All Things PerfectDisk and Defrag

                                                 

Last year, Kansas-based William Newton Hospital, which serves a community of 40,000 people and has revenues of over $40 million, made the switch to PerfectDisk to improve its virtualization performance. The hospital looked to PerfectDisk's virtualization defrag solutions, which include tools for vSphere performance and Hyper-V performance improvements. William Newton Hospital maintains physical and virtual servers for database functions such as electronic medical record keeping, financial, inventory, lab and radiology information, and Point of Care charting. Medical Verification is also used at patient bedside via wireless Chart Carts and PDAs, along with a radiology image storage and retrieval system.

The big appeal, according to IT director Randy Mayo was PerfectDisk's unique Virtual Awareness capability, which eliminated "the severe system slowdown on our servers that we were experiencing with Diskeeper." As Randy points out, "PerfectDisk automatically determines guest and host activity to eliminate resource contention and minimize the impact on our shared storage. The result is faster systems, improved productivity and better service to our patients.”

                                             

But William Newton didn't stop there, as they continued to look to Raxco Software for performance and productivity improvements. This investigation led them to PerfectSpeed, Raxco's tool for boosting performance as well as cleaning up performance-debilitating clutter. While its typical use is for the home consumer, William Newton found so many useful tools for slow PC fixes and slow PC performance in PerfectSpeed that they've put it on over a hundred employees' computers. For these users, Mayo gets not only the benefit of the best defrag software, but also a powerful duplicate file removal program and one of the best registry cleaners, all helping speed up PC performance and ensuring these computers run at peak performance and efficiency.

From virtualization performance to an easy slow PC fix -- William Newton Hospital has found its fix.

                                             
 

Sometimes it's fun to take a step back from all the file system, slow PC tips, and Hyper-V performance counters talk and see how the best defrag software tool plays out in the real world. On its own, a server defrag may seem a little drab. But if you see how it's helping a baseball team, well...that can make it a little more interesting.

                                                    

The Greater Des Moines Baseball Company is the umbrella company for the Iowa Cubs minor league baseball team of the Pacific Coast League. Recently, the Cubs selected PerfectDisk 11 Server to boost its servers’ performance through disk defragmentation. The Cubs, with several hundred employees serving an annual attendance of over 500,000, use its servers for ticketing, merchandise sales, food and beverage sales, video boards and score boards, video production, financial and back office functions, and database management. The team's servers have several physical and virtual servers on Windows Server 2003 and Windows Server 2008 to run the business. Prior to selecting PerfectDisk over a competitive product, the Cubs used the Windows built-in disk defrag utility, but it was not up to the task. “Microsoft’s built-in defragmenter did not really accomplish much in terms of improved performance for our server, plus it was very slow,” said Larry Schunk, Chief Technology Officer at Greater Des Moines Baseball. “With PerfectDisk, our servers are running faster than ever, which means all our employees are more productive; in addition, its automation and powerful reporting tools provide a great value.”
                                        

You can see the complete press release of the Cubs server defrag selection here. 

Play ball. Win. Give your servers a good server defrag with the best defrag software.

The Cubs are in first place. Coincidence? That's crazy talk.

                                                             

We had a nice win recently. Easter Seals Hawai’i, after comparing PerfectDisk with another solution, chose the PerfectDisk 11 Hyper-V Bundle to boost its Hyper-V performance. The key decision drivers? Automation, Virtual Awareness and user-friendly licensing options (i.e. host-based) for virtualization environments.

You can read the press release here. Virtualization defrag to boost Hyper-V performance -- paradise.

                                             

When trying to figure out how to make your PC run faster, many people turn to look for the best defrag tool and best PC optimizer. Look at reviews, head to the user forums, ask their colleagues and friends to see what the options are. Free or paid for. Automatic or manual. Lots of options or few. Enterprise defrag or for personal use only. It's all well and good, and what drives us here at Raxco to deliver the market's best defrag software year after year.

                                               

But we also like to differentiate ourselves in a different way, through our technical support and customer service. So while we truly believe PerfectDisk is the best defrag software available, we also think our service and support are superior as well. That attitude is epitomized by Wendy Clontz, who heads up our customer service department and whom we are proud to have with us.

