An ounce of prevention…
Why there are no Diskeeper ads at half-time In an era crowded with whistles and bells and the kind of embellished niceties you’re supposed to be lost without, it’s good to remember one thing: all enduring technology is based on hard need. We invented automatic defragmentation nearly 25 years ago as a response to the overwhelming need for an online defragmenter that eliminated having to take an Open VMS server offline to defragment the disk. With the advent of the NTFS file system, we met the need for faster systems requiring less IT management with a completely set-it-andforget-it automatic defragmenter for Windows®. Over the years we’ve been the leading pioneers in the field, taking fragmentation maintenance to its highest levels with fast, reliable defragmentation that worked on even huge mission-critical servers. To this day, no other solution comes close. However, our purpose is not “to defragment” but rather to fulfill the IT manager’s need for increased speed and efficiency across an entire system (and by extension, network). And so we looked deeply into the many simultaneous interactions that occur at the system core. As a result, for years now we’ve been delivering key innovations that go well beyond defragmentation, providing performance benefits otherwise unavailable – even some previously considered “impossible.” We developed a new background processing technology that operates with zero active resource conflicts. We have a half dozen more innovations all under the Diskeeper hood and another half dozen currently in development. Our latest breakthrough, IntelliWrite, is a good example of our core level approach. With one stroke it takes the subject of fragmentation from a maintenance issue to a cure. (See our feature article for details). Today’s technology demands relevance, solves real needs, saves money and improves working conditions. That’s why there are no Diskeeper Corporation ads at the “Big Game” half-time. We spend our money on R & D, creating products that make a difference. Peter Mead, Editor email@example.com
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. Our office systems are a part of the Navy/Marine Corps Intranet and all of these systems have Diskeeper running on them as well. I am a big fan of Diskeeper because I am all too aware of the problems that fragmentation can cause on a system. — Mike Mountain, U.S. Navy
Diskeeper makes a huge difference in our system reliability. On average, we would see about 70% fragmentation. I tried other tools but they locked up our database engine, resulting in some unhappy customers. Manual defrag would take hours, and if I was lucky I could get the fragmentation down to maybe mid-20%. Then the following day, after about four hours of system use, the fragmentation would be up to 40% again. With Diskeeper, we are able to take a hands-off approach to defrag and, without taking any of my time, it keeps us in single-digit numbers. — Louis Perez, system administrator, F.W. Davison & Company
From my personal experience, I don’t ever realize Diskeeper is running and our PCs stay defragmented. We never have disk performance issues here — and that’s the point. If Diskeeper is doing its job, nobody should even know it’s running; disk performance should not be an issue, and both of these are true. Now, if somebody could make our anti-virus software more invisible….” — Kerry Farney, ArcelorMittal #28 on Global Fortune 500 list

active fragmentation prevention and the role of
“Things are working very well — as I’ve come to expect from Diskeeper. “So far the IntelliWrite technology has prevented over 70% of fragments on my system. Automatic Defragmentation handled the rest. “Right now I’m using Diskeeper on all of the PCs that I support. Currently, Diskeeper is handling on average about 11,000 fragments daily (74% are handled by IntelliWrite, 26% by the automatic defrag). And the technology is working fine as far as it only uses idle CPU time; I never notice any issues with it running in the background.”

lthough Diskeeper 2010 with IntelliWrite™ technology has revolutionized system performance with the first-ever active fragmentation prevention, its true power comes from a major shift in how system performance operations should be viewed. Preventing fragmentation is one corner of a powerful triangle that includes file defragmentation and free space consolidation. This triangle not only ensures maximum speed and efficiency, it also has a positive impact on all system throughput. But to harness this power, precise and instantaneous estimations of what the computer is doing with free space must be achieved.
manages free space consolidation, IntelliWrite prevents fragmentation by ensuring subsequent writes remain contiguous. IntelliWrite significantly improves upon what the O/S does in this regard. It takes into consideration the O/S type, the application, file type and history, how many apps are running, how busy the CPU is and many more factors. As a result, disk free space is more efficiently allocated to individual files in a manner that prevents a majority of fragmentation. Because the file system stays close to a state of zero fragmentation, reads/writes are faster, require less energy and increase the lifetime of the hard drive.
The Diskeeper 2010 active prevention design works The life of a computer system, particularly well because it is one corner of a performance a server, is a dizzying matrix filled with IntelliWrite triangle, the other two being file defragmentation many processes writing furiously to InvisiTasking and free space consolidation. many files from many programs nearly I-FAAST Advanced simultaneously over and over again.

