Escon - Enterprise Systems Connection, management system connection. It is the fiber channel of IBM S / 390, which can be transmitted at 17MB / s in a distance of 60 km. ESCON allows peripherals to span large parks and metropolitan fields. ESCON provides a higher speed and serial interface compared to the copper-based parallel bus and feature channel. The ESCON oriented device is a center and peripheral connecting device, providing 8 to 16 ports (mode 1) or 28 to 60 ports (mode 2). Ficon - Fiber Connector, fiber optic connector. It is an IBM large host passage that is introduced together in 1998 and G5 servers. It is based on Fiber Channel Standard, and the transmission rate of ESCON is increased to full duplex 100MB / s. Each FICON channel can support 4000 I / O operations per second, equivalent to 8 ESCON channels.
