Storage Capacity
Library Overview
1-17
Calculating Physical Capacity
Use the table below to calculate the physical capacity of a library configuration. For
each module in the library, start with the standard slot count. Then, either add or
subtract slots based on the module’s position and add-on options. Finally, add the slot
counts of each module together to get the total capacity of the library.
Calculation Example 1: Base, DEM, CEMs, PEMs
The example library has a Base module, a DEM, two CEMs (one on each side of
centerline), and two PEMs (one on each end of the library).
Base module
Contains an op panel and three drive arrays. There are modules to the right and left.
320 (standard) + 0 (op panel) + 13 (right module) + 88 (left module) –
66 (2nd drive array) – 72 (3rd drive array) = 283
DEM
Contains a window array, a CAP, and four drive arrays. There is a module to the left.
410 (standard) + 88 (left module) + 23 (window array) – 77 (CAP)
– 66 (2nd drive array) – 72 (3rd drive array) – 78 (4th drive array) = 228
Left CEM
The module is installed left of centerline. There is a module to the left.
516 (standard) + 104 (left module) = 620
Right CEM
Contains a CAP. The module is installed right of centerline with a module to the right.
620 (standard) – 78 (CAP) = 542
PEMs
There are two PEMs, one on each end of the library. The left PEM contains a CAP.
313 (standard right PEM) + 308 (standard left PEM) - 78 (CAP) = 542
Library Total
283 (Base) + 228 (DEM) + 620 (left CEM) + 542 (right CEM) + 542 (PEMs) = 2,215

For additional drive arrays, the first number listed is the change in capacity when there is no module to
the left, and the second number is the change in capacity when there is a module to the left.
