EMC Fibre Channel Storage-System Configuration Planning
About Fibre Channel Storage Systems and Networks (SANs)
If your servers and storage systems will be far apart, you can place
the switches closer to the servers or the storage systems, as
convenient.
A switch is technically a repeater, not a node, in a Fibre Channel loop.
However, it is bound by the same cabling distance rules as a node.
Fibre Channel Hubs A hub connects all the nodes cabled to it into a single logical loop. A
hub adds serviceability and scalability to any loop; it allows on-line
insertion and removal of any device on the loop and maintains loop
integrity if any connected device stops participating.
Fibre channel hubs are compact units that fit in 1 U (1.75 inches) of
storage space. They are available to fit into a rackmount cabinet or as
small deskside units.
Figure 1-6 Nine-Port Hub
If your servers and storage systems will be far apart, you can place
the hubs closer to the servers or the storage systems, as convenient.
The nine-pin port can connect to a server,
storage system, or another hub.
