This is Why a Top Performing School Recommended Condusiv Software and Doubled Performance

by Dawn Richcreek 6. December 2018 05:04

Lawnswood School is one of the top performing educational institutions in the UK. Their IT environment supports a workload that is split between approximately 1200 students and 200 staff.  With 1400 people and various programs and files to support, they were in search of something to help extend the life of their hardware and increase performance. They turned to Condusiv®’s V-locity® and Diskeeper® to extend the life of their storage hardware and maintain performance for their students and staff.

"Condusiv's V-locity software eliminated almost 50% of all storage I/O requests from having to be dealt with by the disk storage (SAN) layer, and that meant that when replacing the old SAN storage with a 'like-for-like' HP MSA 2040, V-locity gave me the confidence to make the purchase without having to over-spend to over-provision the storage in order to cope with all the excess unnecessary storage I/O traffic that V-locity efficiently eliminates,"said Noel Reynolds, IT Manager at Lawnswood School. Before upgrading his SAN, Noel was able to extend the life of the HP MSA 2000 SAN for 8 years “thanks to Condusiv’s I/O reduction software”.

Knowing how well the IT environment was performing at Lawnswood School, another school reached out to Noel for help, as their IT environment was almost identical, but suffering from slow and sluggish performance. They also had three VMware hosts of the same specification, the older HP MSA 2000 SAN storage and workloads that were pretty much identical. Noel Reynolds noted that: "They were almost a 'clone' school."

He continued: "I did the usual checks to discover why it wasn't working well, such as upgrading the firmware, checking the disks for errors and found nothing wrong other than bad storage performance. After comparing the storage latency, I found that Lawnswood School's disk storage was 20 times faster, even though the hardware, software and workload types were pretty much identical."

"We identified six of the 'most hit' servers and installed Condusiv's software on them. Within 24 hours, we saw a 50% boost in performance. Visibly improved performance had been returned to the users, and this really helped the end user experience.

A great example of a real-world solution." Noel concluded

Finance Company Deploys V-locity I/O Reduction Software for Blazing Fast VDI

by Dawn Richcreek 27. November 2018 05:27

When the New Mexico Mortgage Finance Authority decided to better support their users by moving away from using physical PCs and migrating to a virtual desktop infrastructure, the challenge was to ensure the fastest possible user experience from their Horizon View VDI implementation.

“Anytime an organization starts talking about VDI, the immediate concern in the IT shop is how well we will be able to support it from a performance standpoint to ensure a pristine end user experience. Although supported by EMC VNXe flash storage with high IOPS, one of our primary concerns had to do with Windows write inefficiencies that chews up a large percentage of flash IOPS unnecessarily. When you’re rolling out a VDI initiative, the one thing you can’t afford to waste is IOPS,” said Joseph Navarrete, CIO, MFA.

After Joseph turned to Condusiv’s “Set-It-and-Forget-It®” V-locity® I/O reduction software and bumped up the memory allocation for his VDI instances, V-locity was able to offload 40% of I/O from storage resulting in a much faster VDI experience to his users. When he demo’d V-locity on his MS-SQL server instances, V-locity eliminated 39% of his read I/O traffic from storage due to DRAM read caching and another 40% of write I/O operations by solving Windows write inefficiencies at the source.

After seeing the performance boost and increased efficiency to his hardware stack, Joseph ensured V-locity was running across all his systems like MS-Exchange, SharePoint, and more.

“With V-locity I/O reduction software running on our VDI instances, users no longer have to wait extra time. The same is now true for our other mission critical applications like MS-SQL. The dashboard within the V-locity UI provides all the necessary analytics about our environment and view into what the software is actually doing for us. The fact that all of this runs quietly in the background with near-zero overhead impact and no longer requires a reboot to install or upgrade makes the software truly “set and forget,” said Navarrete.

Fix SQL Server Storage Bottlenecks

by Spencer Allingham 23. October 2018 20:58

No SQL code changes.
No Disruption.
No Reboots.
Simple!

 

Condusiv V-locity Introduction

 

 

Whether running SQL in a physical or virtualized environment, most SQL DBAs would welcome faster storage at a reasonable price.

The V-locity® software from Condusiv® Technologies is designed to provide exactly that, but using the storage hardware that you already own. It doesn't matter if you have direct attached disks, if you're running a tiered SAN, have a tray of SSD storage or are fortunate enough to have an all-flash array; that storage layer can be a limiting factor to your SQL Server database productivity.

The V-locity software reduces the amount of storage I/O traffic that has to go out and be processed by the disk storage layer, and streamlines or optimizes the data which does have to still go out to disk.

The net result is that SQL can typically get more transactions completed in the same amount of time, quite simply because on average, it's not having to wait so much on the storage before being able to get on with its next transaction.

V-locity can be downloaded and installed without any disruption to live SQL servers. No SQL code changes are required and no reboots. Just install and typically you'll start seeing results in just a few minutes.

