Modify RAID Group Parameters
This function tunes RAID group performance by specifying the Disk Command Multiplying Fac-
tors (DCMF) and rebuild priority.
•
DCMF
DCMF is a coefficient for the command issuance amount of the disk. Specify this parameter to
improve the sequential writing access performance. The bigger the value is, the more com-
mands issue. Specify the DCMF according to the RAID group operation.
•
Rebuild Priority
Specify the level to give priority to rebuild, copyback, and redundant copy instead of host
access. Specifying a larger "Rebuild Priority" value may improve redundant copy perfor-
mance.
