Product Review

The Brocade BR-VDX6740-48-R switch offers high switching bandwidth and performance, with a data rate of 1.28 Tbps and a performance of 960 Mpps, ensuring efficient data handling and low port-to-port latency of 850 ns. However, it is limited by having only SFP+ ports without included optics and lacks 10GBASE-T ports, which could restrict connectivity options and necessitate additional investments in compatible modules. The hardware design includes dual hot-swappable power supplies and N+1 redundant cooling, optimizing uptime and reliability within a compact 1U form factor, suitable for dense network environments.


The Brocade BR-VDX6740-48-R is a highly capable networking switch designed for data centers that require high-density and high-speed port configurations. This switch includes 48 SFP+ ports capable of 1/10 GbE connections, providing flexibility and scalability in network design. Notably, it does not come with optics, allowing users to customize their setups based on specific network architecture needs. Powering the switch is an AC power supply, with port-side exhaust airflow design to ensure efficient cooling during operation. The switch is engineered within a 1U form factor, making it suitable for compact rack installations without compromising on performance or port density. Key hardware specifications highlight the switch's capability to handle extensive data throughput and network traffic efficiently: - Switching bandwidth is rated at 1.28 Terabits per second (Tbps) in full duplex mode, ensuring high-speed data transfers across the network. - Switch performance peaks at 960 million packets per second (Mpps), demonstrating its ability to manage large volumes of network traffic with minimal latency. - Port-to-port latency is impressively low at 850 nanoseconds, minimizing delay and enhancing the performance of time-sensitive applications. Physical dimensions of the switch are as follows: a width of 43.99 cm (17.32 inches), height of 4.32 cm (1.75 inches), and depth of 40.99 cm (16.14 inches), with a weight of 8.66 kg (19.1 lb), making it a compact yet powerful networking solution.
  • Support for up to 64 1/10 GbE SFP+ ports and up to 32 2/4/8/16 Gb Fibre Channel Flex Ports out of the 64 10 GbE ports, providing versatile connectivity options.
  • Inclusion of 4 40 GbE QSFP+ ports, with the capability for 10 GbE breakout, allows for further expansion and flexibility in network design.
  • Power efficiency is addressed with two hot-swappable, load-sharing power supplies, complemented by N+1 redundant cooling fans integrated into the power supplies, ensuring continuous, reliable operation.
The switch operates efficiently within a temperature range of 0°C to 40°C and can be stored in conditions ranging from -25°C to 70°C. Humidity tolerance in operation ranges from 10% to 85% non-condensing, and for non-operating or storage conditions, it's 10% to 90% non-condensing. It's designed to work at altitudes of up to 3,048 meters (10,000 feet) when operating and up to 12 kilometers (39,370 feet) for storage, ensuring reliability across various environmental conditions. In terms of connectivity, the switch supports multiple port types, including E_Port (connecting to EX_Port only), F_Port, and N_Port (Access Gateway mode), providing flexibility in network architecture and connectivity options. Additionally, the switch offers 10 GbE Ports on Demand (PoD), with increments from 24 up to 64, allowing network administrators to scale their systems based on demand. The Brocade BR-VDX6740-48-R stands out for its high-density port configuration, low latency, and scalable design, making it an ideal solution for data centers looking to optimize their network performance and reliability.
