Brand:

Arista

Specifications

Product Overview

The Arista DCS-7280CR2K-30-F from the advanced 7280CR Series is a powerful Layer 2/3 switch engineered for high-throughput, ultra-low latency environments such as hyperscale data centers, cloud infrastructure, and service provider networks. Equipped with 30 QSFP28 ports, it supports multiple Ethernet speeds — including 100G, 50G, 40G, 25G, and 10G — offering both flexibility and investment protection.
Delivering 6 Tbps switching capacity and a forwarding rate of 2.51 billion packets per second (Bpps), this switch is built for demanding workloads. Its front-to-rear (F-R) airflow design with red-handle components ensures thermal efficiency for hot/cold aisle deployments. Backed by Arista’s EOS operating system and AlgoMatch-2, it also supports extensive routing scalability and deep telemetry capabilities.

Key Features

Port Density: 30x QSFP28 ports supporting speeds from 10G to 100G
High Bandwidth: Up to 6 Terabits per second (Tbps) switching fabric
Ultra-High Throughput: Handles up to 2.51 Bpps
Flexible Ethernet Speeds: 100G / 50G / 40G / 25G / 10G compatible
Advanced Routing Scale: Supports up to 1.3M IPv4 LPM routes and 1M IPv6 LPM routes
Packet Buffer: 12GB deep-buffer ideal for congestion handling and lossless networking
Latency: As low as 3.8 microseconds — ideal for real-time applications
