A system includes a utilization calculation module, a performance calculation module, an input module and an output module. The input module to receive a user-selection of tape drives and time ranges over which to calculate utilization data and calculate performance data. The utilization module to calculate utilization data of the selected tape drives over the selected time ranges. The performance module to calculate performance data of the selected tape drives over the selected time ranges. The output module to generate single data points representing output of utilization data and performance data of the respective selected tape drives, and to analyze the data points to determine whether to highlight the data points in a first user-definable display region representing higher utilization and performance tape drives relative to data points in a second user-definable display region representing lower utilization and performance tape drives.