Dan Baldry is a 20--year IT professional in Sydney, Australia, managing a team of people who sell maintenance and professional services for one of the world's largest networking companies. Dan wrote to me directly recently about what he described as our "excellent service," which he argues is hard to find these days. Here are some of Dan's words: 

                                                

"I purchased Perfect Disk a few years ago mainly on the basis of an article I came across in a local PC magazine that I thought gave a good impartial review and sold me on the merits of the product. With a computing background, to me disk defragmentation is what I would describe as a routine housekeeping item that I would consider baseline for a healthy PC. In a perfect world this would be delivered as a native part of the operating system. You might argue that it is, but I'm suspicious of the standard utility  and a bit wary of the available freeware (though I know they are reasonably good). With my hard disk capacity getting bigger, I was on the hunt for a good utility that would just do the job and I could be confident in (no doubts), so that was why I decided to stump up the dollars and go for Perfect Disk. In short, I wanted to be sure my system was at optimum health and running with maximum performance all the time. You might ask why? Well, I use my PC  for a mix of work and play and it became a bit of a mission to drive the best performance without resorting to a massive/expensive upgrade as time went on. A few dollars on PD seemed like a good option. Eventually I did upgrade but I still use PD as part of the same housekeeping approach.

However, over the past couple of years, with reinstalls, losing keys, lost downloads etc... and needing to call on support more than once came to realise that the Raxco company offered me an extension of the confidence that I had in the product, and that was the confidence that if I had an issue I would get a reasonably quick, no nonsense, response. Even though it was probably only a few interactions over something like 24 months, I realised it was the same people assisting me throughout, which made me feel the company must have something going for it to be able to retain people like that. The consistent message I hear back is that while customers choose our physical products to drive their business based on value and the vision of our company, it's the Services we offer that keeps them coming back. Not only that, but our partners value our Services above all for the profitable revenue it drives - and customers are willing to pay as they have confidence that they are getting a total package. I think it's how we treat our customers after the sale that creates real business, and I think that's something Raxco has understood from the get go."

                                                 

It seems you can't visit a technology web site or pick up a trade publication today without seeing - oh - 1 to 10 articles on the ubiquitous cloud. Pity the poor, forgotten client PC. It seems nobody cares about it any more. Do they? Should they?                      

Daniel W. Rasmus, author of Listening to the Future (Wiley, 2008), is a strategist who helps clients put their futures in context. He uses scenarios to analyze trends in society, technology, economics, the environment, and politics in order to discover implications used to develop and refine products, services, and experiences. Prior to starting his own consulting practice, he was the Director of Business Insights at Microsoft, where he helped the company envision how people will work in the future. Rasmus coordinated the Microsoft Office Information Worker Board of the Future, an advisory panel composed of college-aged students who share ideas on how to better serve the “Millennial Generation” as they join the workforce. He also managed the Center for Information Work, an immersive experience that helped Microsoft's customers experience the future of work first hand.

His achievements include inventing conceptual frameworks for next-generation collaboration, adaptive workspaces, and intelligent content services. He also served as Giga's Chief Knowledge Officer, managing internal learning within research, sales, and marketing.

Writing on the Internet Evolution website yesterday, Rasmus wrote the article It's Time to Think About Clients, Not Clouds. He asks the question -- "as computers gain more processing power, has the move to the cloud forced us to abandon higher goals for the client?" Rasmus points out that most of a computer's power is used when you sit before it, and writes:

Think about that. When you turn your computer on in the morning, it is no different than it was the night before. Even if you leave the computer on, the most you can hope for is a completed backup, a few patches, a new RSS feed or two, a complete local index, perhaps a hard drive defrag.

Well, there you have it. Yes, computers do a lot of nothing when their owners or users are not driving them. They sit there, waiting for the next user command so they can go off and do whatever it is the user wants. To defrag a computer or defrag hard disk may not be the most important PC issues for many people (although we think it should be!), we're proud that we are one of the few applications that can give the client PC a boost when you're not sitting in front of it. Whether you want to fix a slow PC startup or obtain overall faster PC performance, applications like PerfectDisk and PerfectSpeed address the issues when your PC is idle and not consuming any CPU. Auto defrag when your computer is otherwise idle, through StealthPatrol. It works, even when you're resting.

Those of you who have followed us for at least the last couple of years have observed our entry into the virtualization performance space. As we pioneered technology such as PerfectDisk's patent-pending Virtual Awareness for vSphere performance and Hyper-V performance tuning, we've talked directly to hundred of enterprise and small business users. We've received lots of feedback on both the technology as well as the business side -- licensing and pricing.

