Disk Performance Analyzer for Networks (DPAN) 3.0 is released

by Michael 19. April 2010 07:32

We just updated and released a new version of a popular freeware product for IT Professionals managing Windows networks. The DPAN 3.0 feature set was already included in Diskeeper Administrator 2010 release, but is now available independently (and free).  

Specifically the DPAN 3.0 free app now implements the following new features:

• Support for Windows 7 and Windows 2008 Server R2

• Support for 64-bit operating systems

• Scanning Active Directory security groups

• Improved Performance Reports consistent with Diskeeper 2010 and Diskeeper Administrator 2010

• Help that explains DPAN operation and reports

• UI and usability improvements

IntelliWrite boosts Lotus Domino Performance - Success Story

by Colleen Toumayan 16. April 2010 05:38

Sure I'd love to give a recommendation for Diskeeper.  We are running 2010 now with Diskeeper Administrator and so far I love the improvements. Many of our Lotus Domino servers were so busy that realtime defrag had trouble keeping up, but with the new IntelliWrite technology preventing most of the fragmentation in the first place, we finally have it under control.

 

The systems were running well prior to introducing Diskeeper, but we deployed the software during a project where we virtualized over 80% of our production servers.  Because of the shared storage aspect of our virtual platform I knew that fragmentation would become a serious issue if we didn't deal with it from day one.  The  Lotus Domino servers often had trouble keeping up with the fragmentation rate but most other servers did well with Diskeeper Server 2008.   

The new Diskeeper 2010 has our fragmentation in check across the boards and I couldn't be happier with it.

Do you still need HyperFast if you have TRIM?

by Michael 2. April 2010 11:24

Last month we were a guest on a Microsoft-hosted webinar covering Windows 7, TRIM, and the continuing need for HyperFast. The presentation focused on the most current releases of SSDs from many of the top SSD vendors (Asax, Apacer, Kingston, Micron and OCZ), who were kind enough to provide us with samples. The webinar discussed Windows 7 features to enhance SSDs, covered the benefits of SSD over HDD, and lastly discussed the performance loss due to file fragmentation. That presentation continues to be available for MS partners on the MS partner site.

In the next few months Diskeeper will re-host this presentation, this time with Microsoft as a guest. That webinar will be posted here on the Diskeeper website for everyone to view.

In the meantime, I've included some of the key slides for anyone interested. The tests present aggregate averages from all the SSDs tested, as the purpose was to show their value above HDD, and not as a comparison of one vendor's SSD versus another.  I also realize that there may be questions as to test scenario specifics, etc... Those details were covered in the presentation on Microsoft's site, and will be covered again when Diskeeper hosts the next presentation in a couple of months. So, if you'd like to get into more detail, go to the MS partner portal or stay tuned for the Diskeeper hosted syndication.

The presentation starts by showing that a typical modern SATA SSD (average from above named vendors) clearly outperforms a typical modern SATA HDD.

SSD versus HDD MB/Sec Transfer Rates:

Windows 7 has numerous improvements to accommodate SSDs:

And...

Fragmentation affects SSDs, and yes, even those with TRIM support. Various benchmarking tools and procedures were used to measure the affect of fragmentation on TRIMM'ed SSD performance. (note: TRIM can be initiated in Windows by actions such as emptying the Recycle Bin, but the SSD must also execute the command).

Fragmented SSD versus Optimized SSD test using ATTO Benchmark:

 Fragmented SSD versus Optimized SSD test using HDBench:

 

Fragmented SSD versus Optimized SSD test using PCMark05

Fragmented SSD versus Optimized SSD test using File Copy Test:

Using a specialized SSD optimizer such as HyperFast returns performance to like-new conditions:

In summary, if you want a top performing system, go get Windows 7 and one of those SSDs named above. Then add HyperFast to keep it that way.
