IBM Systems Magazine, Power Systems Edition - January 2011 - 30

The IT landscape is evolving rapidly. Across industries, the traditional concepts of performance are being reassessed and replaced. Simple speeds and feeds no longer suffice. The emerging measures of IT performance focus on agility and the capability to creatively respond to change and capitalize on new opportunities by delivering new services faster. At the same time, IT must provide a reliable infrastructure that can handle rapid growth and manage business risk while meeting elevated service levels. Of course, in these days of “do more with less,” organizations also expect service levels to be met with fewer resources and tighter budgets, which requires IT to also deliver superior economics.

A Front-Line Defense
Gaining superior economics is especially difficult now, when most CIOs face server sprawl spiraling out of control even as individual boxes sit underutilized. Energy demands keep climbing, taxing the power and cooling infrastructure—not to mention the bottom line. Everyone assumes a networked system, but data silos are all too often the reality. Meanwhile, IT departments devote increasingly more of their budgets and time to managing and maintaining their systems rather than deploying new services to increase profitability

or reduce costs. There’s no debate that your company must fight through these challenges. The question is how. Consolidation and virtualization constitute the front-line defenses in the battle. “Customers are starting to realize the advantages of virtualization and consolidation,” says Robert Friske, Power Systems marketing manager. “The issue is that if you’re an x86 customer, you tend to think that’s the best platform for consolidation. Sure, with x86, you might be able to go from 100 servers down to 50, but is that really the result you’re looking for?” Some of the most dangerous sentences began with the words, “One thing I know is that ...” As in, “One thing I know is that going with an x86 platform will cost less than a Power Systems platform.” Not exactly. From the standpoint of total cost of acquisition (TCA), one x86 server might cost less than a Power Systems box, but that doesn’t tell the true story. The reality is that one POWER7* technologybased server can consolidate the mixed workloads of dozens or even hundreds of x86 machines, while providing performance far beyond anything they can offer. “The reason customers get confused is that they do a one-to-one comparison of an x86 and a Power

Systems server, but that’s not what you do with consolidation,” Friske says. “What you really do with consolidation is a many-to-one.” One IBM Power* 730 two-socket system, for example, can consolidate t he work loads of 47 HP ProL iant DL380 G5 machines. Such a migration provides bigger benefits than just a reduction in capital outlay. It can save 98 percent in energy costs alone and 97 percent in f loor space (www. sp e c.or g ) . Fewer ser ver s mea n s fewer machines to deploy, network, provision and load with applications, which means less time and money spent on system administration. More important, the move cuts the number of cores by 83 percent, which shrinks software-licensing fees substantially. Beyond that, there’s the performance boost. If all of the operations take place on the same machine, rather than the database residing on one ser ver and Web appl icat ions on another, the data never goes out onto the network and transactions can run faster and more securely.

Performance Redefined
A key strength of the Power Systems e nv i r o n m e nt i s t h e P o w e r V M * virtualization layer that allows a server to be partitioned into as many as 1,000 virtual machines (see “Virtually Perfect”

The Bottom Line
It’s not a question of whether you can consolidate but whether you can consolidate enough to maximize your savings and justify the exercise. Consider a Web infrastructure running on legacy x86 servers. One option would be to consolidate the workloads onto nine 12-core x86 machines running VMware on Linux*. A better option would be to consolidate the same workloads onto just five IBM Power* 730 Express systems with PowerVM* virtualization. The net benefits compared with the x86 solution?

What about a Domino* mail system based on 41 HP ProLiant DL380 G5 servers? All 164 cores in the system can be consolidated onto a single Power 750 Express 12-core system. The net benefits?