In ComputerWorld today, Elisabeth Horwitt has a piece on Virtualization and software pricing: Very tricky. Elisabeth raises several interesting points, including:

Virtualization can provide significant TCO savings for server and desktop hardware, and in desktop software and security administration. But saving on software license costs through virtualization is problematic. For one thing, vendors can't seem to agree on a model that works for both them and their customers, says Amy Konary, a research director at IDC.

Many enterprise software vendors still charge per hardware box, which means customers can save by consolidating applications on a single server that has multiple CPUs. However, a growing number of vendors, such as Oracle, charge per CPU, says Altimeter Group partner Ray Wang. 

                                                

For a time, we had internal disagreements as well. And we've modified our pricing since moved into the virtualization space. But as we continued to talk to organizations, we finally came to a pricing model that we are very comfortable with, as are the businesses and government agencies that are customers of PerfectDisk's virtualization performance products. This pricing model has been with us now for several months. Companies that have been with us for years know we try to be their partner in the performance management aspect of their business. And because cost savings are a key motivator for moving to virtualization, we didn't want to be an obstacle to that goal. So we charge by the hardware box, which, as analyst Ray Wang notes, means customers can save money.

Many factors come into play as organizations move to virtualization, or look to maximize its benefits once they have moved. Virtualization performance is a key aspect of the process. After all, the potential cost savings don't mean a lot if performance degrades. As IT delves into the environment, it usually learns that all the problems associated with the Windows environment at the physical level haven't gone away. In fact, they may have multiplied because of the very nature of the host/guest relationship and interaction. Since they are so entwined, if the relationship between host and guest do not account for each other, virtualizaton performance suffers, with the resulting negative impact across the board.

Despite the obstacles and potential pitfalls, virtualization can, in most cases, provide numerous benefits. One of those is cost. We look to help organizations maximize the benefits with improved performance, without the downside of screwing the customer on the pricing side.

Virtualization performance via vSphere defrag and Hyper-V defrag -- you can get premier performance without paying a premium price. 

                                                  

 
 

The PerfectDisk 11 Client and Enterprise Console have been updated to Build 178. These latest builds include various bug fixes and minor enhancements.

You can “Check For Updates” in the products or wait for Autoupdate.

Client enhancements and fixes: 

• We corrected a bug when creating Auto Pilot schedules for Exchange Data stores on Exchange 2010. If individual stores were selected instead of all stores, you would get an error.
• A new feature was added to allow controlling the behavior (display) of the registration dialog. This can now be blocked using group policy, the config.ini file or the Enterprise Console
• A new feature was added to control the VSS settings from Group Policy or the config.ini file.
• A new feature was added to control the custom SMARTPlacement settings from Group Policy.
• We modified the behavior of the Screen Saver Auto-Pilot schedule to allow the monitor to power off. Prior to this version, Screen Saver schedules would not run if the monitor powered off as not screen saver was present. This behavior was modified to recognize the corporate need to have monitor power down to save energy.
• The defragmentation logic was modified to minimize skipping files during a defragmentation pass. Prior to this version a file could be skipping after failing to move when requested. This logic was changed to only skip the file under more restrictive terms.
• We corrected a flaw in the SmartDefrag logic where the proper defragmentation algorithm was not always being used.
• We added support for Japanese translations.

• When deploying patch files from the Enterprise console, the wizard would sometimes crash due to an un-initialized variable. This has been fixed.
• We corrected a bug when downloading the latest PerfectDisk clients for deployment. The console did not use the proxy settings. This has been fixed.
• New feature was added to allow controlling the behavior (display) of the registration dialog. This can now be blocked using group policy, the config.ini file or the Enterprise Console.
• We corrected a bug when downloading PerfectDisk client packages from the deployment wizard. Previous versions did not support saving the package to a network share. This has been fixed.
• A change was made to the deployment wizard to use the computer name if a domain is not specified when providing credentials.
• Some user interface layout changes were made to avoid confusion.
• We fixed a bug when specified specific sync periods which spanned midnight.
• We added support for Japanese translations.

                                          

Redmond Magazine recently reported a problem with Windows 7 and video performance, where the VC-1 video codec does not use all of the cores in three-core and six-core machines. What does this mean? Well, if you've purchased a new computer with Windows 7 for better graphics and video support, you may not be getting all you signed up for. For example, Blu-ray disc players aren't leveraging the power of some multicore machines running Windows 7.

