Features
The Cisco Nexus 5020 switch is a 2 RU, top-of-rack switch that provides Ethernet and Fibre Channel
consolidation in a single physical cable. The Fibre Channel over Ethernet (FCoE) protocol is used to
consolidate Ethernet and Fibre Channel traffic onto the same physical connection between the server and
the switch. As a top-of-rack switch, all the servers in the rack connect to the Cisco MDS 9200 Series,
and it connects to the LAN or SAN.
