Brocade 7840 Technical Specifications
The Brocade 7840 Extension Switch provides Fibre Channel, FICON, and FCIP performance for remote
replication, backup, and migration. Up to 24 2/4/8/16 Gbps ports Fibre Channel ports, 16 1/10 GbE, and
two 40 GbE optical ports support scalable bandwidth, port density, and throughput that extend Storage
Area Network (SAN) fabric connectivity over distance.
