Diskeeper made and solidified its reputation with the trade-marked phrase “Set It and Forget It”®, meaning you justscheduled Diskeeper and forgot about it. This was a

fantastic improvement over manual defragmentation. Defrag-mentation with Diskeeper was done on a scheduled basiskeeping systems at peak performance and reliability.Times change though. Disk drives have grown to exponentiallylarge proportions. With the growth of disk drives has come anexplosion in the size and number of files stored on disk drives.With terabyte drives (a trillion bytes) now readily available andsmaller drives selling for very little money, you can store a LOTof stuff—practically anything. And file sizes continue toincrease as well.Documents with embedded graphics, large presentations,scanned images, multi-media files, etc., are now residing onhard drives. The vast quantities of these and their inordinatesize (plus the fact that these media files need to reside con-tiguously on a disk for optimal use) present new challenges forcomputer performance and reliability, making defragmentationmore critical than ever.As disks grow bigger and files grow larger and more numerous,defragmentation is required more and more often to maintaina computer’s peak performance and reliability. This makes itabsolutely vital to handle disk fragmentation as soon as itoccurs. But scheduling a resource-intensive task—such as nec-essary daily or even hourly defragmentation—can be a scaryproposition for IT staff.System tasks such as defragmentation, backups and malwarescans are therefore often scheduled for off-hours, or duringdowntime. This approach is taken to minimize the interferencecaused by maintenance. Waiting for scheduled maintenancetasks, however, introduces negative effects between sched-uled activities, and it can bring about unavoidable negligence inmission-critical servers that cannot be taken off-line.Additionally, the scheduling itself is a maintenance chore whichadds administrative overhead. IT staff need to ensure sched-uling is understood and correctly set for each system. Follow-up is needed: Did the job run, is it complete, and so on?

InvisiTasking—Completely Automatic, Undetectable DefragmentationWhile many software products attempt to run invisibly in thebackground and some strides have been made, complete andutter transparency has never before been achieved—until now.InvisiTasking is a remarkable new technology which enablesDiskeeper 2008 to run invisibly with absolutely no intrusion on sys-tem resources. As CPU and I/O resources are almost never fullyutilized, InvisiTasking’s transparency is achieved by undetectablytapping into these unused system resources. InvisiTasking moni-tors resource consumption on a Windows system (disk, memory,network and CPU usage) and injects Diskeeper processing into theunused portions—and only the unused portions.

Software engineers sometimes attempt to share resources bychoosing lower CPU priorities to run under, and past effortshave been made at throttling disk and network I/O. Windowsallocates CPU resources using a kind of hybrid round-robin/pri-ority based pre-emptive scheduling. One aspect of this schemecan cause low priority processes to unnecessarily preempthigher priority processes, starving them of CPU resources.InvisiTasking utilizes a technique to avoid using a CPU time-slice when higher priority processes need to run.InvisiTasking takes a proactive approach to instantly detectresource usage and network traffic, while carefully managingmemory usage and maintaining complete granular control overits own I/O. This ensures that Diskeeper never pre-emptsusers or services. InvisiTasking is so good that it is all butimpossible to even detect whether Diskeeper 2008 is running.It’s important to note that InvisiTasking is far more advancedthan any low-priority I/O approaches that do “I/O throttling.”First off, InvisiTasking goes beyond I/O to address all systemresource usage. With Low Priority I/O approaches, there canstill be some contention for resources at the disk and it doesnothing to address other system resources. InvisiTaskingchecks to make sure there is no resource contention anywherebefore processing. It applies a pro-active (rather than re-active)approach designed to truly deliver background operation.InvisiTasking is essentially a resource delegation frameworkallowing the OS to operate at a higher efficiency. InvisiTaskingachieves across-the-board compatibility by allowing applicationsand services to operate under an additional layer of resourceallocation. When operating in the InvisiTasking framework, evenI/O intensive processes are able to achieve transparency.

