IBM 3494 Tape Library Dataserver Model
The 3494 Tape
Library Dataserver is
a stand-alone
automated tape
storage subsystem
for ½-inch cartridges
available for
attachment to the
iSeries or AS/400e
server. It provides an
automated tape
solution for
automating tape
operations such as save and restore, migration of data between disk and tape, and other
mass data applications.
It is comprised of a base unit called the Library Control Unit, which is available in two models.
The Model L10 has space for a 3490-C1A, 3490-C2A drive, or a 3490-F1A. The Model L12
has space for two 3590-B1A or 3590-E1A drives. Both models contain the accessor (robotic
arm that accesses the tape cartridges), the Library Manager, and storage cells for the ½-inch
tape cartridges. The storage cell capacity is 240 cartridges. If the #5210 Convenience I/O
Station is installed (allows the operator to add or remove up to 10 cartridges without
interrupting normal operations), the storage cell capacity is reduced to 210 cartridges. If the
30-cartridge Convenience I/O Station, #5230, is installed, the storage cell capacity is reduced
to 160 cartridges. Currently installed 3490-C10, C11, and C22 Tape Subsystems can be field
upgraded to a 3490-C1A or C2A. The 3490-E11 can be field upgraded to a 3590-E1A. The
3490-F11 can be field upgraded to 3490 F1A. The 3590 Model B11 may also be field
upgraded to a Model B1A for attachment in the 3494 Tape Library.
The storage capacity and the number of tape drives can be increased on the 3494 Tape
Library by adding either drive units or storage units. There are two drive unit models
available. The 3494 Model D10 Drive Unit provides space for either a 3490-C1A, 3490-C2A,
or a 3490-F1A Drive Unit and space for up to 300 ½-inch cartridges. The 3494 Model D12
Drive Unit provides space for up to six 3590-B1A drives and 250 ½-inch cartridges. If no tape
drives are installed in the D10 or D12, they can hold up to 400 ½-inch cartridges. The Model
D10 or D12 Drive Units attach to either a Model L10 or Model L12 Library Control Unit. The
3494 Model S10 is the only storage unit model that can contain up to 400 ½-inch cartridges.
The 3494 Model S10 has no support for tape drives.
Previously available storage units and drive units were denoted by feature number #5400 and
#5300 respectively, and then later denoted by model types 3494-S10 and D10. The #5300
