IBM AIX and Virtualization

Virtualization is an integral part of an IBM Power Systems Server. The underlying technology is PowerVM and AIX is taking advantage of the provided functionality. Since most of this technology is transparent to the application, SAP products usually run in those environments seamlessly and no specific actions are required. The specific SAP support is documented in SAP notes and should be consulted in advance.

In some cases specific enhancements are available in SAP components to exploit this functionality and in other situations the underlying technology improves the operation of an SAP infrastructure on IBM Power Systems Servers. The published articles in this section will present certain aspects of virtualization related to SAP products running on IBM Power Systems Servers using the AIX Operating System.

Implementing and Using SAP NetWeaver Landscape Virtualization Management on IBM Power Systems and IBM PureFlex Power-nodes

SAP NetWeaver Landscape Virtualization Management software (SAP LVM) is the successor and extension of the SAP Adaptive Computing Controller. This paper focuses on the new features and uses-cases provided by SAP LVM in conjunction with IBM Systems Director managed Power Systems. It describes the IBM infrastructure specifics required to implement and operate an on-premise Cloud Solution for SAP landscapes. The cookbook covers a solution stack tested during a Proof-of-Concept at the IBM SAP International Competence Center (ISICC). This includes SAP Business Suite 7 with IBM DB2 UDB LUW 9.7 database on IBM Power Systems using AIX 6 and AIX 7, IBM Systems Director, IBM TivoliStorage Flashcopy Manager and IBM XIV Storage System. At the time of writing, SAP LVM V1.0 SP3 is generally available.

SAP Applications on IBM PowerVM

A new version of the IBM Redbook "SAP Applications on IBM PowerVM" is now available. Besides updates on topics that have been covered already in the first version of this book, new topics like Active Memory Expansion (AME) and POWER7 are discussed . Another chapter provides a deep insight in CPU utilization metrics on Power Systems. Additional sections cover specifics of the IBM i platform.

SAP Enterprise Data Warehouse for Point of Sales Data Optimized for IBM DB2 for Linux, UNIX, and Windows on IBM Power Systems

This article describes optimizations for SAP Retail and SAP NetWeaver BW regarding efficient data management and processing of large Point of Sales (POS) data volumes on the parallel database IBM DB2 for Linux, UNIX, and Windows (in the following referred to as DB2 for LUW) and a Proof of Concept on IBM POWER7 servers been executed at SAP. One important part of the Proof of Concept was the use of Active Memory Expansion (AME) to show the capabilities and advantages of this feature in the context of SAP workload.

Live Partition Migration of SAP Systems Under Load

This paper documents the findings of a performance test using the PowerVM Live Partition Mobility feature to migrate an active SAP system at different work-load levels. The test sequence shows the impact of various workload levels on the duration of the partition migration.

Using SAP Applications with AME (Active Memory Expansion)

Active Memory Expansion is a new technology for expanding a system's effective memory capacity in IBM's POWER7 systems by integrating memory compression technology to transparently compress in-memory data. This allows more data to be placed into memory and thus expanding the memory capacity of POWER7 systems. The following paper describes a detailed use case based on SAP ERP 6.0 ( Enterprise Resource Planning ), with the focus on achievable capacity gain and related performance considerations.

SAP Applications on IBM PowerVM

IBM provides mainframe-like virtualization technologies in order to achieve better asset utilization, reduced operating costs, and faster responsiveness to changing business demands. SAP customers running an AIX, IBM i, or Linux operating system can leverage the PowerVM technology of the IBM Power Systems® platform. In this IBM Redbook, we describe the technologies and functions, what they mean, best practices and how they apply to the SAP system landscape based on an AIX environment. Many of the described functions are applicable to the other OS platforms as well. Please, use IBM platform specific literature for a detailed listing of supported PowerVM functions.
