IBM TS3100 Technical Information page 4

• Increased tape cartridge capacity: LTO Generation 7 media specification tape
cartridge physical capacity is up to 15 TB compressed physical capacity, more
than double that of the Ultrium 6 data cartridges. This is achieved by increasing
the linear density, track density, and the media length. The tape itself is a Barium
Ferrite tape developed to help provide durability and increased capacity.
• Ultrium 6 cartridge compatibility: The Ultrium 7 tape drive can read and write
Ultrium 6 cartridges.
• Encryption supported on Ultrium 7, 6, 5, and 4 Fibre Channel and
SAS tape drives: The IBM TS3100 and TS3200 Tape Libraries support data
encryption on the base drive with LTO 7, 6, 5, and 4 media meeting LTO
Generation 7 media specifications and application-managed encryption. System
Managed and Library Managed Encryption are supported with the Transparent
LTO Encryption feature number 5900. IBM Security Key Lifecycle Manager V1 is
required with this feature.
• Attachment options: The TS3100 and TS3200 Tape Libraries come with
dual port 6 Gbps SAS or single port 8 Gbps Fibre Channel LTO-7 tape drive
attachment for connection to a wide spectrum of open system servers. They are
supported on IBM Power Systems, System p, System z, Microsoft
Linux, and other open systems.
• WORM media support: With LTO Generation 7 media specification of up
to 15 TB with 2.5 to 1 compression, IBM 3589 LTO-7 WORM tape cartridges
are designed for archiving and data retention applications, as well as those
applications requiring an audit trail. These cartridges work with the IBM LTO
Ultrium 7 tape drive to help prevent the alteration or deletion of user data. IBM
LTO-7 WORM tape cartridges can be ordered as unique 3589 models with the
following features:
– Color coding and prelabeling with the ability to specify a starting volume serial
– Packaging in individual jewel cases or in bulk
– Cartridge memory is built into every cartridge to enhance functionality and
media reliability by storing access history and media performance information
for use by the tape drive every time the cartridge is accessed
– Half-inch Barium Ferrite tape with up to 15 TB WORM compressed capacity in a
single cartridge
• Larger internal data buffer: There is a 1 GB internal data buffer in the Ultrium
7 full-high and half-high tape drive.
• Digital speed matching: Speed matching on Ultrium 7 ranges from 100 to up
to 300 MB/sec versus 40 to up to 160 MB/sec on Ultrium 6.
• Giant Magneto Resistive (GMR) head design: Use of flat lap head technology
in GMR heads from the Enterprise tape drives for Ultrium 7 helps minimize
contact, edge damage, debris accumulation, and wear on the tape as it moves
over the read/write heads.
• Dual-stage 32-channel head skew actuator: The actuator is designed to
provide precision head alignment to help support higher track density and
improved data integrity. The track following skew actuator supports flangeless
tape guide rollers and dynamic skew to enable the head to follow skew tape
motion and improve linear actuation.
• Power management: The Ultrium 7 tape drive power management function is
designed to control the drive electronics to be either completely turned off or in a
low-power mode when the circuit functions are not needed for drive operation.
Proven IBM LTO Ultrium features in the IBM LTO Ultrium 7 tape drive include:
• Servo and track layout technology: There are 3,584 data tracks in Ultrium 7
versus 2,176 data tracks in Ultrium 6. The high-bandwidth servo system features
a low-mass servo to help more effectively track servo bands and improve data
throughput with damaged media in less-than-optimal shock and vibration
environments.
• Surface Control Guiding Mechanism: The patented Surface Control Guiding
Mechanism from IBM is designed to guide the tape along the tape path in the
Ultrium 7, 6, 5, and 4 tape drive. This method is designed to use the surface of
the tape, rather than the edges, to control tape motion to reduce tape damage