Microsoft SQL Server I/O Reliability Certification LogoBefore we take a more in-depth look at that, I would like to briefly mention that last year, the V-locity software was awarded the Microsoft SQL Server I/O Reliability Certification. This means that whilst providing faster storage access, V-locity didn't adversely affect the required and recommended behaviors that an I/O subsystem must provide for SQL Server, as defined by Microsoft themselves.

Microsoft ran tests for this in Azure, with SQL 2016, and used HammerDB to generate an online transaction processing type workload. Not only was V-locity able to jump through all the hoops necessary to achieve the certification, but it was also able to show an increase of about 30% more SQL transactions in the same amount of time.

In this test, that meant roughly 30% more orders processed.

They probably could have processed more too, if they had allowed V-locity a slightly larger RAM cache size.

Use the V-locity software to not only identify those servers that cause storage I/O issues, but fix those issues at the same time.

Cultech Limited Solves ERP and SQL Troubles with Diskeeper 18 Server

by Spencer Allingham 8. October 2018 09:11

Before discovering Diskeeper®, Cultech Limited experienced sluggish ERP and SQL performance, unnecessary downtime, and lost valuable hours each day troubleshooting issues related to Windows write inefficiencies.

As an internationally recognized innovator and premium quality manufacturer within the nutritional supplement industry, the usual troubleshooting approaches just weren’t cutting it. “We were running a very demanding ERP system on legacy servers and network. A hardware refresh was the first step in troubleshooting our issues. As much as we did see some improvement, it did not solve the daily breakdowns associated with our Sage ERP,” said Rob, IT Manager, Cultech Limited.

After upgrading the network and replacing ERP and SQL servers and not seeing much improvement, Rob further dug into troubleshooting approaches and SQL optimizations. With months of troubleshooting and SQL optimizations and no relief, Rob continued to research and find a way to improve performance issues, knowing that Cultech could not continue to interrupt productivity multiple times a day to fix corrupted records. As Rob explains, “I was on support calls with Sage literally day and night to solve issues that occurred daily. Files would not write properly to the database, and I would have to go through the tedious process of getting all users to logout of Sage then manually correct the problem – a 25-min exercise. That might not be a big deal every so often, but I found myself doing this 3-4 times a day at times.”

In doing his research, Rob found Condusiv’s® Diskeeper Server and decided to give it a try after reading customer testimonials on how it had solved similar performance issues. To Cultech’s surprise, after just 24-hours of being installed, they were no longer calling Sage support. “I installed Diskeeper and crossed my fingers, hoping it would solve at least some of our problems. It didn’t just solve some problems, it solved all of our problems. I was calling Sage support daily then suddenly I wasn’t calling them at all,” said Rob. Problems that Rob was having to fix outside of production hours had been solved thanks to Diskeeper’s ability to prevent fragmentation from occurring. And in addition to recouping hours a day of downtime during production hours, Cultech was now able to focus this time and energy on innovation and producing quality products.

“Now that we have Diskeeper optimizing our Sage servers and SQL servers, we have it running on our other key systems to ensure peak performance and optimum reliability. Instead of considering Windows write inefficiencies as a culprit after trying all else, I would encourage administrators to think of it first,” said Rob.

Big Data Boom Brings Promises, Problems

by Dawn Richcreek 7. September 2018 04:40

By 2020, an estimated 43 trillion gigabytes of data will have been created—300 times the amount of data in existence fifteen years earlier. The benefits of big data, in virtually every field of endeavor, are enormous. We know more, and in many ways can do more, than ever before. But what of the challenges posed by this “data tsunami”? Will the sheer ability to manage—or even to physically house—all this information become a problem?

Condusiv CEO Jim D’Arezzo, in a recent discussion with Supply Chain Brain, commented that “As it has over the past 40 years, technology will become faster, cheaper, and more expansive; we’ll be able to store all the data we create. The challenge, however, is not just housing the data, but moving and processing it. The components are storage, computing, and network. All three need to be optimized; I don’t see any looming insurmountable problems, but there will be some bumps along the road.”

One example is healthcare. Speaking with Healthcare IT News, D’Arezzo noted that there are many new solutions open to healthcare providers today. “But with all the progress,” he said, “come IT issues. Improvements in medical imaging, for instance, create massive amounts of data; as the quantity of available data balloons, so does the need for processing capability.”

Giving health-care providers—and professionals in other areas—the benefits of the data they collect is not always easy. In an interview with Transforming Data with Intelligence, D’Arezzo said, “Data center consolidation and updating is a challenge. We run into cases where organizations do consolidation on a ‘forklift’ basis, simply dumping new storage and hardware into the system as a solution. Shortly thereafter, they often discover that performance has degraded. A bottleneck has been created that needs to be handled with optimization.”

The news is all over it. You are experiencing it. Big data. Big problems. At Condusiv®, we get it.  We’ve seen users of our I/O reduction software solutions increase the capability of their storage and servers, including SQL servers, by 30% to 50% or more. In some cases, we’ve seen results as high as 10X initial performance—without the need to purchase a single box of new hardware. The tsunami of data—we’ve got you covered.
