Q-Logic 16HA Manuel D’Utilisation

•

You may populate 2 to 16 ports with GBICs. The choice of ports and GBICs 
is yours.

The Switch has been validated with GBICs that support a variety of intercon-
nection media. Refer to 

 for more infor-

mation.

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. 
Refer to the Switch Management manual for more information.

The attributes of F_Ports and FL_Ports are described in the Fibre Channel 
Standards.

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.

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.