The issue may also affect Xbox 360 game consoles, which also use VC-1, as well as a few other video codecs. Codecs compress and decompress media files. Most computer users probably don't care about them, as long as the video frames run smoothly. But many do.

As Redmond reports, there's no word from Microsoft on when the problem with the VC-1 video codec in Windows 7 will be resolved.                                           

In the meantime (and afterward), thousands of videographers, graphic designers and the like turn to thorough disk defragmentation to boost their video performance. Particularly when you're doing lots of editing, with large files changing and being deleted, video performance can take a big hit. That's why so many of them turn to defragmentation utilities like PerfectDisk to keep video performance humming along.

Fast defrag. Faster defrag performance. All leading to better video performance.

This is the concluding post on whether there a need for an SSD defrag, from Greg Hayes' recent white paper.

                                                    

To maintain SSD write performance, SSD manufactures implement one or more of the following techniques:

Wear Leveling
The SSD controller keeps track of how many erase cycles have been performed on each flash block and dynamically remaps logical to physical blocks to spread out the wear over all the cells in the drive. This means that no one portion wears out faster than another - prolonging the life of the SSD.

Over Provisioning
Over Provisioning provides extra memory capacity (which the user can't access).  The SSD controller uses these "extra" cells to more easily create pre-erased blocks - ready to be used in the virtual pool.

TRIM
TRIM allows the SSD controller to remove data from deleted cells so that the next write won't have to move, erase then write.  This allows an SSD to maintain write performance for a longer period of time.  In order for TRIM to be effective, it has to be implemented in the SSD itself as well as in the Windows operating system. Currently, TRIM is only implemented in Windows 7 and Windows Server 2008 R2.

PerfectDisk and Benefits to SSD storage
With SSD storage, since file level fragmentation results in negligible performance degradation, traditional file-based defragmentation really doesn't provide any performance benefit and should be avoided, as it has the potential to ultimately degrade SSD write performance. What can provide a performance benefit is free space consolidation to eliminate free space fragmentation and consolidate partially full blocks of data. High free space fragmentation is a strong indicator that a high instance of un-TRIM'ed, or partially full blocks exists. 

While free space consolidation can help improve write performance, free space consolidation is not something that typically needs to be done on a frequent basis. PerfectDisk 11 will automatically identify SSD storage and if configured to optimize performance, will perform a Consolidate Free Space pass on the drive. PerfectDisk does not perform this pass automatically.  You must specifically tell PerfectDisk to optimize the drive. PerfectDisk allows you to perform this pass manually or on a scheduled basis. In addition, you can configure PerfectDisk to only optimize the SSD storage if free space fragmentation exceeds a specified threshold.

SSD overview and do I need an SSD defrag -- Part 1
 

                                                   

While still in its infancy, we get more and more inquiries about Solid State Drives (SSDs) and whether or not they need defragging - is there a need for an SSD defrag. Greg Hayes, Raxco Software's manager of technical solutions, has a recently-published short white paper that gives an overview of the technology as well as performance considerations and the issue of SSD defrag. 

I'm going to take the next couple of posts to cover what's in the paper. 

SSDs, when used, replace traditional electro-mechanical parts (i.e. rotating disk platters and read/write heads) with flash memory.  The benefits of SSD storage are:

• Very fast random access times due to elimination of slow electro-mechanical components
• Low read latency times due to elimination of disk seek times
• Consistent read performance because physical location of data doesn't matter (no "fastest" part of the drive as in traditional disk drives)
• File fragmentation has negligible effect due to elimination of electro-mechanical component (seeking).

Due to the nature of the flash memory and how data is currently written, SSD write performance degrades over time.  Unlike a hard disk drive, any write operation to SSD storage requires not one step, but two: an erase followed by the actual write.  

                                            

SSD performance depends on the following factors:

Write Endurance

The number of write cycles to any block of flash is limited.  The maximum number of write cycles (endurance) is dependent on type of flash memory (MLC vs SLC) and varies from 10,000 write cycles in older SSD drives to 1,000,000 write cycles with today's modern SSD drives.

