One of the powerful tools in IPMI is Serial Over LAN (SOL) which provides serial line
access over the management LAN. The baseboard management controller (BMC)
microcontroller embedded on the server motherboard does this by redirecting information
destined for the serial port over to the LAN. With SOL console redirection system
administrators can remotely view the text-based console on their remote servers from
anywhere and perform any task that doesn’t require a GUI
Transporting serial data over IP networks using telnet, serial over IP, SOL and the likes is
the way forward for server serial communications. Just as the KVM functions in embedded
service processors is displacing the need for external KVM appliances, so the SOL
capability of BMCs and console redirection in service processors is reducing the need for
serial console servers for server console management.
