Cisco Nexus Products in This Design Guide
All Cisco Nexus products run Cisco NX-OS Software, a modular operating system that provides a higher level of
availability as a result of several enhancements such as process restartability and memory protection. Chapter 2 in
this guide explains the characteristics NX-OS and how it compares with Cisco Catalyst IOS

Cisco Nexus 7000 Series Overview
The Cisco Nexus 7000 Series Switch is a modular switch available in a 10-slot or 18-slot configuration.
The Cisco Nexus 7010 Switch features front-to-back cooling compatible with data center hot-aisle and cold-aisle
designs.
designs.
Cisco Nexus 7000 Series Switches provide high-density 10 Gigabit Ethernet port aggregation. With the 10-slot
chassis, the system is capable of an aggregate density of 256 10 Gigabit Ethernet ports, including up to 64 ports of
wire-rate 10 Gigabit Ethernet.

wire-rate 10 Gigabit Ethernet.
The current 32-port 10 Gigabit Ethernet modules support 80 gigabits of bandwidth per slot in the system backplane,
and offer the choice to operate them in “dedicated” or “shared” mode for eight non-blocking 10 Gigabit Ethernet ports
on a single I/O module. Gigabit Ethernet as well as 10 Gigabit Ethernet modules support IEEE 802.1AE MAC security
with hardware-based 128-bit Advanced Encryption Standard (AES) encryption.

The Cisco Nexus 7000 Series offers control plane virtualization with virtual device contexts (VDCs).
The Cisco Nexus 7000 Series supports the ability to forward on all uplinks in typical V-shape or square topologies by
using Virtual PortChannel technology.
