    TeamQuest D-Fragger

    TeamQuest D-Fragger helps you compact mass storage by defragmenting files, consolidating free space for future allocation, and minimizing DAD entries. It decreases Exec time and streamlines I/Os. D-Fragger also reports disk fragmentation on allocated and unallocated space.

    TeamQuest D-Fragger can help you:

    • improve job turnaround times
    • free up administrator and operator time
    • increase the amount of available mass storage without purchasing disk drives

    This graph reflects the number of I/O requests for two executions of the same user database application. In each case, the user application generated around 130,000 user I/Os. The first instance of the database application caused the Exec to perform over 1.7 million I/O requests to service the database utility, many of which were a direct result of the Exec following links to the fragmented portions of the database files. In comparison, the second instance of the application, run after mass storage defragmentation with TeamQuest D-Fragger, caused only 23,892 Exec I/Os. The difference is attributable to the dramatic decrease in I/O activity required with defragmented files.
