Global ROC’s Virtualized HMI Solution for a Texas Power Plant

The Challenge

Facing increasing concerns about aging hardware, a Texas power plant relied on Human-Machine Interface (HMI) systems integral to their operations.

The threat of hardware failure loomed large, potentially causing downtime and operational disruptions. Additionally, obtaining replacement parts for their aging HMI hardware became a growing challenge.


Our Solution

Global ROC orchestrated a transformative solution by virtualizing the HMIs using VMware vSphere.

This virtualization platform enabled multiple HMIs to operate on a single, reliable server, ensuring redundancy and safeguarding against hardware failures.

The shift to virtualization not only addressed the immediate threat but also provided long-term benefits in terms of performance, scalability, and manageability.
