Really?<div>&nbsp;</div> You sat " an enterprise-class system"---I guess you definition of an enterprise class system is any system not running Windows Server 2008; or WebSphere on Windows Server? <div>&nbsp;</div> If you will note, the Power6 actually did outperform the Intel-based system on a per-core basis (although I plan to test on the new Intel Nehalem chips--are you in?).<div>&nbsp;</div> But, if you say Power 570 is all about "server consolidation blah blah blah"; please do more to justify the Power6 system is three times more expensive than the Hewlett Packard BladeSystem, running the same .WAR file as the WebSphere/AIX/Pwer 570 server, yet offers much lower performance than the HP BladeSyetem running WebSPhere on Windows Server 2008. I guess your definition of enterprise class is anything not running Windows Server? No matter the cost?<div>&nbsp;</div> Do you really think the Power 570 Server is more reliable? I know it draws a lot more energy; I know if it crashes the entire app is down.....(not true for the scale-out cluster of blades that HP has built in fault-tolerance; plus if any Blade goes down, three are still running). With the price differential, it seems the onous is actually on IBM, not MS, to prove the value. And do not point me at a whitepaper. Meet us in an independent lab, to do any amount of testing you desire, on these workloads. Do not just dismiss this benchmark out of hand. And by the way, I am not new to this, I have been benchmarking WebSphere for almost 10 years now; so come prepared, technically.<div>&nbsp;</div> Cheers,<div>&nbsp;</div> Greg LeakeSenior DirectorMicrosoft Corporation