Diskeeper 2008 with InvisiTasking—Truly Automatic and InvisibleDiskeeper 2008 is designed to go to work on-the-fly in real-time—when needed. Since it runs transparently with no intru-sion on system resources, no scheduling is needed by IT staff.Racing to handle performance and reliability, defragmentationwith Diskeeper begins almost immediately. Diskeeper keepssystems running at maximum speed and reliability at all times.The result? Less downtime, less work and trouble for IT staffand boosted user productivity and superior performance. Thatis why maximum benefit to you comes from deployingDiskeeper on every system you manage.You may be skeptical at first that InvisiTasking has virtually noimpact on system overhead. For this reason, you can scheduletimes when Diskeeper is prevented from running. Eventually,we’re sure you’ll be convinced and this type of lock-out sched-uling will be forgotten.The scheduling era is over. Diskeeper 2008 races forward intothe future and the era of truly automatic, invisible defragmen-tation has begun.

Diskeeper Product Manager Michael Materiegives the scoop on the real-time benefits of Diskeeper 2008 with InvisiTasking

What is the difference betweenthe scheduling and “real-time”defrag?To give you a quick answer to the ques-tion, scheduling is, of course, defining atask to run during a set time period suchas 10 p.m. until 11 p.m. on Sundays. A“real-time” task is one that essentiallyjust “occurs” when needed as often asneeded.

To provide a bit more depth, a good ques-tion to also ask is: why InvisiTasking? Toanswer that it is important to understandwhy IT tasks are scheduled in the firstplace. That is, what is the problem thatscheduling solves? Obviously, a sched-uled task is one that is deemed impor-tant enough to occur; such as databackup, virus scans, or defragmentation.It is also scheduled because doing sucha task manually is either time-consumingor counter-productive. Nobody wants tobe in the office on Sundays at 10 p.m.(unless you’re a workaholic) to manuallyrun your backup software, and nobody isgoing to stop working in the middle of theday to run a manual anti-virus scan ordefrag, because it takes the user/com-puter away from it’s true purpose—highamounts of production. In comes “sched-uling” as a better-than-manual solution.So the next question would then lead into“Why are these scheduled jobs run atnight/off-hours?”

IT has invented all these advanced tech-nologies such as Wake On LAN (WOL), towake up boxes at night to update themwith new fixes, run AV, etc. All theseactions and motions have been createdto explicitly avoid running these “back-ground” tasks during production times.Again, we need to ask ourselves why?Why all this effort from hardware andsoftware vendors? While there isn’t one

perfect answer, the basic premise of anIT person’s response would be com-posed of either 1. “these process heavilyimpact the daily production of the work-station or server and must be done onsystem down-time” or 2. “company policystates that for unpredictable incompati-bility, two processes are not allowed torun simultaneously” (i.e., nothing isallowed to run during production hoursexcept programs explicitly related to pro-duction, such as the company’s enter-prise resource planning systems soft-ware or their Office app suite). That situ-ation likely can be traced back to someevent where some programs buttedheads and caused a major business-related issue (like the “mail server wentdown for the day”). It is unfortunate to bein this situation, because it can berestrictive to the ideal environment (for ITstaff) from a performance and securityperspective, but I do understand it.

InvisiTasking is intellectual property (IP)innovated and owned by DiskeeperCorporation. I won’t go into depth on howit works here, or why it is better than out-dated efforts such as throttling, as thereare other articles and papers on it already(see article on pg. 6), but in short, itsolves the technical issues that requiretasks to be scheduled off-production.

What are the benefits of real-timedefrag?There are two benefits that stand outimmediately. The first is continuous peakperformance. Diskeeper is able to elimi-nate fragmentation as a performanceimpediment throughout the day. It is vigi-lant but not to the point of overdoing it;and, of course, guarantees that it never,ever interferes with production tasks.This is important as users are most likelyto access fragmented data within a short

time of creating or modifying the data.Diskeeper is active in defragmenting thedata, but as mentioned, not overactive.We know very well that data is likely toreside in cache for a period of time, sothe relative aptness to defragmentrecently fragmented data needs toaccount for this. And, of course, a gooddeal of data is deleted shortly after it iscreated, and would likely be pointless todefragment. These are all factors thatreal-time defrag takes into account in itsproprietary algorithms.

