[Beowulf] recommendation on crash cart for a cluster room: full cluster KVM is not an option I suppose?

I've got a rolling cart, 15" vga and keyboard, not a big deal.
it's technically an AV cart - provides two other shelves, and
enough space for a pad or some tools, even a node sometimes.

thank goodness for lan IPMI (bios, serial console redirection) -
it keeps me out of the machineroom 99% of the time. heck, it keeps
me out of the dozen other machinerooms that our ~30 clusters are in.

not worth it imo - I'd use the crash cart, since the need is so rare.

ipmi ipmi ipmi. try to avoid the obnoxious nonstandard proprietary POS's
that vendors push. you want remote power on/off/reset, then serial
redirect and hopefully bios redirect too. then temperature monitoring,
and SEL access. this should be in every entry-level server IMO.
you know the vendor has jumped the shark if/when they provide xml-based
scripting and offer licensed extended features rather than standard ipmi
