- 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.
