From time to time, misconceptions sneak in to some data centers about fragmentation and its impact on modern disk storage technology such as SAN devices. The thinking is that fragmentation is not an issue. Nothing could be further from the truth.

We’ve thoroughly investigated and found in every case that failures to bring the data storage to the state of zero fragmen-tation will lead to slowdowns, increased maintenance issues and more administrative issues than an IT manager should have to afford. The increase in operational costs is normally far more than what it takes to roll out Diskeeper 2010 sitewide.

Diskeeper Corporation spends a large portion of its resources on research and development to isolate real workplace performance and reliability issues and develop cost-effective solutions that can be automatically deployed and run.

As a customer, you know that our value as a company is in the quality of the help we deliver. We have the track record and testimonials that prove we excel at this.

This issue of Newskeeper begins a series of technical reports on why a full roll-out of Diskeeper across all the servers and workstations is rightfully a best practice. Our feature article focuses on Storage Area Networks (SANs).

What we found will likely surprise you.

Peter Mead, Editor editor@diskeeper.com

I have installed the new Diskeeper 2010 version on our CRM and SQL servers and have noticed a huge decrease in response times from the systems, as well as ease of mainte-nance and overall reliability of the servers. It keeps fragmenta-tion down to the bare minimum even better than the previous versions. I love it. It makes a huge difference on CRM servers. Where I saw the most improvement was in the response to requests from sales. Since the system wasn’t all fragged up, it made at least a 40% increase in speed for query-to-CRM records and, even with me doing reports, Diskeeper helps out the response times for the whole environment.

— Douglas Morgan, CIO, Candy Bouquet Int’l., Inc.

Diskeeper 2010 is increasing system reliability. It ensures that we don’t experience outages caused by the inability to perform a defrag of a hard drive which incurs unacceptably large maintenance windows to manually perform multiple defrags, and still not accomplish the job. With Diskeeper, I simply install, review the configuration, modify if necessary and check up on it about once a quarter—maybe. It is impressive to see that fragmentation is non-existent. I simply can’t think of a better, more reliable, and simple tool to implement in a large corporation.

f e at u r e a rt i c l e

A SAN affords the administration the ability to make remote disks appear to be local. It does not matter what protocol they use to connect: ISCSI, Fibre Channel, etc.

SAN storage units are referred to as LUNs. Originally the term LUN (Logical Unit Number) only meant the SCSI disk address on an array for a particular disk, but it is now commonly used to represent the physical disk array when it is implemented in a SAN as a logical volume(s).

san storage Virtualization

Storage virtualization involves the creation of a usually very large, logical pool of data. Via software, that pool appears to be physically located all on one server. In actuality, that data may be located across hundreds of physical disks spread across dozens of servers. This is the concept implemented by Storage Area Networks.

This technology abstracts “logical storage” (the file system —what the operating system sees and uses) from physical storage devices and combines it into one large grouping on top of which a virtual storage container is created.

SAN file systems such as VMFS from VMware or EMC Celerra are known as shared-disk file systems and are the backbone of storage virtualization. An operating

system defragmenter only recognizes the “local” disk file systems that it natively supports. Vendors of proprietary file systems typically include specialized technologies to optimize performance. These file systems are the foundation for storage virtualization.

i/o mapping and redirection

Storage virtualization uses metadata to properly channel I/O. Software on a storage virtualization device (such as a SAN Switch) will translate logical disk locations to physical disk ones.

For example:

• A storage virtualization device gets a request for a logical location of LUN #1, LBA32.

• It then performs a metadata lookup for that address and finds it actually maps to LUN#4, LBA16

• The device then redirects the request to the actual physical location of the data.

• Once it retrieves the data, it passes it back to the originator without the originating requestor ever knowing that the request was completed from a different location than what it knew.

The fact that there is not a one-to-one mapping of file system clusters to LBAs (due to LUN virtualization) is not an issue. Logical file system level fragmentation causes the operating system to generate additional I/O requests to the virtualization software. Using metadata, the SAN then redirects I/O from the logical disk to its physical location.

