The Nexus 3100 series builds on the Nexus 3000 switching platform, which Cisco 
first announced in March of 2011. Gabriel Dixon, marketing manager for Data Center and Virtualization at Cisco, told Enterprise Networking Planet that the new Nexus 3100 series does not replace any top-of-rack switches already in the Cisco portfolio.
“It’s an additional member, thereby giving the customer even more choices,” Dixon said.
Those choices currently include two Cisco Nexus 3100 switch models. The Cisco Nexus 3172PQ scales up to to 1.4 terabits per second of Layer 2 and 3 switching capacity. The Nexus 3172PQ is a top-of-rack switch including 48 SFP+ ports and 6 Quad SFP+ (QSFP+) ports. The SFP+ ports can deliver 10 Gbps/1 Gbps/100 Mbps speeds. The QSFP+ ports can provide 40 Gigabits per second or can be split up in a 4 x 10-Gbps mode.
Going a step up is the new Cisco Nexus 3132Q Switch, which can scale up to 2.5 terabits per second. The Nexus 3132Q provides 32 Enhanced QSFP ports and 4 SFP+ ports.
