Actually, only up to 6 CPUs - the system has 4 systemboard slots, but
you need to have at least one I/O board in the system.
Ah, yes... that sounds familiar now. We only had 2 CPU boards, so it
wasn't an issue for our machine.
The E3500 fixed that particular dumbness by having 5
slots, so you
can have 8 CPUs (4 CPU/mem boards) + 1 I/O board...
Handy...
but introduced FC-AL internal drives, which are a pain
in the butt
(and make the internal disk bays basically useless for Linux).
Good to know, but if I'm going to run Sun hardware, it'll be running Solaris.
Ethan, I've got some spare E4000s, which can be
"desk mounted", and have
more cpu/i/o board slots than the E3000, and internal optical/tape
drive slots (but no internal disk bays, unless you use a "disk board").
8U tall, perhaps? I've even got a set of desk-top side covers for
it -- but of course, I don't have the top or bottom covers. The E4000s
I've got came as rack-mounted systems.
Interesting. I don't know much about E4000s.
The only real annoying thing about E4000 systems vs
E3000 systems is
that they only support the 83MHz bus speed, not the 100MHz bus speed;
and the "clock board" they come with only supports a 4:1 CPU clock
multiplier - so you can only do 336MHz CPUs instead of 400MHz, unless
you replace the clock board with one that does a 5:1 multiplier.
I'm not such a CPU speed slut that that is likely to matter to me. I
still fiddle with Sun hardware because they make nice servers and have
more robust hardware than commodity Intel stuff. If I wanted speed,
I'd go out and get the latest X GHz box and throw Linux on it and wait
for it to break. ;-)
As for taking on more Sun hardware myself, at the moment, I have a
Netra (off-topic) that I still need to press into full service. I
picked up some more RAM for it and need to get Solaris loaded, but
that will lead to questions to the "Suns at Home" list, not this one
(the kit is too new).
