Spanning
In a Spanning array, the disk array capacity is equal to the sum of all drives, even if
the drives are of different capacities. Spanning stores data onto a drive until it is
completely filled, then proceeds to store data on to the next drive in the array .
There are no performance or fault tolerance array features in this type of array.
When a disk member fails, the entire array is offline.
