[Beowulf] impressions of Super Micro IPMI management cards?

We use them all the time as well, and it has to be said, they are  
flaky as hell.

Sometimes commands work, sometimes they don't.  Currently we have  
about 5 IPMI cards we can't communicate with.  Another couple we  
can't get on the web interface with but can issue commands to using  

Their inability to function correctly really becomes apparent when  
you loose your water chiller and your automated process starts  
issuing power-off commands... and then when you get in, you discover  
that some nodes are still up and your machine room is really really hot.

Having said that, we have yet another bios update to apply... perhaps  
they will work correctly after we get it on?
