Four Reasons to Migrate from Diskeeper Server to V-locity Server

by Robert Woolery 30. July 2013 08:19

Still on Diskeeper Server? Here’s four reasons to consider migrating to V-locity Server: 

1. High performance. Whereas Diskeeper® Server, highlighted by IntelliWrite® technology, keeps Windows servers running like new, V-locity® Server goes a step beyond split I/O elimination with the inclusion of a server-side caching engine (IntelliMemory) for performance boosts of 50% or more. With frequently-accessed data dynamically cached within available server resources, hot data no longer trudges the full distance from server to storage and back, consuming unnecessary bandwidth.

With IntelliWrite preventing split I/Os on write requests, and IntelliMemory caching active data on reads, this holistic approach to I/O optimization accelerates the entire IT infrastructure since unnecessary I/O traffic is now eliminated before it is pushed through server, network and storage. 
 

2. Network storage. Whereas Diskeeper Server is ideal for local server storage or direct-attached storage (DAS), V-locity Server is designed for network storage (SAN/NAS) since all I/O optimization occurs at the Windows OS layer, leaving the storage device untouched. With IntelliWrite, V-locity Server proactively eliminates split I/Os as close to the application as possible, and by caching active data within available server memory, IntelliMemory eliminates even more unnecessary I/O—preventing I/O traffic from traveling the full distance to storage and back. Since the storage subsystem is now processing considerably less I/O, bottlenecks are eliminated and more bandwidth is available. 

3. Solid-state storage. Already running solid-state in your storage arrays or server PCI-E? V-locity sits at the top of the technology stack at the Windows OS layer so the entire infrastructure—regardless of vendor—reaps the benefit of I/O optimization downstream. V-locity is proactive—meaning it prevents the surplus of unnecessary I/O from ever being created in the first place. This way, your SSD or HDD media isn’t dealing with the I/O mess after it has already wreaked havoc on your environment.

4. Benefit analysis. Unlike Diskeeper, V-locity comes with an embedded performance benchmark that allows users to see the before/after benefit of V-locity in their real-world environment and share the outcome with stakeholders prior to any kind of purchase commitment. This single-page report provides metrics like workload comparison, I/Os per second, latency, and more. 

For high-performance in environments that leverage advanced storage technologies, V-locity Server is the best bet to maximize your existing hardware investment and eliminate performance bottlenecks overnight.

A Blog About Bloggers Who Blog About Us

by Jerry Baldwin 7. February 2013 09:49

On contemplating the impact of his calculating engine, the world’s first computer, Charles Babbage wrote “In turning from the smaller instruments in frequent use to the larger and more important machines, the economy arising from the increase of velocity becomes more striking.” He said that in 1832.

I mention this because the idea holds true today—the bigness of everything, the immediacy of everything, the pace of everything—the greater the increase from one state to another, the more striking the difference. And that’s exactly why—when we put V-locity 4 trialware into the hands of virtualization wizards to test in their lairs—we want them to really, really put it through the wringer. The heavier the workload, the greater the application demand, the more striking the results.

Recently two virtualization pros got their hands on the V-locity 4 30-day trial, set up rigorous testing, and blogged the entire experience:

NEW V-locity 4 VM Accelerator Improves VM Performance by up to 50%

by Jeff Medina 10. December 2012 10:00

Today we are very excited to announce the release of V-locity 4 VM Accelerator. With this latest release, V-locity increases VM and application performance by up to 50% and does so without any additional storage hardware.

Let’s face it - in today’s world of virtual environments, we generate a tremendous amount of data and it’s only the beginning. In fact, findings included in a recent study by IDC titled “Extracting Value from Chaos” predict that in the next ten years we will create 50 times more information and 75 times more files.

The impact of this data explosion on server virtualization can often lead to I/O bottlenecks. This is because a physical server running multiple virtual machines (VMs) must often carry out far more I/O operations than one server running a single workload, and typical virtualization environments emulate I/O devices that run less efficiently than native I/O devices.

