3.3.2.2 SCSI / Fibre Params MENU

The SCSI / Fibre Params menu configures the SCSI/Fibre portion of the 

SurfRAID 

LC16 subsystem. The

SCSI ID and the termination must be set to avoid causing a conflict with the SCSI adapter or other
SCSI device daisy chained with the 

SurfRAID 

LC16. Command Tag Queuing is a function that allows a

SCSI device to queue multiple requests without having to serialize the operations. This frees the control-
ler to process requests in whatever order is convenient, instead of blindly processing and acknowledging
each disk operation before starting the next. This allows the 

SurfRAID 

LC16 to efficiently handle multi-

threaded applications that issue multiple disk commands.

A.

The “SCSI Params” consists of two categories. Each category is used to configure an indepen-
dent SCSI channel of the 

SurfRAID 

LC16 subsystem. The following shows both categories. Each

category has sub-menus and options.
