Leverage ‘performance plus’ by deploying virtualisation, availability and management software to fully exploit Power Systems servers.

Power is virtualisation without limits

As businesses look for ways to maximise their IT infrastructure investment returns, they turn to PowerVM virtualisation to consolidate multiple workloads onto fewer systems – increasing server utilisation and reducing cost. PowerVM provides a secure and scalable virtualisation environment for AIX, i and Linux applications built upon the advanced resiliency features and leading performance of the Power Systems platform.

PowerVM offers Micro-Partitioning with the ability to run up to 10 partitions per processor core, and dynamically move processor, memory, as well as input/output (I/O) resources between partitions to support changing workload requirements. PowerVM Live Partition Mobility enables active partitions to be moved between servers, virtually eliminating planned downtime. Live partition mobility can also be used to upgrade workloads between POWER6 and POWER7 processor-based servers without an application outage.

VMControl complements PowerVM by providing automated virtualisation management that minimises time to provision virtual machine images and enables management of system pools. With POWER7, PowerVM and VMControl virtualisation software will support up to 1,000 virtual machines on a single system, providing massive consolidation capability for exceptional costs savings.

AIX: the future of UNIX

AIX exploits decades of IBM technology innovation and is designed to provide the highest level of performance and reliability of any UNIX operating system. According to ITIC’s 2009 survey1, AIX scored the highest reliability ratings among 15 different server operating system platforms.

AIX 6.1 is binary compatible with previous versions of AIX, including AIX 5L. This means that applications that ran on earlier versions will continue to run on AIX 6.1 – guaranteed.2 AIX 6.1 is an open standards-based UNIX OS designed to comply with the Open Group’s Single UNIX Specification Version 3.
