No-Read-Aheadspecifies that the controller does not use read- ahead for the current logical drive.

Read-aheadspecifies that the controller uses read-ahead for the current logical drive.

Adaptive specifies that the controller begins using read-ahead if the two most recent disk accesses occurred in sequential sectors. If all read requests are random, the algorithm reverts to No-Read- Ahead, however, all requests are still evaluated for possible sequential operation. This is the default setting.

19Set the Cache Policy.

Cache Policy applies to reads on a specific logical drive. It does not affect the read ahead cache.

Cached I/O specifies that all reads are buffered in cache memory.

Direct I/O specifies that reads are not buffered in cache memory. This is the default setting. Direct I/O does not override the cache policy settings. Data is transferred to cache and the host concurrently. If the same data block is read again, it comes from cache memory.

20Press <Esc> to exit the Advanced Menu.

21After you define the current logical drive, choose Accept and press <Enter>.

If space remains in the arrays, the next logical drive to be configured appears.

22Repeat steps 3 to 22 to create an array and configure another logical drive.

If the array space has been used, a list of the existing logical drives appears.

23Press any key to continue and respond to the Save prompt.
