Product Review

The Brocade BR-VDX6740-64-R offers high-density 64P SFP+ ports and a significant switching bandwidth of 1.28 Tbps, catering to environments requiring extensive throughput and connectivity. However, the lack of 1/10 GBASE-T ports might limit flexibility for networks not solely reliant on SFP+ connections. Additionally, its 850 ns port-to-port latency, while sufficient for many applications, may not meet the needs of ultra-low latency environments.


The Brocade BR-VDX6740-64-R is a compact, high-performance networking switch, designed to facilitate the rapid deployment of enterprise-class services within data centers. This switch comes equipped with 64 SFP+ ports that support 1/10 GbE, providing a versatile interface for a wide range of network configurations. Additionally, it offers the flexibility of up to 32 out of its 64 10 GbE ports being configurable as Fibre Channel Flex Ports, supporting 2/4/8/16 Gb speeds. This capability allows for seamless integration with existing storage networks, making it an ideal solution for environments that require high bandwidth and low latency connections. This 1U form factor device boasts a switching bandwidth of 1.28 Tbps (data rate, full duplex) and delivers switch performance up to 960 Mpps (million packets per second), ensuring efficient handling of data traffic even in the most demanding scenarios. The port-to-port latency is remarkably low at 850 ns, which significantly enhances the performance of time-sensitive applications. The hardware specifications of the BR-VDX6740-64-R include: - Dimensions measuring 43.99 cm in width, 4.32 cm in height, and 40.99 cm in depth, and a weight of 8.66 kg (19.1 lb), making it suitable for rack installations in data centers with limited space. - Two hot-swappable, load-sharing AC power supplies and N+1 redundant cooling fans integrated into the power supplies, ensuring uninterrupted operations and reliability. - Support for up to four 40 GbE QSFP+ ports (utilizing 10 GbE breakout cables) and the capability to enable additional 10 GbE Ports on Demand (PoD) in increments of 24, 32, 40, 48, 56, or up to 64, providing scalability and flexibility in network design. - 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. It is designed to perform in environments with humidity levels from 10% to 85% non-condensing during operations and 10% to 90% non-condensing for non-operating and storage conditions. - Engineered to function at altitudes up to 3,048 meters (10,000 feet) when operating and up to 12 kilometers (39,370 feet) for non-operating and storage, ensuring reliability across various deployment locations. Key features include: - <>
