What Condusiv’s Diskeeper Does for Me

by Tim Warner, Microsoft Cloud & Datacenter MVP 4. November 2019 05:36

I'm a person who uses what he has. For example, my friend Roger purchased a fancy new keyboard, but only uses it on "special occasions" because he wants to keep the hardware in pristine condition. That isn't me--my stuff wears out because I rely on it and use it continuously.

To this point, the storage on my Windows 10 workstation computer takes a heavy beating because I read and write data to my hard drives every single day. I have quite an assortment of fixed drives on this machine:

·         mechanical hard disk drive (HDD)

·         "no moving parts" solid state drive (SSD)

·         hybrid SSD/HDD drive

Today I'd like to share with you some ways that Condusiv’s Diskeeper helps me stay productive. Trust me--I'm no salesperson. Condusiv isn't paying me to write this article. My goal is to share my experience with you so you have something to think about in terms of disk optimization options for your server and workstation storage.

Diskeeper® or SSDKeeper®?

I've used Diskeeper on my servers and workstations since 2000. How time flies! A few years ago it confused me when Condusiv released SSDkeeper, their SSD optimization tool that works by optimizing your data as its written to disk.

Specifically, my confusion lay in the fact you can't have Diskeeper and SSDkeeper installed on the same machine simultaneously. As you saw, I almost always have a mixture of HDD and SSD drives. What am I losing by installing either Diskeeper or SSDkeeper, but not both?

You lose nothing because Diskeeper and SSDkeeper share most of the same features. Diskeeper like SSDkeeper can optimize solid-state disks using IntelliMemory Caching and IntelliWrite, and SSDkeeper like Diskeeper can optimize magnetic disks using Instant Defrag. Both products can automatically determine the storage type and apply the optimal technology.

Thus, your decision of whether to purchase Diskeeper or SSDkeeper is based on which technology the majority of your disks use, either HDD or SSD.

Allow me to explain what those three product features mean in practice:

·         IntelliMemory®: Uses unallocated system random access memory (RAM) for disk read caching

·         IntelliWrite®: Prevents fragmentation in the first place by writing data sequentially to your hard drive as its

created

·         Instant Defrag™: Uses a Windows service to perform "just in time" disk defragmentation

In Diskeeper, click Settings > System > Basic to verify you're taking advantage of these features. I show you the interface in Figure 1.

 

Figure 1. Diskeeper settings.

What about external drives?

In Condusiv's Top FAQs document you'll note that Diskeeper no longer supports external drives. Their justification for this decision is that their customers generally do not use external USB drives for high performance, input/output (I/O) intensive applications.

If you want to run optimization on external drives, you can do that graphically with the Optimize Drives Windows 10 utility, or you can run defrag.exe from an elevated command prompt.

For example, here I am running a fragmentation analysis on my H: volume, an external SATA HDD:

PS C:\users\tim> defrag H: /A

Microsoft Drive Optimizer

Copyright (c) Microsoft Corp.

Invoking analysis on TWARNER1 (H:)...

The operation completed successfully.

Post Defragmentation Report:

         Volume Information:

                Volume size                 = 1.81 TB

                Free space                  = 1.44 TB

                Total fragmented space      = 0%

                Largest free space size     = 1.43 TB

         Note: File fragments larger than 64MB are not included in the fragmentation statistics.

         You do not need to defragment this volume.

PS C:\users\tim>              

Let's look at the numbers!

All Condusiv products make it simple to perform benchmark analyses and run progress reports, and Diskeeper is no exception to this rule. Look at Figure 2--since I rebuilt my Windows 10 workstation and installed Diskeeper in July 2018, I've saved over 20 days of storage I/O time!

Figure 2. Diskeeper dashboard.

Those impressive I/O numbers don't strain credulity when you remember that Diskeeper aggregates I/O values across all my fixed drives, not only one. This time saving is the chief benefit Diskeeper gives me as a working IT professional. The tool gives me back seconds that otherwise I'd spend waiting on disk operations to complete; I then can use that time for productive work instead.

Even more to the point, Diskeeper does this work for me in the background, without my having to remember to run or even schedule defragmentation and optimization jobs. I'm a huge fan of Diskeeper, and I hope you will be.

Improve Performance Without Getting Stuck with Unnecessary and Expensive Hardware

by Marissa Newman 14. August 2019 04:15

We recently completed a case study with a top construction company who deployed V-locity® I/O reduction software to improve speed on Citrix and SQL applications and avoided unnecessary hardware costs.

Performance on Teichert’s Citrix and SQL servers that were running critical applications was beginning to suffer due to the growth of data, increased number of users, and infrastructure virtualization. When user complaints about the slowness of the live-order entry system, queries taking too long, and poor system performance in general were at a high, Steve Lomax, Teichert’s Senior Windows Systems Administrator, began to look at various solutions to optimize their infrastructure.

