It features a low latency of 700 ns, maximum frame size of 2112 byte payload, and dynamically allocates 8,192 frame buffers. Designed for efficient operation, it includes dual, hot-swappable redundant power supplies, supports back-to-front airflow for cooling, and consumes up to 464 W of power with all ports active.

Key Feature for the BR-6520-48-16G-R

  • What is the maximum data rate supported by the 48-Port Fibre Channel SFP+ Switch?
    Each of the 48x SFP+ transceiver ports on the switch supports a 16 Gbps data rate.
  • How is airflow designed in the switch?
    The switch features back-to-front airflow, meaning air enters from the back and exits from the front, ensuring efficient cooling.
  • Can the switch's Fibre Channel ports be configured in modes other than the default 48-port setup?
    Yes, beyond the default 48-port configuration, the switch can be set up in 72- and 96-port configurations.
  • What is the aggregate bandwidth of the switch when fully populated?
    When all 96 ports are used at the 16 Gbps data rate, the switch achieves an aggregate bandwidth of 1,536 Gbps.
  • What is the latency of the switch?
    The switch has a latency of 700 ns.
  • What is the maximum frame size the switch can handle?
    The switch supports a maximum frame size with a 2112 byte payload.
  • How are frame buffers managed within the switch?
    The switch dynamically allocates up to 8,192 frame buffers for efficient data handling.
  • What are the physical dimensions and weight of the switch?
    The switch measures 429.25 mm in width, 86.74 mm in height, and 609.75 mm in depth. It weighs 16.92 kg with two power supplies but without transceivers.
  • What environmental conditions can the switch operate under?
    The switch operates in temperatures from 0° to 40°C and humidity from 10% to 85% non-condensing. For non-operating conditions, it tolerates temperatures from -25° to 70°C and humidity from 10% to 90% non-condensing.
  • What are the power specifications and consumption of the switch?
    The switch requires an AC input of 85 V to 264 V, with power consumption of 464 W when fully populated with 96 ports at 16 Gbps SWL optics and 183 W for an empty chassis with no optics. It includes dual, hot-swappable redundant power supplies for reliability.

Product Review

The Brocade BR-6520-48-16G-R switch offers high-density Fibre Channel connectivity with 48 to 96 ports supporting 16 Gbps, optimized for high-throughput data environments, with an aggregate bandwidth of 1,536 Gbps. However, its operational latency of 700 ns may not meet the requirements of applications demanding ultra-low latency. The switch is designed with back-to-front airflow and dual, hot-swappable power supplies, ensuring reliable cooling and power redundancy, but its power consumption peaks at 464 W with all ports active, which could be a concern for energy-conscious deployments.
