What's the purpose of a dedicated IPMI network connection? My motherboard has 1x Realtek RTL8201N PHY (dedicated IPMI). So now that I have located my server to the room it will stay in, I've routed three ethernet cables to it, for the 2 NICs and this dedicated IPMI. I don't see any difference compared to not having it connected.
I'd like to upgrade to 10GB SFP+ as soon as I can afford it. I'm also looking at building a security camera system w/ PoE switch, cameras, and a WD purple drive. I've done a little bit of reading here on STH about it.
