General information
The IBM 3447 Digital Linear Tape Library is an automated tape library supported on selected Netfinity(R) server and IBM PC Server systems.

The 3447 Digital Linear Tape Library automates the latest DLT7000 tape drives. It includes one removable 10-cartridge magazine and five fixed cells, yielding a total capacity of 15 cartridges. It can be configured with one or two DLT7000 tape drives. The latter offers additional enhanced functions such as faster transfer of data, simultaneous backup, concurrent read-write operations, and fault tolerance.

The Model 105 is a stand-alone desktop unit and the Model 106 can be mounted in an industry-standard EIA-310-D 19-inch rack, such as the IBM 9306 Netfinity(R) Rack Enclosure. It utilizes DLT-format tape cartridges that provide 35GB native capacity and up to 70GB with 2:1 hardware controlled data compression, giving the 3447 a typical storage capacity of up to 1.05TB with compression. The 3447 has a native data rate of 5MB per second and up to 10MB per second with compression. This is equivalent to 36GB per hour with compression on a one-drive model and up to 72GB per hour with compression on a split-host, two-drive model. A bar code reader, allowing for positive tape cartridge identification and inventory, and an operator display are included.

The IBM 3447 Models 105 and 106 can be used for save/restore, program distribution, migration, data interchange, automatic migration of data between disk storage and tape, and mass storage for data archive. Full interchange of data is supported with the IBM 35/70GB Internal Digital Linear Tape Drive (00K7900) using DLT-format cartridges, used in the PC Server 704. In addition to reading and writing on DLT-format tape cartridges, the 3447 provides an enhanced functional alternative to 1/4-inch, 4-mm, or 8-mm tape drives. Storage and tape management for the 3447 is provided by software such as IBM ADSTAR(R) Distributed Storage Manager (ADSM) and other industry-leading compatible software offerings.

NOTE: Although the tape drive in the 3447 provides the capability for high tape performance, other components of the system may limit the actual performance achieved. Also, although the compression technology used in the tape drive can typically double the amount of data stored on the media, the actual degree of compression achieved is highly sensitive to the characteristics of the data being compressed.

The 3447 Digital Linear Tape Library features:

• Up to 525GB/1050GB data storage capacity
• Bar code reader
• External stand-alone desktop or rack-mountable models
• State-of-the-art cartridge handler designed for reliability
