Product Review

The Brocade BR-VDX6740-64-F offers high-density connectivity with 64 SFP+ ports and a significant switching bandwidth of 1.28 Tbps, catering to environments demanding high throughput. However, the lack of 1/10 GBASE-T ports might limit flexibility for deployments requiring copper connectivity. The switch's design focuses on efficiency with N+1 redundant cooling integrated into hot-swappable power supplies, though its non-port-side exhaust airflow could pose challenges in certain rack configurations.


The Brocade BR-VDX6740-64-F is a high-performance network switch designed to meet the demands of modern data centers. It features 64 SFP+ ports, capable of supporting 1/10 GbE connections, providing the flexibility needed for diverse network environments. This switch is engineered to deliver a high data rate with a switching bandwidth of 1.28 Tbps and a switch performance of 960 Mpps, ensuring efficient data transfer across the network. Key to its design is the inclusion of AC power supplies, which are hot-swappable and load-sharing, enhancing the reliability and uptime of the network infrastructure. The switch operates with a non-port-side exhaust airflow system, ensuring optimal cooling and performance under various conditions. Its form factor is 1U, making it suitable for space-constrained environments without compromising on functionality. The hardware specifications highlight its capability to handle intensive workloads with a port-to-port latency of just 850 ns. This low latency is critical for applications requiring real-time data processing and transmission. The dimensions of the switch are 43.99 cm in width, 4.32 cm in height, and 40.99 cm in depth, with a weight of 8.66 kg, designed for easy integration into existing rack setups. - 64P SFP+ ports support up to 64 1/10 GbE connections. - 2/4/8/16 Gb Fibre Channel Flex Ports allow for up to 32 connections, offering versatility in network design. - 40 GbE QSFP+ ports include 4 ports with 10 GbE breakout cable capabilities. In addition to Ethernet capabilities, the switch supports various port types, including E_Port (for connection to EX_Port only), F_Port, and N_Port (Access Gateway mode), providing a range of connectivity options for different network topologies. Though it does not feature 1/10 GBASE-T ports, it compensates with 40 GbE QSFP+ ports and the flexibility of 10 GbE Ports on Demand, ranging from 24 to 64 ports, allowing network administrators to scale the network based on demand. The switch's cooling system is designed with N+1 redundancy, integrated into the power supplies, ensuring consistent performance even in the event of a component failure. It operates within a temperature range of 0°C to 40°C and can withstand non-operating and storage temperatures from -25°C to 70°C. Humidity levels are maintained between 10% to 85% non-condensing during operation, with non-operating and storage humidity ranging from 10% to 90% non-condensing. The Brocade BR-VDX6740-64-F is built to operate at altitudes up to 3,048 meters, ensuring reliability in various geographic locations. For non-operating and storage, it can withstand altitudes up to 12 kilometers, providing additional flexibility for shipping and storage conditions. This switch is tailored for organizations looking for a high-capacity, low-latency solution that can efficiently handle large volumes of data, providing the necessary infrastructure to support demanding network environments.
