Configuring the Controller
Locking the Cache
Some host OSs disable the write-back cache of the controller,
resulting in degraded performance. You can stop this from
happening by enabling the Cache Lock. (The default setting is
Disabled.)
To enable the cache lock:
1 From the System Menu, select Configuration Menu and press
Enter.
The Configuration menu appears.
