The P2000 is an automated storage and retrieval library that may
consist of up to 8 tape drives and 198 cartridges or 10 tape drives
and either 100 or 192 cartridges.
Tape drive choices include the Quantum DLT 8000 (HVD and
LVD), IBM LTO Ultrium T200 (LVD only), or the Quantum SDLT
(HVD and LVD). Throughput capabilties for these drives are 6
MB/sec, 20 MB/sec, and 16 MB/sec, respectively.

The P2000 Series library comprises three models that support a
wide range of storage and performance requirements (see table 1
table 2
, and table 3). Model numbers are created by combining the
number of drives and the number of storage bins in the library.
Model 8/198 - 8 tape drives and 198 tape cartidge bins

Element Numbering Convention
The library stores tape cartridges in the following locations:
100 storage bins on the back wall
•
1
Up to 92 storage bins on inside of the front door
•
One load port
•
• 8 bins - two stationary LTO load port shelf bin modules (4
bin shelves each) are built into the load port assembly
12 bins - DL T an d SDL T tape c artridges use two remo veable
•
6-cartridge magazines
• If the library is configured with both DLT and LTO tape
drives, stationary LTO load port shelf bin modules are used
Up to 10 tape drives
•
Figure 1
shows the storage bin, load port bin, and tape drive
numbering conventions. These conventions are used by the library
touch screen graphical user interface (touch screen GUI) and the
diagnostic software program.

Features and Benefits
The P2000 library provides the following features and benefits:
High-capacity, high-performance data storage and retrieval
•
• The library may house up to 198 tape cartridges in
configurations with up to 8 tape drives in only 7.25 square
feet of floor space, or...
• The library may house up to 192 tape cartridges in
configurations with 9 or 10 tape drives
Expandable library configurations
•
• Up to five P2000 and/or P3000 libraries can be joined

When using a Pass Through Mechanism on the
right side of the P2000 library, 8 tape drives and up
to 192 tape cartidges may be used. When using a
PTM on the left side, tape cartridge capacity is
reduced to 168 while up to 10 tape drives may be
used. Finally, when PTMs are used on both sides,
tape cartridge capacity is 168 and 8 tape drive s may
be used.
