Brocade G720/G620 San Switch

System Architecture

Fibre Channel ports

Switch mode (default): 64 ports (48 64G SFP+ ports, plus 8 2x64G SFP-DD ports), each supporting E_Ports, F_Ports, M_Ports, D_Ports, and EX_Ports.

24-port base configuration; additional ports are enabled with three 8-port SFP+ PODs (Ports on Demand), plus a 16-port SFP-DD POD (8 2x64G SFP-DD transceivers), scaling the switch from 24 ports to 64 ports.
Brocade Access Gateway default port mapping: 56 F_Ports, 8 N_Ports.

Scalability

Full-fabric architecture with a maximum of 239 switches.

Certified maximum

4K active nodes; 56 switches, 19 hops in Brocade Fabric OS fabrics.

Performance

Fibre Channel: 8.5Gb/s line speed, full duplex; 10.53Gb/s line speed, full duplex; 14.025Gb/s line speed, full duplex; 28.05Gb/s line speed, full duplex; 57.8Gb/s line speed, full duplex; auto-sensing of 8, 10, 16, 32, and 64G port speeds. 10G optionally programmable to fixed-port speed.
