Oracle and SUN "Several of the concerns about Oracle's acquisition of Sun have revolved around how Unix technologies led by Sun would continue under the new ownership. As it turns out, Solaris users might not have much to worry about, as Oracle executives on Wednesday affirmed their commitment to preserving the efforts. In the case of Solaris, Oracle had already been a big supporter of the rival Linux operating system. Oracle has its own Enterprise Linux offering, based on Red Hat Enterprise Linux. For Oracle CEO Larry Ellison, the idea that Linux and Solaris are mutually exclusive is a false choice."

Please do not confuse "mainframe" with "big iron." And for what it is worth, IBM will happily sell you an integrated facility for linux® (IFL) subsystem for your shiny new Z-series mainframe.

I know Big Iron and mainframes are not the same thing. I am trying to show that Big Iron are more similar to Mainframe, than a super computer. And we see that mainframes and Super computers are very different, hence, big iron are very different than Mainframes.

But IBM Mainframes are dog slow. One IBM Mainframe with 64 CPUs, offer you 28.000 MIPS. That is 437 MIPS/CPU. You can emulate IBM Mainframe in software with "Herkules" and according to wikipedia, one Intel Nehalem-EX give you 400MIPS. But that is under software emulation, which is 5-10x slower than running native code. If you could run Nehalem-EX in native code, you would need 16 intel CPUs to match one 64CPU Mainframe. As the top configured IBM Unix P595 server which had the old TPC-C record, costed $35 million list price, I dont expect a top configured IBM Mainframe costs much less. Compare that Mainframe price to two 8-socket Intel Nehalem boxes. Which computer would you prefer to run Linux on? IBM Mainframe or two Intel boxes? I bet IBM is willing to sell me a new shiny Z-series Mainframe, but frankly, I would save $35 million and buy a 8-socket Intel box for $25.000(?).

The funny thing is, you need four IBM POWER6 at 5GHz, to match two Intel Nehalem 2.93GHz in TPC-C, according to official benchmarks. Not really fast IBM hardware, eh?

Just because Sun didnt sold much hardware, it doesnt mean Sun made bad hardware. MS sells Windows very well, does that mean that Windows is the best OS? No. Popularity != technical superiority
