Rules for disk drive population
As described in the previous paragraph, disks are arranged in six rows of twenty modules
each. The first (front) row is denoted as A, then the remaining rows are B, C, D, E, and F. In
each row, the disks are numbered with the first disk labeled with a letter and number
together, for example A0 or A19, and so on (for more information, refer to
layout" on page 108).
The required order of loading the disk drives into a 3U, 120 DAE is as follows
page 108):
1. Start at row (or bank) A, slot 0 or A0.
2. Fill up the row (or bank) A before inserting any disk drives into row B.
3. Continue this order until you fill all the rows with row F being the last row filled.
Note: If you partially fill a row, fill the remaining empty slots with filler panel modules.
Rows with no or zero (0) drives do not require filler panel modules.
