Product Review

The Brocade M6505 offers high-speed 16 Gbps Fibre Channel performance, with auto-sensing port speeds ensuring optimal connectivity for a variety of network demands. Its compact size and low weight make it suitable for environments with limited space, without compromising on the high aggregate bandwidth of 384 Gbps for efficient data transfer. However, the device's operational temperature and humidity ranges could pose limitations in extreme working conditions, potentially affecting its deployment in environments outside the specified operational parameters.


The Brocade M6505 is a Fibre Channel switch designed to support data center SAN environments with its 16 Gbps port speeds, enhancing both performance and scalability. It comes with an initial configuration that includes 12 active ports, with the option for a 12-port upgrade, facilitating flexible network expansion. The switch is equipped with two 16 Gbps SFP+ optics, ensuring high-speed connectivity and data transfer rates. Auto-sensing capabilities enable the switch to detect and operate at 2, 4, 8, and 16 Gbps speeds, optimizing performance based on the connected devices. This feature ensures compatibility with various generations of Fibre Channel devices, allowing for seamless integration into existing networks. The M6505 boasts an aggregate bandwidth of 384 Gbps, end-to-end, in full duplex mode, providing a high-throughput environment for data-intensive applications. Latency is minimized in the network, with locally switched ports experiencing only 700 ns of delay. An additional 400 ns is added between E_Ports due to Forward Error Correction (FEC), ensuring reliable data transmission across the fabric. The switch supports a maximum frame size of 2112-byte payload, accommodating large data packets for efficient network traffic management. Physically, the M6505 is compact, measuring 272.75 mm in width and height, and 307.24 mm in depth, with a system weight of 2.10 kg without media. This makes it suitable for environments where space is at a premium. Its operating temperature ranges from 0°C to 40°C, while in non-operating conditions, it can withstand temperatures from −20°C to 70°C. Humidity tolerance is 10% to 90% non-condensing at 29°C when operating and 5% to 95% non-condensing at 38°C when not in use. Designed to perform in various environmental conditions, the M6505 can operate up to an altitude of 3048 m and withstand operating shock of 20 G for 6 ms and non-operating shock of 50 G with a velocity change of 4216 mm/sec^2. Vibration resistance is also notable, with the device able to handle 0.4 G at 5 Hz to 500 Hz for 60 minutes when operating and 0.5 G at 2 Hz to 200 Hz for 15 minutes in non-operating conditions. The switch is powered through a DC input of 12 V and 3.3 V from the chassis, with a power consumption ranging from 30 W under normal conditions to 40 W at maximum load. Key features include: - Full fabric architecture supporting up to 239 switches, enabling extensive scalability for growing network demands. - Availability of SFP media and Ports on Demand for a 12-port upgrade, offering customization to meet specific network requirements. - Efficient power consumption, ensuring operational efficiency and reducing energy costs. The Brocade M6505 is engineered to meet the demands of high-performance networking, providing a reliable, scalable solution for today’s data centers.
