Brand:

Arista

Specifications

Product Overview

The Arista DCS-7500R2M-36CQ-LC is a secure, high-density 100GbE line card designed for Arista’s 7500R2 Series modular switches. With 36x 100 Gigabit Ethernet QSFP100 ports, it delivers up to 3.6 Tbps of switching capacity, making it an ideal choice for high-performance data centers, cloud infrastructure, and enterprise networks demanding scalability and security.
A key feature of this line card is the integration of MACsec (Media Access Control Security), providing wire-speed data encryption across all ports. This ensures end-to-end data protection without compromising on performance or adding extra processing overhead.
Built to handle large-scale, low-latency traffic, the module combines energy efficiency, real-time telemetry, and advanced switching capabilities. It supports a wide range of QSFP transceivers for flexible deployment across various network layers.

Key Features

36x 100GbE QSFP100 Ports – Delivers ultra-high-density 100G switching per line card.
MACsec Encryption – Built-in Layer 2 security that encrypts traffic at wire speed with no performance penalty.
3.6 Tbps Switching Capacity – Offers full line-rate throughput on all ports simultaneously.
Low-Latency Design – Engineered for mission-critical workloads and latency-sensitive applications.
Telemetry & Monitoring – Real-time network visibility for fast diagnostics and traffic optimization.
Flexible Transceiver Support – Compatible with a range of Arista QSFP100 optics and DACs.
Energy-Efficient Architecture – Designed to reduce data center power and cooling requirements.
Fully Integrated with Arista EOS – Seamless management, automation, and scalability with Arista’s network operating system.
