Condusiv’s V-locity Technology Was Recently Certified as Citrix Ready

by Dawn Richcreek 11. September 2019 09:51

 

We are proud to announce that Condusiv’s V-locity® I/O reduction software has been certified as Citrix Ready®. The Citrix Ready program helps customers identify third-party solutions that enhance virtualization, networking and cloud computing solutions from Citrix Systems, Inc. V-locity, our innovative and dynamic alternative to costly hardware overhauls, has completed a rigorous verification process to ensure compatibility with Citrix solutions, providing confidence in joint solution efficiency and value. The Citrix Ready program makes it easy for customers to identify complementary products and results-driven solutions that can enhance Citrix environments and increase productivity.

 

 

 

Verified Performance Improvements of 50 Percent or More

To obtain the Citrix Ready certification, we ran IOMeter benchmark tests—an industry standard tool for testing I/O performance—on a Windows 10 system powered by Citrix’s XenDesktop virtual desktop access (VDA).  

The IOMeter benchmark utility was set up to run 5 different tests with variations in the following parameters:

 •  Different read/write size packets (512b to 64kb)
 •  Different read/write ratios, i.e. 50% read/50% writes, 75% reads/25% writes
 •  Different mixture of random and sequential I/Os

The tests determined that drastic improvements were made with V-locity enabled versus disabled. With V-locity enabled, we found that performance rates improved around 50% on average. In one test case, IOps (I/Os per second) increased from 2,903 to 5,525, a performance rate improvement of 90%.  

 

 

 

 This chart shows the detailed test results of the 5 test variations:  

 

 

 

We also compared the results of the V-locity Dashboard running the same IOMeter benchmark, with V-locity disabled and then enabled and found some additional improvements.

With V-locity enabled, it was able to eliminate over 8 million I/Os from having to go through the network and storage to get satisfied which immensely increased the I/O capacity of the system.  By knowing the latency times of these ‘eliminated’ I/Os, another improvement to highlight is that it saved more than an hour of storage I/O time.   

 

 

 

Additionally, the workload (amount of data read/written) increased from 169GB to 273GB, meaning 60% more work was being done in the same amount of time.  

 

 

 

 

 

Customers can be confident that V-locity has successfully passed an exhaustive series of tests established by Citrix. The V-locity technology works effectively with Citrix solutions and can provide customers with 50% or more faster performance gain on their heaviest workloads. V-locity allows customers to “set it and forget it,” meaning that once it is installed, systems will instantly improve with little to no maintenance.

Our CEO, Jim D’Arezzo noted, “We are proud to partner with Citrix Systems. It’s important to remember that most I/O performance issues are caused by the operating system, particularly in the Windows environment. When compared to a hardware upgrade, the software solutions Condusiv offers are far more effective—both in terms of cost and result—in increasing overall system performance. We offer customers intelligent solutions that now combine our V-locity with Citrix XenDesk. We can’t wait to continue to work with the trusted partners in the Citrix Ready ecosystem.”

Case Study: Non-Profit Eliminates Frustrating Help Desk calls, Boosts Performance and Extends Useful Hardware Lifecycle

by Marissa Newman 9. September 2019 11:47

When PathPoint was faced with user complaints and productivity issues related to slow performance, the non-profit organization turned to Condusiv’s I/O reduction software to not only optimize their physical and virtual infrastructure but to extend their hardware lifecycles, as well. 

As technology became more relevant to PathPoint’s growing organization and mission of providing people with disabilities and young adults the skills and resources to set them up for success, the IT team had to find a solution to make the IT infrastructure as efficient as possible. That’s when the organization looked into Diskeeper® as a solution for their physical servers and desktops.

“Now when we are configuring our workstations and laptops, the first thing we do is install Diskeeper. We have several lab computers that we don’t put the software on and the difference is obvious in day-to-day functionality. Diskeeper has essentially eliminated all helpdesk calls related to sluggish performance.” reported Curt Dennett, PathPoint’s VP of Technology and Infrastructure.

Curt also found that workstations with Diskeeper installed have a 5-year lifecycle versus the lab computers without Diskeeper that only last 3 years and he found similar results on his physical servers that are running full production workloads. Curt observed, “We don’t need to re-format machines running Diskeeper nearly as often. As a result, we gained back valuable time for other important initiatives while securing peak performance and longevity out of our physical hardware assets. With limited budgets, that has truly put us at ease.”

When PathPoint expanded into the virtual realm, Curt looked at V-locity® for their VM’s and, after reviewing the benefits, brought the software into the rest of their environment. The organization found that with the powerful capabilities of Diskeeper and V-locity, they were able to offload 47% of I/O traffic from storage, resulting in a much faster experience for their users.

The use of V-locity and Diskeeper is now the standard for PathPoint. Curt concluded, “The numbers are impressive but what’s more for me, is the gut feeling and the experience of knowing that the machines are actually performing efficiently. I wouldn’t run any environment without these tools.”

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.
