The Condusiv blog shares insight into the issues surrounding system and application performance—and how I/O optimization software is breaking new ground in solving those issues.

Largest-Ever I/O Performance Study

by Brian Morin 28. January 2016 09:10

Over the last year, 2,654 IT Professionals took our industry-first I/O Performance Survey, which makes it the largest I/O performance survey of its kind. The key findings from the survey reveal an I/O performance struggle for virtualized organizations as 77% of all respondents indicated I/O performance issues after virtualizing. The full 17 page report is available for download at http://learn.condusiv.com/2015survey.html.

Key findings in the survey include:

- More than 1/3rd of respondents (36%) are currently experiencing staff or customer complaints regarding sluggish applications running on MS SQL or Oracle

- Nearly 1/3rd of respondents (28%) are so limited by I/O bottlenecks that they have reached an "I/O ceiling" and are unable to scale their virtualized infrastructure

- To improve I/O performance since virtualizing, 51% purchased a new SAN, 8% purchased PCIe flash cards, 17% purchased server-side SSDs, 27% purchased storage-side SSDs, 16% purchased more SAS spindles,       6% purchased a hyper-converged appliance

- In the coming year, to remediate I/O bottlenecks, 25% plan to purchase a new SAN, 8% plan to purchase a hyper-converged appliance, 10% will purchase SAS spindles, 16% will purchases server-side SSDs, 8% will   purchase PCIe flash cards, 27% will purchase storage-side SSDs, 35% will purchase nothing in the coming year

- Over 1,000 applications were named when asked to identify the top two most challenging applications to support from a systems performance standpoint. Everything in the top 10 was an application running on top of   a database

- 71% agree that improving the performance of one or two applications via inexpensive I/O reduction software to avoid a forklift upgrade is either important or urgent for their environment

As much as virtualization has provided cost-savings and improved efficiency at the server-level, those cost savings are typically traded-off for backend storage infrastructure upgrades to handle the new IOPS requirements from virtualized workloads. This is due to I/O characteristics that are much smaller, more fractured, and more random than they need to be.  The added complexity that virtualization introduces to the data path via the “I/O blender” effect that randomizes I/O from disparate VMs, and the amplification of Windows write inefficiencies at the logical disk layer erodes the relationship between I/O and data, generating a flood of small, fractured I/O. This compounding effect between the I/O blender and Windows write inefficiencies creates “death by a thousand cuts” regarding system performance, creating the perfect trifecta for poor performance – small, fractured, random I/O.

Since native virtualization out-of-the box does nothing to solve this problem, organizations are left with little choice but accept the loss of throughput from these inefficiencies and overbuy and overprovision for performance from an IOPS standpoint since they are twice as IOPS dependent than they actually need to be…except for Condusiv customers who are using V-locity® I/O reduction software to see 50-300% faster application performance on the hardware they already have by solving this root cause problem at the VM OS-layer.

Note - Respondents from companies with employee sizes under 100 employees were excluded from the results, so results would not be skewed by the low end of the SMB market.

The Gartner Cool Vendor Report in Storage Technologies: Vanity or Value

by Robert Woolery 22. April 2014 08:58

We all like lists that rank who is cool, best in class or top score in a buyer’s guide. Every year, Gartner releases their prized "Cool Vendor" selection. But is it just vanity for the vendor selected or is there actual, tangible value to the prospective customer that makes you care?

We believe one significant difference about the Cool Vendor Report compared to other reports is Gartner does a deep-dive examination of compelling vendors across the technology landscape, then upon selecting their "cool vendors" for the year, they reveal their analysis, why the vendor is cool, challenges the vendor faces and who should care.

Of all the technology companies on the landscape, Gartner chose to highlight four this year in the area of storage technologies, providing research into their innovative products and/or services.

When we were brainstorming our flagship product V-locity, we spoke to hundreds customers and we heard a common theme – performance problems in virtual environments whereby users were buying lots of hardware to solve an inherent software problem per the "I/O blender" effect.

As we dug in, a clearer picture emerged. We've become conditioned to medicating performance problems with hardware. And why not? In the past, performance gains were growing by 4X to 8X every ten years. Hardware was cheap. The price performance continued to improve every two years. And inertia, doing business as usual was low risk – buy more hardware because we’ve always done it that way and the financial folks understand the approach.

When we evangelize the problem of I/O growing faster than hardware could cost-effectively keep up and the need for a software only approach to easily cure it, we found the problem and solution resonated with many customers – webinar attendance ranged from 400 to 2,000 attendees. And while we are fast approaching 2,000 corporate installations, there are still customers wondering why they have not heard of the I/O problem we solve and our innovative way to solve it. They want some proof.

This is where the Gartner Cool Vendor report is helpful to IT users and their organizations. The reports help focus and reduce the learning curve on the relevant problems in IT, the innovative companies that warrant further investigation and highlight interesting new products and services that address issues in emerging trends.

The Cool Vendor Report can be read in the time it takes to have a cup of coffee. Not surprisingly, the Cool Vendor Reports are one of two top reports Gartner clients download.

Now for our vanity plug, Condusiv is listed in the Cool Vendor Report titled "Cool Vendors in Storage Technologies, 2014." This is usually only available to Gartner clients, but we paid for distribution rights so you could read it for free. Download Gartner's Cool Vendors in Storage Technologies Report

When Dave Cappuccio of Gartner Speaks, People Listen

by Robert Woolery 10. April 2014 01:32

As others entered the stage, there was perfunctory applause. However, when Dave entered a roar of applause erupted, and the event ground to a halt for several minutes.

Sitting in the audience at Gartner Symposium 2013 over the next several days I saw this reaction several times.  When Dave Cappuccio, Vice President and Chief of Research at Gartner speaks, people listen. 

He made the case for the “Infinite Data Center” concept – increasing data center performance and productivity without growing beyond the current facility.  He guided the audience through a strategy that allows IT organizations to grow revenue without increasing the IT budget. 

The strategies and concepts were not only thought provoking but inspired and challenged the audience to think about their roles differently.  How IT could provide leadership to their organizations dealing with a NEXUS of forces – convergence of social, mobility, cloud and information patterns that drive new business scenarios – that are innovative and disruptive on their own but together are revolutionizing business and society, disrupting old business models and creating new leaders.  

It was clear he had insights and answers to many of the issues and he could help organizations develop strategies that would address questions like “What are the IT inhibitors to transforming the business into a growth engine?”  “What strategies can a CIO employ to overcome the challenge of transforming the business without increasing the IT budget?” and “How can IT leaders explain this value to the CEO or CFO in business terms?”

From this inspiration, this Gartner webcast was born.  Dave tackles these issues and provides a construct that came to be used to answer these questions for each customer’s unique circumstances as our featured guest.  Moreover, Dave guides IT leaders in how to manage reactions from thought leadership that pushes organizations out of their traditional comfort zones so they can transform their business into a growth engine. 

Take a look and let us know your thoughts.
