Tintri VMstore Systems Simplify Storage Management, Reduce Datacenter Footprint, and Improve Application Performance for Over 10,000 End Users
Austin Radiological Association (ARA) has been delivering high quality imaging services to the people of Central Texas since 1954. ARA currently operates 17 outpatient imaging centers and provides professional radiology services for over 20 area hospitals. Delivering exceptional patient care goes hand in hand with staying on the cutting edge of technology. “We’ve gone through three major IT re-architectures over the last ten years,” noted Todd Thomas, Chief Information Officer at ARA. “The most recent one included an array that was a carryover from the old Fibre Channel days. Even though it was a step up from our previous infrastructure, it still required a highly trained IT person that understood how to provision storage and how virtual machines ran on that array.”
Supporting a Wide Range of Radiology and Business Applications
ARA relies on three primary radiology applications: a medical imaging archive application by Fuji Medical Systems; a radiology information system provided by Medinformatix, and radiology dictation by Nuance Powerscribe 360. In addition to the three radiology applications, the IT team is also responsible for managing approximately 300 additional applications for supporting ARA’s business services and medical operations.
“We support 850 internal users,” Thomas said. “In addition, we provide support for roughly 10,000 users outside our organization who utilize a subset of our applications — receiving of orders and sending of images to our referring physicians. We also allocate a portion of our infrastructure for several multidisciplinary facilities and hospitals in central Texas, where we enable them to outsource their image management to us. We run their applications to our systems and store their images on our IT infrastructure simplifying their image management.”
“Tintri is providing a much lower cost of ownership than our legacy array. It's also easier to manage and scale as our environment grows, and we have gained a lot of flexibility by automating our replication and restore processes using SyncVM. All of these benefits made it really easy to justify upgrading from our legacy system to Tintri.”

Preparing for a Technology Refresh
ARA’s latest refresh of its data center infrastructure came in late 2011. A few years later, the existing storage platform came to the end of OEM maintenance which challenged ARA to begin thinking about what its future datacenter infrastructure might look like. “We focused on storage first because that was the platform that takes the most skill to deploy and manage,” Thomas noted. “We wanted to find a solution that was much simpler to use—where the technology would do all of the heavy lifting for us so we wouldn’t have to train on expanded archaic commands. We didn’t want to rely on storage specialists anymore. The chosen systems should be easy enough for anyone on our IT staff to do everything the business requires.”
“We’ve been following Tintri for a number of years,” Thomas shared. “When we looked at re-architecting our data center and moving off the previous vendor’s storage in early 2015, we brought Tintri back in to see their newest storage solution. Our environment is now 98% virtualized, so Tintri is the perfect fit for our organization. Tintri was built from the ground up for virtual environments, the close synergies between our virtualization strategy and the VMstore hardware platform made it a very easy decision to move up to Tintri.”
ARA purchased four Tintri systems and installed them at two data centers in an active-active configuration. ARA is now running all of its virtual machines, databases, radiology and business applications on Tintri.
“We initially fell in love with the Tintri box because of its ease-of-use,” Thomas shared. “The interface is so intuitive we were able to eliminate the need of a high level SAN engineer and our Windows server administrator can easily provision space. We now rely on a ‘general-purpose’ server person for our Tintri environment, as opposed to a higher salaried storage engineer for the legacy environment.”
“Managing Tintri is pretty straight forward,” noted Terrence Jones, Cloud Engineer at ARA. “The best part is we went from managing 80+ LUNS to flat file systems. When we did have performance issues on the legacy systems, we would have to rely on the legacy system’s performance analyzer, making troubleshooting difficult. I’m happy I can easily get near real-time statistics at the VM level with Tintri, instead of the LUN level with our legacy systems.”
All of ARA’s applications and databases are performing better on the Tintri systems, according to Thomas. “Our data analysis team have been raving about the speed of the new Tintri systems,” he said. “Our analysts run a lot of large database queries in order to generate a series of very complex reports. Upon installation of Tintri, the data analytics team reported a reduction in run time for one of their reports from 6 hours to under 30 minutes.”
Footprint and Power Savings
The Tintri systems also consume far less power and floor space than the previous storage systems. The legacy systems were rated to use 1.2KW in standby and 5.6KW is operation. Tintri is rated at (nominal) 680 watts—equating to a 4X reduction in power consumption. “We moved from a very large array that took up an entire rack,” Thomas said. “The four Tintri systems fit in the bottom of one rack, consuming only about a quarter of the space of our legacy array. Plus, Tintri is very good at deduplication and compression. We have obtained between 1.7 to 2.3x compression across our four Tintri systems.”
Using Tintri SyncVM for Backup and Recovery Workflows
ARA recently received a request from one of its clients for a ‘classic’ backup solution, due to an issue they ran into with failover and restore testing using the existing replication software. “The restore failed on one of their servers, and the client was not happy when they had to rebuild that system from scratch,” noted Thomas. “They wasted a lot of administrative time. That's what convinced us to look at Tintri SyncVM.”
ARA is now switching off of its existing replication software. Tintri SyncVM provides efficient copy data management at a VM-level—regardless of the VM size—and with no loss of performance history. It also enables ARA to restore environments very quickly. “There are those that say, ‘Why are you going back to an array-based replication strategy when the software you had worked across multiple arrays?’” Thomas shared. “Tintri’s replication solution gives us the scripting capability and flexibility to create development environments on-the-fly. In addition to being able to create snapshots that satisfied our clients’ backup needs, we were also able to reclaim a lot of compute and storage resources back from our array using SyncVM.”
“ARA is committed to providing excellent patient care which requires our IT organization to stay abreast of technology changes that will enhance our solutions for our referring providers and drive efficiency in our internal operations. The solution we selected from Tintri allows us to easily manage and scale as our environment grows while providing a lower cost of ownership than our legacy array. We have also gained a lot of flexibility by automating our replication and restore processes using SyncVM. All of these benefits made it easy to justify upgrading from our legacy system to Tintri,” Thomas concluded.
