Condusiv launches V-Locity 4, aims to speed up virtual machines

Summary: The company, formerly known as Diskeeper, is aiming to derive 30 percent of its revenue from V-Locity 4.


Condusiv Technologies on Monday launched the latest version of its V-Locity software, which aims to speed up VMware and Microsoft Hyper-V virtual machines without adding new storage hardware.

The company, formerly known as Diskeeper, is aiming to derive 30 percent of its revenue from V-Locity 4. Today, V-Locity accounts for 10 percent of sales.

V-Locity 4 is designed to speed up the read and write process at the service to boost virtual machine performance. Condusiv is claiming a 50 percent improvement on response times. The upshot is that more virtual machines can be crammed onto a server by minimizing bottlenecks.

For Condusiv, V-Locity 4 could position the company well in networked storage environments.

According to the company, the latest V-Locity includes:

  • A new user interface.
  • A technology called IntelliWrite that prevents Windows from breaking files into pieces and then writing them again. 
  • V-Aware, which detects external resource usage from virtual machines.
  • Technology called CogniSAN to optimize VMs.

The base pricing tier for V-Locity 4 is 2-9 cores. The per core price at this level is $269. The minimum configuration would be 2 core with a list price of $538. Most systems would have at least 4 cores and equate to a list price of $1,076.

  • V-Locity 4 or PerfectDisk vSphere/Hyper-V?

    I think that Diskeeper always puts out a decent product. That being said, so does Raxco Software. In the end, it's all about options and for half the cost, PerfectDisk vSphere/Hyper-V should be on your list too. And because it's now part of the PerfectDisk Enterprise Suite, you have the option to license it on an unlimited numbers of machines. Like I said, it's about options but in the end, they both do the job well.
    Richard Moskowitz
    • Just the facts

      Richard, as VP of Sales for Raxco (makers of PerfectDisk), your opinion is highly bias.

      Furthermore, this is not a matter of opinion. Fashion is a matter of opinion, not technology. Here, I don't mind a quick grammar lesson:

      I like apples. I don't like oranges.

      An apple is a type of fruit.

      Got that? Good, let's continue. First I should point out that I don't work for Condusiv, but I am a customer, and have been for the past 18 years. Is my take on this bias? No - I could switch to another software for my VMs anytime without losing my job - unlike you.

      Use software X. Use software Y.

      - V-locity is VMware certified.

      Sample quote from VMware: "For peak performance of Guest OSes running Windows, VMware recommends Best Practice maintenance with V-locity virtual platform optimizer, a VMReady solution."

      - Ten major technology manufacturers (leaders in STORAGE and COMPUTING technologies) license Condusiv's OEM products for optimization of the hardware they manufacture.

      This isn't a secret, I found this information here:

      - With V-locity 4, Condusiv's website states that if the software doesn't make your VMs at least 25% faster, they will give you the software for free

      With that kind of confidence and backed by VMware, the leader in virtualization, there's nothing else to say.
      • Wow, emotional much?

        As a prospective customer of both companies, I think Richard came off the better of this exchange. While it would have been better for him to include his title, he signed with his real name, and his point was valid.

        The whole "grammar lesson" tangent was just ridiculous. He never made the error that you allege. He started off with the words "I think", and everything that followed was qualified as being opinion.

        I am not sure what it was that garnered such a hostile reply on a topic that just isn't worthy of so much hostility. We are talking about disk optimization, not gay marriage or school shootings. The emotion level in your reply, combined with your anonymous sign-off, sure makes me think you could be a Condusiv employee with an axe to grind. That is all speculation though.

        I think it's interesting that you seemed to call Richard out for posting without including his title, but then didn't sign off with your real name. You do realize that if he was trying to conceal his identity, he could have signed it with "Donald Duck", and not given his real name, right? It seems to me that not including his title was probably an oversight, not some nefarious attempt to conceal his identity.

        I am evaluating both products, and could go either way. I would love to see a whitepaper somewhere that compares the performance of the two head-to-head... but it appears that no such document exists, so I am having to do my own testing.

        Regardless of which way I go, I think that fundamentally, the point that Richard made is correct. In discussing disk optimization solutions in a virtualized environment, the much better licensing structure and good feature set of PerfectDisk earn it a place in the conversation.

