Hi Chris, I have used several different IMPI solutions, the advantage it offers is primarily to give you the ability to control different vendors node management systems with the same command line (ok, different arguments sometimes). But the hardware implementation greatly differs: some IMPI cards share the same ethernet port as the system, and some other have their dedicated port. Personnaly, I prefer the second solution, because I encountered some problems with shared ethernet port implementations, leading to a lack of IPMI connectivity during PXE boot phase, or when the node was booted on FreeBSD OS, this is an issue if your node is stuck in PXE because it needs a missing initrd from the TFTP server.
I think you should have a look at the different models embedding their dedicated LAN, if you don't mind loosing a PCI slot on your node. I don't know why no vendor is providing a solution to control several nodes directly using the PINs on the motherboard, is is safe, inexpensive, reliable and scalable.
