HP Interface Manager and Command View for Tape Libraries 3.7 User Guide

Drive Performance tab
In the Drive Performance tab, information about drive performance over the last several backups
is shown. There are two bar graphs for each day representing the native transfer rate and the host
transfer rate.
The X-Axis displays the tape's serial number and date. The serial number is a link that launches
the Tape Performance and Utilization Dialog that defaults to the Tape Performance tab. The Y-Axis
displays the transfer rate in MB/s with values ranging from 0 to 400.
Hovering over or clicking a host transfer rate data point on the graph displays a tool tip that shows
the tape serial number, barcode, and the date and time. On the Host transfer rate graph it also
shows the estimated host rate in MB/sec and the compression ratio. On the Native transfer rate
graph it also shows the native transfer rate in MB/sec.
