Defrag strategies for Windows 7/Vista that maximize OS benefits, lower network operating costs and boost system performance are easily within your reach.
Tests1 have been run that identify 21 vital areas where you can cut operating costs and increase system performance across your network with windows 7 and Diskeeper. This article is condensed from a newly released white paper. (see page 11 for the download address) 1. GO wITH THe leaDeR. 803 of the Fortune 1000 global companies have implemented Diskeeper and consider it indispensable. Diskeeper has been tested and proven in mission critical environments and continually meets constantly evolving challenges of network performance with innovation. The built-in defragmenter in Windows 7 is essentially the same as the one in Vista.
3. GeT THe JOB DOne wITH zeRO IMpaCT On aCTIVe sysTeM ResOuRCes. If a defragmenter competes with active system resources, requires downtime or must be scheduled off peak production times, it will cost a company additional time and money to run. Diskeeper 2009 is the only defragmenter with InvisiTasking® technology. It provides robust, real-time defrag using only idle system resources allowing complete defrag even during peak traffic times.
[fig 3.0: InvisiTasking graph depicting invisible operations]
2. COnsIsTenTly supeRIOR peRfORManCe ResulTs. Diskeeper consistently achieves superior results due to proprietary technologies.
[fig 2.1: Tests show Diskeeper installed on Windows 7 provides greater system performance.] 1
4. BeyOnD DefRaG: GeT THe DaTa yOu Rely upOn fasTeR. Only Diskeeper ® software has I-FAAST® Intelligent File Access Acceleration Sequencing Technology that strategically places the most relied upon files to increase their access speed. While a defragmented file will typically outperform a fragmented file that is optimally placed or sequenced on a disk, Diskeeper gives you both – boosting speed up to 80% more, with 10-20% being the average. Remember that without I-FAAST, a defragmenter can move key files to physically slower regions of the disk, slowing access.
The industry standard desktop benchmarking program, Futuremark Corporation’s PCMark Vantage, was used to measure system performance before, during and after defragmentation with the respective programs.

[fig 4.0: Disk benchmarking program depicting drop at “higher” clusters (65MB/s to 35MB/s]
5. Consolidating free space for optimum filewrite performance. Free space fragmentation is often overlooked, but is just as significant as file fragmentation. Diskeeper includes advanced solutions to consolidate space into a small handful of very large segments to improve future file-write performance.
8. Keeping the MFT from fragmenting. While Windows maintains a reserved zone for expansion of the Master File Table (MFT), as the MFT grows, the size of the reserved zone adjusts dynamically and may move around the volume. While this design reduces fragmentation of the MFT, it does not prevent it. The Diskeeper Frag Shield® technology invisibly provides added protection to gaps left behind, proactively eliminating the need to defrag the MFT. 9. Directory consolidation: Improving data transfer rates. As directories must be navigated when accessing files for particular tasks, consolidation of directories can typically improve data transfer rates. File-based backup solutions are one such example.
[fig 5.0: Comparison of free space consolidation on Built-In Defrag.]
6. Critical technology: Solving fragmentation on metadata and system files. Fragmentation of critical system files can unstabilize an entire operating system. Defragmentation of many system files can be done only when the computer system is offline. But built-in defragmenters offer only online defragmentation modes and cannot defrag important metadata files, the paging file and the hibernation file.
Diskeeper offers a proprietary offline defrag which is specifically designed to defragment these vital system files.
7. Immediate productivity: Increasing boot-up speed. Diskeeper’s ability to defrag more thoroughly and address system files results in faster “cold” system boots.
[Figure 9.0: Directory consolidation improves backup performance.]
10. Eliminating the “full disk” defrag barrier. Built-in defragmenters normally need 15% free space to run a full defrag, though can be forced to run “partial” defragmentation if less space exists. However, the built-in defragmenter becomes increasingly less effective as available free space becomes sparse. Only Diskeeper is designed to defragment drives in a variety of free-space scenarios. 11. Breaking through the large volume (100GB plus) online defrag barrier. The Diskeeper defragmentation engines are built specifically for enterpriseclass servers and that same technology is ported into the desktop versions. The Terabyte Volume Engine™ defrag technology is specially designed to defragment volumes over 100GB with greater efficiency, resulting in less resource usage (memory) and faster run times.
