TS1140 tape drive

Unlike the TS1120 (3592 Model E05), which can be either encryption capable (3592-2E) or not (3592-2), the TS1140 (3592 Model E07) is always capable of encryption when used by z/OS and always reports as 3592-4E. References in this document to "encryption-capable" means that the encryption feature in the drive had been enabled and the drive is capable of encrypting. In other documents, this may be referred to as "encryption-enabled".

The TS1140 tape drive offers these features:

Creates tapes for archive files.
Optionally creates encrypted tapes.
Backs up and restores systems in case of system or disk storage problems.
Stores high-speed, high-capacity sequential application data sets.
Stores temporary data sets.
Satisfies off-site data storage for disaster recovery.
Provides data interchange (MEDIA9 and MEDIA10 cartridges) with other systems that use 3592 Model E07 (TS1140) and 3592 Model E06 (TS1130) subsystems. The 3592 Model E07 can also read MEDIA9 and MEDIA10 cartridges written in the EFMT2 and EEFMT2 formats, as well as MEDIA5, MEDIA6, MEDIA7, and MEDIA8 cartridges written in EFMT1, EFMT2, EEFMT2, EFMT3, and EEFMT3 formats.
Supports WORM (write once, read many) tape data cartridges whose data cannot be altered.

The advantages of the TS1140 tape drive over other encryption methods, such as host-based software encryption, are that it:

Permits full performance of the tape device when encryption is enabled.
Permits encryption to be performed after compression.
Avoids performance penalties in the host.
