A good answer was provided by Justin and is quoted in the following:

The "partition" _physically_ divides the hardware. You supply power 
individually 
to partitions, so it is possible to suffer a severe hardware issue 
(e.g. power 
fail) in a domain in one partition, and domains in the other partition 
to be 
unaffected.

Creating a domain across a partition doesn't make sense; the only 
reason the 
concept of partitions exists is to allow the user to divorce one domain 
for 
another, e.g. for clustering within the same cabinet.
By segmenting or partitioning your Sun Fire, you place some repeater 
boards, 
system boards, i/o etc into one partition, and the rest in the other. 
The 
address buses are split so that each partition has a individual bus. 
They 
physically cannot talk to each other, so domaining is impossible across 
the
