Arista DCS-7050SX2-128-R - 96x 10Gb SFP+ & 8x 40Gb QSFP+ Back-to-Front Switch

Brand:

Arista

Specifications

Overview:

The Arista DCS-7050SX2-128-R is a next-generation, high-density Layer 2/3 data center switch built to meet the demands of scalable cloud infrastructure, enterprise core deployments, and high-throughput environments. Equipped with 96 × 10 Gigabit SFP+ ports and 8 × 40 Gigabit QSFP+ uplinks, this switch delivers unmatched flexibility for dense server aggregation and high-speed uplink connectivity.
With a powerful 2.56 Terabit per second switching capacity and a forwarding rate of 1440 million packets per second (Mpps), the DCS-7050SX2-128-R is capable of handling intense east-west traffic patterns without performance drops. The ultra-low 550 nanoseconds latency makes it ideal for real-time, latency-sensitive applications like financial services, AI/ML, and big data analytics.
Designed with back-to-front airflow, it supports optimized thermal design for cold aisle data center layouts. It also includes redundant hot-swappable power supplies and modular fan units, providing high availability and operational flexibility.

Key Features:

96 × 10GbE SFP+ Ports for high-density server and access layer connectivity
8 × 40GbE QSFP+ Uplink Ports for high-speed aggregation or spine connections
2.56 Tbps Switching Capacity to support massive throughput
1440 Mpps Forwarding Rate ensures reliable, high-speed packet processing
MAC Address Table Size: 288,000 Entries – Ideal for large enterprise or cloud-scale networks
Ultra-Low Latency (~550ns) – Perfect for time-sensitive applications
Back-to-Front Airflow (Cold-Aisle Ready) – Ensures efficient thermal management
Dual Redundant Hot-Swappable Power Supplies (750W AC Included)
4 × Hot-Swappable FAN-7002-R Modules for reliable airflow and cooling
Arista EOS (Extensible Operating System) – Advanced features for automation, programmability, and monitoring
