Do you mean an F6800 or an E6500?  In any case, they're completely 
different from the E10k, and don't use an (external) SSP.  The E6500 
works pretty much like any other sun workstation/server (just with a 
lot more processor slots).  You can actually run it off a 15A 120V 
circuit, outside of its rack enclosure.  I've done it before. :)  Just 
make sure it's not fully loaded, and you don't have anything else on 
the circuit at the same time...

The F6800 supports some domains (2 or 4 maybe?), but is an awful machine 
to try and keep running (or at least the ones we have at work are), and 
eats up LOTS of juice.  It uses 4 x 208/240V 30A circuits (which are 
actually 2:1 redundant, you only need 2 circuits).  One of the 5 we've 
got seem to always throw a processor board when they are powered off 
and back on... the processor isn't actually bad, it just gets disabled 
by the firmware, which requires a support call (and a magic string 
typed by the Sun support tech) to fix.  Our senior hardware guy managed 
to wrangle it out of Sun because of the number of problems we've had... 
I'm not sure if it varies by machine (based on serial number) or if 
it's the same for everything.... I guess in the case of failures, 
they're about as reliable as E10k's are. :)

You can probably get shipping costs lowered quite a bit if you have them 
ship it to you without the rack... just make sure that they ship you 
the key switch module (in the rack) and cable that connects from the 
system to the keyswitch with the system.  Otherwise, it'll be a bit 
hard to turn it on. :)

I've done that before.  It was my Linux first box with 22-24 processors 
and about the same GB of RAM. :)  I don't remember any specific 
problems with running Linux on it, I think it worked properly
