Determining If You Need To Perform a Boot-Time Defragmentation

by Mark 5. August 2009 11:20

When installing Diskeeper, many users will schedule a boot-time defragmentation immediately after running the product. Even though a boot-time fragmentation is safe, in many instances, this is not necessary and a boot-time defragmentation will require the computer to be restarted to complete the process.  A user should first determine if performing a boot-time defragmentation is necessary. (A person would not go to the car dealer to get an oil change if the oil in his car was changed yesterday.)

It is recommended to perform a boot-time defragmentation if the paging file or Master File Table (MFT ) becomes highly fragmented.  Information on the fragmentation of the paging file and MFT can be found in the Diskeeper Job Report.

If the number of fragments of the paging file and MFT are 5 or less, there is no need to perform a boot-time defragmentation. Please note that it is recommended to run Diskeeper in automatic mode. When Diskeeper is run in automatic mode, Diskeeper incorporates a technology called Frag Shield which helps keep your MFT and paging files from becoming fragmented in the future .

The Insider Skinny: Hyper-V Takes On VMware

by Derek 30. July 2009 08:34

I'm fresh back from the Microsoft Worldwide Partner Conference. This is the annual pilgrimage of 9,000 partners from around the world who come to find out about the latest Microsoft technologies. Obviously, Windows 7 was a highlight. But what struck me most was the amount of time devoted to virtualization, and especially VMware. Here are a few highlights:      Per Kevin Turner (Microsoft’s COO), VMware has changed their licensing scheme. Besides being very expensive, it’s not an easy upgrade path. So Microsoft will leverage this to their advantage—especially on price point—since one can get Hyper-V for free with Server 2008.  People have said that Hyper-V is too early in as a technology to decide on its being a viable alternative to VMware. Perhaps so. But 24 pts market share were taken from VMware with version 1.0 of Hyper-V alone. And now, Microsoft has Hyper-V R2 coming out with a new Live Migration feature to compete directly with VMware's core V-motion functionality.  Good enough to make one want to switch? I don’t know. But Microsoft has put a lot of thought into this. Check out their migration path: Using Microsoft’s new System Center console, one can run BOTH Hyper-V and VMware together. Microsoft views this as their “big differentiator” since VMware can't do the same.  This means with Hyper-V you will have the ease of having both products under "one pane of glass." So you don’t in fact need to give up your VMware if you wish to try both at once. Clever. 

Microsoft referred to this as "offering significant value at a fraction of the cost" (1/6th to be exact) and they showed the side by side pricing to prove it.  I am not really here to say this is right, wrong, good or bad—we deliver products for both platforms. But it does seem to me that the customer is the one who is coming out on top on this one. So it should be an interesting battle to watch.

Hangin' out with Microsoft

by Michael 24. July 2009 11:18

Last week we were in New Orleans at Microsoft's Worldwide Partner Conference.


Diskeeper Corporation staff met with numerous Microsoft PMs and executives regarding existing and future partnership opportunities. Derek De Vette, who overseas partner relations here at Diskeeper Coporation, met with Becky Lymberis, Senior Marketing Manager, Solutions Marketing. With Small Business Servers (SBS) often tasked to do just about everything under the sun for smaller businesses, they tend to need a great deal of advanced care and maintenance. Becky had this to say about Diskeeper on the Microsoft Facebook site:  

“Diskeeper 2009 defrag products increase the productivity of the workplace and keep business systems always running at their maximum peak performance. Diskeeper is a great application for Small Business Server because it helps prevent crashes, slowdowns and sluggishness, extending the life and enhancing performance of the server—helping small businesses to be more productive. Everyone should check out this solution. It’s one of the most cost effective ways to enhance the performance of your customer’s servers.”

The next evolutionary step for defragmenters is coming.



V-locity is here!

by Michael 16. June 2009 06:00

The new virtual platform disk optimizer for Hyper-V platforms is now available for sale and as trialware.

V-locity with InvisiTasking technology installs on both the Windows Server 2008 OS that is running the virtual host and all Windows virtual machines (guests). Each component optimizes its respective Windows OS and performs defragmentation of files and consolidation of free space. This minimizes unnecessary I/O passed from the OS to the disk subsystem and aligns data on the drives for optimal access.

With the proprietary InvisiTasking, V-locity will automatically and invisibly defragment files and consolidate free space on every Windows system it is installed, eliminating unnecessary and excess I/O to restore system performance and reliability for the entire platform. At the same time, V-locity provides a tool to analyze and compact wasted virtual disk space (dynamic disks).

In accordance with most virtualization software products, pricing for V-locity is "per CPU-core" (similar to the traditional per-socket) rather than per operating system. This provides users a fixed cost for their optimization solutions, and makes licensing much easier and more predictable as they 'grow' those platforms.

Get more info about V-locity here.

Future versions are already in the works, including support for VMware's enterprise solutions.