        In my environment (3 hosts, 72 cores), V-locity 4 has a starting price tag of ~$5k, and max price tag of $18k, compared to PerfectDisk's max price of $1800. At best, V-locity is 3x the cost, and at worst, 10x the cost. V-locity 4 might turn out to be better than PerfectDisk... but enough to justify the cost? Even if PerfectDisk isn't the best solution, all it has to do is be "good enough". It may well be the "better value" for price-conscious shops who don't need the Cadillac. I can buy a lot with the $$ in savings.

        By the way, using the Condusiv website as a source for proving that Condusiv is great isn't exactly awe inspiring. Point me to the independent reviews! Now that's something I'd like to read. And not the OpenLabs document that Condusiv has on their website and promotes in their webinar. In my search for objective data to use in my evaluations, I had a look at OpenLabs website to get a measure for their impartiality... and discovered that their business is to sell the product, not produce an impartial analysis.

        Has any independent company at all done an impartial analysis of either product that I can look at? That is information that I am hungry for.

        • Re: Wow, emotional much?

          Rob, as a fellow customer, I appreciate your comments. Also as a customer, I don't feel like my real name matters. However, when you are VP of Sales for a software company, and don't make it obvious, that just sends the wrong message. But, I'll agree with you and let's just call it oversight.

          I do stand behind my grammar lesson though. I was simply stating the difference between OPINION and FACT. Regarding OpenLab, or is it OpenBench? The information I found on them states as follows "independent test lab
          and provider of third-party validation services". They did their own independent testing using Iometer and the results are pretty impressive, so there's your impartial analysis.

          Anyway, I just get tired of seeing companies promoting products without facts backing them up. I'm not interested in marketing spin, just accurate information and feel that Raxco fails to do this.

          Sam Friedman
          • Thanks

            Sam, thanks for the thoughtful response!

            You are right... it was OpenBench, not OpenLabs. I was working from memory.

            The reason that I discounted the OpenBench paper is because of the OpenBench website. If you look at their website, they are not in the business of presenting the impartial good, bad, and ugly of a product. Instead, their business is to take the benchmark data and present the product in the most favorable light using that data. It's basically sales. While the data itself may be impartial, the way it is presented is not. It's been a while since I read the OpenBench paper on V-locity, but I don't recall that they had a single negative thing to say. That's just not possible. There is a trust issue.

            I think you and I have in common a desire to get past marketing and branding and get to what's real. So far, much of what I see about V-locity sounds really attractive, but I am trying to ascertain what is real.

            For an example, I am thrown by their "CogniSAN" feature. Read the description on their website. How is that feature even possible without configuring the clients with management access to the SAN, or to communicate with all other clients accessing the SAN? Does that communication happen by magic? Configuring that communication was never part of the install process. It ought to be impossible without that configuration step. With no technical description of how they do it, how do I know they are actually doing that? Do I just trust them and take them at their word?

            Same thing with their "V-Aware" feature. During the guest setup, I am never prompted to enter credentials to let the guests access the host to obtain I/O load data. Without authentication, they shouldn't have access to that data. So, how is this feature even possible?

            I learned long ago to question everything. Maybe there are good answers to these questions, but if someone claims to be doing something that ought to be impossible, my instinct is to look for smoke and mirrors, and to consider that I may be just looking at an advertising gimmick.

            I have posed these questions to Condusiv, and if they provide satisfying answers, I'll be glad to post their answers back for the public record. I feel almost like a reporter!

          • Re: Thanks

            Rob, I like your style and have some questions of my own. What method did you use to contact the company?

          • Re: Thanks

            I ask because if you posted on a company forum or message board, I'd be curious to read up on the answers you got before presenting questions of my own.

            If you got in touch via e-mail, yes, please posts the answers you get. Over the years, my sales rep has always been helpful in getting my questions answered, although sometimes I'll do a remote session with one of their engineers as well.

          • Re: Thanks

            I was put into contact with one of their senior engineers by the sales rep, who answered these two questions via email. Since I don't have permission to repost his response, I gave him a link to this discussion and invited him to post a reply.
            Rob Hudson
          • Re: Thanks

            Any further response from the Condusiv engineer?

          • Yes...

            In my opinion, their advertising on this is *very* slippery, if not down right deceptive.

            I was right about the smoke and mirrors.

            There is no feature in V-locity that does what V-Aware advertises that it does, and specifically monitors the virtual host. The client has no awareness of the load on the virtual hosts.

            There is also no feature in V-locity that does what CogniSAN advertises that it does, and specifically monitors the SAN environment. The client has no awareness of the load on the SAN.

            The V-locity client has no actual load data on the VM host or the SAN, despite their advertising to the contrary.