No two writes, even to consolidation includes additional the same file, are ever written under innovations such as InvisiTasking® zero system the same exact conditions. The state of the disk and the operating system is constantly fluctuating. overhead technology and I-FAAST® intelligent file access acceleration technology. With each point of this triangle Although free space defragmentation can somewhat in play, the operating system can exercise the best reduce the likelihood of fragmentation under ideal choices as to file placement on the disk. As a result, circumstances, it is impossible to predict future space the system runs consistently at the peak performance needs using this method alone. And circumstances are potentials it was designed to achieve. never ideal. Applications don’t write data to files in one big block, they usually write in small pieces and save expansion space. The onslaught of writes from many sources creates file fragmentation and quickly chews up blocks of free space.
Active fragmentation prevention must take into consideration numerous factors present at the time data is being written, while also ensuring that free space is efficiently consolidated. IntelliWrite uses an adaptive, proprietary algorithm that monitors applications’ behavior relative to their data files. While Diskeeper 2010 invisibly

Improving server response time at a global corporation The company: AO Smith Electrical Products Company, #817 on the Fortune 1,000, has over 3,000 employees and a globally distributed computer environment including over 120 servers across the United States, Europe, Mexico and China. AO Smith is a Microsoft shop with some Linux and Oracle, and primarily uses Dell PowerPath, EMC SAN, Clariion and Equalogic iSCSI. They have thousands of Dells in their desktop/laptop environment. The challenge:
The administrative demands of a global network ruled out the builtin defragmenter. It just wasn’t an effective solution for application, database or file server defragmentation. It required scheduling in large windows, off high production times. AO Smith is a threeshift company with heavy traffic running 24/7. They’d been getting poor file server response time and file corruption. Backups were slow and caused undue downtime to complete. Help Desk was receiving several hundred calls from users about poor file server and application server performance.
David Henry, Systems Administrator for AO Smith, said, “I first became interested in Diskeeper when I discovered many forums, conferences and colleagues strongly recommending Diskeeper. Initially, we purchased five licenses to pilot. Diskeeper Administrator was able to give us a concise report on performance increases and showed us that rolling out Diskeeper on our network would be cost effective and the right thing to do. We use Diskeeper EnterpriseServer on our SQL platform and it is excellent. Remember that our servers interact with hundreds of very high-end testing and research machines and fast response is vital. System response is a key contributor to why we succeed so well as a company. “Diskeeper Administrator allows me to manage performance across my network. I can run reports and
pull disk metrics — even on machines that don’t have Diskeeper installed — so I know exactly where to deploy Diskeeper. When considering the true time, money and effort involved in network management, I can say that Diskeeper pulls its weight.” The results: “Our backup times have been cut by about 75%,” said David. “The best feature is that Diskeeper removes my worry about whether the disk is being maintained at the highest possible level of performance. We noticed the best increase of performance on our file servers. The EMC SAN is for database servers, VMware and file servers. Diskeeper works smoothly and all servers are now reporting quicker boot times and better response times. Everyone in the company has benefited from the Diskeeper deployment!”

