Serial over LAN
Encyclopedia
Serial Over LAN is a mechanism that enables the input and output of the serial port
of a managed system to be redirected over IP
.
On some managed systems, notably blade server
systems, the serial ports on the managed computers are not normally connected to a traditional serial port socket. To allow users to access applications on these computers via the serial port, the input/output
of the serial port is redirected to the network. For example a user wishing to access a blade server via the serial port can telnet
to a network address and log in. On the blade server the login will be seen as coming through the serial port.

Blade server
A blade server is a stripped down server computer with a modular design optimized to minimize the use of physical space and energy. Whereas a standard rack-mount server can function with a power cord and network cable, blade servers have many components removed to save space, minimize power...
