Chapter 2 — Architecture Overview
The relationships between the DBAs and the locations of the drives and
controllers are the same in each main frame and drive expansion frame. In
a multi‐frame library, the frames are numbered sequentially from left to
right when viewed from the front, beginning with the left‐most frame
(FR1).
Figure 16 shows the relationship between the DBAs and the locations of
the drives and controllers in the main frame.

identifiers in the BlueScale and XML interfaces (main frame with RIMs shown).

All component identifiers are numbered consecutively by

type, starting at 1.
DBAs are numbered from the bottom up, with DBA 1 being
the bottom‐most.
Drives are numbered from left to right and bottom to top in a
DBA, as viewed from the back of the library. Each DBA can
hold up to four full‐height drives.
If the frame contains DBAs and shelves, the DBAs are installed
from top to bottom with shelves below.
