PRODUCT NAME:  Disk File Optimizer                     SPD 55.85.08
               for OpenVMS,Version 2.6

DESCRIPTION

Compaq Disk File Optimizer for OpenVMS is a layered software product
which reduces both file fragmentation and free space fragmentation and
optimizes file placement on disk media. This results in better appli-
cation performance, better backup performance, and more efficient disk
utilization. Disk File Optimizer operates in two modes. In "Defrag PLUS"
mode, RMS is used as a database of scheduling information, and defrag-
mentation jobs can be scheduled using a wide variety of scheduling cri-
teria. In normal "Defrag" mode, defragmentation jobs are run when re-
quested by the user. The user or system manager can specify which of
these two modes should be used when the product is installed.

The key capabilities of Disk File Optimizer for OpenVMS are:

o  Reduces file fragmentation and free space fragmentation for disk
   devices

o  Provides the ability to defragment specific files or an entire disk

o  Gives the user the capability to select or exclude specific files
   based on:

   -  User choice

   -  Severity of fragmentation

   -  Whether the file has placement pointers

   -  Whether the files are indexed

o  Provides event based scheduling of defragmentation jobs

o  Provides a Monitor function which allows File Optimizer processes
   to be monitored while in operation

o  Allows pre- and post-processing commands to effect automation of
   tasks before and after defragmentation jobs are executed

o  Gives the user the ability to classify files as "hot" (frequently
   accessed), or "cold" (infrequently accessed) and to have them placed
   on the disk drive accordingly

o  Provides two modes of operation to tailor to the specific customer
   environment

o  Offers a choice of Digital Command Line (DCL) or Motif[R]-based Graph-
   ical User Interfaces. This is available for both Defrag and Defrag
   PLUS modes.

o  Provides an offline defragmentation utility that allows the user
   to defragment INDEXF.SYS on a disk device that is not mounted. For
   a bound volume set this utility only works on the "ROOT" volume.

   bre Channel protocol, which the disk device understands. DFO V2.6
   has qualified this new feature in OpenVMS 7.3 as used with MDR. Please
   refer to OpenVMS V7.3 for a complete listing of supported disk de-
   vices.
