Wondering what an IBM Power Systems solution can do for you? Ask your IBM sales representative or business partner to help you arrange a no-charge evaluation to assess your savings. Find out more at the IBM Migration Factory (www.ibm.com/systems/ migratetoibm/factory).

POWER7 technology brings not just affordability, but also performance. The design went from a dual-core architecture to up to eight cores per socket. The processor provides Simultaneous Multi-Threading and TurboCore* capabilities that maximize results for both Web applications requ i r i ng h ig h pa r a l lel i sm a nd databases that need streaming. Users can run not only mixed workloads on the same server but multiple operating systems, too. To understand how POW ER7 machines compare with x86 boxes, the logical thing may be to turn to benchmarks. After all, benchmarks offer performance comparisons on a level playing field. Or do they? The Power Systems hypervisor that acts as the backbone of PowerVM runs constantly in the background, so whenever a Power Systems machine processes any workload, whether for a benchmark or not, virtualization is active. In contrast, most x86 benchmarks typically measure just the bare operating system without virtualization. This approach ignores the fact that VMware can impose a system overhead of as much as 40 percent, depending on the workload ( w w w. i b m .c o m / s y s t e m s / p o w e r / software/virtualization/whitepapers/ powervm_x86.html). Once again, what appears to be a side-by-side comparison is not. A VMware environment boasting 60 to 70 percent utilization actually loses significant computing speed to virtualization. Because the PowerVM hypervisor was designed in from the beginning rather than as a software add-on, it’s more efficient and imposes less overhead. “If you compare the Power 750 with a comparable x86 box, Power can provide 65 percent better perfor32

mance and that’s because VMware automatically impacts performance by 20 to 40 percent,” Friske says. “There’s no performance impact with PowerVM.” Ultimately, the mismatch hardly matters. In benchmarks of an SAP workload running on a virtualized four-socket POWER7 server versus a nonv ir tualized four-socket x86 machine, the Power Systems architecture still provided 1.5-times better per for mance ; for t he equivalent eight-socket machines, the Power Systems platform achieved twice the performance of the x86 (www.sap.com/ solutions/benchmark/sd2tier.epx).

Look, Ma, (Almost) No Hands
It’s easy to get caught up in TCA, especially when you’re staring down the end of a quarter. In fact, the cost of operations is the hidden budget buster that your organization will grapple with over and over. It’s not enough to buy a collection of x86 servers. They must be deployed and networked, provisioned and loaded with applications, not to mention maintained. Instead of developing new services to keep the enterprise nimble, your IT staff will scramble just to keep the systems up and running. According to a recent survey of CEOs (www.ibm.com/businesscenter/ cpe/html0/199672.html), roughly 70 percent of the average IT budget goes to system administration. Consolidating to fewer cores cuts not only costs, but also the time IT staff must spend updating applications and managing the system. Meanwhile, PowerVM virtualization lets them provision virtual machines in minutes by leverag ing excess capacity already in the system. Even better, the process can be automated, letting users more rapidly receive resources they need and freeing IT staffers to focus on new services and new challenges rather than plodding through mundane provisioning tasks. Through Power technology, IBM helps your IT department become an enabler of innovation and a catalyst for change, rather than an inhibitor. The reliability of the Power Systems environment isn’t just a consequence of clever engineering but an overall design philosophy. It’s a product of everything from redundant power-

supply cabling to backup memory that ensures that if one component fails, another can capture the data. Similarly, processors run constant background self-diagnostics so that if one goes down, the hypervisor will distribute its workload across the others. All of this contributes to Power Systems running AIX* environments boasting 99.997 percent availability, 2.3 times better than the next best UNIX box and more than 10 times better than the best x86 entry (http://bit.ly/cZ30Ns). “The Power Systems architecture is designed not to fail,” Burke says. “We’ve had customers who’ve run a Power Systems box for 10 years. They haven’t rebooted it, they haven’t even touched it and it’s still going.”

The Best Basket
IBM has refined every part of its stack for security, reliability, availability and performance. “The Power Systems platform is designed from the chip to the virtualization technology, to the operating system—all the way through applications, in many cases—to deliver customers a product that’s extremely secure, with industry-leading, CAPP EAL 4+ security certification,” Burke says. “The only server that’s more secure is the System z* mainframe.” As business processes become more interrelated and complex, IT is being called upon to rapidly solve challenging new problems—and do it in a more streamlined and costeffective manner. Thanks to IBM, they can. The POWER7 family of servers redefines performance, with scalability, reliability, and energy-efficiency that outpace competitors and empower clients to deliver new services faster and with higher quality and superior economics. No matter how critical your workloads, you can consolidate them on a Power Systems machine with confidence. “If you’re putting all your eggs in one basket, you’d better have a good basket,” Friske says. With the Power Systems platform, you get the best.
