Frequently Asked Questions

What are the primary port configurations for the Arista DCS-7280SR2A-48YC6M-F? +

The Arista DCS-7280SR2A-48YC6M-F is a high-density managed switch featuring 48 SFP28 ports capable of supporting 10G or 25G speeds. Additionally, it includes 6 QSFP28 uplink ports, which support 100G connectivity. This configuration makes it an ideal solution for leaf-and-spine architectures requiring high bandwidth and flexible port density for modern data center environments.

What specific cooling airflow configuration does the 'F' suffix denote in this model? +

The 'F' suffix in the product model indicates a front-to-rear (port-to-power) airflow design. This cooling orientation is specifically engineered for data centers using hot-aisle/cold-aisle containment strategies. It ensures that the switch draws cooler air from the front port side and exhausts heat through the rear of the rack, maintaining optimal operating temperatures for enterprise hardware.

Is the DCS-7280SR2A-48YC6M-F suitable for high-performance deep buffer applications? +

Yes, this model is part of the Arista 7280R series, which is specifically designed for deep buffer requirements. Its architecture provides significant packet buffering, making it well-suited for environments with high-burst traffic, such as data storage, content delivery networks, and complex financial trading platforms where preventing packet loss during congestion is mission-critical.

How does this Arista switch handle complex network management and automation? +

This switch runs on the Extensible Operating System (EOS), Arista’s advanced network operating system. EOS provides a robust programmable interface, supporting standard-based APIs and automation tools like Ansible and Puppet. This allows network administrators to manage large-scale deployments efficiently through programmatic provisioning, telemetry, and comprehensive configuration management capabilities.

What kind of deployment scenarios is the 7280SR2A-48YC6M-F designed for? +

This switch is optimized for massive-scale cloud data centers, high-performance computing, and enterprise core deployments. Because it supports advanced features like VXLAN routing and large-scale tables, it serves as a powerful leaf or spine switch. It is specifically built to handle heavy traffic loads while providing the architectural flexibility needed for modern virtualized and containerized environments.

Does this switch support advanced Layer 3 routing features? +

Indeed, this device provides full Layer 3 routing capabilities, including support for BGP, OSPF, and IS-IS protocols. It is designed to handle sophisticated routing tasks at scale, including the ability to manage complex multi-tenant environments. Its hardware-based forwarding ensures that high-speed routing is performed at line rate, preventing performance bottlenecks in intensive network environments.

What is the physical rack space requirement for the DCS-7280SR2A-48YC6M-F? +

This unit is designed as a 1RU (one rack unit) device. Its compact physical footprint allows it to fit standard 19-inch enterprise server racks, facilitating easy integration into existing infrastructure. Despite its small size, it delivers substantial throughput and port density, helping you maximize rack space efficiency while maintaining high performance across your data center architecture.

How does the Arista EOS software licensing work for this managed switch? +

Arista uses a flexible licensing model for EOS, allowing customers to enable specific features through software licenses. These keys unlock advanced functionality such as MACsec, advanced routing, or specific telemetry packages. When purchasing, ensure you select the appropriate feature set that aligns with your specific networking requirements to ensure all necessary capabilities are operational upon deployment.

Can I receive a bulk quote for multiple Arista DCS-7280SR2A-48YC6M-F units? +
