The controller continually reevaluates whether to transfer data from disk to its local cache in increments equal to the stripe size or in increments equal to the system I/O request size.
If you have the controller and firmware for adaptive read-ahead mode installed, the Adaptec Storage Manager reports Adaptive on the controller properties pane. Otherwise, the properties pane states either Enabled or Disabled.
Note: You can override Adaptive read-ahead,
but not through the Adaptec Storage Manager. Instead, use the Command Line Interface (CLI) included on the
Adaptec RAID Installation CD.
