[Beowulf] non-proprietary IPMI card?

When comparing cluster offerings, seems reasonable, that the 
additional $85-$100 would be factored in to any system/cluster 
purchase, for at least power up/down and reset?  This is astonishing, 
or is there something I'm missing in this thread? The technology 
mentioned isn't really earth shattering.

Additional system monitoring...like...internal temp...fan 
speed.....cpu/mem/disks, down to rotation rates is readily available. 
There is a very nice technology built into HP DLxxx systems that 
provides pre-failure analysis to system managers. Actually, from what 
I've seen and we've discussed, the goal is to extend the number of 
systems managed per system administrator to higher and higher numbers.

So if it's possible to extend the number of systems per system 
administrator, how about extending the number of systems per cabinet, 
and the number of cabinets per system administrator.  I don't mean to 
minimize the job responsibilities of system managers. Quite the 
opposite, which further exacerbates the notion that in addition to 
the $85-$100....you might somehow have the desire to become a custom 
cable specialist?  BLOODY BRILLIANT....
