Fabric Port Overview
All ports on the SANbox-16HA chassis are “Loop-aware” FL_Ports. That is, they
are ports that are able to discover, through the Fibre Channel Fabric Login process,
whether they should function as an F_Port (communicating with an N_Port) or as a
Fabric Loop port (communicating with an Node Loop Port (NL_Port)). Fabric
ports connect to Public devices that conform to the Fibre Channel Standards.

Switch management allows you to force a fabric port to function as an F_Port.

Segmented Loop Port (SL_Port) Overview
You may use Switch management to configure any or all ports on the SANbox-16
chassis as Segmented Loop ports (SL_Ports). SL_Ports connect to devices which
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA)
standard. SL_Ports allow you to divide these Private Loops into multiple segments
which may communicate through the Switch as though they were all part of the
same Private Loop.

which may communicate through the Switch as though they were all part of the

A Segmented Loop has greater performance than an un-segmented loop because a
Segmented Loop can have multiple concurrent frame transfers (one per loop
segment) while an un-segmented loop can have only one.
