Lenovo B6505 12 x 16Gb Fibre Channel SFP+ Managed Switch

The Lenovo 3873AR4 is a Fibre Channel switch that delivers 16 Gb SFP+ connectivity across twelve ports for storage area networks that cannot tolerate slowdowns. Designed for straightforward rack installation, it arrives with twelve short wave 8 Gb SFP+ transceivers already in place, and it can grow to twenty-four ports through the Ports on Demand option. That flexibility lets administrators start small and expand capacity without taking the fabric offline.

Performance is tuned for mission-critical traffic. The switching architecture provides an aggregate bandwidth of 384 Gbps and keeps latency around 0.7 ms, so data from flash arrays, database servers, and virtualization clusters moves consistently and predictably. When backup windows are tight or multiple hypervisors contend for the same storage, the switch keeps throughput steady.

Day-to-day management feels familiar to teams accustomed to Brocade technology. Advanced zoning, dynamic path selection, role-based access control, and detailed event monitoring are built in. Administrators can connect over a dedicated RJ-45 management port, use the local USB interface, or work remotely through SNMP, SSH, or HTTPS.

Hardware reliability matches the software feature set. A hot-plug internal power supply supports optional redundancy, and the 1U chassis ships with a mounting kit for quick placement in dense racks. Combined with adaptive networking features, the platform helps maintain high availability across the entire storage fabric.

Whether the environment hosts a private cloud, a data warehouse, or a set of high-speed backup targets, the Lenovo B6505 gives storage teams the throughput and control they need without unnecessary complexity.
