Function of SAN Fiber Optic Switch

In the computer storage field, a Fibre Channel switch is a network switch compatible with the Fibre Channel (FC) protocol. It is a fiber-optic based protocol. This document explains how to design highly available Fibre Channel networks. Such a design requires switches with an appropriate hardware design architecture, a solid software implementation, a careful selection of fabric topology, and adherence to implementation best practices. So what are its main functions? 1. [pdf]