Having already been a Diskeeper customer, the company decided to evaluate Condusiv’s V-locity® I/O reduction software and were pleased to find that they no longer needed to implement any of the other solutions they were looking at to optimize performance. Steve explained, “We were surprised to learn that Condusiv had advanced their software to such a degree that they were now proactively optimizing writes in-line, cutting out a ton of write I/O that was previously hammering our SAN. We upgraded from a NetApp tiered storage solution…to a hybrid-flash Tintri T850 and experienced the same results from V-locity regardless of the brand or type of storage we had underlying our data center.”

The company saw major improvement across the board and particularly on their Citrix and SQL servers. On their 30 busiest servers, V-locity had prevented 41% of write I/O traffic from occurring and 50% of read I/O traffic from storage due to DRAM read caching.

Deploying V-locity to their virtual infrastructure eliminated the need to spend money on additional hardware and other 3rd party performance solutions. Steve said, “We were looking at other solutions that could give us a performance boost…[but] were able to skip all that because V-locity solved it with a simple install right into the VM and that’s it. You’re done. I would recommend V-locity to anyone that doesn’t want to be stuck with unnecessary hardware costs and needs a solution to add an extra layer of enhanced performance.”

Steve concluded by describing the positive impacts brought on by V-locity’s performance gains. “We’ve seen at least a 50-60% drop in performance-related issues…General frustration is gone, users are more productive and efficient, customers don’t have to wait long periods of time to process orders, and the IT department is freed up to focus on more important initiatives relating to the company’s mission and core values.”

Overcoming the I/O Blender Effect with V-locity

by Rick Cadruvi, Chief Architect 5. August 2019 05:23

You’ve decided that you want to try out V-locity® software – kick the tires so to speak.  You’ll just load it on one of your Virtual Machines and see how it goes.  What kind of benefit will you see?

It is true that V-locity will likely provide significant benefit on that one VM.  It may even be extraordinary.  But loading V-locity on just one VM on a host with sometimes dozens of VMs won’t give you the biggest bang for your buck. V-locity includes many technologies that address storage performance issues in an extremely intelligent manner.  Part of the underlying design is to learn about the specific loads your system has and intelligently adapt to each specific environment presented to it.   That’s why we created a product especially for Virtual environments in the first place. 

The beauty of V-locity is its ability to deal with something called the I/O Blender Effect.  This is the dark side of virtualized systems.  When there are multiple VMs on a host, or multiple hosts with VMs that use the same back-end storage system (e.g., a SAN) a “blender” effect occurs when all these VMs are sending I/O requests up and down the stack.  As you can guess, it can create huge performance bottlenecks. In fact, perhaps the most significant issue that virtualized environments face is the fact that there are MANY performance chokepoints in the ecosystem, especially the storage subsystem.  These chokepoints are robbing 30-50% of your throughput.  That’s what V-locity can recover.

Look at it this way.  VM “A” may have different resource requirements than VM “B” and so on.  Besides performing different tasks with different workloads, they may have different peak usage periods.  What happens when those peaks overlap?  Worse yet, what happens if several of your VMs have very similar resource requirements and workloads that constantly overlap? 

 

The answer is that the I/O Blender Effect takes over and now VM “A” is competing directly with VM “B” and VM “C” and so on.  The blender pours all those resource desires into a funnel, creating bottlenecks with unpredictable performance results.  What is predictable is that performance will suffer, and likely a LOT.

Enter V-locity.  V-locity was designed from the ground up to intelligently deal with these core issues.  The guiding question in front of us as it was being designed and engineered, was:

Given your workload and resources, how can V-locity help you overcome the I/O Blender Effect?

By making sure that V-locity will adapt to your specific workload and having studied what kinds of I/Os amplify the I/O Blender Effect, we were able to add intelligence to specifically go after those I/Os.  We take a global view.  We aren’t limited to a specific application or workload.  While we do have technologies that shine under certain workloads, such as transactional SQL applications, our goal is to optimize the entire ecosystem.  That’s the only way to overcome the I/O Blender Effect.

So, while we can indeed give you great gains on a single VM, V-locity truly gets to shine and show off its purpose when it can intelligently deal with the chokepoints that create the I/O Blender Effect.  That means you should add V-locity to ALL your VMs.  With our no-reboot installation and a V-locity Management Console, it’s fast and easy to cover and manage your environment.

And yes, this same I/O Blender effect can occur in your physical environment with multiple physical systems all accessing different LUNs on the same SAN. Our Diskeeper® software is the answer here.

Go ahead and try V-locity on the VMs that are in the most competition for resources and you’ll be amazed at the benefits.  The chokepoints aren’t obvious or right in front of your face, but they are real and V-locity is the answer.  After that, just add V-locity to all your VMs, then sit back and see how smart you were to so easily improve throughput across your eco-system.

For Larger V-locity Deployments: Getting Up and Running Using V-locity Management Console (VMC)

by Spencer Allingham 18. June 2019 05:32

V-locity® I/O Reduction software is designed to solve and prevent application performance degradation at the source, relieving stress and frustration from user complaints and reliability issues. V-locity eliminates the two big I/O inefficiencies in a virtual environment that generates a minimum of 30-40% I/O traffic chewing up storage IOPS and slowing down your system. Installing V-locity 7 is a quick, easy and effective fix, no reboot required. The first step to improving your server performance is downloading V-locity and starting your Proof of Concept.