As part of my job, I frequently travel tovisit customers and get feedback on thesoftware so that we can continue toimprove it and help our customers. Thatleads me into the second benefit of areal-time solution that uses InvisiTasking.This is the one that really rings true withsystem administrators I speak with, andwhat they volunteer gladly with my ask-ing. InvisiTasking allows them a trulyhands-off program. They really don’t wantmore things to do at work—they’re plentybusy already. I hear, time and time again,that they don’t want to solve one prob-lem with another one. I like to translatethis into “just make the problem goaway.” No one wants another applicationto manage. Granted this is somethingprobably few IT staff are familiar with, butthis, at its core, is what solutions devel-opers want to provide to customers.

Do you have to configure real-timefeatures or InvisiTasking inDiskeeper 2008?Not at all, but as I mentioned inresponse to the first question, there aretwo primary reasons, in principle, that ITpeople implement schedules. The firstpurpose (these processes heavilyimpact the daily production of the work-station or server and must be done on

5

system downtime) is entirely and com-pletely negated due to the revolutionary(sorry to sound marketing-ish with myadjectives here) InvisiTasking technol-ogy. As for the second (company policystates that for unpredictable incompati-bility, two processes are not allowed torun simultaneously) there is no technicalreason why Diskeeper cannot run onmission-critical live production systemsduring the day, but we cannot technicallysolve what simply may be a matter ofcompany policy. For that reason weadded a timeline configuration to disableDiskeeper during certain time periods. Iwould never recommend doing so,unless there is some policy that must beadhered to. Unfortunately, this meansthat systems won’t be at peak perform-ance while Diskeeper is disabled, butthose systems will likely be able to catchup during off-hours and be at peak forthe following morning.

It is difficult to measure the perform-ance value of real-time defrag without acontrolled environment using bench-marks gathered from a performancemonitoring solution such as Window’sPerfMon (you can measure physical diskcounters such as queued disk I/O andSplit I/Os). It certainly can be done, itjust takes time to establish baselinesand do a comparison. You’ll definitelysee I/O throughput improvements. Themore active the system, the more signif-icant real-time defragmentation will ben-efit. The key benefit of this technologythat is quite easy to calculate is themanagement overhead. A typically hid-den component of TCO is the amount ofstaff time and resources that end upbeing spent on the new app that isadded to the IT mix. All that time andeffort managing an app costs moneyand pulls staff away from the next proj-ect. If you’ve ever felt like there are toomany projects all going on at once, agreat deal of the time it’s because it isdifficult to really complete a project. Itdrags on and on, sucking up time. So, insummary, the very tangible benefit ofDiskeeper technology is substantiallybetter ROI with the elimination of appli-cation management overhead. “Set Itand Forget It” grows up to “Install It andForget It.” It’s a shame that slogan isn’tquite as catchy.

A New Storage AgeFor years computing demands havebeen pushing along Moore’s Law. That“law” is directly related to CPU comput-ing power and states that the number oftransistors per CPU doubles over certaintime intervals (12, 18, or 24 months—depending on when or where you heardit). However, in the new millennium thegrowth of data storage has been sorapid it is even exceeding the industrystandard growth index laid forth byMoore’s Law (any way you define it).The exponential growth of storagerequirements is driven by the Infor-mation Age, the public’s unquenchablethirst for information and the increasedcomplexity and size of applications,operating systems and data.Additionally, another huge influence onthe IT world has been government regula-tions such as Sarbanes-Oxley, the PatriotAct, Health Insurance Portability andAccountability Act (HIPAA) as well as theGramm-Leach-Bliley act. These regula-tions often govern documenting certainbusiness transactions and the retentionand security of all relevant data. Many inthe industry are required to store every-thing for periods as long as seven yearsto maintain regulatory compliance.Deleting files has become taboo.A booming storage industry has grown inresponse to this new age. Hard drivemanufacturers increase storage capaci-ties at rates that often keeps pace withtransistor count increases. Advancedstorage technologies such as StorageArea Networks (SAN), Network AttachedStorage (NAS), Storage Managementsoftware and E-mail Archiving solutionscontinue to fill the headlines.

