Brocade Communications Systems BR-5120-0004 Fibre Channel Switch

The Brocade BR-5120-0004 Fibre Channel switch is a SilkWorm-era SAN switch designed for mid-size Fibre Channel fabrics. It combines a 40-port chassis with 24 active Fibre Channel ports, using 8 Gbps SWL SFPs to deliver high-speed host-to-storage connectivity. This model sits in Brocade’s 5100/5120 family and supports Full Fabric functionality, enabling scalable zoning and fabric services across interconnected switches. In typical data-center deployments, it serves as the fabric switch that interconnects servers, storage arrays, and other SAN components, delivering dense port density within a compact form factor while remaining aligned with standard Brocade SAN features.
