- The IBM 7208-234 is a high-function, high-capacity, external 8mm
tape subsystem used in applications requiring more single tape cartridge
and total storage capacity than is available with the IBM 7208 Model
232 tape subsystem. The 7208-234 provides two 8mm tape drives within
a single enclosure. It is read/write compatible with IBM 7208 Models
002, 012, 222, 232, and AS/400* Advanced Series feature #6390 (7 GB
8mm Cartridge Tape Unit) using the appropriate tape cartridges. The
IBM 7208-234 attaches to the host AS/400 SCSI attachment feature via
SCSI cable. The IBM 7208-234 is intended to complement the design of
the AS/400 Advanced Series and is only available in Raven black color.
The IBM 7208-234 provides: tape mirroring; automatic cascading from
one drive to the other for extended unattended operation; and performance
enhancing features including dual-host channels and off-line, host independent,
functions (tape copy and compare). The IBM 7208-234 also incorporates
a 16-character display for enhanced operational status and diagnostics
and a 2-button panel to control operation of off-line functions. It
attaches to the host AS/400 via SCSI cable. Additionally, an integrated
label printer port is included to generate data cartridge labels when
an optional label printer is connected. The IBM 7208-234 is a dual bus
SCSI device that allows attachment to two separate AS/400 SCSI I/O ports.
Each individual drive in a 7208-234 may act separately, allowing two
individual data streams to be serviced without loss of flexibility.
The IBM 7208-234 emulates an IBM 7208-012, and no new operating system
or application programs are required to use this product. The 7208-234
has a capacity of up to 28 GB (14GB X 2) and a data transfer rate of
up to 1 MB/second per port when using data compression (+). Native capacities
are up to 7 GB of data per cartridge and a data transfer rate of up
to 500 KB/second per port. Is an external stand-alone tape-drive device.
- Attaches via SCSI cable.
- Uses an SCSI interface for attachment to RS/6000 (7208 models 001,
011, and 341), or uses a differential SCSI interface for attachment
to AS/400 (7208 models 002, 012, 222, 232, 234 and 342).

Product Features:
- Dual 7 GB (native) 8mm tape drives
- Dual-host attachment
- Front panel display and operator control switches
- Label printer port
- Raven Black color to complement AS/400 Advanced Series
On-line Modes:
- Cascade
- Mirroring
- Concurrent
Off-line Functions:
- Copy and compare
- Verify
- Erase
On-line Modes
Three operation modes may be selected using the front panel of the IBM
7208-234.
- Cascade Mode - In cascade mode the IBM 7208-234 may use both
cartridges for the same backup or restore job. Capacity reaches up to
28 GB (14GB x 2 with data compression) for any single tape job and does
not require any special system software.
- Mirror Mode - When mirror mode is selected, two identical tape
cartridges are created simultaneously. This facilitates off-site vaulting
and similar disaster recovery requirements. Additionally, single-drive
failures, such as defective media, will not impact completion of tape
operation, thereby raising reliability of backup during a critical window.
- Concurrent Mode - When concurrent mode is selected, each drive
acts like a single IBM 7208-012, but with up to 14 GB capacity (with
data compression), thereby allowing two individual data streams to be
serviced without loss of flexibility.
Off-Line Functions
The IBM 7208-234 can perform off-line tape storage functions not available
with the IBM 7208-012 or 7208-222. These added off-line functions can
be selected and controlled using the front panel of the of the IBM 7208-234.
These functions do not require attaching the 7208-234 to a host computer
system.
- Copy Function - The copy function creates a second copy of
a previously recorded tape cartridge.
- Compare Function - The compare function checks for the exact
agreement between two copies of the same data. The user is notified
of any differences.
- Verify Function - The verify function reads a tape cartridge
searching for tape media errors. This function permits the verification
of the quality of the data on a previously recorded tape cartridge without
using a host computer system.
- Erase Function - The erase function magnetically erases all
the information on a tape cartridge. The erase process allows sensitive
data to be removed from a tape cartridge.
Product Features
- Dual-host attachment (F/C 2503) (For IBM US, No Longer Available
as of June 25, 1999) - Allows connections to two host systems thereby
allowing customers to minimize the quantity of peripherals purchased.
The integrated controller allows each host port to appear as an individual
IBM 7208-234. All enhanced functions (mirroring, cascading, etc.) are
available to both host ports, managed intelligently by the integrated
controller. Alternatively, customers may attach both tape subsystem
ports to separate AS/400 SCSI I/O ports on the same host system and
thereby facilitate two simultaneous tape jobs operating concurrently
to the separate drives, decreasing overall backup time, but without
losing cartridge compatibility with IBM 7208-012 or 222 if desired.
- Front Panel Display and Operator Control Switches - The IBM
7208-234 has a front panel display and operator control switches. The
high-resolution 16 character back lighted LCD display permits the operator
to view the tape drive status during operation. Two operator control
switches allow the selection of operations and configuration modes from
a simple menu format. The status messages during write and read operations
show the amount of data written or read during that operation. This
allows the operator to observe the operation progress. The status messages
also include operator prompts for loading the tape cartridge and for
drive cleaning. Used together, the front panel display and operator
control switches permit the viewing and selection of menu items. This
permits the selection of the on-line modes of operation, and the selection
and control of the off-line functions. The display and operator control
switches also permit the use of diagnostic support operations for service.
- Label Printer Port - An integrated RS-232 port is preconfigured
for label generation when an optional label printer is attached. High-contrast,
high-resolution labels containing Volume IDs, copy identifiers, and
user-defined data fields simplify tape inventory management.

7208-234 has more than double the capacity of a 7208-222, up to 28 GB
of data with data compression(+). The 7208-234 tape subsystem increases
the available capacity compared to the 7208-232 tape subsystem through
the use of higher capacity tape cartridge (14 GB typical with data compression
compared with 10 GB typical with 7208-012 and 7208-232).
