Cisco Nexus N3K-C31108PC-V

The Cisco Nexus 3100-V platform runs the industry-leading Cisco NX-OS Software operating system, which helps ensure continuous availability and sets the standard for mission-critical data center environments. The platform is designed for programmable fabric, which offers flexibility, mobility, and scalability for service providers and Infrastructure-as-a-Service (IaaS) and cloud providers; and for programmable networks, which automate configuration and management for customers who want to take advantage of the DevOps operating model and tool sets. It is well suited for data centers that require cost-effective, power-efficient, line-rate Layer 2 and 3 Top-of-Rack (ToR) switches. These switches also support forward and reverse airflow (port-side exhaust and port-side intake) schemes with AC and DC power input.
