Volume IO Policy column
|
The method the host operating system can use to access the virtual drive. This can be one of the following:
-
Blocked—The host cannot access the drive.
-
Read-Write—The host has full access to the drive.
-
Read-Only—The host can only read data from the drive.
|
|
Volume Read Ahead Policy column
|
Specifies how the controller uses the read-ahead feature. This can be one of the following:
-
Adaptive—Read-ahead is enabled and used when the controller determines that it will improve the performance.
-
Always—Read-ahead is enabled and always used.
-
None—Read-ahead is disabled.

|
|
Configured Write Cache Policy column
|
Currently running cache policy. This can be one of the following:
-
Write Through—Data is written to both cache and drives. The transaction is not marked as complete until the data is written to the drives.
-
Write Back—Data is stored in the cache and will be written to the drives when bandwidth becomes available. This policy provides higher
write performance than the Write Through mode but reverts to Write Through mode when the battery backup unit (BBU) is defective or in a learn cycle.
-
Write Back Even If Bad BBU—Caching remains in Write Back mode even if the BBU is bad. Data can be lost in this mode if there is a power failure.
