BR-G720-56-32G-F Specification
| BR-G720-56-32G-F Specification | |
| 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. |
| ISL trunking | Frame-based trunking with up to eight 64G SFP+ ports per ISL trunk; up to 512Gb/s per ISL trunk; up to two (4 x 32G) QSFP ports per ISL trunk. Exchange-based load balancing across ISLs with DPS included in Brocade Fabric OS. |
| Aggregate bandwidth | 4.096Tb/s |
| Maximum fabric latency | Latency for locally switched ports is <780 ns (including FEC); compression is 1 μs per node. |
| Maximum frame size | 2,112-byte payload |
| Frame buffers | 24K per switching ASIC |
| Classes of service | Class 2, Class 3, Class F (inter-switch frames) |
| Port types | F_Port, E_Port, M_Port, D_Port (ClearLink Diagnostic Port) on 24 SFP+ ports Brocade Access Gateway mode: F_Port and NPIV-enabled N_Port |
| Data traffic types | Fabric switches supporting unicast |
| Size | Width: 440.00 mm (17.32 in.) Height: 43.90 mm (1.73 in.) Depth: 355.60 mm (14.00 in.) |
| System weight | 7.34 kg (16.18 lb) with two power supplies, fans, without transceivers 8.78 kg (19.36 lb) with two power supplies, fans, fully populated with transceivers |
| Operating environment | Temperature: 0°C to 40°C/32°F to 104°F Humidity: 10% to 85% (non-condensing) |
| Non-operating environment | Temperature: –25°C to 70°C/–13°F to 158°F Humidity: 10% to 90% (non-condensing) |
| Operating altitude | Up to 3,000 m (9,843 ft) |
| Storage altitude | Up to 12 km (39,370 ft) |

| AC input | 90V to 264V, maximum input current 4.5A |
| Input line frequency | 50 Hz to 60 Hz nominal, 47 Hz to 63 Hz range. |
| Power consumption | Maximum power draw: • 349W with all 64 ports operating at 64G (48 ports populated with 64G SWL transceivers and 8 ports populated with 2x64G SFP-DD SWL transceivers). • 57W for an empty chassis with no transceivers. Typical power draw: • 155W for Brocade G720 switch with 32 64G SW optics modules under 50% traffic rate. • 252W for Brocade G720 switch with 64 64G SW optics modules under 50% traffic rate. |