[fig 7.0: Windows Vista systems boot faster with Diskeeper.]
NEWSKEEPER • A DISKEEPER PUBLICATION
12. Peak system speed all the time and the “daily grind”. Waiting until fragmentation affects performance results in increased help desk calls preceded by weeks
of reduced productivity. Scheduling tasks exposes gaps that incur risk and complications. Only Diskeeper provides true real-time continuous fragmentation technology, eliminating any fragmentation related performance loss before it occurs.
[fig 12.0: Studies carried out prove fragmentation builds up daily, and at a rapid pace.]
13. Excluding files that should not be moved. Some files should NOT be moved. For example an anti-virus quarantine folder. Or a whole-disk encryption “boot loader”. Diskeeper offers an exclusion list feature to add these types of files so they will not be moved during the defragmentation process. 14. Optimizing the Solid State Drive (SSD). SSDs suffer write-performance degradation due to free space fragmentation. Only Diskeeper offers HyperFast™ solid state drive optimizer specifically designed to detect SSDs and maintain their write performance at peak levels.
with V-locity™: the first-ever virtual platform disk optimizer for Hyper-V™. 16. Complimentary Windows 7 “XP Mode” licensing. Diskeeper provides an additional complimentary license for XP mode on select Windows 7 editions that support this feature. Windows 7 Disk Defragmenter cannot be used to solve fragmentation in that virtual Windows XP environment. 17. Saving space; Volume Shadow Copy Service (VSS) compatibility. Diskeeper includes superior compatibility with the Volume Shadow Copy Service. Test runs comparing the impact to the VSS difference area by Diskeeper and Windows Vista WDD show that the Diskeeper design is more effective at preventing unnecessary VSS snapshot activity. 18. End user access. With Diskeeper 2009, system administrators have the flexibility to allow nonadministrative end-users access to the Diskeeper UI. While this is disabled by default, the numerous Diskeeper management tools provide the ability to adjust this easily. Non-privileged access to the interface can assist with troubleshooting efforts that require end user involvement (such as remote users). 19. A GUI that offers full graphical administration. Unlike either Vista or Windows 7, Diskeeper offers full graphical control over all features and functions of defragmentation as well as comprehensive local system reports.
[fig 14.0: As free space fragmentation increases, write throughput decreases.]
15. Adding intelligence to Virtual Desktop defrag. Only Diskeeper Corporation offers a solution that provides system administrators completely invisible and automatic optimization across virtualization platforms

tHINGS YOU MAY
NOT KNOW ABOUT DISKEEPER.
1. Diskeeper was designed to be utterly bug-free from the beginning. That’s why today as few as five technical support staff can support 35 million installations.
6. When Diskeeper is installed on a server that is just downright flaky and impossible to diagnose, 9 times out of 10, the server settles down and runs fine.
2. Diskeeper version 1.0 was so efficient, it consisted of only 4,000 lines of code (in assembly language!), consuming 16KB of memory. Diskeeper v2009 continues that tradition of efficiency.
7. Computers running Diskeeper last 40%-50% longer than computers without Diskeeper.
3. When Diskeeper was introduced, lack of an automatic way to defragment datacenter storage was the No. 1 complaint of system administrators, by double the votes of the No. 2 complaint. Today, Diskeeper is the only way to resoundingly eliminate that complaint, and is considered indispensable at 804 of the Fortune 1000 companies. 4. Diskeeper has the best ROI of any software anywhere, as fast as 3-6 months. This is unheard of in the computer industry. 5. A computer running Diskeeper is typically 20% faster than the same computer without Diskeeper.
