Overview
The IBM TotalStorage(TM) Virtual Tape Server 3494 Models B10, B18, and B20 can now utilize the increased capacity of the recently announced IBM TotalStorage Enterprise Tape Drive 3590 Model H1A.

This increased cartridge capacity can reduce the level of cartridge handling, physical mounts, and number of cartridges required to accommodate your storage requirements, thus lowering the cost per MB of tape storage and
operations. You can upgrade your installed 3590 Model B1A or E1A
Tape Drive to the Model H1A.
