Optimizing Performance

The Adaptec Ultra320 SCSI Bus Master firmware increases the

SCSI performance of the Adaptec Ultra320 host adapters under

multitasking environments. The firmware uses a paging

mechanism to handle up to 255 simultaneous SCSI commands. The

sequencer can simultaneously manage up to 128 tagged, or 1

nontagged, SCSI commands for each SCSI device, up to a limit of

255 SCSI commands. The firmware can queue as many commands

as the operating system is able to send to the host adapter. To set

this feature, enter the following command:

max_tags=n

In general, a low number of max_tags gives better sequential

performance, and a high number a better random performance.

Note: A large number of max_tags can also cause starvation

problems leading to deactivation with some drives.
