We Try-And-Returned a T5120 server to see how it fared for Sun Rays. It is
sluggish compared to a one year old Opteron (2x2core Opteron 2218, 8GB RAM)
that we have. We didn't do any scientific benchmarks on it, but it takes about
1.5-2.0x longer to log in on the T5120 than it does on the Opteron. We also
decided to go with a model with quad core x86 servers (X4150 from Sun) since
single thread processes feel faster. We found it was more cost effective also
to buy a few more of the Intel servers than it was to go with fewer T5120s with
the knowledge that the Ts scale better without slowing down.

We looked at the T1000/T2000 initially. We eliminated the T1000
because of the lack of redundant power supplies.
We evaluated the T2000 with a 1x8core chip and 8 gig of memory.
The general feeling from users was, "It seemed slower".
They where currently running on V240's with 2 proc and 8 gig of memory.
It does appear that CDE/GNOME uses some floating point, so only
having one FPU per socket was probably the reason.
We wanted to run our performance tests on the Niagra2 chip, but never
got around to it.
I think if you go to the T2000, you will find that it will run slower
but everyone will feel the same slowness and will not suffer from
massive performance spikes when people are hammering the server as we
do in the V240 model.
One thing that also changes was moving from Sol9 to Sol10 as the
Niagra only supports 10.
I think our new model will be to run on top of quad-core x86 systems
running sol10x86 ;-)
This is what I run at home and love it. Just waiting for the SunRay
210 version t (for touch screen) "hint hint... starting the rumor
mill" :-D
Thanks,
