After installing your Automated Cartridge System you will notice an improvement in your 
site system performance, especially for jobs and programs where tape cartridge handling 
is involved. Without any tuning, the ACS should significantly decrease mount/dismount 
times, shorten batch elapse times, open production windows, and reduce operator 
intervention. By making minor performance adjustments, you may achieve even more 
efficiency from your library. 

The performance of a library is related to the following: 

• overall library activity 

• actions performed by systems programmers, at installation or during library 

operation 

• daily operations controlled by an operator. 

This chapter contains recommendations and highlights performance techniques that can be 
helpful to you in making your library operate more efficiently. 

Overall library activity and the type of activities involved are great influences on the 
performance of the library. In a large data center, the vast volume of jobs running that 
require entering and ejecting of cartridges, mounting, dismounting, tape drive cleaning, 
and pass-thru ports determine the performance of the library. 

Without proper planning and implementation of techniques to control how all of these 
activities affect performance, a library may not operate as intended or preferred. 
Therefore, it is important that you customize techniques and employ standard methods 
developed especially for your data center to optimize the overall performance of your 
library.
