or pass-thru mode) to help provide optimal data compression and increase data
throughput. The compression ratio for LTO Ultrium 5 is 2 to 1.
•
LTO-CM:
Contained within the LTO Ultrium data cartridge is the LTO-CM,
which is a passive, contactless silicon storage device that is a physical part of
the cartridge. The LTO-CM is designed to hold information about that specific
cartridge, the media in the cartridge, and the data on the media. The storage
capacity of the Generation 5 and 4 LTO-CM is 8160 bytes. Communication
between the drive and the LTO-CM is through a low-level RF field transmitted by
the drive to the cartridge.
•
SARS:
The Ultrium 5 Tape Drive uses SARS to help isolate failures between
media and hardware. SARS uses the cartridge performance history saved in the
CM module and the drive performance history kept in the drive flash EEPROM to
help determine the most likely cause of failure. SARS is designed to cause the
drive to request a cleaner tape, to mark the media as degraded, and to indicate
that the hardware has degraded.
•
Highly integrated electronics using IBM-engineered copper technology:
This technology is designed to reduce the total number of components in the
drive, help lower chip temperatures, and reduce power requirements to deliver a
more reliable drive. The fifth-generation drive electronics are designed to provide
error correction of soft errors in the memory arrays in data and control paths.
With support for LTO Ultrium-format tape data cartridges, TS1050 Model F5C with
the TS4500 Tape Library can be a cost-effective solution for backup, save-and-
restore, and archiving functions.
Ultrium 5 Data Cartridge
The LTO Generation 5 media specification tape cartridge physical compressed
capacity of the LTO 5 Data Cartridge has more than doubled the capacity of the IBM
Ultrium 4 Data Cartridge with a capacity of up to 3.0 TB with 2 to 1 compression.
IBM LTO Ultrium 5 Tape Drives can read and write Ultrium 4 data cartridges, and
read Ultrium 3 data cartridges. IBM LTO 5 cartridges can be resident in the same
TS4500 tape library with the Ultrium 4 and Ultrium 3 data cartridges. IBM LTO 5
data cartridges can be ordered using IBM machine type 3589, IBM LTO Ultrium Tape
Cartridges.
These cartridges have been designed to provide several enhancements over
previous tape technologies. They are designed to work with tape drives that have
increased tape speeds and high-density data recording. The case is specially
designed for use in automated libraries and is designed for repeated, unattended
handling.
TS1060 Model F6C and TS1050 Model F5C Tape Drive supports IBM LTFS partitioning
which enables data to be written individually on media without affecting data on
another partition.
TS4500 features and functions
LTO tape drives
The TS4500 tape library supports LTO 5 and later LTO tape drives.
The LTO 5 and LTO 6 tape drives are dual-ported drives that facilitate 8 Gbps Fibre
Channel connectivity. These drives are differentiated from other LTO drives by their
machine type and model numbers. You can identify the LTO tape drives by the label
at the rear of the drive's canister. The following two generations of HD2-compatible
LTO drives are supported by the HD2 frames of the TS4500 tape library:
• IBM TS1060 Tape Drive (Model 3588 F6C)
• IBM TS1050 Tape Drive (Model 3588 F5C)
Note:
Drive models 3588 F6A and 3588 F5A are not supported by the HD2 frames
of the TS4500 tape library.
