Microsoft and Diskeeper Agree on Free Space Defrag

by Helpdesk 17. March 2006 16:47
There has been some confusion in the past regarding free space defragmentation. Some people in the industry believed that after a defragmentation job free space should be consolidated into one pool. Here at Diskeeper Corporation we have long since maintained that this doesn't make sense (see our whitepaper on this very subject). Moving free space into one consolidated pool is a temporary condition that wastes resources and serves no purpose. Instead free space should be grouped in a few contiguous pools. I was happy to see Microsoft has recently validated our longstanding position. Checkout the section on free space fragmentation in the new Microsoft TechNet article, Maintaining Windows 2000 Peak Performance through Defragmentation: "Free Space Fragmentation A partially full disk contains unused space, known as free space. Ideally, this space would be available in a few contiguous portions of the disk." -Microsoft TechNet -Paul

New Microsoft Defragmentation Recommendations

by Michael 15. March 2006 18:10
A new Microsoft TechNet article, Maintaining Windows 2000 Peak Performance through Defragmentation, was recently published. The article provides a very good overview on disk fragmentation. From 2005 to 2006 Microsoft has improved dramatically in their defrag schedule recommendations, switching from the outdated monthly rule of thumb to recommending a weekly schedule. While Microsoft's recent schedule recommendation is a big improvement, it doesn't go far enough. In this article Microsoft makes the observation that, "normal, day-to-day use of your computer will cause fragmentation". Even a desktop in a client-server environment (where the data resides on a file server) can see 1,000+ fragments build up on its local disk drive in a single day. Worse yet these fragmented files are probably among a small set of files you use the most. A daily schedule is really the way to go. A daily defrag schedule keeps your defragmentation jobs short and handles fragmentation as it occurs, ensuring no losses in performance.

Defrag your virtual servers daily!

by Helpdesk 3. March 2006 19:04
Several months ago I blogged on the importance of defragmenting virtual servers. I was very pleased to see a recent article in Redmond Magazine discussing VMware, storage virtualization and defragmentation. The following is a choice quote from the article:
"Defragment the host's disks as often as possible. Members of the VMware community recommend doing so on a daily basis. With VMware's disk files often consuming gigabytes of space for a single file, even a little fragmentation can significantly impact performance."
More and more people are recognizing the need for daily defragmentation in today's storage environment. A daily schedule keeps defrag jobs short and handles fragmentation as it occurs. Have you defragged today? -Paul

Better late than never

by Michael 9. February 2006 19:02
Before I publish my first blog entry (I think I'm officially the last human with a computer to write one) I will quickly introduce myself. My name is Michael; I'm the Product Manager (PM) at Diskeeper Corporation (DKC). I first joined the company back in 2000 as a Systems Engineer, and moved into product management a couple of years ago. As PM, I'm tasked with making our products the best on the market. Doing that means making sure it meets the needs of you, the customer. My blogs will provide technical data (I had a past life as an engineer before going over to the "dark side"; AKA Marketing -just kidding of course). I will also offer insights into this great company, which I'm very proud to be part of, and personal viewpoints on our products and where I see the industry and our company going. As with most blogs, my personal viewpoints aren't necessarily those of my employer, nor do they guarantee a specific course of action. When and where possible I will leak out a few of our R&D projects (at least to the degree that I can still collect a paycheck afterward). I must forewarn our readers that I may often come across as caustic or impertinent. I don't wish to offend anyone, but understand I am passionate about what I do; and when I'm up on my soapbox I usually have the knowledge and info to back it up. I also consider myself a 'junior' philosopher and pop culture commentator so my blogs will frequently contain references to contemporary events. Feel free to comment on my blogs and correct me when I'm wrong - I can take it. All I ask is that your responses present supporting technical data and not hearsay. I will publish constructive and well intentioned comments, questions or corrections. I'm excited to have this opportunity to share my product knowledge and insight, and hope this information helps you. I want to also thank those of you who currently follow this blog and write to us. We do listen and really strive to address your needs. Your Diskeeperblog team will begin to interact with those of you who have been sending in comments. Our apologies on not having done so sooner, we are still quite new to this technology (and the user manual is reeeeeally long). Please use this forum to ask questions or respond to blog entries. If you have product suggestions, you can submit them by email to wishlist@diskeeper.com. We review these emails as part of our new feature development planning. You can also provide feedback directly into our development database from an option in Diskeeper 10's "Action" menu item (select Action and then Diskeeper Feedback from the Diskeeper user interface menu bar). -Michael PS: Given that our legal dept. approves, we are working to create some audience participation games (with prizes like free software, t-shirts, etc...) into the blog.
