4.3.3 SCSI Params menu
The SCSI Params menu configures the SCSI portion of the ACS-8910 controller. The SCSI ID and
the termination must be set to avoid causing a conflict with the SCSI adapter or other SCSI devices
daisy chained with the ACS-8910. Command Tag Queuing is a function that allows a SCSI device to
handle multiple requests without having to serialize the operations. This frees the disks to process
requests in whatever order is convenient, instead of blindly processing and acknowledging each disk
operation before starting the next. This allows the ACS-8910 to efficiently handle multithreaded
applications that issue multiple disk commands.
