Power—it's an IT obsession. Getting enough processing power at a good price is always a priority. Reducing total cost of ownership is also a concern. Getting power into the hands of the right people at the right time to improve service is a daily challenge. If you're ready to migrate to servers that meet all your business and IT requirements, you need to learn more about POWER6 processor-based technology.
IBM Power™ Systems Linux, i, and UNIX servers are setting new standards for performance, availability and efficiency. The IBM Power 570 and Power 595 use industry-leading POWER6 processor capabilities to provide a superior RISC server consolidation platform The IBM Power 520 Express, IBM Power 550 Express, and IBM Power 560 Express use the same technology to provide outstanding single application and distributed application performance and are also consolidation platforms for smaller enterprises. The IBM BladeCenter® JS12 Express, JS22 Express, JS23 Express, and JS43 Express blade servers leverage those same capabilities in the industry-leading BladeCenter chassis. With jaw-dropping performance – of up to two to three times that of HP servers and Sun servers – and higher energy efficiency than RISC competitors, it's no wonder that the industry is buzzing about Power servers. Built on smart consolidation, virtualization and distributed platform strategies, POWER6 technology makes it easy to allocate the power you need and to get it under control. Running UNIX®, IBM i, operating system and Linux® workloads, Power Systems perform. Want to talk specs and stats?

Go Green and Save
Power efficiency. The POWER6 energy efficiency story is very simple. Start with processors that deliver two to three times the maximum performance per core so that you need less hardware. Consolidate and use PowerVM™ virtualization to get tremendous utilization of those fast processors and the other hardware in POWER6 processor-based servers. Leverage EnergyScale™ technology to control and minimize the energy required to do your job. And manage all the energy management features with Active Energy Management tools. The result is huge energy savings – up to 90% in some cases. Learn more about Power Systems power efficiency compared to competitive UNIX servers.
Manage Growth, Complexity and Risk
Power performance and power availability. Power Systems servers grow with your business. That's the beauty of the modular design of the Power 520 Express, 550 Express, 560 Express, 570 and 595 for scale-up applications and the BladeCenter chassis for scale-out applications. Linear scalability is central to our systems. Using the SPECjbb2005 benchmark as an example the 16-core Power 570 result is 54,249 bops per core, and the 64-core Power 595 has a result of 53,679 bops per core.1 Now that's scalability! And the total performance of the 64-core Power 595 of 3,435,485 bops is 1 2/3 the performance of an HP Integrity Superdome with twice the number of cores (128) and 1.95 times the performance of a Sun SPARC Enterprise M9000 with four times the number of cores (256).2 The performance of the 64-core 595 is even more breathtaking. The 64-core (32 processor chip, 128 threads) Power 595 has 3.6 times the SAP SD 2-tier benchmark users per core of the 256-core (64 processor chips, 512 threads) Sun SPARC Enterprise M9000 and 2.3 times the users per core of the 128-core (64 processor chips, 256 threads) HP Integrity Superdome.3 So, whether your business is small, medium, large or still growing, Power Systems will provide consistently superior scale-up performance. For scale-out performance, use our IBM BladeCenter H with the JS12 Express JS23 or JS43 Express blades. The BladeCenter H supports up to 14 blades in only 15.75 inches (9u) of rack space. If you need more performance, just add another high-performance blade. If you fill up the chassis, add another one – four fit in a standard 42u rack.

When you run this much work on a system, keeping it running all the time becomes critical to the success of your business. POWER6 processors and our servers were designed with this in mind. Mainframe-inspired availability features like Alternate Processor Retry and First Failure Data Capture are examples of features designed to minimize unplanned outages only available on IBM UNIX, IBM i, and Linux systems. Live Partition Mobility and Live Application Mobility are features of PowerVM and AIX® 6 respectively that allow running partitions or workloads to be moved from one server to another without interruption. Upgrade, perform maintenance, increase processor nodes and barrel through planned outages without disrupting service. According to a study by ITG, over a 5-year period, these IBM exclusives can reduce the cost of downtime up to 59 percent.
Realize Innovation
Power your business to new levels of innovation today and new capabilities tomorrow. The energy efficiency of POWER6 processor-based UNIX servers can allow you to implement new applications that might otherwise have to wait until you build your next data center. The performance and virtualization features of Power Systems and BladeCenter servers can enable you to free up the resources needed for new systems uses. And the availability features of the 570 and JS22 Express give you the confidence that the systems will be there for even the most demanding new tasks. Move up to POWER6 processor-based technology and let innovation begin.
FEATURED CASE STUDIES
Case Study: Energen achieves half-million dollar savings by migrating Oracle and SAP software to IBM Power Systems
Companies around the world have saved money by migrating from competitive UNIX servers and consolidating on IBM Power Systems. For instance, Energen, one of the top 20 independent oil and gas exploration and production companies in the United States, was able to save more than $500,000 annually by consolidating 20 Sun servers onto two Power 570 servers. The project accelerated new server deployment from one month to two days.
"The server consolidation project was hugely successful," said Brunson White, vice president and CIO of Energen. "We have never completed a project that has so quickly generated as much return on investment as this one. And we achieved increased system performance as well."
