Diskeeper Corporation will enter spring 2012 as Condusiv Technologies.

Condusiv

Today, Monday March 5, the leader in high performance optimization and maintenance software for technology, people and business has changed its name to Condusiv Technologies. The company ceased operating under the name Diskeeper Corporation as of midnight on March 4, 2012.

“Shortly after being appointed CEO of Diskeeper, in September of 2011, I reviewed the core intellectual property and leadership of the company. I realized that I had inherited a very talented team with deep engineering expertise and a passionate desire to develop thought leading high performance software; innovative products that would have extremely positive measurable impact on our customers’ business, economic recovery and macroeconomic growth,” says Jerry Baldwin.

“We are a very different organization today than we were when the company was founded in 1981. Adopting a new name and brand identity is a logical next step in our growth strategy. This change reflects our team’s passion for developing industry leading solutions and partnerships with customers to bring about positive growth and change.” said Jerry Baldwin, new CEO of Condusiv™. “Condusiv expresses what we have become as an organization as well as what we hope to be — a highly focused dynamic leader that transcends the boundaries of traditional solutions with innovative products that rapidly and dramatically improve productivity in technology, people and business”.

“Condusiv is a word that connotes putting emphasis on possibility and future”, says Baldwin…“just as our company focuses on helping its customers extend operation efficiency and equipment longevity to increase productivity today and for tomorrow.”

“Condusiv is a more modern and dynamic expression of the company’s new marketplace position as a leader providing software optimization and performance solutions that can swiftly help to bridge economic recovery with restored economic growth for customers,” stated Baldwin.

John Lake, Vice President Marketing, Condusiv said, “when developing a new brand name for the company, our team was inspired by ideas of bold growth and inventive thinking. We wanted to connect with the reality that global business is changing faster than ever, and select a name wherein customers understood Condusiv is about advantageously helping them make these changes. Condusiv is derived from the word conducive, meaning contributing to making an experience better. The name perfectly describes the company’s focus on helping customers. Condusiv, in its shortened form and unique spelling, also captures the essence of partners who are incredibly technologically innovative in a fast-paced and demanding world.”

The name change follows 31 years of successful business with Fortune 100 to Fortune 1000 companies, but with a new passionate mission to connect customers and partners, technology and people with the benefits of optimized efficient growth, fast thinking and change.

Lake noted, “the firm welcomed its employees back to work after a company launch event with rebranded offices, signage and stationery. On March 5, we will be launching an aggressive global rebranding campaign that will reinforce our new marketplace positioning and introduce the new brand to our clients, recruits and the public at large”.

Here is what Diskeeper said:

August 17, 2011—Diskeeper Corporation has teamed up with Samsung Electronics Co., Ltd for the global launch of ExpressCache™ intelligent SSD caching technology. Samsung is the first OEM to announce public deployment of ExpressCache, premiering it in their new Series 7 GAMER notebook PC at the World Cyber Games (WCG) in Germany.

“There is a huge, measurable performance boost with ExpressCache technology installed in Samsung’s new Series 7 GAMER notebook PC,” notes Diskeeper EVP for Technology, Mr. Paul Raphael. “While the top gamers will be the first to experience it, anyone with high performance computing needs can benefit from ExpressCache technology implementation. We’re thrilled to have the privilege and opportunity to launch it worldwide with Samsung first.”

ExpressCache intelligent SSD caching technology is licensed to OEMs to provide PC users with significant reduction in boot times and lightning fast launches of application and frequently accessed data files. This software technology coupled with a small Solid State Drive (SSD) and HDD provides the look, feel and responsiveness of pure SSD systems, at a fraction of the cost. By placing it in the Samsung Series 7 GAMER, ExpressCache delivers incredible performance even for the most demanding applications and games:

“With the Series 7 GAMER we have delivered a notebook PC offering the ultimate performance and incredible gaming features,” said Kyuho Uhm, Senior Vice President of the IT Solutions Business at Samsung Electronics. “The market for specialized gaming products is extremely discerning, so it is a challenge to provide a gaming notebook PC that can compete with desktop PCs. Despite all the challenges, we have created a product of the highest standard that appeals directly to gamers’ true passions, which can be met at the turn of a dial to deliver optimum performance for a wide variety of different activities.”

Windows Home Server is great at recovering lost or deleted files from your backed up machines. But what do you do if you haven’t backed up your computer, or the file was on a memory card or flash drive? That’s when Emergency Undelete comes to the rescue.

main-banner

Here is how Diskeeper describes Emergency Undelete:

It only takes one lost file to quickly realize how valuable this software is.