NEWSKEEPER • A DISKEEPER PUBLICATION
8. Computers running Diskeeper consume 12.5% less electricity than the same computers without Diskeeper. 9. Diskeeper is the only computer program in the world that makes Windows computers faster, more reliable, longer-lasting and energy efficient. 10. At 23 years, Diskeeper is one of, if not the longestlived continuously best-selling computer programs of all time.

the future of
There is a lot about today’s technology that tends to level the corporate playing field. Virtualized resources and services can be as easily leveraged over the Internet by a small company as an enterprise corporation. Communication infrastructures are global, scalable and cheap. They allow businesses of all sizes to jump on the bandwidth wagon. Prices don’t always change but technology continually does. Companies of all sizes must innovate or die. Because of this functional equality, achieving a competitive edge comes down to increasing efficiency in every aspect of an operation. In this economic environment, a company’s cost of operations has become as vital as its product value proposition. And this is no longer just a C-level concern. Napoleon said an army marches on its stomach. But in a world where business is composed of data, today’s corporations ride on the back of their IT networks. There are two types of IT network. One is consumed with Help Desk calls, planned and unplanned downtime, extensive hands-on administration, time-intensive tasks (such as data backup) and the continual need for hardware upgrades. This network is largely an overhead expense. The other network is composed of fast, reliable and long-lived systems that require little to no management. System managers are able to make progress on proactive initiatives without being constantly interrupted with break-fix emergencies. This network is an investment with good bottom line return. And it is within this second IT network that the future of competition lies. Its efficiency allows a company the ability to more fully exploit the potentials of virtualization, new server platforms and applications. It gives a company the nimble feet necessary to seize strategic opportunities. It provides the escape velocity needed to get from internal bureaucracy to “first to market.”
napoleon said an army marches on its stomach. But in a world where business is composed of data, today’s corporations ride on the backs of their iT networks. Understand this and you understand the Diskeeper Corporation mission. Our performance technologies restore and maintain performance at such a core level they return competitive efficiencies of a value far beyond their licensing costs. An interesting parallel exists in the world of Formula One racing. For decades Ferrari and Mercedes dominated these high performance races. But with the recent development of a kinetic energy recovery system (KERS) — adding as much as a 50HP bursts of speed — the field was cracked wide open. The competitive advantages are so significant that this technology will be mandatory in 2010. IT networks with Diskeeper performance technology on every Windows system have innovated efficiency far beyond the norm and returned a staggering amount of bottlenecked energy to the system. More importantly, they enable their companies to take the first-strike initiative on what the future will bring.

TECH a r t i c l e
Answers. An interview with George Dzieciol, Diskeeper Corporation Senior Technical Manager.
Question: What actually is InvisiTasking® technology? GEorge: It is a brand new technology that allows a background process to determine when system resources are idle and perform a task without affecting any other processes on the system. There is no other technology like this.
What we came up with was a way to cause the system to allocate its various resources (CPU, memory, disk and network) separately to the processes that need each one. This allows overlapping use of separate resources, not just reducing system overhead, but eliminating it altogether! Interestingly, because of this, systems actually run faster when InvisiTasking is active than when it is paused.
Question: What makes InvisiTasking unique?
Question: Can InvisiTasking be used in any software application?
GEorge: Previous technology required that you lower priority of background processes — but that never achieved zero system resource conflicts. It would compete with other low priority processes.
GEorge: InvisiTasking can be used for any process that is best run in the background. The SDK integration process is simple and straightforward. It requires signing a licensing agreement.
InvisiTasking, on the other hand, is a true zero conflict technology that allows the process to run robustly and get its job done fast. It’s a first in anyone’s book and offers a level of performance gain unavailable anywhere else. Question: What were the challenges involved in creating InvisiTasking? GEorge: Well, first off, to find a way to determine when the system is in a truly idle state. Since the 1960’s, the scheduler in the operating system has been considered sacred and untouchable. In view of the dramatic shift in the balance of performance (CPU vs. memory vs. disk vs. network) over the past 40 years, we decided to question this.