Windows Disk Fragmentation More Relevant Than EverToday, the number of files stored on vol-umes is much greater than times past.This increased number of files not onlynecessitates larger storage capabilities

but due to inherent fragmentation prob-lems, puts a burden on file systems tokeep files stored contiguously.File systems need to be able to place filessuch that they have space to grow in acontiguous fashion. When files are cre-ated and deleted, unused space gets frag-mented and pieces of free space arespread through the disk. These frag-mented unused spaces encourage newfiles to be created in places where theycan’t grow contiguously. It also encour-ages the file system to put fragments oflarger files in these small free space gaps.As a general rule more files equal morefragmentation problems.Another fragmentation issue is theincreasing size of files. The typical Wordor PowerPoint document is bigger thanever. Additionally the use of video andgraphic files have become common-place and these files have grown to mas-sive proportions. Bigger files have anobvious connection to increased filefragmentation.Another general rule: bigger files equalmore fragmentation problems.With the exponential growth of storage,managing one’s backup windowbecomes a major challenge whendesigning storage architectures and set-ting backup practices. Handling diskfragmentation is vital to managingbackup windows when file level backupsare performed. Many system adminis-trators are battling the ever-expandingbackup window. In fact, it is not uncom-mon for file-based backup times toexceed 24 hours, driving StorageManagers to seek out continuous dataprotection, data segregation, expensivehardware, and other strategies, lest theyrisk data loss. Recent studies haveshown that defragmenting before back-ups are performed can decrease backuptimes by up to 69%1, often making a spi-raling issue, more manageable. At the

very least, it provides breathing room enroute to permanent solutions.

Not Just a Server IssueOne might mistakenly consider thatsince user files and data are stored onservers in the typical enterprise client-server environment, disk fragmentationdoesn’t occur fast enough to warrant fre-quent defragmentation jobs on desk-tops. Nothing could be further from thetruth. When managing storage devices ina client-server environment it’s impor-tant to consider the files that are tem-porarily created on users’ local harddisks, and files that are backed uplocally by commonly used applications.Applications such as Microsoft Outlook,web browsers and many others createand use files in the background. Thesebackground files are very often heavilyfragmented and, since the user is run-ning applications that have to operatewith fragmented files, the user is reallyfeeling the performance degradation. The proliferation of high-speed networks(Gigabit Ethernet) and wireless technol-ogy has fueled a new mobile workforce.Corporate culture readily accepts work-from-home employees. Laptop salesnow commonly outpace that of the desk-top counterparts. The workforce, for allthe consolidation and centralization onservers, is becoming more widely dis-tributed in the workstation user popula-tion. For those segments, data distribu-tion and/or synchronization are anincreasing reality.

New Maintenance Practices NeededIn this new climate, it’s important to re-examine old beliefs and ensure our stor-age and system management practicesare sufficient for today’s environment. ITneeds to continually adapt to the changingdemands of the business and the user.Storage management is a crucial topic,and the need to defrag more frequently isnow more vital than ever before.

Real World Test Results onFragmentation LevelsAn experiment was performed using adesktop running Windows Vista in a typ-ical Monday through Friday businessenvironment which utilizes a file serverto store user documents. For this test,Diskeeper was installed and activated.

