Major Performance Improvement after Running Diskeeper on DFS server

by karen 4. May 2011 05:53

“We are now running Diskeeper 2011 EnterpriseServer on our a DFS server which houses all our corporate documents. This server has about 500GB of files and was heavily fragmented prior to installing Diskeeper. 

“Users were experiencing latency issues, login delays (roaming profiles) and sometimes apps would freeze upon saving to that server. After running Diskeeper for a few weeks, there was a major performance improvement. We went from getting several calls a week prior to the Diskeeper install, down to a couple of calls a month. 

“The other server is a backup repository that houses our SQL backups, BackupExec files and other archived info. This server has over 10TB of storage. Since running Diskeeper, the overall performance of the server and backup times improved greatly.”

Diskeeper 2011 - Software So Evolutionary Where Can They Go From Here?

by Colleen Toumayan 26. April 2011 04:34
Diskeeper 2011 was covered on Wugnet.  Howard Sobel stated, “They introduced technology that slowed down and prevented fragmentation in Diskeeper 2010 so I thought it was impossible to improve on the concept of defrag much more. Not so! By increasing the efficiency of their algorithms, they have decreased the wear and tear on your hard disk and your computing performance while it works in the background. Decreasing the overall disk activity also decreases your electrical consumption. This may not be a huge savings on "your" electric bill but consider how much savings this amounts to in datacenters where thousands of hard disks are used. So being GREEN doesn't mean paying a penalty. In fact, the opposite is true for Diskeeper. I would go as far as declaring this the software utility "Product of the Year" if we didn't have 8 more months to go in 2011.” The full article is located here: http://www.wugnet.com/tips/this_week.asp

Faster File Access Using Diskeeper on SAN

by karen 19. April 2011 06:33
When I asked Patrick Blanche, of Hobbs+Black Architects, whether he saw good results from his use of Diskeeper, this is what he said: 

“Good results? … you mean GREAT right!  Allow me to explain,

We are an architectural business and work with many small interrelated files that can get highly fragmented, so for us using Diskeeper Server is a must to maintain our performance. For the past few years Diskeeper has been working full time on all file servers in Michigan, Arizona even Utah, and the result has been significant improvement in the user experience.  Back before Diskeeper, (a time I would rather forget) we suffered from literally days of waiting for Windows built-in defrag to try and cope with our TB size volumes.  Finally Diskeeper came along and we have seen those issues vanish.”

Then we worked up a fine case study about the performance benefits to his company and now they are deploying Diskeeper on all of their servers and workstations company-wide!

Nice article on CTOEdge for Diskeeper 2011

by Colleen Toumayan 18. April 2011 15:39

Michael Vizard, Industry leader and IT Editor wrote an article on Diskeeper 2011 and stated,

"But as more applications begin to share the same IT infrastructure thanks to the advent of virtualization and cloud computing, the more fragmentation becomes an I/O performance optimization issue."

Diskeeper Extremely Shortened and Kept Backup Times Minimized

by Colleen Toumayan 5. April 2011 05:22

Daiwa Odakyu Construction Co., Ltd.  

Problem 

Daiwa Odakyu Construction Co., Ltd did back up of 15 Servers every day using Symantec Backup Exec. But the problem of latency of backup appeared. Initially the system was designed to finish backup within 3 hours at most. But the time grew to 8 hours. They thought additional hardware was needed but had no additional budget. At that time they discovered the cause of latency was fragmentation. First they tried to solve fragments with the built-in defrag. But it solved only 20%. Next a free defrag software was tried. It proceeded to 35% and shortened backup time by more than 1 hour. But 2 days after, the backup time got back to 8 hours. 

Solution 

Mr. Kawata, manager of the Information System Group of Daiwa Odakyu, found Diskeeper® via the internet and downloaded trialware from SOHEI. Diskeeper solved all fragmentation and shortened the backup times down to 1.3 hours. What’s more, IntelliWrite® prevented fragmentation up to 99%! In accordance with their trial, the system without Diskeeper added 1 hour a day to their backup times. 

 

Back up Time(hour) Number of Fragments Number of fragments prevented
Initial design 3.0 - -
Fragmented 8.5 10,000,000以上 -
After defrag by Diskeeper 1.3 250 3,000,0007,200,000
Improvement 85% 99.9975% (断片化防止率99%)

 “I couldn’t estimate such a big influence of fragmentation in the 50% used volume.  The incredible power of Diskeeper is surprising me. The massive fragmentation I gave up trying to solve is now easily defragmented and prevented by Diskeeper, and then this leads to prevent latency of back up completely.  

“The trial without Diskeeper, which resulted in adding 1 hour a day to backup time, scared me so much. With increasing numbers of files, the backup caused massive fragmentation and gets into a dangerous situation. Less than $1,000 investment in Diskeeper is equal to more than $10,000 worth of Servers. I think Diskeeper is vital for file servers and backup servers."  

“I’m thankful to the developers of this surprising software.”