            What they do have is just a simple little mechanism that prevents their automatic defrag service from running when there is I/O latency. They guess that if there is I/O latency, then something somewhere outside of the client might be under load. They have no idea if the load is on the SAN, the VM Host, the network, or where. It's an estimation of what would be the case if they actually had a features that do what CogniSAN or V-Aware claim to do, and it is right enough of the time. But it doesn't do what CogniSAN and V-Aware claim to do.

            I actually like the idea of the I/O latency filter. The I/O latency filter is a nice feature on its own, but not at all what they advertise that they are doing. They advertise much more intelligence than is there. They don't dare advertise what they are actually doing, because then an educated consumer would know that any defrag vendor can easily add an I/O latency throttle to their automatic defragger, and match their V-Aware and CogniSAN "features" in a service pack.

            Other than the I/O latency filter, the only feature that V-locity has that isn't available in other defrag products a fraction of the price is IntelliMemory, which is basically a block level file cache. There are block level file cache tools that can be purchased separately that provide you with much more control over how the cache operates. Why pay a premium to buy a block level file cache utility from a defrag vendor? has SuperCache that is worth looking at.

            In my opinion, Condusiv is leveraging the fact that they are the first to bundle a block level cache with their defrag engine, and are using deceptive advertising combined with vague and misleading technical explanations of how their product works to help create a market where consumers don't really understand what their product does, and just trust that it does it all by "magic". This creates an environment where people will pay much more for their product than the marketplace actually justifies, because people think they are getting more than they are really getting.

            I would absolutely love to see ZDNet commission a whitepaper that compares V-locity 4 performance to PerfectDisk + SuperCache.

            I would bet money that the performance benefit would be equivalent, or even better, because PerfectDisk actually has tools specifically designed to optimize the VM host, and they actually are aware of the VM environment.

            In the meantime, the discovery that Condusiv's advertising is so misleading made my purchase decision for me. I can't trust them.
            Rob Hudson
          • Confused

            Are you talking about the description of these technologies posted on

            I don't see anywhere on this page any statement that says that V-Aware or CogniSAN "specifically monitors" anything, but rather it "detects external resource usage", which is a very different concept. Am I missing something here? Can you point out where you are reading this information about these technologies "specifically monitoring"?

            If anything is misleading, it would be such a whitepaper comparing these two completely different products.

            Anyway, for me at the end of the day, it's all about the performance gains I see. Whether it's monitoring or detecting or doing something completely different, It's about seeing significant performance gains with a minimal footprint on my systems.

            Like yourself, I don't buy into marketing spin, so maybe the best advice I can give you is to try the exercise that I did.

            Basically, with the help of some folks at Condusiv, I ran through a 3-day benchmarking test using V-locity's Benefit Analyzer. Day one was benchmarking WITHOUT V-locity 4, day two was benchmarking WITH V-locity 4 and day three was gathering data.

            The test was run from Tuesday through Thursday on my production servers during a typically workweek, so that each day would measure an equal workload. I have to tell you that the results report was simply unbelievable, but that wasn't even what impressed me most. The bottom line is that my staff actually physically noticed the change in performance on our network, which is something that no report or marketing message ever could do.

            Did you go through this benchmarking test with the Condusiv engineer? If not, I would absolutely recommend it before counting them out.

          • Disappointed

            Sam, I appreciate that you are loyal to Condusiv, and that you are going to give them the benefit of the doubt.

            To be honest, I was rooting for Condusiv at the beginning of this process. I have used Diskeeper on my home machines for years, and began this process with a huge amount of loyalty to Condusiv. I was very excited about their performance claims, and eager to embrace it.

            The number of hoops I had to jump through to get any technical descriptions was a red flag. Then, when I eventually discovered that my perceptions of what their product does based on their marketing were all wrong, I had a visceral emotional reaction. In that moment, I felt lied to. And now, I don't trust them.

            I think I'm a pretty perceptive person. I can tell you that when I initially read the website, and sat through the webinar, that *I* was under the impression that they had two separate kickass features called V-Aware and CogniSAN that monitored the VM and the SAN individually. So, either I am much dumber than the rest of the population, or Condusiv is aware that they are misleading people.

            I have no beef with their technical team. I think their technical side has probably put together a fine product. I like some of the cool things they have done. I like that they have integrated a block level cache. However, I don't trust their marketing team. And if they are being deceptive about one thing, how hard is it to trust anything else they say? How do I trust their benchmarking tool?