You can be the hero to the friend in need or save yourself big time when you accidentally delete the presentation you are about to give while out of town on business. For just $19.95 you are prepared whenever and wherever you need to recover a file from any PC, thumb drive, external hard drive or camera.

65% of data loss is caused by accidental deletions. Don’t wait until you’ve already lost a file to look for a solution. Just the act of looking for a solution on your PC, could cause the lost file to be overwritten and unrecoverable.

Now you can easily recover files, photos, videos, music and more in seconds. You can even restore files that were deleted from the Windows Recycle Bin. Accidentally deleting a file doesn’t mean it has to be lost forever.

When you delete a file on your PC or other external storage device, it isn’t really deleted; the space the file was using is simply marked as being available for re-use. If nothing has needed that space since the deletion, the data is still there and the file can be recovered using Emergency Undelete.

Emergency Undelete Can Recover:

  • Files: Recover all your files, no matter how you deleted them.
  • Photos: Get your precious one-of-a-kind photos back fast.
  • Videos: Momentous videos are irreplaceable – recover them before they are gone for good.
  • Movies: Your favourite movies are far from gone.
  • Music: Your entire music collection that has taken years to collect – saved in an instant.

We will be reviewing Emergency Undelete very soon, so watch this space.

DK_2010_logo_cmyk-wht

Some brand new features include:

Instant Defrag™

Diskeeper 2011 offers a ground breaking new combination of technology that prevents (IntelliWrite) and immediately eliminates (NEW Instant Defrag) performance-impacting fragmentation so you’ll likely never access slow files ever again. IntelliWrite prevents up to 85% and more, fragmentation from occurring on the initial write. If fragments are not prevented during the initial write, IntelliWrite passes along information about the remaining fragments, in real-time, to the Instant Defrag engines for immediate handling. This exclusive design allows Diskeeper to stay ahead of performance robbing fragmentation on systems that split up data at a high rate. It also minimizes system-resources by eliminating time-consuming whole-volume fragmentation analysis in order to determine what recently written data needs to be defragmented.
The user is informed of the benefits of Instant Defrag in the Dashboard which displays the average time to prevent and handle newly occurring fragments.
IntelliWrite, combined with the new Instant Defrag, provides 100% performance 24×7. With IntelliWrite preventing the vast majority of fragmentation before it can occur, writing files contiguously in the first place, and Instant Defrag immediately eliminating any fragments that sneak by, performance levels are always at peak.

 

Efficient Mode™

Efficient Mode, new in Diskeeper 2011, minimizes the time and resources used by Diskeeper to restore and maintain peak performance and reliability.
Diskeeper reports information about Efficient Mode in the updated Diskeeper user interface. By tracking the I/O (Input/Output) activity on a system Diskeeper 2011 also now estimates the overall I/Os saved (due to removing fragmentation) with time-based data in the updated Diskeeper Dashboard and cumulative statistics in the Diskeeper History section.

The new Efficient Mode is smart enough to know the difference between fragmentation that is a problem and fragmentation that is not a problem. Efficient Mode only addresses problem fragmentation. By eliminating the extra effort to get to a state of 0 total fragments, the resources required to restore peak performance are minimal. Efficient Mode is available in all Diskeeper 2011 editions expect for Home edition.

 

Performance Report

Diskeeper’s new performance report overlays the main User Interface (UI) to provide the user with an instant view of gains they experience with the new Diskeeper 2011. Users will see:
 System Configuration Status
 Read and Write Access Time – % improvement
 How much fragmentation was prevented and eliminated
 Cumulative Number of I/Os Saved

The guys over at Diskeeper have just posted a really good blog post on WHS Vail Storage provisioning.

If you want to know more about storage provisioning in Vail, and how it all works, you really should have a read of the post, which is reproduced below:

As a Gold Partner, the first commercial defragmenter designed for WHS, and even one of the first 8 products to declare support for WHS when Bill Gates first announced it at CES several years back, we’ve been real close with the development team at MS.

The MS team’s insight into the needs and capabilities of defrag has led to significant cooperation as they complete the new Drive Extender. We’ve had many calls over the past months and are very happy to say that many of our suggestions and requests have been accommodated. The functionality that has been added from those meetings will result in well integrated and functional third party software solutions.

Supporting Drive Extender 2.0…

Vail, which is in public beta, has already been generating a great deal of buzz on WHS forums. Drive Extender (DE) is a storage subsystem that extends storage functionality above and beyond what a typical Windows NTFS volume offers. Key purposes of DE are to offer fully automated and easy to use storage. All the complexities associated with fault tolerance solutions like RAID to provide drive reliability, expanding storage over time, and even solving data reliability concerns of commodity drives.

