AIX is an open standards-based UNIX operating system designed to comply with the Open Group’s Single UNIX Specification Version 3. 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 2010 survey, AIX scored the highest reliability ratings among 15 different server operating system platforms.1
According to IDC, Power Systems with AIX leads in worldwide UNIX server revenue share.2 In addition, with the introduction of POWER7, there has been an acceleration in client migrations to Power Systems through the IBM Migration Factory in order to take advantage of the exceptional performance, scalability, virtualization and resilience of POWER processor-based systems and Power Systems Software.
The latest AIX 7.1 release features new cluster-aware integration with PowerHA, as well the ability to run AIX 5.2 Workload Partitions to facilitate application migration and reuse. The AIX operating system is available in three Editions for a range of capability and flexibility for both mid-sized and large enterprises.
AIX 7 and the previous release, AIX 6, are 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 7 or 6—guaranteed.3
IBM i is an integrated operating environment with a more than 20-year reputation for exceptional cost effectiveness, security and business resilience. IBM i integrates a trusted combination of relational DB2® database, security, web services, networking and storage management capabilities. ITG reports that costs to use Power Systems and IBM i 6.1 average 41 percent less than x86 servers and Microsoft® Windows®.4
The latest IBM i 7.1 release includes enhanced DB2 support for XML and column-level encryption, automatic movement of hot data to solid-state drives, enhancements to RPG to extend applications to mobile devices and web services, plus enhanced virtualization and resiliency options.
IBM i 6.1 included expanded options for virtualization, upgraded storage and availability management, breakthrough Java™ performance, support for POWER7 and POWER6 and BladeCenter®, and a broad range of middleware and tools to help drive application transformation.
Both Red Hat and Novell SUSE Linux run natively on Power Systems, offering a scalable alternative for open source applications. Reducing x86 server sprawl through consolidation and virtualization is a key priority for many companies today. Linux on Power Systems with PowerVM provides a scalable, virtualized alternative to running Linux on x86 servers.
PowerVM Lx86 cross-platform virtualization technology also enables x86 Linux workloads to run without recompilation and take advantage of the scalability of Power Systems. This means Power Systems clients can immediately benefit from the latest Linux applications.
Power Systems solutions benefit from decades of IBM experience in designing and deploying high availability hardware and software. PowerHA SystemMirror disk clustering solutions are available to help keep your systems—and your business—running 24x7x365.
PowerHA SystemMirror for AIX and IBM i Editions are data center and multisite resiliency solutions designed to help protect critical business applications from outages: planned or unplanned. PowerHA is integrated with cluster aware capabilities in both the AIX and IBM i operating environments. PowerHA pureScale™ technology delivers levels of database scalability and availability unmatched on UNIX or x86 systems, and is offered as a component of DB2 pureScale.
IBM offers tools to protect data from threats and unauthorized access on Power servers running AIX, i and Linux workloads. Data encryption capabilities to protect file systems, data and backup are an integral part of the AIX and IBM i operating systems, both of which also support role-based access control. Whether you want to manage the security of your Power servers, or include other elements in your infrastructure—IBM solutions provide intuitive administration that helps you to define, enforce and audit your business security policy.
Many companies are running into floor space and energy challenges in their data center due to the explosion in data and growth in IT applications. Analysts have projected that up to 70% of large enterprise clients will face the need for major changes to their data centers in the next few years. It is becoming critical for these clients to begin to create a more sustainable and cost efficient IT infrastructure. In addition, being socially responsible yields real business benefits. The POWER7 based systems deliver extraordinary new capability to expand an enterprise’s IT capability without expanding their floor space or even energy consumption. As an example the Power 795 delivers over four times the compute capacity of the Power 595 in the same space and energy envelope. POWER7 technology can potentially quadruple the capabilities of a data center without having to change the size, configuration or power and cooling infrastructure. Efficiencies in space, power, costs, and labor as well as the potential for new market opportunities await the company that focuses on building a more sustainable business and IT infrastructure. Enable the sustainability of your business by improving the efficiency of operations, assets and people, while reducing costs, improving your public image, and opening the door to new opportunities.
Power Systems energy management solutions monitor and control energy usage to help you manage energy efficiency in your data center. Each Power server has EnergyScale™ technology built into the POWER7 processor. Through consolidation and virtualization with PowerVM, businesses have realized dramatic energy savings. And with IBM Systems Director Active Energy Manager™, you can identify trends in your energy usage and thermal profile, turn off processor cores or limit the energy draw across one or a group of Power servers, and track environmental data from applications used to monitor air conditioning units, Uninterruptible Power Supplies and Intelligent Power Distribution Units.
With platform management technologies on Power Systems, businesses not only get a complete picture of their systems and how well they are operating, but also the tools to deploy, optimize and maintain these systems at maximum effectiveness and efficiency.
