This section covers:
Supported Tape Drives
These tape drives are supported for a connection to a CTL700 tape library:
•
CT9840-1 tape drive
•
CT9840FC-1 tape drive
•
5259 tape drive
•
N1521A tape drive
•

The supported tape drives and their respective power supplies are field-replaceable
units (FRU). Contact your service provider if the tape drives require servicing.
The CTL700 tape library can accommodate up to twelve CT9840-1/CT9840FC-
1/CT9841FC-1 tape drives, up to twenty 5259 tape drives, up to twenty N1521A tape
drives, and up to twenty M8503 tape drives. A combination of all these tape drives can
be configured.
Data Compression
The supported tape drives can write compressed or uncompressed information to a
labeled or unlabeled tape cartridge. Compression increases the cartridge capacity
(over the uncompressed format) by two to three times.
Writing compressed data on a tape cartridge means the tape drive compresses data
whenever possible. The specific amount of data stored on the tape cartridge is not
predictable because the amount of compression varies with the type of data being
written. For this reason, the amount of compressed data stored on tape cartridges can
vary significantly.
