You can get full serial port access (or VGA access if you need it), power control and even get into the bios and watch the bios boot pages The only thing which is inconvenient is the remote media mounting, so I instead bought some micro USB sticks and these live inside the machine. I set my grub boot to boot from the USB (and I can change the bios to boot from the USB if necessary) and it's my failover image in case of boot issues. I used sysrescuecd for my usb boot, but anything should work really (just get the architecture the same as your main image) To be sure it all worked well I never put a keyboard or screen on the machines and the initial install was all done with the machines completely remote. Can't say enough good things about such a setup for Colo, or even just for server rooms where it's a walk to get to the screen and keyboard? Good luck Ed W P.S. I went supermicro, but I gather Dell, Intel and HP all offer IPMI enabled machines and I think it's even trickling down to a few consumer boards now