diskeeper cuts nightly backup time in half! THE COMPANY: Altercare of Ohio, Inc. is an advanced medical rehabilitation specialist company. With a staff of 2500, Alercare is necessarily computer intensive, providing a range of services that includes nursing home care, rehabilitation, pharmacy, billing and medical supplies. This multi-faceted healthcare corporation runs a Windows 2003 64 bit server with a 3 TB RAID5 array and Backup Exec™ to do disk-to-disk-to-tape of all servers every night including a new ERP system. There is also a virtual server on this machine. This busy server hosts target directories for SQL® maintenance plans which copy backups of databases and transaction logs.
“Diskeeper is the only thing keeping our multi-terabyte disk array able to perform as a repository for all the Backup Exec and SQL backup jobs. We have records in the Backup Exec logs showing backup performance degradation over time, and the later improved results after installing Diskeeper EnterpriseServer,” he added. THE RESULTS: Backup Time Examples from our Backup Exec logs before and after: Server A 232GB Before 8:41 elapsed time After 1:42 elapsed time Server B 100GB Before 5:58 elapsed time After 3:53 elapsed time Server C 30GB Before 6:30 elapsed time After 1:46 elapsed time
THE PROBLEM: As more servers were added onto the backup system, the disk-to-disk storage requirements grew. Overall speed slowed noticeably and nightly backup time took much longer. In fact, nightly backup continued throughout the day! Some servers were taking 3 times longer to backup than before. The disk-to-disk performance problem was affecting the disk-to-tape jobs as well. Eventually they were not even backing up current data, only backlogged data from days before. Ideally, they wanted the backup window to be as small as possible and still catch everything. It was not only a LAN issue. The servers were all connected to new GB Ethernet switches. THE SOLUTION: In an effort to handle this, Bill Louth, Senior Administrator for Altercare, installed Diskeeper. According to him, “If we hadn’t implemented Diskeeper EnterpriseServer when we did, our backup jobs would not have been able to complete within 24 hours. Even if they did, what do you do if you need to restore data? You have to wait many hours until the current backup is finished or start cancelling jobs. If I need to restore data, I don’t want to tell the users we’ll have to wait until afternoon to get it,” he said.
NEWSKEEPER • A DISKEEPER PUBLICATION
Server D 73GB Before 7:33 elapsed time After 2:56 elapsed time
“Before Diskeeper, the fragmentation got out of control. Every day Diskeeper moves about 500-800GB of new data,” said Louth. “We have a 3TB array with the EnterpriseServer installed. Without Diskeeper running there was no way to defrag the volume and those backups were taking at least 2-3 times longer. Here are the more serious results: Our nightly Backup Exec 12-hour window has been reduced by 6+ hours.” Then Louth told us more about the return on investment: “The ROI is that our backup jobs would never finish without Diskeeper. I also appreciate Diskeeper’s excellent and courteous technical support. It’s among the best in the industry.”

20. CenTRalIzeD peRfORManCe ManaGeMenT RepORTs. The built-in defragmenter lacks the comprehensiveness of Diskeeper’s reports. What it is capable of is only single system reports — no aggregated central reporting. Although Diskeeper is designed to require zero management, the Diskeeper product family includes enterprise-class central management pieces that offer a window on network performance via full centralized reports and a critical events alerting system
here’s what industrY leaders are saYing about diskeeper.
“ After independent testing, we found that Diskeeper´s automatic defragmenter not only exploits Windows Server 2008 Hyper-V capabilities but also is designed to meet mission-critical expectations in a virtualized environment.” — Eric Jewett, Product Manager for Windows Server Marketing, Microsoft Corporation
“Our customers are asking for us to help standardize both their virtualized and non-virtualized environments, and to have consistent tools to manage systems and applications. Disk fragmentation can be worse in virtualized environments because physical drives serve multiple OSes and applications. Partners such as Diskeeper are offering a familiar approach to optimizing I/O performance, and are broadening the portfolio of products that customers need as they deploy Microsoft virtualization solutions in the enterprise.”
