Recording format and media support for TS1140 tape drives

The TS1140 tape drive reads and writes in the new EFMT4 (enterprise format 4) and EEFMT4 (enterprise encrypted format 4) recording formats (MEDIA9 through MEDIA13), as well as the existing EFMT3 (enterprise format 3) and EEFMT3 (enterprise encrypted format 3) recording formats (MEDIA9 and MEDIA10). The TS1140 tape drive can also read (but not write) the older EFMT2 and EEFMT2 recording formats (MEDIA9 and MEDIA10), and media types MEDIA5 through MEDIA8 (EFMT1, EFMT2, EEFMT2, EEFMT3, and EEFMT3). EEFMT4 records data in an encrypted format. EEFMT4 provides the same capacity as EFMT4.

Ensure that any partially filled MEDIA9 or MEDIA10 tapes written in EFMT2 or EEFMT2, and MEDIA5 through MEDIA8 tapes written in EFMT1, EFMT2, EEFMT2, EFMT3, or EEFMT3 are marked-full (as appropriate), because they cannot be extended on the TS1140.

The IBM System Storage TS1140 tape drive uses the following IBM System Storage family of tape media.

MEDIA9 - The IBM Enterprise Extended Tape Cartridge (MEDIA9) physical media. MEDIA9 requires the EFMT4, EFMT4, EFMT3, or EEFMT3 recording format, and provides an uncompressed capacity of 1600 GB with EFMT4 or EEFMT4 (1000 GB with EFMT3 or EEFMT3). Provides a compressed capacity of 4800 GB with EFMT4 or EEFMT4 (3000 GB with EFMT3 or EEFMT3), assuming a 3:1 compression ratio (the compression ratio depends on the type of data written). Read-only for EFMT2 and EEFMT2.
MEDIA10 - The IBM Enterprise Extended WORM Tape Cartridge (MEDIA10) physical media. The MEDIA10 capacity is the same as the MEDIA9 capacity.
MEDIA11 - The IBM Enterprise Advanced Tape Cartridge (MEDIA11) physical media. MEDIA11 requires the EFMT4 or EEFMT4 recording format, and provides an uncompressed capacity of 4000 GB. Provides a compressed capacity of 12000 GB, assuming a 3:1 compression ratio (the compression ratio depends on the type of data written).
MEDIA12 - The IBM Enterprise Advanced WORM Tape Cartridge (MEDIA12), physical media. The MEDIA12 capacity is the same as the MEDIA11 capacity.
MEDIA13 - The IBM Enterprise Advanced Economy Tape Cartridge (MEDIA13) physical media. MEDIA13 requires the EFMT4 or EEFMT4 recording format, and provides an uncompressed capacity of 500 GB. Provides a compressed capacity of 1500 GB, assuming a 3:1 compression ratio (the compression ration depends on the type of data written). For this media type there is equivalent WORM cartridge.

You can use the TS1140 tape drive in the stand-alone environment or the tape library environment (automated or manual). Currently, the TS1140 tape drive does not have a cartridge loader.

Support for the TS1140 tape drive will be provided at z/OS V1R11 and later releases

Note:

If no recording technology has been specified for MEDIA9, MEDIA10, MEDIA11, MEDIA12, or MEDIA13, EFMT4 is the default recording technology. Other recording formats (EFMT3, EEFMT3, or EEFMT4) can be specified through data class. This applies to both the stand-alone and to the system-managed tape library environments. However, with the TS1140, EFMT3 and EEFMT3 are supported only with MEDIA9 and MEDIA10.
To enable the EFMT4 and EEFMT4 formatted cartridges (MEDIA9 and MEDIA10) to be relabelled/reused from load point on a 3592 Model E05 (3592-2 and 3592-2E) or on a 3592 Model E06 (3592-3E), drive microcode updates are required on these drives. This is particularly important in a system-managed tape library environment, because common scratch pools are used across the media types.
For an encrypted tape cartridge, the cartridge stores both the encrypted user data and the critical key management-related information needed to interact with the encryption key manager when decrypting data on the cartridge. A mix of data written in encrypted and non-encrypted formats is not supported on the same tape cartridge. Whether the data on a cartridge is written in encrypted format is determined during OPEN processing, when the first file sequence on the tape is written. If the first file written to a tape is in the encrypted format; all subsequent files written to that same tape cartridge will be written in the encrypted format. All files written to a cartridge in the encrypted format are encrypted using the same data key. The exception to this is the volume label structure for the first file sequence, which is encrypted using a key known to all encryption capable 3592 drives, which means it is effectively in the clear.
The TS1140 tape drive optionally provides performance scaling by using only 20 percent of the full capacity on a MEDIA9 or MEDIA11 cartridge. The default is to use the cartridge's full capacity. The performance scaling option is not available with the economy or WORM media type.
The TS1140 tape drive optionally provides performance segmentation. Performance segmentation divides the cartridge into a fast access segment and a slower access segment. The fast access segment will be filled first, after which the slower segment will be filled. This option is available on MEDIA9 and MEDIA11 tapes. The performance segmentation option is not available with the economy or WORM cartridge. The performance segmentation option is mutually exclusive with the performance scaling option.
The TS1140 tape drive emulates only 3590 Model B1x tape drives in the standalone and in the system-managed tape library environment (manual or automated).
The TS1140 tape drive is supported by the 3592 Model C06 tape controller (ESCON® or FICON® attachment) and with the C07 tape controller (FICON-only attachment). It is not supported with the older J70 tape controller.
The TS1140 (3592 Model E07) tape drive is not supported in the older 3494 automated tape library.
The TS1140 (3592 Model E07) tape drive coexists with 3592 Model J1A, 3592 Model E05 (3592-2 and 3592-2E), and 3592 Model E06 (3592-3E) devices in the 3584 automated tape library.
The TS1140 (3592 Model E07) tape drive coexists with 3490, 3490E, 3590, 3592 Model J1A, 3592 Model E05 (3592-2 and 3592-2E), and 3592 Model E06 (3592-3E) devices in a manual tape library.
The TS1140 tape drive cannot use the MEDIA3 or MEDIA4 cartridges used in 3590 tape drives, nor can it write to the older 3592 media types (MEDIA5, MEDIA6, MEDIA7, or MEDIA8).
For the system-managed tape library support (automated or manual), even though a mix of 3592 tape drives (different models) is supported under a single control unit, with z/OS system-managed tape library support, all devices under the same control unit must be homogenous and support the same capabilities. So, although a mix of 3592 tape drives is supported within the same library, within each control unit, all the devices must be either TS1140 tape drives (only) or TS1130 tape drives (only) or TS1120 tape drives (only). In addition to this, all TS1120 tape drives must also be homogeneous so a mix of encryption and non-encryption capable drives is also not supported within a control unit.