1 Improving Backup Performance with Defragmentation (A business application study), Diskeeper Corporation

The desktop user went about his normaljob-related activities for two weeks.Normal operations for the user included,Internet browsing (Mozilla Firefox), e-mail(Microsoft Outlook w/offline store), wordprocessing (Microsoft Word), spread-sheet (Microsoft Excel), and design(Adobe® Photoshop®, Microsoft Visio).Diskeeper had been in use on thismachine since inception all the way upuntil two days prior (Tuesday) to thebeginning of this test and had left themachine with fewer than 100 fragments(97—all excess allocations of files suchas the USN Journal). The test was begunon a Thursday, after the Vista defrag-menter had performed a custom sched-uled defragmentation job, using thedefragmenter UI, the night before. TheVista defragmenter had left 1,245 frag-ments after its run meant to address thetwo days of fragmentation buildup.The most heavily fragmented filesincluded a 2.5 GB Outlook file (this OSTfile was locally stored) and severalSystem Restore files. The majority offragmented files were part of the user’sprofile, affecting logon/logoff.A similar, previously published two-weekexperiment was conducted on WindowsXP, where the user used only Word andInternet Explorer (significantly less activ-ity). The results showed accumulatingfragmentation topping 4,000 fragmentsover the same period, with no native relief.

Test Lab ConclusionsAs demonstrated in the chart above,fragmentation levels rise quickly on thedesktop, resulting in performance beingdegraded each day. Cumulative weeklybuildup reaches more than 12,000 frag-ments each week.A weekly defragmentation job exposesthe system to performance liabilities.Relying on basic defragmentation func-tionality limited the effectives of a solu-tion, thereby affecting user performance.Even though this computer stores onlyvery few files locally, fragmentation willslow system performance and hurt user

productivity. Worse yet, as fragmentationlevels increase for larger files that arenot addressed, they will get up into lev-els where one can start experiencingreliability problems.Diskeeper was able to solve the fragmen-tation problem immediately, so dailybuildups (exceeding 3,500 fragments insome cases) was kept under control. Notethat this test can easily be re-created byinstalling trial software and viewing theDiskeeper History graph.Had this computer been a computer on which a great deal of power user datais stored (perhaps an attorney, field

Diskeeper’s Real-Time Really Solves ItNew advancements in Diskeeper evolvepre-scheduled (or even Smartly Sched-uled) defragmentation into the most pop-ular real-time performance solution inuse. Defragmenting in real-time, or on-the-fly as it is often referred to, providestwo very evident benefits.The first is continuous peak perform-ance. Diskeeper is able to eliminatefragmentation as a performance impedi-ment throughout the day. It is vigilant butnot to the point of overdoing it, and, ofcourse, guarantees that it never, everinterferes with production tasks (moreon this below). This is important, asusers are most likely to access frag-mented data within a short time of cre-ating or modifying the data.Secondly, advanced technology means,no administrative overhead of IT depart-ments—no replacing of one issue withanother.In a recent interview, Michael Materie,Director of Product Management forDiskeeper Corporation added this on thesubject:“Diskeeper is active in defragmenting thedata, but not overactive. We know verywell that data is likely to reside in cachefor a period of time, so the relativepropensity to defragment recently frag-mented data needs to account for this.And, of course, a good deal of data isdeleted shortly after it is created, andwould likely be pointless to defragment.These are all factors that real-time defragtakes into account in its proprietary algo-rithms. Another important point to make,the one that really rings true with systemadministrators, is that InvisiTasking pro-vides them a truly hands-off program.They really don’t want more things to doat work [managing defrag software]—they’re plenty busy already. They don’twant to add a new problem when solvingan old one. I like to translate this into‘just make the problem go away’… thisis what solution providers really shouldbe providing to their customers.”

Maintaining System UptimeSystem administrators using the manualdisk defragmenter built into WindowsXP/2000/2003 must wait for lengthydefrag jobs, which use up enough systemresources that it must be done off-line orafter hours. The Task Scheduler can beused to schedule jobs, but that itself

