The Cisco Nexus 5020 is a two-rack-unit (2RU), 10 Gigabit Ethernet, FCoE, and Fibre Channel switch built to provide 1.04 terabits per second (Tbps) throughput with very low latency. It has 40 fixed 10 Gigabit Ethernet and FCoE Small Form-Factor Pluggable Plus (SFP+) ports. The first 16 fixed ports support both 10 Gigabit Ethernet and Gigabit Ethernet in hardware, providing a smooth migration path to 10 Gigabit Ethernet. Two expansion module slots can be configured to support up to 12 additional 10 Gigabit Ethernet and FCoE SFP+ ports, up to 16 Fibre Channel switch ports, or a combination of both.