The local disk file system does not know of and cannot control the physical distribution or location in a virtualized storage environment and, as a result of fragmentation, NTFS has to make multiple requests

The SAS (Serial Attached SCSI) software does not know

what the total size of a file will be when it is created,

therefore, it cannot be contiguously allocated. File

fragmentation is a problem because additional file

system activity must take place to access a file that

is stored in multiple, noncontiguous locations on a

volume. When defragmenting a volume, all the files on

the volume are rearranged so that each file is in one

contiguous extent.

Vo lu m e 4 | i ss u e 1 7 5

regardless of the physical or virtualized storage environment.

In SAN fi le systems, block size (the smallest addressable virtual unit) is a confi gurable metric and varies based on the software used. VMware VMFS, for example, supports 1 MB to 8 MB blocks.

Logical Cluster Numbers (LCNs) are a fi le system construct used to map a fi le on a volume to LBAs. Disk controllers take those logical blocks and make the appropriate translation to a physical location. Disk controllers do not, no matter how “smart” they are, independently map fragmented fi le I/O into consecutive or linear block requests. They cannot “pool” incoming block-based data back into a fi le.

SANs can offer extremely effi cient and high-performing data storage, but it is not the job of a SAN system to address fi le system level fragmentation. Proprietary technologies employed by one vendor can be more effi cient at retrieving data blocks than another. Architectures can vary as well. No matter how effi cient data retrieval can be, and how much physical disk limitations can be mitigated, the overhead on the operating system is impacted by fragmentation and beyond the scope of SAN technology. Local disk fi le defragmentation is still necessary.

using resource-sensitive

technologies to throttle activity

In cases where multiple operating systems (multi-headed) connect to common shared disks, as in a SAN, I/O throttling techniques will not function appropriately. The case being that an application using I/O throttling may detect that a shared disk array is not busy, but a secondary server also using that same array may be processing a very disk-intensive operation. In that event disk contention may occur.

recommendation

Only Diskeeper 2010 provides fi le system drivers that prevent most fragmentation at the source (the fi le system) with a fi le write. This is an excellent solution in a SAN environment as it lowers the added overhead spent in after-the-fact removal of fragmentation.

Proprietary technologies such as InvisiTasking® technology, which eliminates defragmentation overhead on direct attached storage, will provide more effective resource-sensitivity for storage networks through granularity of its actions. With the possibility of overhead confl ict in more I/O-demanding SANs, it is still recommended to undertake a proper evaluation of the environment to determine if defragmentation time frames are better suited to off-peak production hours.

and it has increased our disk performance by a factor of

but this wonderful software did it for us.

a neW storage ageFor years, computing demands have been pushing along Moore’s Law. That “law” is directly related to CPU computing power and states that the number of transistors per CPU doubles over certain time intervals (12, 18, or 24 months—depending on when or where you heard it). However, in the new millennium, the growth of data storage has been so rapid it is even exceeding the industry standard growth index laid forth by Moore’s Law (any way you defi ne it).

The exponential growth of storage requirements is driven by the Informa-tion Age, the public’s unquenchable thirst for information and the in-creased complexity and size of appli-cations, operating systems and data.

Additionally, another huge infl uence on the IT world has been government regulations such as Sarbanes-Oxley, the Patriot Act, Health Insurance Portability and Accountability Act (HIPAA), as well as the Gramm-Leach-Bliley act. These regulations often govern documenting certain business transactions and the retention and security of all relevant data. Many in the industry are required to store

everything for periods as long as seven years to maintain regulatory compliance. Deleting fi les has become taboo.

A booming storage industry has grown in response to this new age. Hard drive manufacturers increase storage capacities at rates that often keep pace with transistor count increases. Advanced storage solutions such as Cloud Storage, Storage Area Networks (SAN), Network Attached Storage (NAS), Storage Management (e.g., deduplication, thin provisioning) software, and e-mail archiving solutions continue to fi ll the headlines.

neW maintenance practices neededIn this new climate, it’s important to re-examine old beliefs and ensure our storage and systems management practices are suffi cient for today’s environment.

