Fabric OS Native and Access Gateway modes
1
Fabric OS Native mode
The Embedded Switch Module has the following features when operating in Fabric OS Native mode:
• Up to 8 external autosensing Fibre Channel ports (up to 8 Gbps). These universal and
self-configuring ports are capable of becoming one of the following port types:
- F_Port (fabric enabled)
- FL_Port (fabric loop enabled)
- E_Port (expansion port)
These ports are capable of Brocade ISL Trunking with appropriate licensing.
• Up to 18 internal copper backplane F_Ports. Each port can automatically negotiate its speed at
4 or 8 Gbps to match the highest speed supported by the attached devices.
The internal copper F_ports are hard-wired to the blade server chassis backplane, with an
internal connection to the server blades installed in the chassis.
• Dynamic ports on demand, which allows ports to be activated as needed based on available
licenses. This also applies to Access Gateway mode.
• Frame filtering that augments the hardware zoning capabilities of the Brocade ASIC, which
implements hardware zoning at the port level of the Embedded Switch Module. The single
switch ASIC design eliminates blocking, guaranteeing full transmit and receive bandwidth to all
Fibre Channel ports at all times.
• Brocade ASIC expanded capabilities, including World Wide Name (WWN), device-level,
protocol-level, and Logical Unit Number (LUN)-level zoning to provide the flexibility of
second-generation software zoning with the enhanced security of hardware zoning.
• Hardware zoning implemented by firmware-accessible table per output port, which permits or
denies delivery of frames to any particular destination port address.
• Extensive diagnostics, system-monitoring, and reliable power and cooling capabilities. This
also applies to Access Gateway mode.
• Unicast and broadcast data traffic support.
• Up to eight Brocade-branded small form-factor pluggable (SFP) optical transceivers. The SFP
optical transceivers support any combination of Short Wavelength (SWL) and Long Wavelength
(LWL) optical media.
You can add additional transceivers by purchasing them separately from your vendor.
