I might also add that we tried that on a few Supermicro boxes and found the whole mess to be not as reliable as you'd like an OOB management tool to be. The java client is spotty at best, really wants to be run in Windows, and basically falls apart when doing simple console redirection in the client. Never really saw it work well. > Now it seems more and more problems are coming to light with vendor IPMI > implementations (Broadcom's pseudo-iLO causes ARP storms because there > is no dedicated NIC for iLO and the NIC technically has two MAC > addresses, Supermicro's IPMI and the event log problem, yadda yadda.) Yeah, I was a little disappointed in this - when I read about IPMI I thought that it was something of a standard and that I'd be able to pick and choose clients that run natively on FreeBSD or OS-X. That does not seem to be the case at all. > Seems to me the only vendors who got this right were 1) HP/Compaq with > their true iLO/iLO2, and 2) Sun. Which is a shame as the Supermicro cards were sub-$100...
