1. The HFS 3494 Tape Library

Purchased in 1995 the IBM 3494 Tape Robot Library has grown with demand and now spans 10 frames containing 24 TS1120 tape drives and around 3300 slots for the 3592 tape cartridges. The latter are half-inch tape with an in-the-field capacity of about 1TB per volume - allthough this may change with future generations of tape drive. The library permanently holds one copy of all data sent to the HFS and therefore has an effective capacity of 3PB ( petabytes )
