  • Oracle Virtualization Technology and the SAP NetWeaver Adaptive Computing Controller

    Introduction

    Implementing SAP landscapes using Oracle virtualization technologies can help IT

    organizations reduce costs, respond to green computing initiatives, and improve service levels.

    For example, the Oracle Solaris™ operating system (OS) includes support for Oracle Solaris

    Containers™. Oracle Solaris Containers enable multiple applications — including SAP product

    components such as SAP R/3 Enterprise applications, application server, and database

    servers — to each run securely on a single virtual system, potentially improving IT efficiencies

    and reducing costs. The SAP NetWeaver Adaptive Computing Controller manages all of the

    SAP instances across containers within a predefined SAP NetWeaver Adaptive Computing

    Controller pool. The combination of the SAP NetWeaver Adaptive Computing Controller and

    Oracle Solaris Containers allows IT administrators to quickly respond to increasing demand by

    moving SAP applications to a more powerful server, and to flexibly utilize excess capacity from

    otherwise idle servers.

    Challenges

    Many IT executives face the challenges of rising energy costs, an overcrowded datacenter, and

    increasingly demanding service levels. The price of energy, like the amount of energy consumed per

    server, storage device, or router, is inexorably rising, while pressure builds on companies to reduce

    their carbon footprint. Many companies are burdened by the cost of basic system administration, with

    10% to 40% server utilization in a sprawling datacenter leaving a burdensome legacy from the days of

    one application per server. Meanwhile, worldwide operations and the pressures of global competition

    ensure that outages of even non-core server applications impact productivity. Most large companies are

    exploring every avenue to cut the cost of IT power, cooling, and administration, while striving to

    increase service availability and provide 24 x 7 business continuity.

    Introduction to Virtualization

    The rapidly maturing computing technology known as server virtualization addresses the need for

    server consolidation, increased business agility, and greater business continuity. The online reference

    Wikipedia (www.wikipedia.org) defines virtualization as “simulating some effect or condition on a

    computer”. It defines a virtual machine as “a software implementation of a machine that executes

    programs like a real machine”. There are many different kinds of virtualization: storage virtualization

    presents mass storage as a resource without exposing the details of individual devices, while network

    virtualization provides security isolation and different service levels using common physical networking

    infrastructure. Server virtualization technology, in its different implementations, provides the means to

    support multiple computing environments on a single computer.

    Benefits of Server Virtualization

    The benefits of server virtualization include consolidation, increased business agility, and greater

    business continuity. IT organizations can improve efficiencies and reduce costs by maximizing asset

    utilization. Server virtualization can result in fewer physical servers — reducing management, power,

    and cooling needs. IT staff can then shift their focus to responding rapidly to changing business needs,

    provisioning services and infrastructure more quickly, and increasing business agility. The improved

    security and increased application isolation provided by virtualization can also improve business

    continuity.

    Purpose and Intended Audience

    This paper is intended for CIOs, IT department heads, and system administrators with responsibility

    for large SAP application deployments. It highlights the reasons to consider running SAP applications

    using Oracle virtualization technologies and the SAP NetWeaver Adaptive Computing Controller. It

    outlines the required baseline environment and the basic steps to install and tune an SAP NetWeaver

    Adaptive Computing Controller landscape in an Oracle Solaris environment, and provides pointers to

    additional information.

    Current SAP NetWeaver Adaptive Computing Controller Environment

    SAP’s multiyear Adaptive Computing initiative is focused on simplifying IT operations while

    containing IT costs. One major technical goal of the initiative is to enable the movement of individual

    SAP instances within the IT landscape, or, in SAP parlance, to be able to “start any service — any time

    — on any server”. The SAP NetWeaver Adaptive Computing Controller, new in SAP NetWeaver PI

    7.1, is the central point of control for managing SAP application services and obtaining status

    information, and allows an administrator to start, stop, and relocate SAP instances.

    Benefits of the SAP NetWeaver Adaptive Computing Controller

    The SAP NetWeaver Adaptive Computing Controller lowers the net cost of hardware and the cost of

    ongoing operations, reducing TCO. It increases productivity while enhancing flexibility and scalability.

    SAP claims that turning off unused equipment with the SAP NetWeaver Adaptive Computing

    Controller can reduce IT energy consumption by up to 30%.1 The SAP NetWeaver Adaptive

    Computing Controller enables IT administrators to manage hardware resources dynamically across

    predefined pools — with identical operating system interfaces — and assign resources to applications

    (Figure 1). This allows IT organizations to respond dynamically to changing business needs without

    huge new investments in IT resources.