Write Amplification

Write Amplification is native to all NAND flash memory.  Just as with traditional disk drives, with NAND flash memory, data is laid down in blocks.  However, block sizes on an SSD are fixed - meaning even a small 4k chunk of data write can take up a 512k block of space, depending on the NAND flash memory being used. When any portion of the data on the drive is changed, a block must first be marked for deletion in preparation of accommodating the new data (read/modify/write).  The amount of space required for each new write can vary. The write amplification factor on many consumer SSDs is anywhere from 15 to 20. That means for every 1MB of data written to the drive, 15MB to 20MBs of space is actually needed .  For example, a read/modify/write algorithm in an SSD controller will take a block about to be written to, retrieve any data already in it, mark the block for deletion, redistribute the old data, then lay down the new data in the old block.

In the next post, I'll cover wear leveling, over provisioning, TRIM, and how PerfectDisk and defrag relates to SSD technology. 
                                                       
 

                                     

It's not often that PerfectDisk and disk defragmentation software get into an article on a hot topic like Google Voice in publications like Network World and ComputerWorld. But yesterday was such a day. Okay, you have to read the entire article and it's not the focus of the article, but hey, I'll take it (and for a ComputerWorld, Network World, PC World article all about PerfectDisk, see this).

                                              

Mark Gibbs, writing in Network World in an article picked up by ComputerWorld and others, penned Google Voice turned loose and finding duplicated files in an article stating that Google Voice is now available to the public. And not being a Google Voice user right now, I will be soon. After reading Gibbs article, there seem to be many reasons to follow his advice -- "...you should really check it out...."

Besides giving a brief overview of Google Voice, Gibbs turns his focus to duplicate file removal and duplicate file software. It's a key part of a cleaning and streamlining effort he undertakes, writing:

"...what could need cleaning out? The answer: Duplicate files.

On my storage systems I have literally hundreds of projects along with various resources that simply exist for our entertainment (such as iTunes) that I know contain in many cases many duplicate copies of files.

So, in an attempt to streamline my stuff, I decided to try out three de-duplication products..."

I agree wholeheartedly with Mark that duplicate file removal is important and a great way to clean your PC. What Mark didn't mention was that PerfectDisk includes a duplicate file manager for duplicate file removal. However, he does mention that PerfecDisk is handling his disk defragmentation needs on his servers and PCs.

So check out Google Voice, whether or not you need duplicate file software or a defrag utility. And check out Mark Gibbs article in Network World and ComputerWorld here. Mark knows his stuff - he's done just about everything in the networking business, from serving as an executive in various companies to creating companies; and as an author he has written four books and numerous articles about networking and computer technology.

Apparently, he can't be dupped.

                                        
 

                                                         

As another weekend approaches, so does that time when many Exchange administrators think about the need to defrag Exchange database, and if they're smart, some good Exchange defrag software.

Now, Exchange performs, on its own, some basic defragmentation. But here I'm referring to Exchange offline defragmentation. Offline defragmentation and subsequent compaction of your Exchange Server data stores allow the operating system to reclaim disk space occupied by deleted data. How does this happen?

As users delete e-mails, the Exchange Server software frees up the space within the data stores where those e-mails reside, but never returns actual on-disk storage space to the operating system. The resulting data store never shrinks in size, whereas smaller data stores equate with expedient backups and more efficient disk utilization. If an Exchange data store starts to consume increasingly large quantities of disk space, the only way to reclaim those resources is to perform an offline defragmentation and compaction pass.

Now, an Exchange administrator can do this via the ESEUTIL utility, but it's a cumbersome and time-consuming task. There's a lot of manual commands and entering of data that is prone to user error. Which is why we developed PerfectDisk Exchange to automate the process and save Exchange administrators time -- lots of time. PerfectDisk Exchange enables you to automatically shut down an Exchange Server, then copies selected data stores to local or remote volumes, and compacts and optimizes volumes. You can also return data stores to their applicable Exchange directories and restart Exchange Server either through the user interface or via a scheduled event. On Exchange 2000, 2003, 2007 and 2010, selected data stores are dismounted and no services need be stopped. This leaves your mail server available to other data stores it may manage.

A question we often hear is "how much free space is needed to perform an Exchange defrag?" The answer is 110%.

When your data store is being defragmented, a copy is made and defragmented, then copied back to the location of the active information store. In order to create this temporary working copy of the data store, there needs to be sufficient space on your hard drive. The process requires free space equal to 110% of the size of the data store. By default, the boot drive (i.e., the drive containing the WinSystem folder) will be used.

There's a way to defrag Exchange without all the aggravation and without all the time - with the proper Exchange defrag software.
