Surprising Results: Meditech EHR Performance Survey

by Brian Morin 12. January 2015 04:42

According to our recent survey to Meditech hospitals, half receive staff or customer complaints regarding EHR performance while the other half do not. Since virtualizing, 62% purchased a new SAN, 10% added SAS spindles, 20% added server-side SSDs or PCIe flash, 24% added storage-side SSDs, 38% added additional servers, and 24% have not seen I/O performance issues. In the coming year, 29% will purchase a new SAN, 5% will add SAS spindles, 15% will add server-side SSDs, and 24% will add storage-side SSDs.

Most notably, merely 1/3rd were aware of the Meditech service bulletins alerting Meditech 5.x/6.x users of the FAL size growth issue from severe fragmentation that can result in unscheduled downtime if left unchecked.

To date, 65 Meditech hospitals have turned to Condusiv’s V-locity® I/O reduction software for automatic FAL remediation and improved EHR performance, so they no longer have to worry about unscheduled downtime and achieve 50-300% more performance from existing systems.

Since a lot of Meditech hospitals don’t fully understand the FAL size growth issue and how that affects their systems, here is a brief explanation:

When someone mentions heavy fragmentation on a Windows NTFS Volume, the first thing that usually comes to mind is performance degradation. While performance degradation is certainly bad, what’s worse is application failure. That is exactly what happens in severely fragmented environments when no more data can be added to files or no more files can be inserted under a folder file. This Windows limitation has a direct impact on the availability of the Meditech application, as several Meditech hospitals know too well. It is a show-stopper that can stop any hospital in its tracks until the problem is remediated.

The FAL size has an upper limitation of 256KB. When that limit is reached, no more mapping pointers can be added, which means NO more data can be added to the file. And, if it is a folder file which keeps track of all the files that reside under that folder, NO more files can be added under that folder file.

So what can be done about it?

The logical solution would be – why not just defragment the volume? The problem is that traditional defragmentation utilities can decrease the number of mapping pointers, but will not decrease the FAL size. Furthermore, due to limitations within the file system, traditional methods of defragmenting files cause the FAL size to grow even larger, making the problem worse even though you are attempting to remediate it.

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.

$2 Million Cancelled

by Brian Morin 22. July 2014 08:52

CHRISTUS Health cancelled a $2 Million order.

Just before they pulled the trigger on a $2 Million storage purchase to improve the performance of their electronic health records application (MEDITECH®), they evaluated V-locity® I/O reduction software.

We actually heard the story first hand from the NetApp® reseller in the deal at a UBM Xchange conference. He thought he had closed the $2 Million deal only to find out that CHRISTUS was doing some testing with V-locity. After getting the news that the storage order would not be placed, he met us at Xchange to find out more about V-locity since "this V-locity stuff is for real."

After an initial conversation with anyone about V-locity, the first response is generally the same – skepticism. Can software alone really accelerate the applications in my virtual environment? Since we are conditioned to think only new hardware upgrades can solve performance bottlenecks, organizations end up with spiraling data center costs without any other option except to throw more hardware at the problem.

CHRISTUS Health, like many others, approached us with the same skepticism. But after virtualizing 70+ servers for their EHR application, they noticed a severe performance hit from the “I/O blender” effect. They needed a solution to solve the problem, not just more hardware to medicate the problem on the backend.

Since V-locity comes with an embedded performance benchmark that provides the I/O profile of any VM workload, it makes it easy to see a before/after comparison in real-world environments.

After evaluation, not only did CHRISTUS realize they were able to double their medical records performance, but after trying V-locity on their batch billing job, they dropped a painful 20 hour job down to 12 hours.

In addition to performance gains, V-locity also provides a special benefit to MEDITECH users by eliminating excessive file fragmentation that can cause the File Attribute List (FAL) to reach its size limit and degrade performance further or even threaten availability.

Tom Swearingen, the manager of Infrastructure Services at CHRISTUS Health said it best. "We are constantly scrutinizing our budget, so anything that helps us avoid buying more storage hardware for performance or host-related infrastructure is a huge benefit."

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.
