Rack-mount design (1U form factor) using existing rail kits (fixed and mid-mount/Telco rail kits)
on a 19-inch EIA rack.
Extensive diagnostics and system-monitoring capabilities for enhanced high Reliability,
Availability, and Serviceability (RAS).
The Brocade EZSwitchSetup wizard that makes SAN configuration a three-step point-and-click
task.
FCoE to FC latency of 1670 nanoseconds.
24 ports 10 GbE CEE.
Low latency, lossless, deterministic interconnect required for FCoE.
FCoE support along with Fabric Provided MAC Address (FPMA) discovery. FOS delivers these
features and also enables support for Priority-based Flow Control (802.1Qbb). Data Center
Bridging eXchange (DCBX) - Capabilities Exchange and Enhanced Transmission Selection
(802.1Qaz) delivers the lossless and deterministic FCoE requirement.
Enables hardware-assisted MAC learning and aging.
Support for 32K MAC addresses and 4K Vlans.
Support for Layer 2 protocols STP/MSTP/RSTP (802.1q) and Link Aggregation (802.1ad).
Brocade 10G SFP+ (SR and LR) and Brocade-branded Twinax copper cables.
CEE port to CEE port latency of 570 nanoseconds (same ASIC) and 1050 nanoseconds
(different ASIC).
Up to 8 auto-sensing ports of high-performance 8 Gbps technology in a single domain.
Full 1:1 subscription on 8 Gbps ports.
1, 2, 4, and 8 Gbps auto-sensing Fibre Channel switch and router ports.
Universal ports self-configure as E, F, M, or FL ports.
Inter-Switch Link (ISL) Trunking (licensable), which allows up to eight ports (at 1, 2, 4, or 8 Gbps
speeds) between a pair of switches combined to form a single, logical ISL with a speed of up to
64 Gbps (128 Gbps full duplex) for optimal bandwidth utilization and load balancing.
Dynamic Path Selection (DPS), which optimizes fabric-wide performance and load balancing by
automatically routing data to the most efficient available path in the fabric.
Brocade-branded SFP optical transceivers that support any combination of Short Wavelength
(SWL) and Long Wavelength (LWL) optical media among the switch ports.
Support for unicast, multicast (255 groups), and broadcast data traffic types.
