Maximum Queued I/O Count

The "Maximum Queued I/O Count" menu option enables you to configure the
maximum number of I/O operations per host channel that can be accepted from
servers. The predefined range is from 1 to 1024 I/O operations per host channel, or
you can choose the "Auto" (automatically configured) setting. The default value is
256 I/O operations.
The appropriate "Maximum Queued I/O Count" setting depends on how many I/O
operations the attached servers are performing. This can vary according to the
amount of host memory present as well as the number of drives and their size. If you
increase the amount of host memory, add more drives, or replace drives with higher
performance, you might want to increase the maximum I/O count. But usually,
optimum performance results from using the "Auto" or "256" settings.
For more information, please refer to the Firmware Manual that came with your
system.
