Case Study: Wilson Bank & Trust achieves 90% latency reduction and fast app/log-in performance with Pure Storage FlashArray

Wilson Bank & Trust’s Investment In Pure Storage Pays Big Dividends

Wilson Bank & Trust, a Tennessee-based community bank known for early adoption of technology, ran into severe performance problems after virtualizing desktops and applications with Citrix on VMware. Their legacy spinning‑disk SAN produced persistent latency (5–11 ms) that caused long Citrix log‑ins and sluggish critical apps—sometimes logins taking up to 30 minutes—disrupting productivity and driving repeated help‑desk complaints.

With help from system integrator Hogan Consulting Group, the root cause was identified in two hours and a Pure Storage FlashArray was deployed within days. Within 24 hours production workloads were running on flash, latencies dropped to ~1 ms or less, application and login performance improved dramatically, help‑desk calls fell, deduplication delivered ~5:1 data reduction, disaster‑recovery testing was simplified, and the bank can now roll out new services faster.
