The Arista Networks DCS-7050SX is a high-performance, leaf-and-spine capable data center switch in Arista’s renowned 7050X Series. With 48 dual-speed 1/10 GbE SFP+ ports and 4 flexible 40 GbE QSFP+ uplinks, the DCS-7050SX-64 delivers uncompromising wire-speed L2/L3 forwarding, ultra-low latency, and robust telemetry—perfect for scale-out data centers, cloud networks, and high-performance compute environments. Powered by Arista’s extensible EOS, the DCS-7050SX-64 brings programmability, automation, and observability into a dense 1U form factor.
Built for demanding data center environments, the Arista Networks DCS-7050SX combines cutting-edge performance with operational simplicity:
High Port Density & Flexible Uplinks — 48 SFP+ support 1/10 GbE, while 4 QSFP+ ports support 40 GbE or break out to 4×10 GbE.
Exceptional Low Latency & Throughput — Up to 2.56 Tbps switching capacity, 1.44 Bpps packet throughput, and cut-through latency from just 550 ns.
Efficient Design — Typical power use is under 2 W per 10 GbE port, with flexible front-to-back or back-to-front airflow models.
Adaptive Buffering & Storage Support — 12 MB (or 16 MB in some configs) of dynamically shared packet buffer, plus optional SSD for logging and local services.
Arista EOS Automation & Telemetry — Leverage Linux-based EOS for advanced automation, programmability, and visibility across your network.
The Arista Networks DCS-7050SX packs 48 auto-sensing 1/10 GbE SFP+ ports with four optional 40 GbE QSFP+ or 4×10 GbE breakout uplinks—ideal for modular expansion and scalable architectures.
This switch can sustain 2.56 Tbps of switching capacity and 1.44 Bpps forwarding rate. Its cut-through architecture delivers nanosecond-level latency for demanding workloads.
Designed with both front and rear airflow options to suit hot-aisle/cold-aisle setups. Each 10 GbE port consumes less than 2 W, ensuring energy-conscious operations.
Equipped with a shared buffer pool—12 MB, or up to 16 MB in some versions—to adapt dynamically to bursty traffic. Supports optional SSD for local analytics or logging.
Arista’s extensible EOS provides scripting, automation, stateful CLI, streaming telemetry, and deep network visibility—empowering infrastructure as code and maximizing operational efficiency.
The Arista Networks DCS-7050SX is ideal for building high-speed leaf switches with ample 10/40 GbE interfaces and programmability at scale.
Low latency and high port density make this switch ideal for clusters that demand high throughput and minimal delay for data-intensive workloads.
High-density 10 GbE and unified QSFP+ uplinks enable multi-tenancy, overlay networks (e.g., VXLAN), and agile infrastructure deployment.
Its sub-microsecond latency aligns perfectly with high-frequency trading and latency-sensitive telecom applications.
Non-blocking architecture ensures full throughput under any load.
Cut-through switching delivers consistent low latency, even under congestion.
Adaptive buffering smooths traffic bursts, while onboard SSD boosts local troubleshooting.
Energy-efficient operation reduces TCO, thanks to low power per port.
Compared to comparable 10/40 GbE switches, the Arista Networks DCS-7050SX offers:
Lower latency and higher density over alternatives.
Programmatic control and telemetry via EOS—unmatched in many legacy platforms.
Highly efficient power usage with balanced cooling design.
Optional SSD for in-switch services — making it a multi-function tool.
Organizations choose the Arista Networks DCS-7050SX for its combination of:
High-density I/O flexibility with breakout-capable QSFP+ ports.
Super-low latency and massive throughput for modern workloads.
Data center-friendly cooling and power efficiency.
Rich EOS for automation, telemetry, and programmability.
Built for future-proof scale in cloud and HPC environments.
In summary, the Arista Networks DCS-7050SX is a powerful, efficient, and highly programmable data center switch designed for the most demanding environments. Its combination of dense port density, ultra-low latency, advanced buffering, power efficiency, and extensible automation stacking make it a top-tier choice for scale-out infrastructure. Backed by Arista EOS and cloud-scale capabilities, the Arista Networks DCS-7050SX ensures your network is ready for the future.