Take for example a modern enterprise SAN environment. Here, scheduled processing of fi les is increasingly more impractical, given the sheer amount (terabytes+) of fi les to manage. Alternative designs that function in real time only on fi le changes (at the block level) are increasingly more

commonplace. SAN snapshots are one such example of continuous data protection used to augment, or sometimes applied in lieu of, scheduled fi le backup.

Information Technology needs to continually adapt to the changing demands of the business. Storage management is a crucial topic, and the need to maximize the effi ciency of storage is now more vital than ever before.

disk fragmentation is more preValent than eVerToday, the number of fi les stored on volumes is much greater than times past. The increase in the number of fi les not only necessitates larger storage capacities but, due to inherent fragmentation problems, puts a burden on local disk fi le systems to keep fi les stored contiguously.

As fi les are deleted, the space the deleted fi les formerly occupied will be randomly spread across the disk(s). These non-contiguous segments of available space encourage new fi les to be created in places where they can’t be written contiguously.

As a general rule, more fi les equal more fragmentation problems.

Is Fragmentation Prevention Needed in Today’s Environment ?

Vo lu m e 4 | i ss u e 1 7 7

Another fragmentation issue is the increasing size of files. The typical Word or PowerPoint® document is bigger than ever. Additionally the use of video and graphic files have become commonplace and these files have grown to massive proportions. Bigger files have an obvious connection to increased file fragmentation.

Another general rule: bigger files equal more fragmentation problems.

With the exponential growth of stor-age, managing one’s backup window becomes a major challenge when designing storage architectures and setting backup practices. Handling disk fragmentation is vital to manag-ing backup windows when file level backups are performed. Many system administrators are battling the ever-expanding backup window. In fact, it is not uncommon for file-based backup times to exceed 24 hours, driving storage managers to seek out continuous data protection, data segregation, deduplication, expensive hardware, and other strategies, lest they risk data loss. Recent studies have shown that defragmenting before backups are performed can decrease backup times by up to 69%1, often making a spiraling issue more manageable. At the very least, it provides breathing room en route to permanent solutions.

not Just a serVer issueOne might mistakenly consider that since user files and data are stored on servers in the typical enterprise client-server environment, disk fragmentation doesn’t occur fast enough to warrant frequent defragmentation jobs on desktops. Nothing could be further from the truth.

When managing storage devices in a client-server environment it’s impor-tant to consider the files that are temporarily created on users’ local

hard disks, and files that are backed up locally by commonly used applica-tions. Applications such as Microsoft Outlook, web browsers and many others create and use files in the background. These background files are very often heavily fragmented and, since the user is running applications that have to operate with fragmented files, the user is really feeling the performance degradation.

The proliferation of wireless technology and improvements in security have fueled a new mobile workforce. Corporate culture more readily accepts work-from-home employees. Laptop sales now commonly outpace that of the desktop counterparts. The work-force, for all the consolidation and centralization of servers, is becoming more widely distributed in the work-station user population. For those segments, data distribution and/or synchronization are an increasing reality.

real World test results on fragmentation leVelsAn experiment was performed using a desktop running Windows Vista in a typical Monday through Friday business environment which utilizes a file server to store user documents. For this test, Diskeeper was installed and allowed to perform reactive defragmentation

(i.e. defragment data that is written in a fragmented state). The desktop user went about his normal job-related activities for two weeks.2 Normal operations for the user included, Internet browsing, e-mail, word processing, spreadsheet, and design.

The most heavily fragmented files included a 2.5 GB Microsoft® Outlook® file (this OST file was locally stored) and several System Restore files. The majority of fragmented files were part of the user’s profile, affecting logon/logoff.

A similar previously published two-week experiment was conducted on Windows® XP, where the user used only Word and Internet Explorer® (significantly less activity). The results showed accumulating fragmentation topping 4,000 fragments over the same period.

