If you’ve been in the IT infrastructure business for a while, you know how tough it is to show real ROI on your management investments. You’re often too busy with day-to-day activities to spend time accounting for spending and savings. But quite often, we have conversations with customers who found a savings so compelling and obvious that it really didn’t take any sleuthing to discover. Here are some anecdotes from some of those conversations that I think you’ll find interesting. If you’d like to learn more about any of these, just email firstname.lastname@example.org and we’ll put you in touch with the VI field team who covers the account.
For our first example, the U.S. Air Force used VirtualWisdom to identify inefficiencies and opportunities to improve system-wide operations and avoid forecasted costs, saving their department $100 million in long-term IT upgrade and infrastructure maintenance costs.

Soon after a Midwest insurance company deployed VirtualWisdom, they analyzed their storage port usage and found that they were way overprovisioned — Average front-end port utilization was under 3%. They began buying only the ports they needed and redeployed those that were barely being used. This cut their overall port count in half over the course of a couple of years. At approximately $3,000 per port, the savings exceeded $180,000. Though not part of the ROI per se, they also moved workloads to underutilized ports to even out workloads for more consistent utilization and performance. It was also uncovered that several SAN network bottlenecks existed, and by performing an enterprise queue depth optimization we were able to cut average response times for key applications in half.
At another, larger insurer, during the two-week onsite POC, we found more than 11,000 orphaned LUNs, capacity for which they were paying a monthly fee to their Service Provider. They were not eager to share the cost, but at an average size of approximately 100GB, that was more than 1PB of wasted space.
One of the very largest financial institutions in the U.S. changed how they deployed storage by cutting their storage port distribution in half because of the data from VI. Since then, they have demonstrated around $1.5 million in savings at their new data centers.
Before deploying VirtualWisom, yet another Top 5 financial institution had purchased fully configured arrays with 96 Fibre-Adaptor ports on each array. Using VirtualWisdom analytics, they now only deploy between 32-48 ports. Savings were spread across eight arrays, and if you estimate a cost of $3,000 per port, it’s a savings of at least $800,000 and probably over $1 million.
A Fortune 100 packaged consumer goods company and large SAP user was tasked with simultaneous migration, consolidation, and virtualization projects. In addition to mitigating the risk of these changes, they saw a 75% drop in trouble tickets with an associated yearly OPEX savings of over $2.6 million, thanks to improved and easier to use analytics.
And lastly, an environmental management company is the U.S. was running into performance problems and their storage vendor recommended the purchase of a virtualizer and an additional storage pod. By running our Queue Depth Analytic and embarking on an enterprise wide queue depth optimization project, they fixed the slowdowns, cut response times by two thirds, and avoided over $200,000 of CAPEX for additional gear.
As I mentioned, if you’d like to dig into any of these, we find that individuals are usually okay with talking with others 1:1, even if their legal departments don’t want to do public case studies.