A chat with
diskeeper chief technology ofﬁcer A 29-year technologist and industry expert on disk defragmentation, Mr. Quan has overseen all Diskeeper Corporation product development for Windows since NT v3.5. He recently took a break from a busy schedule to answer four questions I put to him.
from a technology perspective, what role does Diskeeper Corporation play in the corporate world? Our objective is simply to improve the performance, reliability, longevity and energy efficiency of computer systems. I say “simply” but there is actually quite a bit of advanced technology we’ve developed under the hood to pull this off. Although improvement is immediately noticeable on every system, it is the aggregate gain throughout an enterprise network that is really striking. We have over 38 million licenses sold, so I know we’ve made an impact. how does “fragmentation prevention” fit into this? We know that preventing fragmentation on the hard disk drive will improve each of our four target objective. Instead of allowing a system to waste resources writing fragments to disk, we take an active approach and cause files to be written contiguously in the first place. There is a quote from Peter Drucker that sums it up nicely. “In cost control an ounce of prevention is worth a pound of cure.” It’s true. Preventing fragmentation creates significant cost reductions from diverse areas. now that Diskeeper 2010 contains IntelliWrite fragmentation prevention technology, is defragmentation obsolete? No. IntelliWrite prevents a majority of fragmentation from occurring, but it does not completely eliminate it — yet.
The reasons it is so effective — preventing up to 85% of all fragmentation — is because Diskeeper 2010 takes a whole system view, ensuring that sufficient free space is contiguous and intelligently used, much of the fragmentation is eliminated and files are written contiguously. And, of course, there are other optimization features in Diskeeper that help ensure the users are getting the utmost performance from their systems.
What’s next? What I can tell you is that, unlike most software companies, we spend the bulk of our resources on research and development. As a result, we’ve elevated our understanding of system performance to a level that breaks with the customary model of incremental improvements. Diskeeper 2010 represents a theory shift and we will continue to make improvements for the corporate IT site beyond normal expectations. To quote Peter Drucker once more: “The best way to predict the future is to create it.”

MYTH #1: The built-in defragmenter
Myth #2: Fragmentation is not
is good enough.
an issue with SAN/RAID/SSD and virtual platform technology.
The truth: The built-in defragmenter has basic limitations that add to operational expenses. The rate of fragmentation increases as normal business throughput increases. As the built-in defragmenter lacks operational transparency, it canâ€™t keep up with daily fragmentation and must be scheduled off production times. Because fragmentation has built up during work hours, scheduled defrag times are often too short to get the job done. Using the built-in requires administrator time for planning. When many systems are involved, this is a significant man-hour drain. Diskeeper 2010 performance technology goes much further. It prevents up to 85% of all fragmentation before it can happen. Any remaining fragmentation is handled in real time, automatically, with zero system resource conflicts. Computers run at close to zero fragmentation without the need for administrative time.
The truth: No matter how you store data, all file systems fragment and eventually bottleneck I/O throughput and increase the time and energy required to do the same amount of work. New storage technologies abstract disk file systems from the actual underlying hardware and software that make up the storage subsystem. Those same underlying disk systems (software and hardware) have no knowledge of what the file system is doing. No matter how or where you store your data, solving file fragmentation has never been more vital for peak system performance and reliability.

Myth #5: New computers operate at the

peak of their ability.
The truth: This was certainly true with manual defragmenters. They had to run at high priority or risk getting continually bumped. When the built-in defragmenter became schedulable, not much changed. The defrag algorithm was slow and resource-heavy, suitable maybe for an emergency but certainly not for standard system performance maintenance.
The truth: Even on a large-capacity hard drive, just installing an operating system fragments files considerably. Every additional application or utility installed increases the level of fragmentation. Here is a screen of a disk fragmentation analysis on a new hard drive:
Diskeeper 2010 includes InvisiTasking ÂŽ background processing technology that allows defrag operations to run in real time with zero resource conflicts, no matter how heavy the I/O throughput traffic is. Add to this the fact that Diskeeper 2010 also prevents up to 85% of all fragmentation from happening in the first place and you have a machine with far more available system resources than it would have had otherwise.
Myth #4: You can wear out your hard drive if you defragment too often.
Exactly the opposite is true. When you eliminate fragmentation you greatly reduce the number of disk accesses needed to bring up a file or write to it. Even with the I/O required to defragment a file, the total I/O is much less than working with a fragmented file. For example, if you have a file that is fragmented into 50 pieces and you access it twice a day for a week, thatâ€™s a total of 700 disk accesses (50 X 2 X 7). Defragmenting the file may cost 100 disk accesses (50 reads + 50 writes), but thereafter only one disk access will be required to use the file. Thatâ€™s 14 disk accesses over the course of a week (2 X 7), plus 100 for the defrag process = 114 total. 700 accesses for the fragmented file versus 114 for the defragged file is quite a difference. But in a real-world scenario, this difference would be multiplied hundreds of times for a true picture of performance gain. The ability of Diskeeper 2010 to prevent fragmentation in the first place reduces hard drive activity far more than even defragmentation can.
