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 Nexus 5020 switch,
and it connects to the LAN or SAN.
The Cisco Nexus 5020 switch is a part of a family of switches that provide 10-Gigabit Ethernet and FCoE
ports and both 10-Gigabit Ethernet and native 4-, 2-, or 1-Gbps Fibre Channel ports. The switches
provide consolidated I/O connectivity to both production Ethernet LANs and Fibre Channel SANs in a
cost-effective, high-performance, low-latency Ethernet switch.