            Here are the descriptions of the features straight from the URL you posted above:

            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.

            If you are a prospective user, reading that description for the first time, you assume that the product is doing what exactly? Exactly. You conclude that it has some cool piece of technology that is actively monitoring the virtual host.

            It does *not* do that. It has no way of monitoring the virtual host. It has no knowledge of the load on the virtual platform. It only knows that the client is experiencing I/O latency. It doesn't have a feature that *specifically* monitors the virtual platform. And I say specifically, because they named a specific feature (V-Aware) that they advertise does this specific function.

            By contrast, PerfectDisk *does* have a feature that monitors the virtual host, and detects not only I/O but also CPU and memory utilitization. You can't compare the two features side-by-side, because V-locity doesn't even attempt the same capability.

            From the Condusiv website:

            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.

            Again, a perspective customer reading this description for the first time assumes what exactly? Exactly. That V-locity has a specific feature that specifically monitors the load on the SAN. It is Condusiv that implies this specificity, because they isolated it into its own feature and called it "CogniSAN". You assume a lot of technology and intelligence in play to make this happen. Technology that doesn't exist.

            Because it was so hard for me to track this information down, I have concluded that Condusiv knows *full well* that they are misleading consumers with these feature descriptions. That is why technical details on how these "functions" work are so hard to get. The technical description couldn't be found on their website, and even the salesperson didn't have them. Neither were they in the webinar. I had to go to a high level engineer to find this out.

            Taking a rational step back... The I/O latency throttle is a pretty cool feature that nobody else has. Why not just market that feature honestly?

            If they had just one feature that was called "LoadAware" or something, that matched up to the one capability that they have, and they took time to educate users about its benefits and how it works, then I would have no beef. I actually think it's a pretty nifty feature. They would be being honest. I would might even be a V-locity customer right now.

            I had planned to stage a performance test on several of my VM's around the holidays, but then cancelled the test after I talked to the Condusiv engineer.

            I don't expect to change your mind, Sam. It's all good.

            The only thing that might change my mind is if Condusiv takes steps to clarify their marketing on V-Aware and CogniSAN so that people don't feel misled. Take a step to show that they are willing to pull back the curtain and present their product honestly.

            I doubt they are going to do that for this one little customer, when they benefit so much from those misperceptions. Most prospective customers won't ever dig as deep as I did, and won't ever know that their perceptions of how the product works are wrong until well after the sale.
            Rob Hudson
          • Misunderstood

            I know don't Rob, to me it seems like you read the word "detects" and you define it as "monitors".

            As you said, V-locity DOES have two separate (kickass) features called V-Aware and CogniSAN:

            1. CogniSAN specifically *detects* the load on the SAN - not specifically *monitors* it.

            2. V-Aware specifically *detects* resource usage from other virtual machines - not specifically *monitors* it.

            I don't doubt that you're a perceptive person, but what confuses me is that you feel mislead. The website says "detects" and you assume "monitors" - as a prospective user at first glance, I would think you would assume that the technology detects external resource usage somehow but not monitors it. That’s what the website says, isn’t it? I feel like there’s only so much that can be written on a website before you just need to pick up the phone or send an e-mail to learn more.

            Like I keep saying, I have little if any confidence in marketing teams and don’t buy into marketing spin. I’m a hands-on guy that needs to see for myself what a product can do and measure benefits. I know I’m a long time Condusiv customer, but this is the methodology I use for my purchases from any company.

      • Looks Like I Struck a Nerve... Not My Intention

        To your point about me not posting that I work for Raxco as the VP of Sales, you are 100% right and thank you for pointing that oversight out. You seem pretty emotional about Condusiv and i'm sure they are grateful to have you as a spokesman. As you know, real world customers are a company's greatest asset and after 30 years in the business, Raxco wouldn't be where we are today without ours as well.

        From a competitive perspective, I still stand by what I said. Both Raxco and Condusiv put out great products. But while marketing is what helps get customers in the door, what matters most is the quality of the software once it gets into a customer's hands and the company that stands behind it. For the record, I like oranges but I don't like apples and I know this because I've tried them both. My point is that at the end of the day, both Condusiv's and Raxco's customers are pretty smart and technically competent people and that's why we both offer free evaluations.

        So I will leave it up to you if you want to label this comment as fact or opinion but the point I tried to make last week was consider your options and make the best choice.

    Richard last time I checked the company is now Condusiv.
    2nd, Perfect disc is a light version of anything V-locity 4 does.
