The Arista DCS-7050SX3-48YC8-R 7050X3 Series 48 Port Switch

The Arista DCS-7050SX3-48YC8-R is a next-generation Layer 3 rack-mountable switch designed for modern enterprise networks, cloud-scale data centers, and high-density virtualization environments. As part of the advanced 7050X3 Series, this 48-port 10G SFP+ switch with 8x100G QSFP uplinks delivers exceptional throughput, low latency, and scalable network performance. Built with Arista’s Gen3 architecture, this platform ensures seamless integration into leaf-spine topologies, high-speed aggregation layers, and mission-critical enterprise core infrastructures.

48-Port 10G Connectivity with 8x100G Uplinks

The Arista DCS-7050SX3-48YC8-R features forty-eight high-speed 10 Gigabit Ethernet SFP+ ports, delivering wire-speed performance for server access, storage networking, and high-density aggregation. These ports support a wide range of optical and direct-attach copper transceivers, providing flexible connectivity options for short-range, long-range, and high-bandwidth data center interconnects.

Scalable 100G QSFP Uplinks for Spine Integration

Equipped with eight 100G QSFP ports, this switch is optimized for spine-leaf architectures and high-throughput backbone connectivity. The 100G uplinks can be deployed for high-speed aggregation, core switching, or data center interconnect applications, ensuring seamless data flow between racks, pods, and facilities. These uplinks can also support breakout configurations, allowing flexible migration paths to 40G or 4x25G deployments when required.

Optimized for Leaf-Spine Data Center Architectures

In modern leaf-spine designs, east-west traffic patterns dominate network workloads. The 7050X3-48YC8-R ensures low-latency forwarding and non-blocking architecture, allowing consistent performance even under heavy virtualization and containerized workloads. Its deep buffering and advanced traffic management capabilities make it suitable for latency-sensitive applications such as financial trading platforms, real-time analytics, and high-frequency transaction systems.

High-Performance 7050X3 Architecture

As part of the powerful 7050X3 product line, this Gen3 switch offers exceptional throughput, deep buffering, and wire-speed Layer 2 and Layer 3 features. It is purpose-built to handle east-west traffic patterns commonly found in modern virtualized data centers and hyper-converged environments.

Layer 3 Routing Capabilities

The Layer 3 capabilities of the Arista DCS-7050SX3-48YC8-R provide comprehensive routing support for dynamic and static routing protocols. This switch supports advanced IP routing, enabling scalable network segmentation, traffic optimization, and high-availability configurations across enterprise and service provider environments.

Rack-Mountable Form Factor

The rack-mountable chassis allows seamless integration into standard 19-inch racks. Its compact 1U design maximizes rack space efficiency while delivering high port density and superior airflow management.

Gen3 Architecture and Performance Efficiency

The third-generation hardware architecture in the DCS-7050SX3-48YC8-R delivers significant improvements in performance, efficiency, and scalability. Designed with high-performance switching silicon, this platform ensures ultra-low latency and high throughput across all ports.

Rear-to-Front Airflow for Efficient Cooling

This model features rear-to-front airflow, making it ideal for hot-aisle and cold-aisle containment strategies commonly implemented in enterprise and hyperscale data centers. Proper airflow design ensures consistent thermal performance, reducing operational risks and improving hardware longevity.

Redundant Power Supplies and Reliability

The inclusion of two power cords supports redundant power supply configurations, ensuring uninterrupted operation in case of power failure. High availability is critical for mission-critical networks, and this design enhances resilience while minimizing downtime.

Arista EOS and Advanced Network

The DCS-7050SX3-48YC8-R runs on Arista’s Extensible Operating System (EOS), a Linux-based network operating system known for stability, programmability, and modular architecture. EOS provides a single binary image across all Arista platforms, simplifying upgrades and operational management.

High-Speed Storage Networking

With 10G server access and 100G uplinks, the switch supports storage protocols and high-bandwidth replication workloads. This makes it suitable for SAN, NAS, and distributed storage architectures requiring minimal latency and high throughput.

Comprehensive Management and Deployment Flexibility

Deployment is streamlined with the inclusion of two power cords and a console cable, enabling immediate setup and configuration. The intuitive command-line interface and web-based management tools provide flexibility for administrators of varying experience levels.