As demonstrated in the chart, fragmentation levels rise quickly on the desktop, resulting in performance being degraded each day. Cumulative weekly buildup reaches more than 12,000 fragments each week.3 That is fragmentation that a weekly defragmentation job such as on Windows Vista and Windows 7 does not address.

1. Improving Backup Performance with Defragmentation (A business application study), Diskeeper Corporation 2. Diskeeper had been used to fully clean up fragmentation on this system up until two days prior (Tuesday) to the beginning of this test and had left the machine with fewer than 100 fragments. The test was then begun on a Thursday, after the Vista built-in defragmenter had performed its default scheduled defragmentation job the night before. The Vista defragmenter still left 1,245 fragments after its run, which was meant to address only the prior two days of fragmentation buildup (since Diskeeper had been removed).

WHAT INDUSTRY OPINION LEADERS HAVE TO SAY ABOUT DISKEEPER DISK PERFORMANCE SOFTWARE

DISKEEPER WORLD NEWS

“Diskeeper looks to solve the problem of fragmentation

with Diskeeper 2010, an application that intelligently

writes fi les to disks and prevents fi le fragmentation in

the fi rst place. The Diskeeper 2010 IntelliWrite feature

accomplishes this task by helping IT workers avoid the

task of manually defragging or even having to schedule

maintenance. Diskeeper 2010 with IntelliWrite is

designed to not only avoid unnecessary maintenance

time spent by employees, but also to reduce energy

and cooling costs by maximizing system effi ciency.

If disks do not have to work hard writing fragmented

fi les to the disk, they’re spinning less, consuming less

power, and generating less heat. Further, with less

use, drives will last longer, providing a better ROI for

companies and reducing overall hardware costs.”

Seth Colaner Processor

“Diskeeper is a long-time player whose main focus is large corporations who really need to save time and money. This is where the money is and it’s also where the payoff is huge in terms of a green product. Diskeeper’s revolutionary ‘stop defrag before it happens’ qualifi es it as a green product because it reduces disk drive wear (possibly extending life of drive before it goes into the recycle heap) and also reduces energy consumption by making drives more effi cient. This seems to be missed by the mainstream computer media.

“I recently installed Diskeeper 2010 and I am a fi rm believer. Diskeeper does more than up the bar by providing fantastic speed gain on defragmentation.”

Even though this computer stores only very few files locally, fragmenta-tion will slow system performance and hurt user productivity. Worse yet, as fragmentation levels increase for larger files that are not addressed, they will get up into levels where one can start experiencing reliability problems. Had this been a computer on which a great deal of data is locally stored (perhaps an attorney, field engineer, or salesman’s note-book) the degree of fragmentation would most certainly be higher, and cause an even more significant impact to productivity.

eVolution and intelligent designOver the years, the Diskeeper system performance solution has evolved from simple fixed schedules to heuris-tic scheduling to real-time defragmen-tation. However, when fragmentation occurs, the system is wasting precious I/O resources by writing non-contig-uous files to scattered free spaces across the disk. The best strategy is, deviating from the evolutionary path, a truly revolutionary one: prevent the problem from ever happening in the first place.

The exclusive IntelliWrite™ technol-ogy does just that. Its design prevents fragmentation (up to 85% of it) from being written to the hard drive by writ-ing the files intelligently. The benefits are readily evident: continuous peak performance, and no administrative overhead for IT departments.

Consider again the above test case. Instead of 3,500 fragments a day, a system with IntelliWrite technology generates only 500 or so fragments. Those 500 extents are quickly corrected a few minutes after the fact with additional advanced real-time technology exclusive to Diskeeper.

maintaining system uptimeSystem administrators using the manual disk defragmenter built

into Windows XP/2003 must wait for lengthy defrag jobs, which use up enough system resources that it must be done off-line or after hours. The Task Scheduler can be used to schedule jobs, but that itself generates massive management overhead, and it is still unlikely to solve the issue of fragmentation. Windows Vista/7/2008/R2 all provide essentially the same basic built-in pre-scheduled defragmenter. As the test cases show, fragmentation increases at a phenomenal rate. Far beyond the rate previously experienced with earlier operating systems, hence it is understandable that Microsoft has made efforts to address this with their built-in utility in newer versions of Windows. The weekly buildup tops 15,000 fragments. As is also shown, fragmentation is never truly eliminated in the weekly pre-scheduled job and actually accumulates from one week to the next. The problem continues to exist, and it could be argued that on a day-to-day basis, the issue has actually worsened.

