both host I/O and verify tasks. The Low Latency setting minimizes latency
(delay) in reading data from a RAID unit by slowing down the verify task
process. For some applications, such as video server applications and audio
applications, it is important to minimize the latency of read commands, so that
users do not perceive a lag when viewing video or listening to audio.
For a more complete discussion of background task modes, see “Working
with the Background Task Mode” in the 3ware SATA+SAS RAID Controller
Card Software User Guide, Version 10.0
Example:
//localhost> /c1 show verifymode
/c1 Verify background task mode = Low Latency

show verifyrate
This command shows the current verify task rate of the specified controller.
The verify task rate sets the verify execution priority relative to I/O
operations.
This task rate is of the range [1..5], where 5 denotes the setting of fastest
background task and slowest I/O, as follows:
5 = fastest verify; slowest I/O
4 = faster verify; slower I/O
3 = balanced between verify and I/O
2 = faster I/O; slower verify
1 = fastest I/O; slowest verify
This command applies to the 7000, 8000, and 9000 models controllers.
Example:
//localhost> /c1 show verifyrate
/c1 Verify task rate = 4 (faster verify; slower I/O)
