The 7206 family of tape drives are externally attached 4mm streaming tape drives
designed for use with IBM RS/6000 workstations and servers.
Both of the 7206 tape drives incorporate
increasingly sophisticated technology and higher performance. All models use
Digital Audio Tape (DAT) / Digital Data Storage (DDS) tape technologies. The
tape capacity, transfer rate, and reliability of the 7206 make it an excellent
choice for backup, restore and archiving operations.
The Model 110, DDS-3, takes
advantage of tape formatting efficiencies extending the cartridge capacity
up to 12GB* and adding new reliability and performance features.
The Model 220, DDS-4,
improves cartridge capacity up to 40GB* by implementing Metal Particle 3
(MP+++) tape technology as well as improved reliability features and
enhanced data transfer rate.

Many of the 1,000,000 installed RS/6000's and pSeries servers (over 100,000 !) are
configured with internal DDS Internal 4mm tape drive technology. These users can
take advantage of new DDS functionality. Each of the 7206 tape drives are
backward read and write compatible for two previous generations of DDS tape
cartridges. Investment protection is provided by this enhanced migration and
data interchange capability. An upgrade to a 7206 provides improved capacity,
advanced performance and a new level of reliability for a reasonable cost.
Model 110
Data storage capacity of 4GB to 12GB* (8GB to
24GB* with 2:1 data compression)
Data transfer rate from 400KB to 1.1MB/sec
(800KB to 2.2MB/sec with compression)
Read and write in DDS-1, DDS-2 and DDS-3 tape
cartridges providing for ease of migration and interchange
Media recognition feature which allows only
data grade tape cartridges to be used for writing data
DDS-3 technology offering improved
read-channel performance, enhanced self-cleaning technologies, energy saving
features, and fewer components

The IBM 7206 Model 110 external 4mm DDS-3 tape drive,
specifically adapted for the RS/6000 environment, continues in the tradition of
an excellent streaming tape drive ideally suited for backup, restore and archive
operations.
The 7206 Model 110 continues to offer the successful reliability and performance
features provided by the IBM 7206 Model 005. New technologies incorporated
within the Model 110 expand these qualities. For example, availability and
implementation of Metal Particle 2 tape (MP++) results in denser recording of
data, resulting in increased tape storage capacity. With 2:1 compression, an
effective cartridge capacity of up to 24GB is now realized. Similarly, data
transfer rate of up to 2.2MB/second is attainable. The IBM 7206 Model 110
provides a more cost effective solution for save, restore, and archiving
functions than previous models.
Many benefits are attributed to these new technologies. The increased storage
capacity, three times the capacity of the IBM 7206 Model 005, can reduce the
number of tape cartridges required, resulting in savings in cartridge costs and
tape inventory maintenance. The 7206 Model 110 achieves a new level of
reliability by incorporating a media recognition feature which allows only data
grade tape cartridges to be used for writing data. Also provided are improved
read-channel performance, enhanced self-cleaning, energy-saving features, and
fewer components than DDS-2 models. A field-proven mechanism that uses an
electronic tape path to ensure long life for the head, drum and key components
is also featured in the Model 110.
Reading and writing on DDS-3 tape cartridges, as well as
two-generation backward compatible DDS tape cartridges, provides for migration
and data interchange.
Model 220
Data storage capacity of 4GB to
20GB* (8GB to 40GB* with 2:1 data compression)
Data transfer rate from 400KB to
3.0MB/sec (800KB to 6.0MB/sec with compression)
Read and write in DDS-2, DDS-3
and DDS-4 tape cartridges providing for ease of migration and interchange
Non-data grade media rejection
which will not permit writing on audio-grade media
Read after write data
verification which ensures that data is written accurately
File access average search speed
of 40 seconds on any part of a DDS-4 tape

The IBM 7206 Model 220 External
4mm DDS-4 Tape Drive provides the advanced performance, improved capacity,
and high reliability demanded in a data storage solution for the IBM RS/6000
family of workstations and servers. Adapted to specifically exploit RS/6000
manageability features, this streaming tape drive is ideally suited for
critical backup, restore and archive operations.
Technology enhancements to Digital Data Storage (DDS) technology continue
and are implemented in the IBM 7206 Model 220. Metal Particle 3 tape
(MP+++), implemented in DDS-4 tape technology, is manufactured with a
flexible and corrosion resistant magnetic coating which extends tape storage
life. Additionally, thinner tracks on the tape allow for increased tape
storage capacity. With 2:1 compression, cartridge capacity is increased up
to 40GB per cartridge, and a sustained data transfer rate of up to 21.6 GB
per hour is possible. The attributes of the low-cost, high capacity tape
cartridge combined with the performance characteristics of the 7206 Model
220 DDS-4 Tape Drive provide an excellent price/capacity proposition.
These factors provide many benefits. Maintenance of tape inventory as well
as tape costs may be reduced as a result of the higher capacity tape
cartridges. The enhanced data transfer rate, nearly three times faster than
the IBM 7206 Model 110 DDS-3 Tape Drive, saves operator time. Engineering
enhancements such as a simplified tape path, improved air flow, and
automatic drum and head cleaning contribute to the drives high reliability.
Data integrity is enhanced with non-data grade media rejection and read
after write data verification.
Reading and writing on DDS-4 tape cartridges, as well as two-generation
backward compatible DDS tape cartridges (DDS-2 and DDS-3), provides for
migration and data interchange
