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

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.”

SQL Batch Job Hell

by Brian Morin 1. October 2014 04:16

ASL was in SQL batch job hell.

A regular import of 150 million records into their SQL database would take 27 hours to complete.

ASL’s account team and clients needed access to the most current data immediately, but the 27 hour batch job meant that access would slip a full day of production or even two. That wasn’t acceptable as some clients would hold back business while waiting on new data to come online.

“Typically, IT professionals respond to application performance issues by reactively buying more hardware. Without the luxury of a padded budget, we needed to find a way to improve performance on the hardware infrastructure we already have,” said Ralph Ortiz, IT Manager, ASL Marketing.

ASL upgraded their network to 10GbE and was looking at either a heavy investment in SSD or doing a full rip-and-replace of the SAN architecture before its full lifecycle. Since that kind of hardware investment wasn’t in the budget, they decided to take a look at V-locity® I/O reduction software.

“I was very doubtful that V-locity could improve my I/O performance through a software-only solution. But with nothing to lose, we evaluated V-locity on our SQL servers and were amazed to see that, literally overnight, we doubled throughput from server to storage and cut our SQL batch job times in half,” said Ortiz.

After deploying V-locity, SQL batch jobs that used to take 27 hours to complete now take 12–14 hours to complete. The weekly college database import that used to take 17 hours to complete is now down to 7 hours.
