HP Surestore Tape Library Model 20/700 Installation Instructions Manual page 4

Library Drive Attachment
Tape drives are shipped individually. Due to the size differences of the DLT and 9840
drives, there are a variety of ways of installing the drives. Typically, drive installation moves
from the bottom slot and up.
Refer to Figure 1 and the explanation below for the configuration rules for installing drives.
1. The first callout in Figure 1 shows that the uppermost drive slot in the drive column can only be a
DLT drive.
2. The second callout depicts the size ratio of the 9840 drives to the DLT drives. In size, two
9840 drives fit in the same space as three DLT drives.
3. The third callout shows this ratio again: three DLT drives fit in the same space as two 9840
drives.
4. The fourth callout depicts a mixture of 9840 and DLT drives.
You may also install six 9840 drives plus one DLT drive in a column, where the DLT
drive occupies the top drive slot.
The following table lists the available combinations for one drive column.
