RAID Techniques and Terms
The techniques of disk striping, mirroring, and parity (redundancy) are
fundamental elements of RAID technology performed by the DAC960PG.
More detailed information on how to apply these techniques can be found in
the
DACCF Utilities Installation Guide and User Manual
. or the
GAM
manual.
JBOD (No RAID)
JBOD is an acronym for Just a Bunch Of Disks. The disks function
independently of one another, just as they would on a non-RAID SCSI
controller.

Mirroring (RAID 1)
Mirroring refers to the 100% duplication of data from one disk drive onto
another. Each disk contains the mirror image of the data on the other drive.
