Spanning (JBOD):
JBOD stands for "Just a Bunch of Disks". Each drive is accessed as if it
were on a standard SCSI host bus adapter. This is useful when a single
drive configuration is needed, but it offers no speed improvement or fault
tolerance.
Features and Benefits
Uses: JBOD works best if you have odd sized drives and you
want to combine them to make one big drive.
Benefits: JBOD provides the ability to combine odd size drives
using all of the capacity of the drives.
Drawbacks: Decreases performance because of the difficulty in
using drives concurrently.
Fault Tolerance: No.
