Cisco Nexus 31108TC-V Ethernet Switch

The Cisco Nexus^® 3100-V switch platform is the latest addition to the industry's widely deployed Cisco Nexus 3100 platform. The Cisco Nexus 3100-V platform consists of high-density, low-power-consumption, and low-latency fixed-configuration data center switches with line-rate Layer 2 and 3 features that support enterprise applications, service provider hosting, High-Performance Computing (HPC), and cloud computing environments. These switches support a wide range of port speeds with flexible combinations of 1/10/40/100-Gbps connectivity with improved port density and scalability in compact 1-Rack-Unit (1RU) form factors.

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 inputs.

Features and Benefits

The Cisco Nexus 3100-V platform provides following benefits:

High performance and scalability

• The Cisco Nexus 3100-V platform provides wire-rate Layer 2 and 3 switching of up to 2.56 Terabits per second (Tbps) and up to 1.4 billion packets per second (bpps) on all ports.
• The Cisco Nexus 3100-V platform delivers ultra-low nominal latency (approximately 650 nanoseconds [ns]), which allows customers to implement high performance infrastructure for High-Frequency-Trading (HFT) workloads.

Line-rate Virtual Extensible LAN (VXLAN) routing

• VXLAN is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility.
• The Cisco Nexus 3100-V platform offers native line-rate VXLAN routing.
• The Border Gateway Protocol (BGP) Ethernet Virtual Private Network (EVPN) control plane provides scalable multitenancy and host mobility (for more information, refer to the document "VXLAN Network with MP-BGP EVPN Control Plane.
