The Nexus 7700

The Nexus 7700 line, unveiled last June, now gains a six-slot member: the Nexus 7706. The 9RU 7706 is targeted at small core, aggregation and data center interconnect applications, with a switching capacity of 21Tbps, 192 ports of 1/10G, 48 ports of 40G and nine ports of 100G Ethernet.

The 7706 can house a new 10G “F3” module from Cisco for the entire Nexus 7700 line. The module is designed for core, spine, leaf, data center interconnect and SAN connectivity. It features programmability via OpenFlow, Cisco’s onePK, Python and XML APIs, and consumes 35% less power than previous generation “F2” modules for the Nexus 7000 line.

Cisco also unveiled an enhanced 24 port 40G Ethernet F3 module for the 7700 line.

Nexus 5672UP

Among the successors to the Nexus 5500 switches is the Nexus 5672UP. This switch features 72 Unified Ports – ports that support Ethernet, Fibre Channel, or Fibre-Channel-over-Ethernet – and six 40G uplinks for access/leaf applications in the data center.

Nexus 56128

Another 5600 series switch is the Nexus 56128. The 56128 sports 128 10G ports and 12 40G ports, and both the 56128 and 5672 feature 1 microsecond latency, VXLAN bridging and routing, OpenFlow, onePK, Python and XML programmability, and scalability to 1,152 ports through fabric extenders.

Nexus 3172TQ

The Nexus 3172TQ is a 72-port 10GBaseT version of the merchant silicon-based Nexus 3100 line of access/leaf switches. The 3172TQ can function as a VXLAN top-of-rack switch, and also supports OpenStack orchestration and provisioning.
