Case Study: The University of Texas Health Science Center at Houston achieves optimal flash-array selection and real-time metro-cluster performance visibility with Virtana VirtualWisdom

VirtualWisdom allows UTHealth to select optimal flash storage array that matches application I/O profile

The University of Texas Health Science Center at Houston faced limited visibility across a dense, converged metro-cluster environment that supported 1,500 VMs and critical clinical and academic applications. Manual collection of disparate logs meant no real‑time insight and inconsistent performance—some applications experienced up to 10x delays between data centers—so UTHealth engaged Virtana and its VirtualWisdom Infrastructure Performance Assessment (IPA) and Infrastructure Performance Management (IPM) capabilities to diagnose and baseline the environment.

Virtana deployed VirtualWisdom probes and analytics to provide end-to-end I/O visibility, correlate VM, network and storage metrics, and run an IPA to guide storage selection and configuration. That analysis uncovered a Converged Network Adapter mismatch causing the 10x I/O delays, enabled remediation of data-center sync issues, optimized the storage network, reduced migration and change risk, and delivered measurable, real‑time insight that allowed UTHealth to select optimal flash arrays and demonstrate proven performance improvements to stakeholders.
