Serial connection between servers for recovery
I've heard it was possible to connect servers together through the serial port with some special PCI card... This allows you to remotely access the bios configuration screen and do everything just like if you had physical access to the server, so you do not need to rely on "remote hands" service from your provider.
I would like to have suggestions on which product to use. I will have 2 servers in the same datacenter, I'd want each of them to have a serial connection to the other so if one fails, I can access it through the serial connection of the other, even if the operating system on the crashed server is not even booting.