generates massive management over-head, and it still unlikely to solve the issueof fragmentation. Windows Vista and theupcoming Longhorn operating system pro-vide a basic pre-scheduled defragmenter,with some I/O resource improvements. Asthe study shows, fragmentation on Vistaincreases at a phenomenal daily rate. Farbeyond the rate previously experiencedwith earlier operating systems, hence it isunderstandable that Microsoft madeefforts to address this with their built-inutility. The weekly buildup tops 15,000fragments. As is also shown, fragmenta-tion is never truly eliminated in the weeklypre-scheduled job and actually accumu-lates from one week to the next. The prob-lem continues to exist, and it could beargued that on a day-to-day basis, theissue has actually worsened.On the other end of the spectrum isDiskeeper, the market-leading technologywith over a decade of system performanceinnovation. Diskeeper operates in real-time, invisibly in the background, thanks tothe proprietary innovation, InvisiTasking—the foundation for Diskeeper’s system per-formance processes.Given that CPU and I/O resources arealmost never fully utilized, InvisiTasking’stransparency is achieved by undetectablytapping into these unused systemresources. Attempts to share resourcesby choosing lower CPU priorities or throt-tling disk and network I/O cannot guar-antee truly transparent software, asInvisiTasking can.To accomplish true transparency,InvisiTasking accounts for CPU, memoryand the more significant hardware bot-tlenecks of the disk drive and network. Ittakes a proactive approach to instantlydetect resource usage while maintainingcomplete granular control over its ownactivity, ensuring that it never pre-emptsusers or services.

ConclusionIn today’s environment of bigger disksstoring not only larger files but morefiles than ever before, the effects offragmentation worsen markedly witheach day’s use. To keep up with same-day per formance degradation, disksmust be defragmented in real-time.

I use Diskeeper Enterprise edition over a Dell Powervault 745NNAS. This NAS is a central storage for all user documents; hereI host my Microsoft Exchange Databases. The NAS server alsoholds the attachments for my SAP Business One ERP system.We manage 2 TB of data in this server.I chose Diskeeper because only using the Windows defrag util-ity was a time-consuming task and the performance of the

server was compromised byfragmentation. Real-timedefrag has been very usefulon incrementing server per-formance and automaticdefrag eliminated the need touse support people to do thistask on a regular basis.Server performance hasimproved to such a degreethat we stopped the pur-chase of a new server andour users are very happywith the improved serverresponse time.

Diskeeper is very easy to use, has a straightforward install anda very small footprint. I like the transparency, monitoring andautomatic defragmentation. It’s fully automatic once the sched-uling is set up, and from then on it’s a real-time defrag.On our SAN we saw considerable performance increase—this isa definite plus over the slow degradation of performance withoutDiskeeper installed. We are using two Exchange servers (cluster)and one SAN.I’ve been a fan since the mid-’90s when Diskeeper was the onlydefragmenter available for our servers. We deployed the new ver-sion of Diskeeper to 71 servers. We had no issues at all. It wentvery smoothly. I do not anticipate a return on investment until alater date. We have not been spending a lot of time on defrag-ging most of these servers. The initial rollout of Diskeeper

saved us some money as we were having issues. The updatedversion just made everything easier.

I work from a home office on a Windows XP machine using pri-marily (from most to least) AutoCAD, IE7, Microsoft Office, andQuickbooks. I’ve had no problems with Diskeeper 2008. WhatI love most is the hands-free, real-time operation. Schedulingdefragmentation was a problem with earlier versions because Ispend so much time on the machine that it was hard for me tofind a time that didn’t interfere with my work. It’s really nice tobe rid of that headache. MFT defragmentation is nice, too.

I’ve been using Diskeeper for about a year and a half now. Ihave nothing but good things to say about it. Diskeeper hastaken the worry out of my life when it comes to keeping myHDD defragged.I just upgraded to the latestversion of Diskeeper… figur-ing it gets better with eachrelease. And I have recom-mended it to several of mycolleagues who have all pur-chased Diskeeper.Prior to using Diskeeper, I wasalways running at an averagefragmentation level of 25%. Ihave a lot of files (over100GBs worth) and am con-stantly adding/deleting filesand programs day-to-day. With a busy schedule it’s hard toremember or take the time to defrag my machine; plus, when I didrun defrag, I had to make sure I ran it at night before going to bedas it would kill my machine’s performance when it was running.With Diskeeper, I don’t have to worry about any of that. It runs inreal-time, is always keeping my machine defragged and doesn’tslow down my machine at all. Now, I average a fragmentationlevel of about 1% and don’t even think about fragmentation onmy HDD now that I have Diskeeper installed.
