Looking at Flash Storage Case Studies

Descriptions of the technology and product features are certainly useful in introducing a subject like flash and hybrid storage arrays, but sometimes seeing concrete examples helps you gain a better understanding of the actual value of technology and features. In this chapter, you see a couple of examples that show how Tegile’s storage arrays benefited a medical services firm and a school district.

Using Virtualization to Support Medical Care

Oklahoma Heart Hospital is a physician-owned facility that brings world-class medical expertise and compassion to the care of every patient, to ensure a patient-centered care experience that delivers better outcomes. As the nation’s first all-digital hospital, Oklahoma Heart Hospital saves valuable time for patients by making information readily available to doctors and nurses. X-rays, lab results, vital signs and medications are right at the caregivers’ fingertips. This approach has helped the hospital achieve a ranking in the top 1 percent nationally for patient satisfaction.

Oklahoma Heart Hospital has embraced virtualization to support its mission-critical applications. With a traditional tiered storage model in place, Oklahoma Heart Hospital wanted to evaluate new options that would allow faster boot times and quicker reads to benefit its Citrix XenDesktop VDI environment.

With speed and performance being the main criteria required in building its new storage infrastructure, the IT staff at Oklahoma Heart Hospital began to look for the fastest, highest-performing SAN hardware available.

Oklahoma Heart Hospital brought in the best-performing solutions with the largest amounts of flash from major storage vendors to run real-world tests in the hospital’s production environment to measure, compare and decide which would be the best fit. Results were recorded and evaluated against each other. After evaluating all of the solutions, Oklahoma Heart Hospital decided to implement a Tegile All-Flash Array, which delivers maximum performance, high density, and compelling economics.

Tegile supports the Citrix virtualization environment for Oklahoma Heart Hospital’s main facilities with plans to replicate snapshots to a satellite campus. Currently, the hospital hosts more than 300 Citrix XenApp Servers and hundreds of virtual apps and VDI desktops, as well as mock and training environments. As additional doctors, nurses and staff commit to VDI, the hospital expects to roll out to 1,500 desktops.

Making the Grade in Desktop Virtualization

School District 27J provides educational services to approximately 16,000 students in Colorado. The staff and educators work to ensure that all students have the knowledge, skills, and attitudes needed for present and future competence and success. As part of this commitment, the district sought to create an online computing environment that leveraged a virtual desktop infrastructure, ensuring that teachers had access to their district resources at all times, which allowed them to fully support students both inside and outside the classroom.

The district launched its virtual desktop infrastructure (VDI) environment with a 100-desktop pilot program with the expectation that it would later scale to 800 desktops. As the system went live on the first day of the school year, the resulting boot storm from teachers logging in crashed the backend of the infrastructure – the SAN was undersized and basically wasn’t going to work.

The CIO of the school district scurried for other storage options that could quickly overcome the hardware failure. After looking at other solutions that could take up to 30 days to deliver, the district needed help sooner and decided on Tegile Systems.

Tegile assessed the needs of the district quickly and implemented a solution in the middle of the outage. Tegile delivered the hybrid solution within days of placing the order.

School District 27J currently has implemented two Tegile units to support its 866 virtual desktops. Desktop delivery times that were initially measured in hours now only take 14 seconds. With its built-in compression and de-duplication features, the school district reduced the 13.5 TB of storage utilized on one storage pool to only 8 TB, and the units’ performance enhancements have convinced staff that they can successfully accelerate their 3-year plan for offering VDI from teachers to libraries to students.