On the other end of the spectrum is Diskeeper, the market-leading solution, with over 16 years of system performance innovations for Windows file systems. Diskeeper invented automatic defragmentation for Windows in the mid-1990s, and maintains innovative leadership to this day as the only solution to prevent fragmentation.

conclusionIn today’s environment of bigger disks storing not only larger files but more files than ever before, the ef-fects of fragmentation worsen mark-edly with each day’s use. To eliminate the window of performance loss (between defragmentation cycles), eliminate wasted I/O resources and maximize file write performance, frag-mentation should be prevented.

Simply put, every file system fragments and turns the hard disk into a bigger bottleneck than it already is. Throughput suffers. Today’s modern technologies require consistent performance and are focused on interoperabil-ity, convergence and compatibility. Maintenance requires fast backup times, less backup failures, automatic solu-tions, less help desk calls and lower overhead. Fragmen-tation affects every one of these areas on every network.

Here is a sample of feedback we’ve received from our customers who have rolled out Diskeeper to their entire network.

“We have been very pleased with our decision to deploy Diskeeper companywide. After the Diskeeper deployment our Service Desk received a number of calls from users ask-ing why their systems were so much faster. These are the type of calls we love to take! Our experience with Diskeeper has been overwhelmingly positive. Users are happy, and support people love it. Our Diskeeper deployment started shortly after our Office 2007 deployment. After Diskeeper was installed, the success rate of our Office deployment increased and post deployment calls went down.” — S.H. (a major food manufacturer)

Client Solutions – Architecture and Customer Experience Manager

“Diskeeper is a great product. We had 30% of our servers that were upwards of 80-90% fragmented. Now we have only about 1% and that is mostly because of free space issues. All our servers are RAID servers and we have a couple that are SAN attached. We have some that are SQL

servers. Overall, Diskeeper has improved performance. In the Desktop area we have quit worrying about drive fragmentation.” — J.B. (a major food manufacturer)

Enterprise Desktop Administrator

“We like Diskeeper because of the ‘set it and forget it’ deployment. It gives us peace of mind. It was a daunting task to defrag before and it wasn’t being done network-wide. All-in-all, Diskeeper is a positive addition to our network support tools.” —T.P. (a major supply company)

“Because of the benefits that we were seeing with Diskeeper on our servers, we decided to purchase and de-ploy Diskeeper to all of our PCs as well. Our helpdesk staff no longer have to manually defrag the PC hard drives, which ultimately is saving the company time and money, and the technicians can spend their efforts on more criti-cal issues.

“Overall, we are very pleased with the benefits that running Diskeeper has provided. The administrative console makes it very easy to manage the scanning policies, licensing, installation and just about everything else related to Dis-keeper. Our hard drives are getting defragged regularly and reliably, and we no longer have to spend hours monitoring and/or manually defragging them.

“Our servers and many of our PCs had degraded perfor-mance due to fragmentation, a problem I am happy to say we don’t have any more because of Diskeeper.” — Faye Jasman

Network Administrator Canal Insurance Company

“Diskeeper continues to play an important role in keeping both client and server systems optimized for peak perfor-mance with minimal management. We see a daily benefit from the InvisiTasking feature, which keeps our systems disks optimized using resources during idle times to insure maximum performance with minimal impact to users.

“The Diskeeper Administrator allows us to keep our systems in check, minimizing interruption to users and optimizing IT maintenance activities. I would recommend Diskeeper to anyone responsible for maintaining computer systems.” — Eric Carel, Network Systems Supervisor, Baldwin
