  • How does the switch perform in terms of power consumption and heat dissipation?
    Power consumption is 464 W with all 96 ports populated and 183 W for an empty chassis. Heat dissipation is rated at 1,582 BTU/hr for 96 ports.

Product Review

The Brocade BR-6520-48-8G-R offers high aggregate bandwidth at 1,536 Gbps across 96 ports, which supports efficient handling of data-intensive applications. However, the 700 ns latency might not meet the requirements for environments where ultra-low latency is critical. Additionally, the switch's dual hot-swappable power supplies and integrated cooling ensure high availability and reliability, but its power consumption of up to 464 W with all ports active could be a concern for energy-conscious deployments.


The Brocade BR-6520-48-8G-R is a high-performance 48-Port Fibre Channel SFP+ Switch designed to support the demanding environments of enterprise data centers. With its 48x 8 Gbps SWL SFP+ transceivers, this switch provides a solid foundation for reliable, high-speed storage networking. The switch is engineered to deliver superior functionality through its advanced hardware specifications, focusing on speed, scalability, and operational efficiency. At the core of the BR-6520-48-8G-R's performance is its impressive aggregate bandwidth of 1,536 Gbps, achieved when configured with 96 ports operating at a 16 Gbps data rate. This high bandwidth capacity ensures smooth data transmission across networks, reducing bottlenecks and improving overall system responsiveness. The switch boasts a low latency of 700 ns, facilitating rapid data exchange and enhancing application performance. The BR-6520-48-8G-R is designed to accommodate growing network demands, supporting 48-, 72-, and 96-port configurations through switch mode. This scalability allows organizations to expand their network infrastructure as needed, without significant disruptions or the need for complete system overhauls. A key feature of this switch is its efficient use of frame buffers, with 8,192 dynamically allocated buffers. This optimizes data flow and management, ensuring high throughput and reduced transmission delays. The maximum frame size supported by the device is 2112 byte payload, which is suitable for handling large data packets typical in high-performance computing and storage environments. The switch is equipped with one USB port for simplified management and firmware updates, enhancing usability and maintenance. Its back-to-front airflow design, complemented by dual, hot-swappable redundant power supplies with integrated cooling fans, ensures reliable operation and system longevity. This design aids in maintaining optimal temperatures within the switch, even under heavy load conditions. Physical dimensions of the BR-6520-48-8G-R are strategically designed for rack installations, with a width of 429.25 mm (16.90 in.), height of 86.74 mm (3.42 in.), and depth of 609.75 mm (24.01 in.). The system weight is 16.92 kg (37.3 lb) when equipped with two power supply FRUs, excluding transceivers. This compact form factor allows for efficient use of data center space without compromising on performance. Operating in environments with temperatures ranging from 0° to 40°C (32°F to 104°F) and humidity levels between 10% to 85% (non-condensing), the BR-6520-48-8G-R is built to withstand varied data center conditions. Its non-operating environmental tolerance further demonstrates its resilience, capable of enduring temperatures from −25° to 70°C (−13°F to 158°F) and humidity levels of 10% to 90% (non-condensing). Power efficiency is a notable aspect of the switch, with AC power consumption of 464 W when fully populated with 96 ports using 16 Gbps SWL optics, and 183 W for an empty chassis with no optics. This power efficiency, coupled with a heat dissipation rate of 96 ports at 1,582 BTU/hr, underscores the switch's design for sustainable operation.
