SPAN (JBOD)
With SPAN disk array, the data capacity is eq uivalent to the sum of all h ard disks
used. These hard disks can be of different sizes. The operating system treats the
hard disk drives as if they were one hard drive.
"Spanning" me ans that the data is store d on a hard disk drive until this is full. As soon as
the hard drive is full, the data con tinues to be stored on the next hard disk drive in the
disk array. If one hard drive fails, the entire disk array is affected. SPAN (JBOD ) actually
does not belong to RAID and does not support any error tolerance.