Drive Extender in Windows Home Server today implements drives independently and pools them into a common volume. This pool of storage is then presented as a single volume to the user (i.e. D:\). And, just off the root of this pool (D:\shares) you had all your WHS shared folders; e.g. Users, Photos, Videos, etc…

The user experience of WHS today is already such that you don’t need to care or interact with the volumes, you could even argue that its discouraged.

What is unique in DE 2.0 is that this paradigm has kind of been flip flopped. While it all still looks like a common repository the delineation of storage now begins with those shared folders. So, as an example, let’s take the shared folder “Photos”. In DE 2.0 that folder now becomes a dedicated NTFS volume presented out of the shared storage pool. The folder “Videos” becomes its own NTFS volume, and so on. This design was introduced to support features like real time folder level duplication, etc.. The only minor side effect is that because there are only 26 letters in the English Alphabet, there will be a limitation of the shared folders you can create in this location on WHS. Not a big deal, given the value of the features that this new design offers.

If you’ve read this blog and the comments, you’ll pick up that DE is extending a volume (i.e. a shared folder), in 1 GB chunks, taking those chunks from the total available storage pool.

What you effectively have with Drive Extender, then and now, is storage virtualization. Any time you pool storage and then divvy it up exclusively to requestors (in this case the shared folders that become lettered volumes) you need some form of logic for allocating data from the pool. SAN and virtualization administrators already understand this concept, including related technologies such as Thin Provisioning.

DE 2.0 now adds this to their storage virtualization solution. As you add more data to a shared folder, DE 2.0 will allocate, in 1 GB chunks, more space to the shared folder/volume from the common storage pool. And, should you delete ALL the data in a 1 GB chunk, the 1 GB chunk will dynamically return to the available storage pool to be allocated to any other shared folder that may need the space. DE is well designed to fill up 1 GB chunk before requesting to use more. Very cool stuff!

Here’s a demo of how the provisioning works. Assuming 20GB of space (divided into those 1GB chunks)

You now start to fill up storage adding a little over 4GB of photos and a little over 2GB of music files. That has now pulled eight 1GB chunks from the common pool and these volumes have dynamically expanded to hold up to 5 GB and 3 GB respectively. Keep in mind that files place in the Photos folder will NOT reside on the same 1 GB chunk that contains Music files. In this case, under the DE “covers” they are on completely separate Windows volumes.

And, as those eight 1 GB chunks are provisioned to shared folder volumes, the storage pool shrinks by 8GB.

Now… If you delete all the MP3 music files that reside in one of those 1GB chunks…

DE can return that chunk back to the storage pool for re-provisioning re-use with any other shared folder.

Subsequently shrinking the Music folder/volume to two 1 GB chunks:

However, there are some conditions in which this provisioning technique can use some assistance, and Diskeeper will be helping out (per the request of the WHS/DE team at MS). Should you delete some of the data from 1 GB chunks, but not all of the data within a 1 GB chunk, you can have a lot of 1 GB chunks allocated to a shared folder/volume, but not actually using all of the space it is taking from the common storage pool. Diskeeper will be helping in these cases to group together all the data spread across sparsely filled 1 GB chunks. We’ll effectively be squishing the data together aligning it along 1 GB boundaries. The benefit of this is that some 1 GB chunks may then be freed up and returned to the storage pool to be assigned to your other shared folders.

Here’s a quick graphic to explain the process. Five 1 GB chunks are taken up by the Photos folder/volume. Over time, unwanted photos may be deleted, but the space they were taking up is not made available to any folder other than Photos. In order to make the space (3GB in this example) available for Videos or Music, you would need to move the data out of the sparsely filled chunks. Once done, those now empty 1 GB chunks can be used elsewhere.

Is this an issue you’ll come across? Maybe. If you do, it’ll likely be a bit of time and a lot of file deletions down the road. The Microsoft provisioning design is well suited to most users who mainly add and retain data. Those who do housecleaning or more involved data management can benefit from the upcoming Diskeeper solution – stay tuned.

While we’d like to take credit for this new feature in a future release of Diskeeper HomeServer, it was quite frankly MS directly asking us, as a partner, to add this into our product. Perhaps they’ll add this data squishing into WHS down the road? In the mean time, you can look to Diskeeper to help.

PS: thanks to the Microsoft WHS team for reviewing and approving this blog post.

Excellent work guys – looking forward to seeing the new version of Diskeeper.
