Fibre Channel Topologies - Rorke Data Galaxy 16i User Manual

NOTE:
LC connectors are small form factor, fiber-optic connectors based
on a 1.25-mm ceramic ferrule and the familiar latching
mechanism of the RJ-45 modular plug and jack.
Other beneficial features for a typical SFP transceiver include a
single power supply and low power dissipation. It is also
preferable that these transceivers are hot-swappable. It is also
important that any transceiver you use meets the Fibre Channel
Performance and reliability specifications.

4.2.4 Fibre Channel Topologies

The Fibre Channel Standard has been designed to support three
separate topologies.
arbitrated loop (FC-AL) and fabric switch topologies.
•
Point-to-Point: Point-to-point topology is the simplest
topology that can be used. It is a direct connection between
two fibre channel devices.
•
FC-AL: This is the most common topology currently in use.
Fibre channel devices are all connected in a loop. Each
device is assigned an arbitrated loop physical address
(AL_PA). The FC-AL is able to support 127 devices in a
single loop.
•
Fabric: The fabric topology can support up to 2
channel devices. This topology allows many devices to
communicate at the same time. To implement this topology a
fibre switch is required.
The Galaxy 16i FC models are all able to support the three
topologies discussed above.