In essence, virtualization acts like a funnel, combining and mixing many disparate I/O streams, sending out to the disk what becomes a very random I/O pattern. To make matters worse, the more VMs are added, the more the issue is compounded as more I/O is "randomized." All of this has a very negative affect on storage performance, and renders time-honored techniques such as read-ahead buffers and caching algorithms far less effective than in conventional physical environments.

Storage I/O is the most critical issue in a virtualized environment, and can cause organizations to spend a great deal on storage, purchasing more and more disk spindles, but often using only a fraction of their capacity because of performance issues. The outcome is that, due to issues relating to performance bottlenecks in the storage infrastructure, some applications are deemed unable to be virtualized; however, a properly tuned storage environment might have accommodated those applications. So what’s the alternative? The answer is V-locity 4 VM Accelerator. 

V-locity 4 VM Accelerator provides:

  • Increased application performance up to 50%
  • Up to 50% faster access to frequently accessed files
  • Faster I/O performance without the cost of additional storage hardware
  • Increased VM density per physical server up to 50%
  • Extended hardware lifespan by eliminating unnecessary I/Os
  • Automatic and real-time operation for true “Set It and Forget It®” management 

What makes V-locity 4 so effective is its powerful toolkit of proactive technologies, including IntelliWrite,® V-Aware,® CogniSAN,® InvisiTasking® and the new IntelliMemory® RAM caching technology.

New! IntelliMemory™ Caching Technology
IntelliMemory intelligent caching technology boosts active data, improving I/O response time up to 50% or more while also eliminating unnecessary I/O operations from getting into the network or storage.

Improved! IntelliWrite® Technology
IntelliWrite automatically prevents the operating system from breaking files into pieces and writing those pieces in a performance penalized manner. This proactive approach improves performance up to 50% or more while preventing any negative impact to snapshots replication, data deduplication or thin provisioning growth. As this proactive approach happens at the server level, the network and shared storage simply has less I/O operations to transfer and process.

New! Performance Benefit Analyzer
The Performance Benefits Analyzer helps document the performance benefits of V-locity. The benefit analyzer looks at your current system performance, then compares these results to those after using V-locity to provide a detailed report showing specific improvements and benefits to your system.

V-Aware® Technology
V-Aware detects external resource usage from other virtual machines on the virtual platform and eliminates resource contention that might slow performance.

CogniSAN® Technology
CogniSAN detects external resource usage within a shared storage system, such as a SAN, and allows for transparent optimization by not competing for resources utilized by other VMs over the same storage infrastructure. And it does this without intruding in any way into SAN-layer operations.

InvisiTasking® Technology
InvisiTaksing allows all the V-locity 4 "background" operations within the VM to run with zero resource impact on current production.

Set It and Forget It®
Automatic and real-time operation.

Windows 8 Released

by Alex Klein 29. October 2012 05:35

Microsoft officially released the next version of Windows last week – Windows 8. While this new release contains various technological advancements, issues with I/O performance and its effect on Windows systems still remains.

Every I/O operation that occurs takes a measureable amount of time. There’s no such thing as an instant I/O request, and simply put, the more I/Os necessary, the longer it will take for Windows to complete a particular task. 

To understand why this is still an issue on Windows 8 and even Windows Server 2012, let’s explore a bit deeper. When data is written within the Windows file system, it is naturally written in a non-optimized way. Thus when an application requests the data, the initial I/O request generally gets broken down and  splits into many additional requests (called split I/Os), and thus increases the time necessary to retrieve the information. So, as this activity naturally occurs on a daily basis, it takes more and more I/O requests and increasingly impacts the performance of your servers and workstations. 

The Windows built-in optimization tool, which is set to run on a weekly basis, attempts to handle the mounting I/O traffic, but that’s after you’ve already experienced the performance impact in the first place. For example, say I’m working on a project on a Tuesday afternoon – how is running the built-in optimization utility on Wednesday going to address this concern?

Proactive Windows I/O acceleration is the key to successful operations and improved response time to users and this is why Condusiv Technologies created our Diskeeper product. Diskeeper’s InvisiTasking and IntelliWrite technologies helps prevent the vast majority of extra I/O requests from occurring and does so without taking any additional resources from the system or other applications. This ensures that you get the least number of I/Os to go to the storage and allows your applications to run that much faster. 

