Features and benefits

Simplified operations

Cisco Embedded Event Manager, Python scripts, touchless boot and configuration, Cisco Data Center Network Manager, XML management tools, and advanced reboot features are included. Use Cisco Nexus Data Broker for visibility and monitoring.

Open programmability

DevOps automation tools (Puppet, Chef, Ansible, etc.) are built in. NX-API offers a common programming approach across switches. Python scripts, Bash shell, and Linux containers support customer applications. OpenStack and OpenFlow support SDN.

Scalability and high performance

Get multitenant scalability with VXLAN support. Cisco bidirectional support simplifies migration to 40 Gigabit Ethernet. AlgoBoost and Warp mode on Cisco Nexus 3500 Series Switches provide one of the lowest latency rates in the industry.

High availability and efficiency

Modular Cisco NX-OS Software supports fault isolation. Switches use redundant, hot-swappable power supplies and fan modules. Shared buffer space handles microbursts, regular data traffic flow, and jitter for increased network efficiency.
