IBM finally catches up with Power7
Glad IBM's Power7 announcement brought you excitement. Its clear that you enjoy making statements that have absolutely no substantiations-its what we call FUD.
Sun and Oracle have been shipping its third generation UltraSPARCT2+ servers for over two years now, so comparisons against it is a bit behind the times. So its great news to finally see IBM catching up in the world of multi-core processors! Having been dual-core for almost a decade, IBM has finally been proven wrong and now agrees with what Sun has been telling the world since 2005! Multi-thread, multi-core is the only way to address todays datacenter challenges. But to really address these challenges, its going to need more than a great CPU and that’s where IBM falls flat. AIX still hasn't been proven to scale beyond 128-threads (yesterdays Power 595 or todays Power 750) with no real world commercial workload benchmarks to prove it can scale. Sure, IBM will lead you to believe this with all the 4 x socket CPU only benchmarks you want, but where are the 8 x socket benchmarks besides the IBM typical SPECCPU results? which hide any I/O or OS challenges they surely have.
Where are the 8 x socket Java, SAP, TPC-C or even better, TPC-H benchmarks to prove all this might??
Where are the Oracle based benchmarks? Do realize that Oracle is #1 in OLTP, Data Warehousing, Middleware, Customer Relationship Management , Human Capital Management, Enterprise Performance Management. Without Oracle based benchmarks, IBM is pigeonholing Power7 into a niche market.
Yeah, IBM will iron out the AIX scaling kinks-eventually. Sun had the same challenges with Solaris back in 2005 and has had 5+ years to optimize and tune to this new world of massive multi-threading, now proven to run up to 512 threads in a single OS image today. But by the time AIX catches up, Oracle will be delivering UltraSPARCT3 and the follow-ons that will again leapfrog IBM's Power CPUs, and will also get squeezed from the other end with Oracle/Fujitsu delivering the follow-ons to SPARCVII+, which by the way, are being developed and has been committed to publicly. You can see the roadmaps clearly identified on slides 16 & 17 in following public presentation.
So while Power7 may be a great CPU, and has finally caught up, its going to be dragged through the mud by AIX and scalability challenges. And oh, have you seen the actual pricing for Power7? WOW-It sure won't compete against Sun CMT-especially at 4x the pricing for same # of sockets/cores!
