The Arista DCS-7050SX2-72Q-F 48-Port SFP+ Switch

The Arista DCS-7050SX2-72Q-F 48-Port 10G SFP+ 6-port 40G Back-to-front Airflow Rack 4GB Flash USB Type A Networking Switch is engineered for high-performance data center environments requiring low latency, high density, and scalable Layer 2 and Layer 3 capabilities. Built on Arista’s advanced switching architecture, this platform is optimized for modern cloud networking, virtualization, storage convergence, and high-frequency east-west traffic patterns. The 7050SX2 series is widely recognized for delivering deterministic performance, robust feature sets, and operational consistency across enterprise and hyperscale infrastructures.

Advanced Switching Performance and Throughput

1.44 Tbps Switching Capacity

With an impressive switching capacity of 1.44 terabits per second, the ARISTA DCS-7050SX2-72Q-F delivers non-blocking architecture capable of handling high-volume east-west traffic in dense virtualized environments.

High-Density 10G Access with Scalable 40G Uplinks

48-Port 10G SFP+ Architecture for Aggregation and Access Layers

The 48 dedicated 10G SFP+ interfaces offer wire-speed performance across all ports simultaneously, making this switch ideal for dense server connectivity. Each port supports a range of transceivers and direct attach copper cables, allowing integration with fiber and copper infrastructures. In modern virtualization clusters where hypervisors generate substantial east-west traffic, this density ensures minimal oversubscription and consistent throughput.

Quad-Core x86 CPU

Powered by a quad-core x86 processor, this data center switch ensures strong control-plane performance and advanced programmability. The powerful CPU supports complex routing tables, automation scripts, and real-time telemetry without compromising performance.

6-Port 40G QSFP+ for High-Speed Spine or Core Connectivity

The six 40G QSFP+ uplink ports enable seamless connectivity to aggregation, spine, or core switches. These uplinks can operate as native 40G interfaces or be broken out into 4x10G connections using breakout cables, enhancing deployment flexibility. This capability supports scalable leaf-spine architectures where predictable latency and non-blocking bandwidth are critical.In spine-leaf designs, the 7050SX2-72Q-F functions efficiently as a leaf switch, providing high-speed uplinks to spine layers while maintaining low-latency server connectivity. This ensures optimal performance for east-west traffic typical in cloud-native and microservices-based applications.

Back-to-Front Airflow 

Optimized Cooling 

The back-to-front airflow configuration is tailored for installations where cool air is drawn from the rear of the rack and exhausted at the front. This orientation supports hot aisle containment strategies that maximize cooling efficiency and reduce operational expenses. By aligning with structured airflow patterns, the switch contributes to improved thermal management and reduced strain on HVAC systems.Efficient cooling is essential in high-density racks where multiple 10G and 40G ports operate simultaneously. The airflow design of the DCS-7050SX2-72Q-F helps maintain consistent performance under heavy workloads while extending hardware longevity.

Redundant Power and Cooling Components

The platform supports redundant power supply units and hot-swappable fan modules, ensuring high availability in mission-critical environments. Data centers requiring continuous uptime benefit from these redundant design elements, which minimize service interruptions during maintenance or component replacement.

Advanced EOS Operating System Capabilities

Arista EOS for Cloud-Grade Networking

The Arista DCS-7050SX2-72Q-F runs on Arista’s Extensible Operating System (EOS), a Linux-based, fully programmable network operating system designed for high availability and operational consistency. EOS provides a modular architecture where individual processes run independently, enhancing fault isolation and system resilience.Network administrators gain access to a single binary image across multiple Arista platforms, simplifying upgrades and reducing complexity. EOS supports advanced routing protocols such as BGP, OSPF, IS-IS, and RIP, along with Layer 2 features including MLAG, VLAN trunking, and spanning tree variants.

Non-Blocking Switching Fabric

With a robust switching fabric capable of handling full line-rate traffic across all 10G and 40G interfaces, the platform prevents bottlenecks even during peak usage. This ensures consistent performance across virtual machines, storage arrays, and application servers.

Comprehensive Layer 2 and Layer 3 Features

Layer 2 Switching Capabilities

The switch supports advanced Layer 2 features including VLAN segmentation, Link Aggregation Control Protocol, Multiple Spanning Tree Protocol, and MLAG for active-active redundancy. These capabilities allow enterprises to build resilient access and aggregation layers while maintaining high bandwidth utilization.

4GB Flash Storage and USB Type-A Interface

Equipped with 4GB of flash memory, the switch can store multiple EOS images and configuration backups locally. This simplifies rollback procedures and ensures rapid recovery during maintenance operations.

USB Port for Easy System Management

The integrated USB Type-A port enables administrators to load firmware updates, save configurations, or perform diagnostics without requiring network connectivity. This feature enhances operational flexibility, particularly in isolated or secure environments.

Leaf Switch in Spine-Leaf Architecture

Within spine-leaf architectures, the switch functions as a leaf node delivering predictable performance and scalable bandwidth. Its 40G uplinks ensure sufficient capacity to handle aggregated server traffic.

High-Performance Computing and Financial Networks

Low latency and consistent throughput make the platform suitable for HPC environments and financial trading networks where performance consistency is paramount.
