Product Review

The Arista DCS-7280SE-64-R offers high-speed connectivity with 48xSFP+ & 4x40GbE QSFP+ interfaces, catering well to environments demanding 10/40/100GbE configurations. However, its ultra-deep 9GB packet buffer, while advantageous for managing data bursts, may represent an over-specification for operations not encountering extreme traffic conditions. Additionally, the switch incorporates comprehensive features such as VXLAN support and advanced mirroring with DANZ, but its reliance on older OpenFlow 1.0 and 1.3 protocols could limit future-proofing in rapidly evolving network architectures.


The Arista DCS-7280SE-64-R is a high-capacity, fixed-configuration switch designed to meet the demands of the most performance-intensive environments. It offers a combination of 48 SFP+ ports and 4 40GbE QSFP+ ports, supporting a variety of speed configurations including 10, 40, and 100GbE to accommodate a wide range of networking needs. This switch is engineered to deliver wire-speed Layer 2 and Layer 3 performance, ensuring efficient handling of traffic and routing functionalities across a network. One of the standout features of the DCS-7280SE-64-R is its ultra-deep 9GB packet buffer, which significantly reduces packet loss in high-volume environments, making it ideal for data centers with heavy traffic loads. The switch also includes advanced redundancy features, such as 1+1 redundant and hot-swappable power supplies and N+1 redundant, hot-swappable fans, which ensure uninterrupted operation and high availability of network services. Users have the option to configure the system's cooling mechanism for either front-to-rear or rear-to-front airflow, facilitating its deployment in a variety of data center environments. Designed to meet NEBS requirements, the Arista DCS-7280SE-64-R is built with reliability and durability in mind. Its tool-less rails support simple and quick installation, reducing setup time and complexity. Network virtualization is supported through VXLAN, enabling the creation of next-generation data centers. The switch also supports VM Tracer, OpenFlow versions 1.0 and 1.3, and LANZ for microburst detection, providing comprehensive tools for network monitoring and management. Additional features include DANZ Advanced Mirroring & TAP for enhanced network visibility and troubleshooting, support for between 128K and 256K MAC addresses, and similar capacities for IPv4 and IPv6 host routes. This ensures the switch can handle large-scale deployments and complex routing requirements. Moreover, with a 64K IPv4 route capacity, it is well-equipped to manage extensive routing tables. The inclusion of a 120GB solid-state drive offers ample storage for logs and data captures, enhancing the switch's capability for diagnostics and analysis. Furthermore, full access to the Linux shell and tools leverages the power of open-source technologies, allowing for customization and the use of a wide range of software tools without limitations.
  • 48x1/10GbE SFP+ and 4x10/40GbE QSFP+ ports for flexible connectivity options.
  • Ultra-deep 9GB packet buffer for managing high traffic volumes with minimal packet loss.
