[Beowulf] dual Opteron recommendations

[Bill Broadley]

Oh, speaking of which the main advantage I've seen in the newisys is
the remote managability.  You can ssh to the management interface, check
temperatures, turn the machine on/off, and other related functionality.

Alas, as far as I can tell the passthru for the management interface
(it has 2 ethernet ports for the management) isn't usable in any sane way.

Unless you want to do something like:
ssh node001
ssh node002
ssh node003
ssh node004
....
turn node off
exit
...
exit
exit

The idea of not requiring a masterswitch+ for power management, a
cyclades or similar for serial management, or a switch for a seperate
management network can be attractive.  Not that other motherboards
don't have management options.
