This software is a powerful and comprehensive tool for improving the layout and performance of Novell NetWare file systems. Download an evaluation release supporting NetWare volumes up to 1000 MB or purchase a copy with no volume size restrictions.

Read about some good reasons to defragment your NetWare volumes here.

Novell's comments on defragmenting NetWare volumes:

  • TID 2912014
  • TID 10027705.
  • http://www.novell.com/coolsolutions/smallbiz/ask_the_experts.html#3002514
  • GroupWise, like any other electronic mail system, moves messages and attachments to various directory structures, copying and deleting from layer to layer. Over time, massive deletions can lead to file fragmentation on the hard disk. If you notice a decrease in performance, it may prove helpful to run a hard disk optimization utility. However, because network drives are large and the file server has to be taken down in order to run such a utility, it is inconvenient to run the utility on a server. Full document.

  • Complete volume optimization.
  • Defragments all NetWare volume data areas.
  • Redistribute data across a volume after a new segment is added.
  • Supports Partition Mirroring and Multi-Segment volumes.
  • Supports any size NetWare volume.
  • Very fast and reliable.
  • Supports execution from scripts.
  • Supports Traditional and NSS volumes.
  • NetWare 3.x, 4.x and 5.x.

A common belief is that Novell NetWare volumes do not become fragmented and that defragmentation is not important. This is simply not true. There are many good reasons to defragment volumes. For example: after adding a new volume segment to a volume, the new segment contains no user data. By defragmenting the volume, data is redistributed evenly across all volume segments.  System administrators can now measure the performance affects that fragmentation causes.

Novell has recognized that defragmenting the Directory Tables has an effect upon volume performance. See Novell TID 10027705. Starting with NetWare 5 SP4, Novell has improved volume mount time. Part of this improvement is due to "The directory table layout for new volumes was optimized to give better locality on disk. This improves the speed that the data can be read off the disk" 

How often have you seen the following:

  1. High server utilization -> Defragment the Directory Tables.
  2. Volume mount time increases. Read more here.
  3. Vrepair run time increases. Read more here.
  4. Open, closing and modifying files takes longer.
  5. Backup performance decreases.
  6. Backup tapes store less and less data per tape.
  7. Increasing delay times to load large applications like Microsoft Office.

These are just a few of the problems solved by defragmenting and redistributing data on Netware volumes.

Details:

  • Defragments Primary and Secondary Directory Tables.
  • Defragments Primary and Secondary Extended Directory Tables.
  • Defragments Block Suballocation Tables.
  • Defragments File Data.
  • Defragments Extended File Data.
  • Support for moving files which have not been accessed for a while towards the end of the volume.
  • Support for moving deleted files which have not yet been purged towards the end of the volume.
  • Support for changing the order of Directory Table entries.
  • Support for changing the order of Block Suballocation Table entries.