 

Here are some helpful tips that will set you up to get the very best results

1. Login to your account to access your V-locity software OR download a free 30-day trial of the software.

2. Make sure you are using Windows Server 2008 R2 or later.

3. Ensure there is at least 4 GB of Available Physical Memory on each machine when checking MSINFO32.EXE (System Information Report) at a peak load time. Note: It is necessary to limit the amount of memory that certain applications can take in order to leave at least 4 GB of memory free. Examples are SQL server, Exchange and Oracle on Windows.

4. Plan to install V-locity on as many Windows machines that share the same storage as possible. If V-locity is only installed onto a small number of machines, you will only be optimizing a small percentage of the overall storage I/O traffic, which is likely to limit the results.

5. IMPORTANT: If using V-locity in a firewalled environment, make sure the correct ports are open. The following ports need to be open for incoming and outgoing TCP packets between the V-locity Management Console and the other machines running V-locity: 135, 137, 139, 443, 445, 5985, 13568-13572, 3102

6. Set aside a dedicated VM for the V-Locity Management Console (VMC). This should be running at least Windows Server 2008 R2 and have Internet Explorer 9 or later installed, or Chrome or Firefox.

Undelete Saves Your Bacon, An In-depth Video Series

by Spencer Allingham 13. May 2019 03:43

Undelete® is a lot more than those simple file recovery utilities that just search through free space on Windows machines looking for recoverable data. Undelete does so much more; protecting files in network shared folders and capturing versions of any number of file types.

If you've ever had to rely on restoring from backup or a snapshots to get a deleted file back, watch now to find out how Undelete makes the recovery faster and more convenient on workstations, laptops and Windows servers.

Undelete, the world’s #1 file recovery software, as a first line of defense in your disaster recovery strategy can save your bacon!

“Undelete saved my bacon.” — Ken C, Cleveland State University

Why are some deleted files not in the Windows Recycle Bin?

Were you aware that the Windows Recycle Bin falls short of capturing all file deletions?

Whilst the Recycle Bin is very quick and convenient, it doesn’t capture:

· Files deleted from the Command Prompt

· Files deleted from within some applications

· Files deleted by network users from a Shared Folder

Undelete from Condusiv Technologies can capture ALL deletions, regardless of how they occur.

“It saved our bacon when a file on my system was accidentally deleted from another workstation. That recovery saved hours of work and sold us on the usefulness of the product.”

“Our entire commissions database was saved by the Undelete program. Very happy about that. We would have lost a week of commissions (over 2000 records easily). We were very grateful that we had your product." Frank B, Technical Manager, World Travel, Inc.

Watch this video for a demonstration of why the Recycle Bin falls short and how the Undelete software can pick up the slack and truly become the first line of defense in your disaster recovery strategy. 

What is Undelete File Versioning?

Have you ever accidentally overwritten a Microsoft Word document, spreadsheet or some other file?

Would it be helpful to have several versions of the same file available for recovery in the Windows Recycle Bin? Sorry, but the Recycle Bin can’t do that.

However, the Undelete Recovery Bin can!

“I'm glad I found yours -- it works very well, and the recovery really saved my bacon!” — John

Watch this video to see a demonstration of how capturing several versions of the same file when they get overwritten can really help save time as well as data.

Searching the Undelete Recovery Bin

Recover deleted files quickly and conveniently with Undelete’s easy search functions.

Even if you only know part of the file name, or aren’t sure what folder it was deleted from, see in this video how easy it is to find and recover the file that you need.

“I would recommend undelete as it has saved my bacon a couple of times when I was able to recover something that I deleted by accident.” — Joseph

Inclusion and Exclusion lists in Undelete

Find out how to use Inclusion and Exclusion Lists in the Undelete software to only capture those files that you really might want to recover and exclude all of those files that you don’t really care about.

Have you ever needed to get a file back that was deleted during a Windows Update? Probably not, so why have those files take up space in your Recovery Bin?

“It saved my bacon a few times.” — Jason

Watch this to see how configurable the Undelete Recovery Bin is.

Emergency Undelete Software

See a demonstration showing how easy it is to recover deleted files, even BEFORE you install the Undelete software from Condusiv Technologies.

Prevent that awful moment of extreme realization when you delete a file that isn’t backed up.

Oh! And if you’ve found this page because you need to recover a file right now, click here to get the free 30-day trialware of Undelete. We hope this helps you out of the jam!

“It has saved my bacon a couple of times when I was able to recover something that I deleted by accident.”

How to safely delete files before recycling your computer with Undelete

Want to get a new computer, but worry what would happen to your personal data if you recycled your old one, or sold it?

Watch now to see how to securely wipe your files from your computer’s hard drives with SecureDelete®, which is included in the Undelete software from Condusiv Technologies, before recycling your old computer, selling it, or passing it on to a friend.
