Very Computer

We ordered a RS6000 B80 with dual-CPU configuration. What we want is
one CPU board with 2 CPUs on it, but the agent delivered two CPU
boards with one CPU on each board.

Does this configuration match our specification? What the different
between them? Will the AIX installed multi-CPU kernel on this machine?

TIA,

Yes it matches your config (i.e. you have 2x CPU's), I'm not aware of any
problems doing that. From past experience, upgrading shouldn't be a
problem either, because IBM keep careful track of every piece of
equipment in your server (Assuming it was configured correctly by plant,
and not by some dodgy backroom after market deal).

What I'd wonder is whether the machine architecture would give you a
speed advantage for memory intensive operations this way because the
CPU's wouldn't compete on the same bus for memory accesses (IIRC IBM
usually design in such a way that CPU's on the sme card share bandwidth
to memory, but CPU's on separate cards go through a switch. Not usually a
problem though as the bandwidth available to a single card is usually
plenty).
