SSD review

by Michael 28. February 2010 12:44

In anticipation of an upcoming presentation (March 10) from Microsoft promoting SSDs, and best practices for optimizing SSDs, is a HyperFast review by V3 (from last year). They tested HyperFast to see what benefit it would provide. Read it here

Defrag SAN, Defrag VMware, Defrag Hyper-V? You should read this...

by Michael 26. February 2010 12:04

If you're looking to defragment SANs (Storage Area Networks) or VMs (virtual machines), you're on the right track. But, there are things you need to be aware of. Defragmenting SAN attached storage and VMs can require planning, implementation, and configuration that is generally unnecessary with direct attached storage (DAS). 

For example, what do you do if you use Thin Provisioning? What about Linked Clones? Does defrag still help if your multipathing? 

The paper sets out to address many considerations and technologies in modern storage infrastructures, and offers "best practices" guidance based on our decades of experience working with many of the largest companies in the world to help them maximize their system's performance and reliability.

It makes for fascinating reading on a Saturday night. Just get the fireplace firing, grab some milk and cookies, get a warm blanket and curl up in bed (or on the couch) and enjoy! ;-)


Defrag for Faster VMware Performance

by Michael 25. February 2010 10:41

The chart below present results from testing our engineers did in conjuction with engineers at a longtime Diskeeper customer, Solvay Pharmaceuticals (now Abbott), last summer. The tests, done on VMware ESX 3.5 with direct attached storage (DAS), were specifically "proof of concept" that Windows Guest VMs need to be defragmented. A tool we frequently recommend called ReadFile was used to gauge speed of file access. Symantec AV was also run and timed.

“My first impression of Diskeeper 2010, AWESOME!  The ability to proactively prevent fragmentation BEFORE it happens is the Holy Grail of disk I/O management.” - Bruce McMillan, Solvay



Diskeeper is helping the "largest internal computer network in the world" run optimally

by Michael 24. February 2010 06:17

With close to 400,000 systems, the Naval Marine Corp Intranet (NMCI), managed by EDS/HP, is "the largest internal computer network in the world" and has been using Diskeeper on their systems for close to a decade now: 

"We run Diskeeper on our two production web servers and the development server that we are using to host a web-based warfare systems interface management tool. The name of the application is Warfare Interface Systems Engineering (WISE). 

I am a big fan of Diskeeper because I am all too aware of the problems that  fragmentation can cause on a system. I use it at home as well. I specifically like the feature that keeps your drives defragmented automatically via a background process that does not rely on manual defragmentation of the drives. Because I know that if you leave that up to a user or even some administrators to do, it will never get done and people will be wondering why their system performance is starting to degrade.  

Our office systems are a part of the Navy/Marine Corps Intranet and all of these systems have Diskeeper running on them as well [almost 400,000]. I know all too well this group of users in our command. I used to work IT support and they would never defrag their systems. I do some PC work on the side with home users and I see the same thing there."

eWeek tests Diskeeper 2010

by Michael 15. February 2010 07:07

"Not only does Diskeeper's software attempt to prevent fragmentation from ever occurring, but it cuts power consumption and unnecessary I/O operations."


- Jason Brooks, eWeek

eWeek ran some tests to see if IntelliWrite really lived up to the promise and, no surprise to us, it clearly did. Their tests, done with Windows XP guests running on VMware vShpere 4, found IntelliWrite prevented 87% of fragmentation. Invisitasking quickly cleaned up the few pieces that slipped through.