 
In fact, recent independent testing by openBench labs shows up to 98% few I/O requests, server throughput increased by 130% and data throughput up to 5X faster on workstations. You can read more of this report here.

The Next Generation of Real-time Protection and Instant Recovery Software

by Alex Klein 4. September 2012 04:00

Today we announce the worldwide release of Undelete 10 – our real-time data protection and instant data recovery product. With just a touch of a button, Undelete instantly recovers files from Windows servers and workstations – even files that were deleted before Undelete was installed.

Enterprise IT and data have grown immensely since Condusiv first introduced Undelete over 14 years ago. Regardless of the Windows OS you’re running, whether it be a physical or virtual environment – Undelete is the one piece of software your company can’t afford to be without and can truly turn your IT department into a team of heroes.

“I came by Undelete when we had a user delete a whole department worth of files”, says Eric Tremelling, who’s the IT Manager at The Legal Aid Society of Palm Beach County. “It did recover all the files for the whole department.  I was so impressed that I purchased the Undelete Server edition to avoid future problems.  In my opinion, Undelete is one of the best programs we have and saves me lots of potential headaches.” 

“We use a backup system that does nightly backups to tape.  If something is deleted from the file server by mistake I have to go back to the tapes then pull the correct tape then run a restore on the file, provided there was no corruption or problems with the backup tape.  Another issue was that the deleted file could be gone before anyone noticed it was missing and I may not still have a backup that old to recover from.  Furthermore, if the file was created during the day before the backup runs at night, it would be gone because it never got backed up yet. The software has gotten us out of many jams”

 

Have an Undelete story to share? Leave a comment below – we’d love to hear from you!

Undelete 10 features

  • New One-button Search for Recent Files, which allows the user to locate a file deleted within a 24-hour period or one week period with one click.
     
  • New Search Wizard, a single pane view that provides fast and easy way to find a lost file.
     
  • New Dynamic User Interface for ease of use, quality of experience.
     
  • Undelete 10 Server - Protects server files including those deleted by network clients from a centralized management console.
     
  • Undelete 10 Desktop Client – Allows connected laptops, workstations and VMs to recover their own files from remote Undelete 10 Server recovery bins.
     
  • Undelete 10 Professional – Protects locally stored files and allows files to be recovered from remote Undelete Server recovery bins.
     
  • Undelete 10 Home – Provides comprehensive protection of locally stored files.

When a file is deleted, it is automatically captured and stored in the Undelete Recovery Bin. Undelete 10 captures all the files the Windows Recycle Bin misses, such as those deleted from shared network folders, deleted from commonly used applications, deleted by the Windows command prompt, or replaced when newer versions of a file are saved. Also, if a file is modified several times between a backup or shadow copy, it will not be saved. With Undelete, these file versions will be saved and are recoverable.

The Server, Professional and Client editions of Undelete let you see the contents of Recovery Bins on remote computers like file servers, allowing IT or users to recover their deleted files in seconds anywhere across the network with a single click of a button. It’s no longer necessary to spend hours searching backup tapes or Windows Shadow copies when a user accidentally deletes a file from the server.

Undelete can also restore files previously purged from the Recycle Bin or the Undelete Recovery Bin – even if they were deleted before Undelete was installed

Condusiv Undelete 10 “Set it and Forget It”® file recovery system runs on all Windows platforms, including those on VMware and Microsoft Hyper-V environments. Undelete 10 also supports Exchange, SQL, or SharePoint. 

Undelete 10 Server edition supports Windows Server 2008/2008 R2, Windows Server 2003,  Windows XP, Windows Vista, and Windows 7.

Undelete 10 Client, Professional and Home Editions support Windows XP, Windows Vista, and Windows 7.

In compliance with corporate governance or governmental regulatory requirements for secure data deletion, Undelete provides an electronic data shedder: SecureDelete® 2.0. Using a bit pattern specified by the National Security Agency (NSA) for the Department of Defense, SecureDelete not only deletes a file but overwrites the disk space the file previously occupied making it virtually impossible for anyone to access.
