  • What environmental conditions are required for the DS-6505B's operation?
    It operates within a temperature range of 0°C to 40°C, with a relative humidity of 10% to 85% non-condensing at 40°C. For non-operating and storage, it withstands 10% to 90% relative humidity at 70°C and can be used at altitudes up to 3,000 meters.

Product Review

The Brocade DS-6505B offers flexible scalability with 12 out-of-the-box 16 Gb/s Fibre Channel ports, expandable to 24 ports, catering to varying network sizes and growth. While its auto-sensing ports and full line-speed switching capabilities ensure optimal performance, the switch's reliance on a Ports On Demand (POD) license for expansion could be seen as a limitation for immediate, cost-effective scalability. Additionally, the inclusion of a single hot-swappable power supply unit as standard, with the option for a redundant unit, strikes a balance between reliability and initial cost, but the necessity for an additional purchase to achieve redundancy could be a drawback for environments requiring high availability.


The Brocade DS-6505B switch is designed for environments requiring high-speed Fibre Channel connectivity. It supports 24x 16Gb SFP+ ports, with 12 active ports as standard. These ports are capable of auto-sensing 4, 8, and 16 Gb/s speeds, ensuring compatibility with various Fibre Channel devices. The switch's capacity can be expanded to 24 ports using the Ports On Demand (POD) license, providing flexibility for growing network environments. Performance-wise, the DS-6505B delivers full line-speed switching capabilities at multiple rates: 2.125 Gbps and 4.25 Gbps line speed, both operating at full duplex. This ensures efficient handling of data traffic without bottlenecks. With an aggregate bandwidth of 384 Gb/s, the switch is capable of supporting demanding data environments with ease. The switch is designed with 8,192 frame buffers per 24-port group, dynamically allocated to ensure smooth data flow and reduce congestion. It also features hot-swappable components, including a single power supply unit that comes with integrated cooling fans. An optional dual redundant hot-swappable power supply is available for enhanced reliability and uptime. Installation is straightforward, as the DS-6505B is designed to fit into any standard 19-inch cabinet that adheres to the EIA 310 specifications. Its slim 1U profile conserves valuable rack space while providing high-density Fibre Channel connectivity. - Maximum Frame Size: Supports a 2,112-byte payload for efficient data transfer. - Data Traffic Types: The switch is optimized for unicast fabric switches, ensuring reliable data delivery. - Management Access: Features various management access points including Ethernet (RJ-45), in-band over Fibre Channel, serial port (RJ-45), and one USB port for flexible administration. The enclosure is designed with back-to-front airflow (port side exhaust) to maintain optimal operating temperatures, ensuring reliable performance under various conditions. The switch measures 437.64 mm in width, 43.18 mm in height, and 443.23 mm in depth, with a system weight of 7.82 kg with one power supply unit and 9.16 kg with two power supply units, excluding transceivers. Operating temperatures range from 0°C to 40°C, with a non-operating temperature range of -25°C to 70°C.
