Faster Backups/Archiving/Dedupe/DR success with Diskeeper and V-locity

by Colleen Toumayan 27. January 2011 03:29

"Spokane Regional Health District uses CommVault Simpana backup/archiving/disaster recovery software installed on a dedicated server with 37TB of SAS attached storage.

                                                                                       

We perform daily full and incremental backups of all our servers. The data backup is disk-to-disk-to-tape and is deduplicated as it is saved on the SAS storage. The deduplication process can create a very large number of file fragments, sometimes over 1,540,000 fragments on a 2TB disk array. With Diskeeper EnterpriseServer automatic defrag running the response time of the arrays is approaching 0.02 second delay due to fragmentation. This has reduced our backup time by approximately 25 percent for any D2D2T job. 

SRHD also uses Microsoft Hyper-V and currently has 31 virtualized servers running on an Intel Modular Server. There are 72TB of storage available to the Modular Server via SAS connections featuring dual path IO. All of the data on the SAS arrays is maintained in RAID 60 logical disk drives. Since setting up V-locity, which has built-in support for VHD (virtual hard disks), with automatic defragmentation, our VHDs very seldom show any fragmentation. 

                                                         

The solutions also have the intelligence to monitor disk IO and the defragmentation will pause to prevent IO latency affecting performance. They are set and forget applications which perform a very well without impact on our server response times."

Diskeeper 2011 outmuscles fragmentation

by Colleen Toumayan 12. January 2011 09:29

Bruce Pechman the "Muscleman of Technology" stopped by out booth at a CES media event. We talked a bit about the upcoming new Diskeeper release and he was kind enough to express his enthusiasm to us in writing so we could publish it:

As a TV Technology Journalist, high-end computer enthusiast, hard core gamer, and a person who is consistently buying the fastest computer money can buy, I need my computers to have super fast performance without any bottle necks every minute of every day.

From expensive SSD’s, to traditional rotational Hard Disk Drives—in every combination you can think of, my computers always run flawlessly and speedily thanks to an awesome software program called Diskeeper!

Right now my primary computer is the “Maingear Shift” with an Intel i980 Extreme Processor overclocked to 4.3 Ghz, it’s almost $6,000 and I can’t tolerate any slowdowns from my dual Western Digital 10,000 RPM VelociRaptors hard drives.

The facts are really quite simple. All types of computers will experience disk fragmentation and it can definitely worsen over time if nothing is done to prevent it. Disk fragmentation is the culprit for many annoying computer symptoms such as slow application performance, long boot times, unexplained system slow downs, crashes, etc. Diskeeper prevents these issues from cropping up.I have been religiously using Diskeeper over the years so my computers can realize the full benefits of system performance and reliability...and I can’t wait to install the new Diskeeper 2011—just set it and “forget about it”!

Whether I’m on deadline, overclocking an Intel Extreme processor, or playing Mafia II with every performance benchmark set to maximum settings, Diskeeper is a must install on every computer I own.

Defragmenting IT Healthcare

by Michael 20. December 2010 05:18

Joe Marion is founder and Principal of Healthcare Integration Strategies, specializing in the integration of imaging technologies with the overall healthcare IT landscape. His blog (at Healthcare Informatics) covers challenges and opportunities specifically relevant to optimizing Healthcare IT initiatives.

Medical images are a significant percentage of the the world's storage requirements, and have been predicted to encompass an even greater percentage of future storage demand. In Joe's recent blog post he posed the question "Is Defragmentation a Boon to Healthcare IT Performance?"

In his post he includes personal observations and insight into performance implications fragmentation can incur on IT as healthcare departments themselves consolidate and standardize application use:

"With departmental solutions, there very likely was less emphasis on system tools such as defragmentation applications.  Now that PACS technology is becoming more intertwined with the rest of IT, there should be greater emphasis on inclusion of these tools.  In addition, server virtualization can mean that previously independent applications are now part of a virtual server farm."

He also makes the astute observation that centralizing computing and storage magnifies bottlenecks, making a solution such as defragmentation increasingly more vital:

"The addition of disk-intensive applications such as speech recognition and imaging could potentially impact the overall performance of these applications.  As data storage requirements within healthcare grow, the problem will potentially get worse.  Think of the consequence of managing multiple 3000-slice CT studies and performing multiple 3D analyses.  As more advanced visualization applications go the client-server route, the performance of a central server doing the 3D processing could be significantly impacted."

Windows IT Pro Study - Defragmentation Benefits

by Michael 19. November 2010 03:14

Windows IT Pro recently undertook a survey of users who have applied Diskeeper across their network. The purpose was to uncover the benefits achieved from this solution.

It covers points such as...

Increased hardware life, and reduction in unnecessary I/O:

Improved system stability and less crashes:

Less drive failures and data loss:

Faster backups and bootups:

 

Their conclusion?

“Low overhead in system resources, significant documented potential improvements in performance and reliability, along with the improved user productivity and better IT resource utilization demonstrate beyond a doubt that Diskeeper software isn’t just a “nice to have” option in your standard system configuration for the effective business IT department. It is a “must have” in order to obtain the best possible performance and ROI on your servers and workstations.”
