Reducing I/O's in Your Data Centre

Reducing I/O's in Your Data Centre

LONDON, April 13, 2011/PRNewswire/ --

    - Improving Storage Sub-System Performance

    Data Centre efficiency could be well defined as the streamlining of any
task, operation, infrastructure etc, to maximise usefulness and minimise
waste. Streamlining data centres by effectively addressing and handling
performance related issues caused by the inherent problem in any NTFS file
system, is vital to ensure up-time and consistent performance throughout.

    NEW in Diskeeper(R) 2011 - "Efficiency Mode" and "Instant Defrag(TM)
technologies"

    With Intelliwrite(R) fragmentation prevention technology found in
Diskeeper, systems are protected against fragmentation caused by the NTFS
file system. Conclusive tests with Diskeeper proved elimination of 85 percent
or more during the initial file write.

    The files that slip through are immediately handled by the new Instant
Defrag feature. This avoids time-consuming, whole-volume analysis in order to
determine what recently written data needs to be defragmented and saves
valuable system resources which can then be used by other
applications/processes.

    New Efficiency Mode addresses fragmentation solely from a performance
perspective - marginal fragmentation having no impact on performance need not
be addressed. Prioritising for speed and performance on computer systems is a
far more cost effective approach. Efficient Mode offers the greatest net gain
in system I/O resource savings ever available.

    Algorithms in Diskeeper 2011 also track the I/O activity on a system, and
can estimate the overall I/Os saved (due to removing fragmentation) with
time-based data available in the Dashboard and cumulative statistics in the
History section. It is smart enough to detect fragmentation that is a problem
and targets it for priority handling. Since it addresses only problem
fragmentation it eliminates the unnecessary extra effort to get to a state of
zero total fragments - peak performance is rapidly restored.

    The new Efficient Mode is designed to minimize the I/O activity of the
defragmentation process, while restoring and maintaining peak disk/file
performance for users and applications. Reduction in I/Os automatically
correspond to better performance within the storage sub system, again
improving the overall performance.

    New Storage Environments

    Since most fragmentation is prevented in the first place, and only the
necessary fragmentation is handled later, in real world this is also
technically ideal for storage environments using Thin Provisioning or
Copy-on-Write solutions that would require activity (e.g., a snapshot/
replication) for file movement generated via defragmentation.

    Time loss is exponential when larger numbers are involved. The speed in
which systems perform and remain on-line in any IT environment must be
priority number one. Diskeeper 2011 brings to the market the only effective
technology which now prevents and handles fragmentation in real-time.
