Diskeeper 10 User's Manual

Preface
ix
With Diskeeper, all the volumes in a Windows operating system can be kept defragmented indefinitely.
Diskeeper cleans them up and keeps them that way. This includes volumes with compressed, encrypted and
sparse files on NTFS volumes.
Running either invisibly as a background job or as a manual defragmenter, Diskeeper carefully rearranges files
and free space on a disk volume so they consist of as few pieces as possible. Because Diskeeper runs online,
there is no need to lock users off a disk while it is being defragmented.
Diskeeper is the complete “Set It and Forget It”® solution to the loss in system performance caused by disk
fragmentation!
What’s New in Diskeeper 10
Whether you’ve used Diskeeper before or not, you may already be familiar with some of its features, but
version 10 represents a milestone in the progression of Diskeeper development. New users will find Diskeeper
to be easy to use, yet comprehensive in its capabilities. Experienced Diskeeper users will recognize familiar
features, presented in a new, more streamlined way. This list gives a summary of what’s new in this version.
• Breakthrough I-FAAST Technology
Intelligent File Access Acceleration Sequencing Technology (I-FAAST) improves file access and creation
by up to 80% (average 10%-20%). This is the first industry implementation of “Disk Performance
Calibration”, the modern evolution of the outdated and inconclusive disk optimization strategies of the
past.
When I-FAAST is enabled, Diskeeper runs specially-engineered benchmarks on your disk volumes to
learn their performance characteristics. Diskeeper then transparently monitors volumes for file access
frequency on an ongoing basis to determine which files are requested most often. Special analysis
techniques prevent Diskeeper from being “fooled” by files that have been recently accessed.
Using newly-developed technology, Diskeeper sequences the files to take best advantage of both the
logical characteristics and physical characteristics of the volume. The sequencing process is integrated with
background defragmentation, so it's virtually transparent to you.
I-FAAST intelligence allows Diskeeper to adapt to changing situations—so if the demands on a given
system change, Diskeeper automatically adjusts its behavior accordingly.
This feature is included in Diskeeper Server Enterprise, Diskeeper Server Standard and Diskeeper
Professional Premier editions.
• I/O Smart Enhancements
I/O Smart has been enhanced to completely eliminate performance slows related to disk I/Os incurred by
defragmentation.
I/O Smart technology actively “listens” for I/O requests. During a Diskeeper defragmentation job, if
another application or process needs access to the hard drive, Diskeeper intelligently pauses
defragmentation until the other program I/O requests are fulfilled. Once that happens, Diskeeper gets the
go-ahead to resume defragmentation until another request comes along. Combined with its high-speed
engine, Diskeeper can easily defragment using the “spaces” between I/O requests, even on busy servers.
This feature is included in all Diskeeper Editions.
• Core Defragmentation Engine Enhancements
Improvements to innovative Diskeeper technology provide enhanced defragmentation in low free space
conditions (even for very large files) and unsurpassed free space consolidation. Further advancements to
“comprehensive” defragmentation will consolidate a volume’s free space into 1 or a small handful of
chunks.
