–
No-Read-Ahead specifies that the controller does not use read-
ahead for the current logical drive.
–
Read-ahead specifies 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.
Set the Cache Policy.
19
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.
