The DS8800 and DS8700 LFF (3.5") storage enclosure slots are numbered left to
right, and then top to bottom, so that the top row of drives is D01-D04, the second
row is D05-D08, the third row is D09-D12, and for the DS8700, the fourth row is
D13-D16. The DS8800 SFF (2.5") storage enclosure slots are numbered from left to
right as slots D01-D24. For full drive sets, the first installation group populates as
D01-D08 for both enclosures of the pair. The second installation group is D09-D16,
and for the DS8800, the third installation group populates as D17-D24. For half
drive sets, the first installation group populates as D01-D04 of both enclosures in
the pair and the second installation group populates as D05-D08 of both
enclosures, and so on.
Note: Keep in mind that DS8800 storage features are installed from the bottom up
within a unit, while DS8700 storage features are installed from the top down
within a unit.
