Product Review

The Brocade BR-6520-96-16G switch offers high-density Fibre Channel connectivity with 96 ports capable of 16 Gbps, supporting efficient storage networking with an aggregate bandwidth of 1,536 Gbps, which benefits high-performance computing environments. However, its notable latency of 700 ns might not meet the requirements of applications demanding ultra-low latency. Additionally, the dual, hot-swappable power supplies enhance the system's reliability and uptime, but the power consumption of up to 464 W with all ports active could be a concern for energy-conscious deployments.


The Brocade BR-6520-96-16G is a high-capacity, Fibre Channel switch designed to support demanding data center environments. It offers 96 ports equipped with 16 Gbps SWL SFP+ transceivers, providing a significant throughput for high-speed storage networking. This switch can be configured in 48-, 72-, and 96-port setups, allowing flexibility in deployment based on the specific needs of the network infrastructure. Key hardware specifications of the BR-6520-96-16G include an aggregate bandwidth of 1,536 Gbps, which is achieved by multiplying the 96 available ports by the 16 Gbps data rate per port. This impressive bandwidth capability ensures that data flows efficiently through the network, minimizing bottlenecks and improving overall system performance. The switch's latency is rated at 700 ns, which contributes to its ability to handle high-volume, time-sensitive data with minimal delay. The maximum frame size supported by the device is 2112 bytes, and it has 8,192 dynamically allocated frame buffers. These specifications ensure that the switch can efficiently manage large amounts of data, making it suitable for environments with extensive storage and retrieval requirements. Additionally, the switch features one USB port for management and configuration purposes. Physically, the BR-6520-96-16G measures 429.25 mm in width, 86.74 mm in height, and 609.75 mm in depth. It weighs 16.92 kg when equipped with two power supply FRUs, excluding transceivers. The switch's design is optimized for easy installation and maintenance in a rack-mounted setup. - Operating temperatures range from 0° to 40°C, with humidity levels from 10% to 85% non-condensing. - Non-operating temperature tolerance extends from −25° to 70°C, with humidity from 10% to 90% non-condensing. - The device can operate at altitudes up to 3000 m, with storage capabilities up to 12 km. Heat dissipation is a critical aspect of this switch, with a rating of 96 ports at 1,582 BTU/hr. This indicates the device's efficiency in managing thermal output, ensuring sustained performance under full load. Power requirements are also efficiently managed, with AC input ranging from 85 V to 264 V and power consumption of 464 W with all 96 ports active. An empty chassis consumes 183 W, demonstrating the device's energy efficiency in various operational states. The BR-6520-96-16G is equipped with dual, hot-swappable redundant power supplies that include integrated system cooling fans.
