Which four activities are part of evaluating the tape application workloads supported by an
SL8500?

A.
dedicating rails to separate workloads

B.
grouping tape drives by type function and quantity

C.
managing cartridges for improved performance and archiving

D.
minimizing elevator and pass-thru activities

E.
mapping CAPS and pass-thru ports to partitions

Explanation:
A:Dedicating rails—separating workloads to specific rails
Note:
Assign each workload its own tape drives, data tapes, scratch tapes, and free cells.
Dedicating separate resources to each workload and configuring these resources on as few LSMs
as possible decreases pass thru activity, minimizes the time to mount tapes, and maximizes library
throughput.
B: Grouping tape drives—locating them by function and drive type, with enough drives to support
the workload
Note:Application-specific requirements may separate drive-types.
Example: placing T9840 access-centric tape drives on one rail, and T10000 capacity-centric tape
drives on another.
C:Managing cartridges—moving inactive cartridges to archival LSMs or ejecting them. Maintaining
free cells on each rail so cartridges can “float” there on a dismount.
D:Minimizing elevator and pass-thru port activity—enabling float and using CAPs intelligently.
Note:Do not try to distribute tape drives across all four rails is usually as this can increase passthru activity by the elevator and decrease overall performance of the library.
