IBM Takes Command of the UNIX Data Center — POWER7 Enables Growth and Lower Costs (Clipper)
0 likes347 views
IBM is enhancing its leadership in the UNIX data center market with the introduction of the Power7 architecture, designed to provide greater performance, reduced total cost of ownership (TCO), and advanced virtualization capabilities. As enterprise data centers face challenges like increasing data demands and the need for efficient resource management, the Power7 is set to address these by enabling higher levels of consolidation and energy efficiency. This positions IBM favorably as competitors like HP and Sun face delays and uncertain futures, cementing its role as a key player in advancing enterprise IT infrastructure.

IBM Takes Command of the UNIX Data Center - POWER7 Enables Growth, Lower Cost THE CLIPPER GROUP Navigator TM SM SM Navigating Information Technology Horizons Published Since 1993 Report #TCG2009040LI September 21, 2009 IBM Takes Command of the UNIX Data Center — POWER7 Enables Growth, Lower Costs Analyst: David Reine Management Summary Striving for excellence is a human trait shared by many, as we all try to be the best that we can in at least one area under our control. Achieving excellence is a little harder to accomplish; it requires an amount of hard work and dedication that only a select few are willing to deliver. Improving on excellence, on the other hand, requires that rare individual who sets his sights on being the best in the world at whatever he attempts and continues to work harder than everyone else, even after he has arrived at the pinnacle of his quest. Individuals like Olympic athletes Michael Phelps and Usain Bolt each set world records (in swimming and track), yet each continues to train even harder to break their own records and reap the rewards of these continuing efforts. This same quality of continuing to improve on success is an essential requirement for every enterprise data center looking to improve upon the performance of its IT infrastructure, ensure the security and reliability of its environment, and continue to lower the total cost of ownership (TCO) of that infrastructure in the face of increasing demands. The deployment of new applications on new servers and the continuing explosion of data, which tends to be doubling every 12-to-18 months, are putting a strain on the budgets of every enterprise data center around the globe. Programs are being implemented to consolidate and virtualize both servers and storage to reduce the TCO and preserve valuable resources, both human and natural. By reducing the number of physical servers populating the data center, the CIO can reduce the number of systems administrators required to drive the IT infrastructure, as well as reducing the amount of energy necessary to power the data center, and the amount of floor space required to house it. These last two points are especially critical as enterprise data centers approach maximum capacity in both of these categories. In fact, if either is exceeded, the enterprise may be forced to build out a brand new data center at a cost of millions of dollars. For decades, UNIX systems vendors have been providing continual and timely upgrades, enabling cus- tomers to run more applications, respond faster, and/or process more data without having to worry about architecture compatibility. Either the UNIX vendor delivered higher performance, expanded memory, and improved RAS, etc., or the customer would eventually migrate to a better platform. For decades, UNIX server vendors have provided the data center with continual, and timely, upgrade paths. This enables them to replace existing legacy environments with fully compatible servers that run the same operating environments on the same IT architectures with higher performance, expanded memory capacity, and improved RAS (reliability, availability, and serviceability) characteristics. In recent years, this cut-throat battle left three UNIX vendors focused on scale-up, UNIX applications dominating the landscape: IBM, with AIX running on POWER systems, HP with HP-UX on Integrity, and Sun, with Solaris running on SPARC systems. For some, expected upgrade plans have hit a major hurdle; however, with customers now assessing Oracle’s acquisition of Sun, putting the future of SPARC under the microscope, and continued delays in the next generation of Intel’s Itanium archi- IN THIS ISSUE tecture (Tukwila), putting the future of Integrity in question, as well.
