System Architecture

Fibre Channel Ports

Switch mode (default): Minimum of 24 ports and maximum of 56 ports. Ports are enabled in increments of 8 ports up to 56 ports via Ports on Demand (PoD) licenses; E_Ports, F_Ports, M_Ports, D_Ports, EX_Ports.Brocade.

Access Gateway default port mapping: 56 SFP+ F_Ports, 8 SFP+ N_Ports.

The SFP+ ports are capable of auto-negotiating to 8, 16, 32, or 64Gb/s speeds depending on the SFP+ model and the minimum supported speed of the optical transceiver at the other end of the link.

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

Non-blocking architecture with wire-speed forwarding of traffic:

8GFC: 8.5 Gb/sec line speed, full duplex

10GFC: 10.53Gb/s line speed, full duplex; 10Gb/s optionally programmable to fixed port speed.

16GFC: 14.025 Gb/sec line speed, full duplex

32GFC: 28.05 Gb/sec line speed, full duplex

64GFC: 57.8 Gb/sec line speed, full duplex

Traffic load balancing

Frame-based ISL Trunking load balances supports up to eight SFP+ ports per ISL trunk; up to 512Gb/s per ISL trunk when using 64Gb/s optics

Dynamic Path Selection (DPS) provides exchange-based load balancing across all available ISLs.

Aggregate bandwidth

3.584Tb/s

Maximum fabric latency

Latency for locally switched ports is 460 ns (including FEC).

Maximum frame size

2112-byte payload

Frame buffers

24K per switching ASIC

Classes of service

Class 2, Class 3, Class F (inter-switch frames)

Port types

D_Port (ClearLink® Diagnostic Port), E_Port, EX_Port, F_Port, M_Port

Optional port-type control

Brocade Access Gateway mode: F_Port and NPIV-enabled N_Port

Data traffic types

Fabric switches supporting unicast

Media types

64Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 64Gb/s SWL.

32Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 32Gb/s SWL, LWL 10 km, ELWL 25 km.

10Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 10Gb/s SWL, LWL 10 km.

Fibre Channel distance is subject to fiber-optic cable and port speed.

USB port

One standard USB port for firmware download, support save, and configuration upload or download.

Fabric services

Fabric Vision; Monitoring and Alerting Policy Suite (MAPS); Flow Vision; Brocade Adaptive Networking (QoS); Fabric Performance Impact (FPI) Monitoring; Slow Drain Device Quarantine (SDDQ); Brocade Advanced Zoning (default zoning, port/WWN zoning, broadcast zoning, peer zoning, target-driven zoning); Dynamic Fabric Provisioning (DFP); Dynamic Path Selection (DPS); Brocade Extended Fabrics; Enhanced BB Credit Recovery; FDMI; Frame Redirection; Frame-based Trunking; FSPF; Integrated Routing; IPoFC; Brocade ISL Trunking; Management Server; NPIV; Time Server; Registered State Change Notification (RSCN); Reliable Commit Service (RCS); Simple Name Server (SNS); Virtual Fabrics (Logical Switch, Logical Fabric); Read Diagnostics Parameter (RDP).

Access Gateway mode: Some fabric services do not apply or are unavailable in Access Gateway mode.

Extension

Fibre Channel, in-flight compression (Brocade LZO) and encryption (ES-GCM-256 encryption on FC ISLs, E_Port); integrated optional 10Gb/s Fibre Channel for DWDM MAN connectivity.

Power supplies

Dual, hot-swappable redundant power supplies (80 PLUS Gold) with integrated system cooling fans (3 built into each power supply), N+N cooling redundancy.

Management

Supported management software

HTTP; SNMP v1/v3 (FE MIB, FC Management MIB); SSH; Auditing; Syslog; NTP v3; Brocade Advanced Web Tools; Brocade SANnav Management Portal and SANnav Global View (optional license); EZSwitchSetup; Command Line Interface (CLI); SMI-S compliant; REST API; Administrative Domains; trial licenses for add-on capabilities.

Security
