Well because everything after the U10 is fucking expensive (B1000 is
getting acceptable now). And Sun Hardware sucks because it is simply
not upgradeable. So why do you not understand that people want to work
with an U10 ?

And Linux and Windows supports old hardware very well. Pretty simple to
add a new NVidia to a 1998 machine, or a 800 GB IDE harddrive to an
secondary PCI controller.

On Solaris Sparc => forget it. It sucks.

And to be honest you are counting generations wrong. Just because a
Blade 1500 is 10% faster then a Blade 1000 this is not a generation.
This is a new product thats all. Generations in the Sun Universe take a
lot longer. Even now the CPU is speed is fuckint 1,4 Ghz - single core
- ROTFLMAO.

The correct order is

Ultra-45/-25/SB-1500, SB-2000/1000, Ultra-80/-60/-30
UltraSparc-IIIi UltraSparc-III UltraSparc-II

You are correct that UltraSparc-IIIi is the same generation as the
UltraSparc-III, but the difference is like that of the original Celeron
and Pentium. The UltraSparc-IIIi is a crippled version of the
UltraSparc-III.

If you really want (and you don't) IDE drives buy a SiL IDE controller
and drop a pair of 500gb drives. The performace will be atrocious but
you wanted it! Do you really want a low performance PCI graphics card?
A $4.99 Elite-3D (www.EPCUSA.COM) works very well in a UPA based
machines and will outperform just about all PC cards.

I doubt clock speed has anything to do with how well a RISC chip
performs compared to a CISC chip. Using SLU-DRAS and NCAR-MM5 as test
cases the only thing that comes close to performing as well as my
SB-1000 with 2x1Ghz Copper UltraSparc-III (an old machine) is the
latest generation Opterons at more than double the clock speed. The
current generation U-IV and U-IV+ are dual-core and do much better. As
always your mileage may vary depending on your application, but SPEC
ratings are only a VERY rough starting point. Considering that a
Blade-1000 with 2x1Ghz copper U-III's 4Gb ram, DVD and 146GB 15k FC-AL
is under $500, Sparcs are a good investment. The only thing AMD/INTEL
processors are good for is a medium (~100 node) sized cluster.
Development work proceeds much faster on the Sparc and assuming you
paid attention when you were being taught how to program there are only
a few places where the port to the cluster is difficult.
