Arista

Specifications

Product Overview

The Arista DCS-7280QR-C36-M-F is a hybrid-port, high-performance data center switch engineered for demanding enterprise, cloud, and service provider environments. It combines 24x 40G QSFP+ ports and 12x 100G QSFP28 uplinks, offering flexible connectivity in dense network topologies. Built with a front-to-back airflow design and a resilient power and cooling setup, this switch ensures optimal thermal management in high-density rack deployments.
With a switching capacity of 4.32 Tbps, a forwarding rate of 1.44 Bpps, and ultra-low latency of 3.8 microseconds, this switch is ideal for performance-sensitive workloads such as real-time analytics, financial trading, AI/ML workloads, and large-scale virtualization.

Key Features

Port Configuration: 24 x 40GbE QSFP+ ports + 12 x 100GbE QSFP28 uplink ports.
Switching Capacity: Up to 4.32 Tbps of throughput for high-scale environments.
Forwarding Rate: Capable of handling up to 1.44 billion packets per second (Bpps).
Latency: Ultra-low starting at just 3.8 microseconds, ideal for time-sensitive applications.
Cooling: Front-to-back airflow (F-B) ensures effective heat dissipation in rack-optimized deployments.
SSD Included: Onboard SSD storage improves performance for logging, telemetry, and advanced features.
Redundancy: Comes with 2 x hot-swappable 745W AC power supplies and 4 x FAN-7000-F fan modules (N+1 design).
Advanced CPU: Quad-core x86 architecture with 8GB DRAM (upgradeable to 32GB) and 4GB Flash.
