4.4 Configuring the Controller

RAIDWatch Manager enables you to modify the configuration of the disk array controller from your manager console. You can set caching optimization parameters of the system, set I/O queue limitations, set drive optimization parameters, set RAID verification options, get information about current system and board status, download firmware or NVRAM data to the controller, set redundant controller options, and modify the RAID system password among other variables.

The following is a complete list of configuration controls and information displays (more information about many of these variables is available in the controller hardware and firmware documentation).


4.4.1 Caching

The data cache can be configured for optimal I/O performance using the following variables:
  • Caching Policy (choose one):
Cache Write Back. (Default controller setting.) Recommended operating mode, provides better performance.
Cache Write Through. Used primarily if no cache battery backup is installed and there is increased likelihood of a power failure.
  • Optimization Policy (choose one):

IMPORTANT:

Optimization settings should not be changed after logical drives are created. Under some circumstances, changing the optimization setting after logical drives have been created will destroy existing data on those drives.



4.4.2 Host-Side

Host-side SCSI Parameters (choose from the range):

4.4.3 Drive-Side

Drive Side SCSI Parameters (choose from each range):

4.4.4 RAID

Disk Array Parameters (choose from each range):
