I've used both remote KVM and SOL, and both work very well. Your board
must have an active BMC for this to work; as John mentioned, it's not a
default feature (though it's becoming more so on ''server-class''
boards.)
The remote KVM is a Java Web Start applet. I've had some issues getting
it to work, especially on an OS X client. A CentOS client is usually
okay but sometimes flaky. Serial-over-LAN is more convenient to access
but less well documented (which says something, since Supermicro's docs
on their IPMI implementation are generally quite poor).
And +2billion on securing the subnets used to access to the IPMI consoles.
