The Cisco Small Form-Factor Pluggable (SFP) devices for use on the Cisco MDS 9000 Family are industry-standard, hot-swappable input/output devices that plug into a port on any of the Cisco MDS 9000 multilayer directors and fabric switches. The SFPs allow enterprise companies and service providers to make multilayer storage-area networks (SANs) a reality by providing scalable and easy-to-deploy Fiber Channel and Gigabit Ethernet connectivity within a data center and over long distances between multiple data center deployments.
