The Biggest Missed Culprit in SQL Performance Troubleshooting

by Brian Morin 18. February 2015 09:53

"We didn't know how much of our SQL performance was being dampened by the nasty 'I/O blender' effect….."

As it turned out, it was HALF. 

That's right. Their systems were processing HALF as many MB/sec than they should due to the noise of all their VM workloads meeting and mixing at the point of the hypervisor. The first thing the "I/O blender" effect does is tax throughput, so your application performance becomes far more dependent on storage IOPS than it needs to be.

Read the full story how I.B.I.S., Inc. doubled performance of their CRM and ERP by eliminating the I/O
blender effect ->
 

So what is the "I/O blender" effect and how is it taxing application performance? 

The "I/O blender" effect is a phenomena specific to a virtual server environment where the I/O streams from disparate VMs are "funneled" together at the point of the hypervisor before sending out to storage a very random I/O stream that penalizes overall application performance.

Every organization that has virtualized has experienced this pain. They virtualized their applications only to discover mounting I/O pressure on the backend storage infrastructure. This was the unintended consequence of virtualization. Organizations save costs on the compute layer via virtualization only to trade those savings to backend storage where a forklift upgrade is necessary to handle the new random I/O demand.

In the case of I.B.I.S., Inc., their IT Director wanted to look into this problem a little further to see what could be done before reactively buying more storage hardware for improved performance.

"We wanted to try V-locity® I/O reduction software first to see if it could tackle the root cause problem as advertised at the VM level where I/O originates," said Kevin Schmidt, IT Director.

As much as IT departments lack monitoring tools that show exactly how much performance is dampened by the "I/O blender" effect, V-locity comes with an embedded benchmark to give a before/after picture of I/O reduction and demonstrate how much performance is improved by combatting this problem at the Windows operating system layer.

As it turned out, I.B.I.S., Inc.'s heaviest SQL workloads saw a 120% improvement in data throughput. Before V-locity, it took 82,000 I/Os to process 1GB of data. After V-locity, that number was cut to 29,000 I/Os per GB. Due to the increase in I/O density, instead of taking .78 minutes to process 1GB, it now only takes .36 minutes.

"Since we're no longer dealing with so many small split I/Os and random I/O streams, V-locity has enabled our CRM and ERP systems to process twice the amount of data in the same amount of time. The best part is that we didn't have to spend a single dime on expensive new hardware to get that performance," said Schmidt.

Announcing V-locity version 5

by Robert Woolery 28. February 2014 03:10

 It is not a daily increase, but a daily decrease. Hack away at the inessentials.” - Bruce Lee

Removing the nonessential is a key element of simplicity and efficiency, yet it is deceptively difficult to accomplish. We need reminding. And then more reminding.

When I get too caught-up in what’s on my desk, in Outlook, on the calendar, I get on the phone with one of our V-locity customers and I remember what we’re doing here. Why I pull into the Condusiv parking lot every day. We hack away at the inessentials, and in doing so, we enable our customers to work better, faster, more efficiently, without buying more hardware to achieve it.

We’re very pleased to announce V-locity version 5. In this release, V-locity is now bundled with the V-locity Management Console, giving IT organizations the visibility, command, and control to optimize applications and maximize users’ efficiency—proactively managing I/O and its impact on performance across the entire environment.

Enterprise-class and cloud-ready, the V-locity Management Console enables seamless deployment and centralized management of V-locity on-premises in a virtual or physical environment, or in the cloud. With central control of assets, configuration, and performance management, admins can deploy V-locity to thousands of VMs and physical servers in just five clicks, manage a large number of licenses, and support various pricing models.

The highlights:

  • Central command and control with web-based management from a single pane of glass across geographic locations
  • Fast, non-disruptive deployment to even the most complex multi-site and hybrid environments
  • Auto-detection of virtual and physical server environments for easy asset and license management
  • Flexible pricing options from site licenses, subscription, or perpetual volume licenses
  • Single solution for virtual and physical servers
  • V-locity alert management with email notifications based on customized I/O performance profiles for any application
  • Ongoing performance validation of V-locity for ROI reporting capabilities


No more needle-in-the-haystack approach to troubleshooting. No more contending with a disjointed view of the environment. No more lack of understanding what’s happening from server to network to storage.

Maybe you’ve virtualized, maybe you’ve gone cloud, maybe you’re using VDI to ease management of so many endpoints… whatever the case—in any of these scenarios—the marketing message is always simplification.

And while simplification might be partly real, each of these strategies comes with an inherent problem: I/O. More and more I/O, which leads to serious performance degradation, more hardware to throw at the problem, increasingly formidable data centers, and more hours spent troubleshooting and stressing out. The root of the problem is I/O.

And V-locity is software that dramatically reduces I/O—literally overnight. And now it comes with the V-locity Management Console to make managing complex environments more efficient than ever.

So today I channel Bruce Lee and his thoughts on simplicity, on hacking away at the inessentials. That’s what we’re doing at Condusiv. That’s the vision of V-locity version 5. Enabling organizations to perform faster, better, simpler, happier.

No more delays in business critical ERP apps

Great customer success:

“Diskeeper is vital; it helps our business with what we consider preventative maintenance.  We also feel that this software keeps our server and our server apps running smoothly and efficiently as we have 50 users who require simultaneous access to our data for operation of our facilities.  I run Diskeeper on my primary ERP server which is our business critical application.  We saw within the first day, that previous delays in processing data had decreased.  Our current ERP, called Eagle, was installed and implemented about 2.5 years ago and is made by a company called DMS (now owned by AFS).  This server is one of four we run Diskeeper on.  Since we are food warehousing company, we chose an application that was built specifically for our industry.  Also as we are a company that ships and processes orders 24 hours a day, 6 days a week, being able to run at optimal performance is always crucial for us. “
