domains.  and a domain is nothing at all like a Virtual Machine.  on a mainframe
when it's your turn to run, you get the entire machine.  when you split an e10k
up into domains, each "machine" is limited to what you allocate to that domain.

i have yet to see a mainframe with a CPU that can touch anything else on the
market.  i also have yet to see anything else on the market that can touch the
I/O of a mainframe.
