Fujitsu doesn't build Sun clones! That really is insulting for them ;-)
They do offer Sparc-hardware, but that's a bit higher up the

But again, they also offer (the same?) Broadcom networking on board.
Just like Dell and HP. And it is a LSI Logic sas-controller on board,
so
if FBSD has trouble with either of those, its hard to find anything
suitable at all in

Not necessarily bad to go with Dell. There are *some* of their
controllers that are wicked fast in some configurations. However,
finding which ones are fast is very
FUD!!!
They don't randomly change the controllers under the same name. If you
order a PERC4e/Si controller you will get the same controller every
time.
Actually Vivek this isn't true. Yes the hardware will likely be the
same, but the firmware rev will likely be different and I have seen

Generally more disks at slower speed - 2 10K disks in raid 0 is faster
than 1 15K disk. More disks also allow more options.
Not at writing they're not (unless you're using RAID0... ugh).

Ben,
My option in disks is either 5 x 15K rpm disks or 8 x 10K rpm disks
(all SAS), or if I pick a different server I can have 6 x 15K rpm or 8

I agree there's better platforms out there than Dell, but the above is

Cheers Shane,
Sounds like you have a very good idea of what to expect. Are these
solid stats or certain estimates? Estimates can vary when it comes
time to start.
The figures all come from how my application interacts with the
database when an event happens, so the scaling of operations
You mentioned a Perc controller, so I'll assume this is a Dell.
My advice is to find another supplier. check the archives for Dell.
Basically you have no idea what the Perc controller is since it is
whatever Dell decides to ship that day.
In general though you are going down the right path

Yes I am looking at either the 2950 or the 6850. I think the only
think that the 6850 really offers me over the 2950 is more
expandability in the spare processor, and additional memory
