Im a little lost.. why not using ILO/ILOM/DRAC etc.. its all the same thing. Just give each ILO IP a DNS address and ssh to it, log in and there you have all the tools you need, a way to access the system console, power on/off remotely, check hardware events, hell it can even send SNMP traps to a NMS so you get alerts even if the OS dies! Using serial is so old hat, and clunky. Why on earth would anyone be using it at all these days? Serial! LMAO *scoffs*
