In some literature Disk Chaining is also called Disk Spanning . You can picture the functio-
ning mechanism of a type Chain Logical Drive as follows: all hard disks forming the Logical
Drive are linked together one by one in the exact same order in which they have been selec-
ted with the <SPACE>-bar. This concatenation can be compared with a chain. If, for ex-
ample, the Logical Drive consists of 4 hard disks with 2000MB each, the Logical Drive will
have a capacity of 8000MB. When data is written to this Logical Drive, the first hard disk is
filled first, then the second, and so on.
Although it is not advisable, Logical Drives of the type Chain, can also be components of
Array Drives.
Select the hard disks with the <SPACE>-bar and then confirm with <ENTER>.
A security request appears. If you confirm with <Y > , GDTSETUP allows you to limit the size
of the Logical Drive. This becomes interesting when you configure later on an Array Drive
with several identical Logical Drives and you want to make sure that you get appropriate
spare hard disks in the future. If you limit from the beginning the capacity to e.g., 8500MB,
you can be sure that all future 9GB hard disk will have at least this capacity and thus can be
used as spare hard disk.
