Case Study: The University of Kansas Health System achieves dramatic Epic performance gains with Pure Storage

Pure Storage Delivers Epic Performance Gains at the University of Kansas Health System

The University of Kansas Health System, a large integrated healthcare provider with nearly 10,000 employees and two hospitals, needed to meet escalating performance requirements for its Epic electronic health record system. Upgrading the legacy spinning-disk storage to satisfy Epic’s IOPS demands looked prohibitively expensive and perpetuated a costly “rip-and-replace” cycle as data and performance needs grew.

After a rigorous proof-of-concept, the health system deployed Pure Storage all‑flash arrays, completing migration in two weeks. The new storage exceeded Epic performance targets, cut key Clarity report runtimes from 5½ hours to 20 minutes, reduced restore times from hours to about 10 minutes, and simplified development with fast snapshots. Additional benefits included much lower power/space use (replacing five racks with ~20U), 8:1–13:1 data reduction, and predictable, long‑term costs through Pure’s Evergreen program.
