    TeamQuest RemD-Fragger

    TeamQuest RemD-Fragger defragments removable mass storage, leaving disk files in contiguous blocks. You no longer have to back up all your files on the drive, delete them, then reload them from tape to defragment your removable mass storage.

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

    TeamQuest RemD-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 RemD-Fragger, caused only 23,892 Exec I/ Os. The difference is attributable to the dramatic decrease in I/O activity required with defragmented files.
