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.
