The Total Economic Impact™ Of Pure Storage FlashArray Storage Solutions For VDI

At the beginning of 2016, Pure Storage commissioned Forrester Consulting to conduct a Total Economic Impact™ (TEI) study to examine the potential return on investment (ROI) customers may realize by deploying Pure Storage FlashArray storage solutions for virtual desktop infrastructure (VDI) environments. The purpose of this study is to provide readers with a framework to evaluate the potential financial impact of Pure Storage solutions for VDI. From the information provided in the interviews, Forrester has constructed a Total Economic Impact (TEI) framework for those organizations considering investing in Pure Storage. The objective of the framework is to identify the benefits, costs, flexibility, and risk factors that affect the investment decision.

Benefits of Pure Storage’s Purity operating system

Increased User Productivity Using Tap-And-Go

There are about 1,300 providers taking advantage of tap-and-go, each “tapping” an average of 40 times a day and saving 20 seconds with each login versus the pre-Pure Storage legacy environment. That equates to about 13 minutes saved per day, per provider, and an aggregate of 16,900 minutes, or 282 hours per day saved.

Opex Cost Reduction

A small amount of flash capacity can handle the performance load of dozens of drives that represent more potential points of failure within a disk array. With fewer components to worry about, St. Luke’s told Forrester that Pure Storage FlashArrays are overall easier to maintain than hard disks and have less redundant array of independent disks (RAID) rebuild operations, which typically lead to performance degradation, downtime, and administrative labor to remedy.

Save Costs

Prior to investing in Pure Storage, St. Luke’s was scheduled to replace its data center air conditioning unit at a cost of $250,000. The projected growth in legacy disk storage was going to require more cooling. After replacing its legacy storage with Pure Storage FlashArrays, St. Luke’s is now able to defer replacing the air conditioning unit indefinitely, saving $250,000.

Avoid Excess Storage Cost

Previous to investing in Pure Storage, St. Luke’s had considered adding additional virtual host servers and disk storage capacity to circumvent the performance degradation and inefficiencies in its VDI environment. The alternative goal was to find a new solution to support its growing virtual environment at a lower overall capital cost and improve performance.

Power and Cooling Services

St. Luke’s reported significant power and cooling savings when it replaced legacy disk storage with Pure Storage FlashArrays. Its power and cooling savings totaled $22,679 (risk-adjusted) over three years and assumes a cost per KWH for power of $0.14 and a cost per KWH for cooling of $0.10 (see Table 5). We have risk-adjusted the savings downward by 7% to reflect regional KWH rate differentials.
