrity Virtual Machines (an example) Usage scenario Customer wants to have their redundant disaster recovery servers be virtual, instead of physical. That way, when not used for disaster recovery, those servers resources can be used for other virtual machines and their workloads. In the case of disaster recovery, degraded performance is OK. What’s most important is that the data is retained, even upon failure or disaster. And in this case, the DR servers are not wasted, hot standby servers. They’re running workloads all the time, for which resources can then be automatically shifted if a disaster failover is required.

Customer objectives • Replace redundant physical systems at remote DR site • Cost-effective disaster recovery • Fewer duplicate physical servers • DR servers ready-to-boot; otherwise used for other purposes

Consolidation of enterprise disaster recovery backup environments: with shared resources within one shared O/S instance―via: HP-UX Secure Resource Partitions (an example) Usage scenario Customer needs high availability for a set of workloads, and wants the ability to more fully utilize the capacity of all the servers within the high availability cluster. The customer may also need to occasionally adjust the workload mix in order to adjust to changes in the workload demand.

Customer objectives • Utilize capacity on all cluster servers―not idle –standby systems • Fast failover (no waiting for server power-up or OS boot). • Redundant physical systems at remote DR site

HP solution components • HP-UX Secure Resource Partitions • HP Serviceguard • HP Integrity server

With SRP you are able to create an isolated execution and administration domain for each database, supporting separate installation and management, and access to database software. Each SRP will have its own guaranteed share of system CPU and memory resources.

In this deployment model, each workload is deployed within a single SRP, creating a 1-to-1 SRP-to-workload mapping. A Serviceguard package is created for each SRP. The full set of SRPs are created on one sever in the cluster, and then the export/import feature is used to create clones (copies) of the SRPs to other cluster servers. The Serviceguard cluster administrator then selects which servers will serve as primary and failover nodes for the SRP packages in the cluster.

Benefits • Lower TCO from:

– Reduced number of physical servers – Lowered software license costs – Lowered support costs of hardware and software – Reduced power consumption – Reduced data center floor space

• Simplified Serviceguard environment with the SRP-as-the-package model

Consolidation of legacy, enterprise servers: with shared resources within one shared OS instance―via: HP 9000 Containers (atop HP-UX Secure Resource Partitions, an example consolidating HP 9000 servers onto an Integrity server) Usage scenario A shoe manufacturing company, an HP customer, has a large in-house developed application on an HP 9000 system on its production floor. This HP 9000 application has been in production use for several years and the customer is quite content in using it in the future. However, the customer’s HP 9000 system is soon going out of support. The customer is highly impressed with the new Integrity Superdome servers and wants it to replace their production systems. The customer wants to have its in-house developed application available on the new Integrity Superdome server. The application is dependent on three Independent Software Vendor (ISV) libraries. Unfortunately, all these three ISVs have gone out of business and the customer has lost all in-house expertise on the application as it has not been modified for quite some time. The customer wants to move the HP 9000 application to the new Integrity system with minimal effort, but in an acceptable fashion.

Customer objectives • Ability to run HP 9000 applications on Integrity systems • Transition HP 9000 applications within minimal effort • Deploy HP 9000 applications rapidly • Consolidate multiple HP 9000 servers on a single Integrity system

Conclusion HP’s new Integrity servers, based on HP’s Converged Infrastructure strategy, attack IT sprawl with a standards-based, modular, bladed architectures as well as common components and a common management environment across all HP servers. The result is a set of servers that are modular, modern, and easier to manage than ever before.

With these new servers, customers can architect solutions with: more efficiency, higher levels of availability, flexibility and service, and do so, with lower total cost of ownership.

These servers, based on the HP Converged Infrastructure, are ideal mission-critical platforms for customers seeking to either migrate off or consolidate, older legacy servers, a proven approach for reducing heterogeneous legacy sprawl in the data center. The servers’ combination of processing power, I/O bandwidth, extreme reliability, virtualization, and shared modularity with other HP Converged Infrastructure platforms make them a cost effective solution for the next generation data center.

Virtualization is a key enabling technology for HP’s Converged Infrastructure.

Virtualization enables customers to:

• Improve utilization of their servers • Optimize application performance • Maximize application availability • Minimize the TCO • Protect operating environments

Together this technology works to enable:

• Server or application consolidation • Maximizing the availability of multi-tier applications such as SAP • Optimizing the use of server resources

As illustrated in this white paper, HP Integrity virtualization technologies on the new HP Integrity i2 Blade (BL8x0c i2) and Superdome 2 servers play a key role in high-end UNIX servers. Customers should determine the virtualization requirements of their workloads, and then determine the best HP virtualization options for meeting such requirements, utilizing common virtualization usage scenarios outlined in this paper.
