Serial over LAN in. On the blade server the login will be seen as coming through the serial port. SOL is implemented as a payload type under the RMCP+ protocol in IPMI. Serial over LAN Serial Over LAN (SOL) 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
Parallel communication entire byte at once (256-QAM). Parallel communication In data transmission, parallel communication is a method of conveying multiple binary digits (bits) simultaneously. It contrasts with serial communication, which conveys only a single bit at a time; this distinction is one way of characterizing a communications link. The basic difference between a parallel and a serial communication channel is the number of electrical conductors used at the physical layer to convey bits. Parallel communication implies more than one such conductor. For example, an 8-bit parallel channel will convey eight bits (or a byte) simultaneously, whereas a serial channel would convey those
