TeraPack Cases for Tape Media
The Spectra T950 library uses grouped media:
that is, multiple tape cartridges are grouped in
their own container, which is used throughout
the library and beyond. The packs of cartridges
are called TeraPack case (shown in Figure 2-3).
Each TeraPack case holds 10 LTO or SAIT tape
cartridges, or 9 SDLT cartridges. Each cartridge in
the TeraPack case is bar-coded, along with each
TeraPack case itself, so that all cartridges and
TeraPack cases are unique and able to be rapidly
scanned and identified.

The library’s robotic mechanism, the transporter, handles media in two ways: a macro
movement grasps and moves an entire TeraPack case, while a micro movement
manipulates individual tapes—moving cartridges in and out of TeraPack cases, and
into and out of tape drives.

Storage Density
TeraPack cases and RXT media packs take advantage of space within the library that
traditional libraries don’t. Because of this, the library’s storage capacity is enormous.
traditional libraries don’t. Because of this, the library’s storage capacity is enormous.
The T950 library uses space in an innovative fashion, permitting very high density by
using space within the library, rather than accepting the limits of tape storage on the
vertical library walls. This space use is optimized through the use of horizontal shelves
divided into semi-enclosed chambers. Each chamber is designed to accept a bar-coded
TeraPack case.

The patented TeraPack case lets you import multiple tapes (e.g., ten LTO tapes) at a
time per access port. With LTO TeraPack magazines, twenty tapes at a time can be
imported, ten through each TAP. The transporter (that is, the robotics) moves the
entire pack, ten tapes at a time. The RXT media pack matches the footprint of the
TeraPack case and the robotics move the entire RXT media pack, as well.

This unique design requires the use of the bar-coded TeraPack case, only available
from Spectra Logic. The TeraPack case lets you track tapes in the case through the case
bar code; you can also track individual tapes, since each tape is also bar-coded.
