The BMC is a CPU running some firmware. It's a low power one though, as it doesn't usually have to do too many things and it should not consume significant power while the main system is off. Some BMCs even run a ssh or http daemon to allow an easier interaction. > It's funny that in spite of this the > IPMI gets hung sometimes (like Gerry says in his reply).

I've been told that some BMCs can't cope with a high network load, especially with broadcast packets. I have always considered the BMC as a blackbox or appliance, good for only one thing, so maybe someone with a better understanding of its inner architecture can provide some more details... -- Bogdan _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
