New! Diskeeper 16 Guarantees “Faster than New” Performance for Physical Servers and PCs

by Brian Morin 26. September 2016 09:56

The world’s most popular defragmentation software for physical servers and PCs makes “defrag” a thing of the past and delivers “faster than new” performance by dynamically caching hot reads with idle DRAM.  As a result, Diskeeper® 16 guarantees to solve the toughest application performance issues on physical servers like MS-SQL and guarantees to fix sluggish PCs with faster than new performance or your money back for 90 days – no questions asked.

The market is still catching up to the fact that Diskeeper’s newest patented engine no longer “defrags” but rather proactively eliminates fragmentation with large, sequential writes from Windows to underlying HDDs, SSDs, and SAN storage systems. This eliminates the “death by a thousand cuts” scenario of small, tiny writes and reads that inflates I/Os per second, robs throughput, and shortens the lifespan of HDDs and SSDs alike. However, the biggest new announcement has to do with the addition of DRAM caching – putting idle DRAM to good use by serving hot reads without memory contention or resource starvation.

“Diskeeper 16 with DRAM caching served over 50% of my reads from DRAM and eliminated over 30% of write traffic by preventing fragmentation. Now everything is more responsive!” - David Bruce, Managing Partner, David Bruce & Associates

“Diskeeper 16 with DRAM caching doubled our throughput, so we could backup in half the time.  Our Dell Rapid Recovery backup server is running smoother than ever.” - Curtis Jackson, Network Admin, School City of Hammond

“WOW! Watch it go! I have 44GB of memory in the physical server and Diskeeper is using around 20GB of it to cache!! I can’t imagine having a server without it! Diskeeper 16 is a vastly improved version of Diskeeper!” - Andy Vabulas, Vabulas Enterprises

“Our Symantec app running on a physical server has been notoriously slow for as long as I can remember, but since adding Diskeeper 16 it has improved significantly.” Josh Currier, Network Infrastructure Manager, Munters Corporation

 “With Diskeeper 16 I can tell my workstation is more responsive with no lag or any type of hesitation. Truly SMART Technology.” - William Krasulak, Systems/Network Admin, Nacci Printing, Inc.

“Our most I/O intensive applications on physical servers needed some help, so we installed Diskeeper 16 with DRAM caching and were amazed by the performance boost!” - Victor Grandmaiter, IT Director, Fort Bend Central Appraisal District

“Diskeeper eliminated 32% of my write traffic by preventing fragmentation and cached 64% of my read traffic within idle memory. This saved my workstation over 20 hours in I/O time after 24 days of testing!” - Lou Goodreau, IT Manager, New England Fishery

“Installed Diskeeper 16 on our worst performing physical servers running ERP with a SQL database and saw an immediate 50% boost!" - Hamid Bouhassoune, Systems Engineer, Global Skincare Company

A top New York clothing brand tried Diskeeper 16 with DRAM caching on their physical servers and saw backup times with Veeam and Backup Exec drop by more than half!

Before Diskeeper Install:

8/7, 10GB, 14MB/s, 1:38

8/8, 11 GB, 13MB/s, 1:54

After Diskeeper Install:

          8/12, 13GB, 21MB/s, 1:30

        8/13, 14GB, 30MB/s, 0:58

        8/14, 13GB, 33MB/s, 0:55

        8/15, 11GB, 36MB/s, 0:44

        8/19, 17GB, 30MB/s, 1:06

 

A Large Illinois Non-Profit tested Diskeeper 16 with DRAM caching on Windows 2012R2 physical servers running CRM and accounting software with a MS-SQL backend. Note – these improvements were almost exclusively from Diskeeper 16’s write optimization engine since idle memory was not available to initiate the new caching engine.

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.
