Arista DCS-7050T-64-F 48x 10GB Copper 4x Switch Overview

The Arista DCS-7050T-64-F 48x 10GB Copper 4x 40GB QSFP+ Front-to-Back Airflow Switch is purpose-built for modern data center architectures that demand predictable performance, ultra-low latency, and seamless scalability. As part of the advanced 7050T Series from Arista Networks, this high-density 10GbE top-of-rack (ToR) switch is engineered to support enterprise data centers, cloud environments, virtualization clusters, and high-performance computing infrastructures. With 48 10GBASE-T copper ports and 4 40GbE QSFP+ uplink interfaces, it delivers a powerful combination of connectivity, throughput, and operational efficiency.

High-Density 10GBASE-T Connectivity for Modern Workloads

The 48 fixed 10GBASE-T copper ports are designed to support high-speed connections to servers, storage arrays, hyper-converged infrastructure nodes, and network appliances. Copper-based 10GbE technology offers flexibility and cost efficiency, allowing organizations to leverage existing Cat6a or Cat7 cabling while achieving consistent 10 Gigabit Ethernet performance. This capability is particularly valuable in enterprise and mid-sized data centers where copper infrastructure is already widely deployed.

Seamless Integration with Virtualized Environments

The Arista DCS-7050T-64-F switch is optimized for heavily virtualized server environments running VMware, Hyper-V, KVM, or container-based platforms. Its non-blocking architecture ensures east-west traffic flows efficiently between virtual machines and containers, reducing bottlenecks and improving application responsiveness. High buffer capacity and advanced congestion management features enable stable performance even during peak workloads.

Low-Latency Switching Architecture

Designed for environments where microseconds matter, this Arista 10GbE switch provides ultra-low latency switching that supports latency-sensitive applications such as financial trading platforms, real-time analytics, and distributed databases. The cut-through switching mechanism ensures minimal delay between packet ingress and egress, maintaining high throughput and performance consistency across all ports.

40GbE QSFP+ Uplinks for Scalable Aggregation

Equipped with 4 40GbE QSFP+ uplink ports, the Arista DCS-7050T-64-F enables high-speed aggregation to spine switches or core network layers. These uplinks can be deployed as native 40GbE connections or broken out into 4x10GbE connections per QSFP+ port, offering flexible design options for spine-leaf architectures.

Optimized for Spine-Leaf Network Topologies

In leaf-spine topologies, predictable latency and scalable bandwidth are essential. This Arista leaf switch integrates seamlessly into leaf-spine deployments, ensuring equal-cost multipath routing and consistent performance across all traffic paths. By leveraging its 40GbE uplinks, organizations can scale horizontally without sacrificing throughput or stability.

Future-Ready Network Expansion

The presence of QSFP+ uplink interfaces ensures that the network can evolve alongside business demands. As workloads grow and traffic increases, the high-bandwidth uplinks prevent oversubscription and maintain consistent service levels across critical applications. This makes the Arista DCS-7050T-64-F ideal for expanding enterprise campuses and cloud-scale environments.

Front-to-Back Airflow Design for Data Center Efficiency

The front-to-back airflow configuration of the Arista DCS-7050T-64-F is engineered for compatibility with hot aisle/cold aisle data center layouts. Air enters from the port side and exits through the power supply side, optimizing cooling efficiency and aligning with structured rack designs.

Thermal Management and Energy Efficiency

Efficient airflow design minimizes hotspots and ensures stable operation even under continuous heavy loads. Intelligent fan control adjusts cooling dynamically based on internal temperature sensors, reducing unnecessary power consumption and operational costs. This design supports high-density rack deployments without compromising reliability.

Redundant Power Supplies for High Availability

The switch supports dual hot-swappable power supplies, enhancing uptime and ensuring continuous network operation. In mission-critical data centers, power redundancy is essential to avoid downtime caused by component failures. The hot-swappable design enables maintenance without service interruption.

Advanced Features Powered by Arista EOS

The Arista DCS-7050T-64-F runs on the highly programmable and resilient Arista EOS (Extensible Operating System). Built on a modular Linux-based architecture, EOS provides advanced automation, network visibility, and programmability for modern DevOps-driven IT environments.

Programmability and Automation

Arista EOS supports open APIs, including eAPI and RESTful interfaces, allowing seamless integration with orchestration platforms such as Ansible, Puppet, and Chef. Automation capabilities simplify configuration management, reduce human error, and accelerate network provisioning in large-scale environments.

Zero-Touch Provisioning

Zero-touch provisioning enables automated deployment of switches in large data centers. When installed, the switch can automatically download configuration files and operating system images from a central server, significantly reducing manual setup time and ensuring consistent network configurations.

High Availability and Fault Isolation

The modular design of Arista EOS ensures that faults are isolated to individual processes without affecting the entire system. This process separation increases network stability and minimizes downtime. In addition, stateful fault containment mechanisms maintain control plane integrity even during unexpected events.

Key Specifications and Hardware Architecture

The Arista DCS-7050T-64-F delivers a high switching capacity and wire-speed Layer 2 and Layer 3 performance across all ports. With a non-blocking architecture, it supports full line-rate forwarding for both IPv4 and IPv6 traffic.

Comprehensive Layer 2 and Layer 3 Capabilities

This data center switch includes advanced Layer 2 features such as VLAN tagging, link aggregation, and spanning tree protocols. It also supports robust Layer 3 routing protocols including OSPF, BGP, and IS-IS, enabling scalable and resilient network designs.

Enhanced Security Controls

Security features include access control lists, port security, DHCP snooping, and dynamic ARP inspection. These capabilities protect the network from unauthorized access, spoofing attacks, and traffic manipulation. Integrated role-based access control ensures administrative actions are tightly managed.

Ideal Use Cases for Enterprise and Cloud Data Centers

The Arista DCS-7050T-64-F 48x 10GB Copper switch is suitable for a wide range of deployment scenarios. Its high-density copper ports make it particularly effective in enterprise data centers where servers predominantly use RJ-45 interfaces.

Top-of-Rack Deployment

As a top-of-rack switch, it provides direct connectivity to rack-mounted servers while using high-speed uplinks to connect to aggregation or spine layers. This architecture reduces cabling complexity, improves manageability, and supports scalable horizontal expansion.

Private Cloud Infrastructure

Organizations building private cloud environments benefit from the switch’s automation capabilities, programmability, and consistent performance. It enables rapid provisioning of compute and storage resources while maintaining strict performance and security requirements.

High-Performance Computing Clusters

For HPC clusters requiring consistent low-latency communication between nodes, the Arista DCS-7050T-64-F provides stable and predictable throughput. Its architecture supports heavy east-west traffic patterns commonly found in distributed computing frameworks.
