Read-ahead cache limit—Enter the desired read-ahead limit (0-16). If
you enter 0, the read-ahead is disabled. Each increment equals 32 blocks
of data that are read ahead in the cache. For example, 2 would equal
64 blocks read-ahead.
■ Controller mode—Shows the controller mode, which is active or
unavailable.
■ Rebuild rate—Enter the desired rebuild rate, which ranges from
1 to 100. The controller rebuilds while it handles I/O activity. A rate

50 puts a higher priority on the RAID rebuild at the expense of I/O
activity.
■ Create rate—Enter the desired create rate, which ranges from 1 to 100.
The controller creates RAID sets while it handles I/O activity. A rate
below 50 emphasizes I/O response over the RAID set creation. A rate
above 50 puts a higher priority on the RAID set creation at the expense
of I/O activity.

CR3500 RAID Controller.
