JetStor Delivers 80 PB High-Density Archive for Government Agency Using WD’s Trusted High-Capacity Ultrastar Drives

Public-sector IT teams face a distinct challenge at this scale: growing storage capacity economically without disrupting active production networks or retraining operations staff. JetStor addressed this by standardizing the entire deployment into repeatable POD building blocks—each anchored by WD Ultrastar DC HC590 26 TB SAS 7200RPM drives—across 132 JetStor XS3324D 4U 24-bay systems and 3,200 drives total. The result is a dual Fibre Channel fabric architecture that supports seamless expansion while keeping infrastructure management straightforward and predictable from day one.
“When a government agency reaches this scale, the architecture has to be predictable from day one and stay serviceable as it grows,” said Gene Leyzarovich, Founder of JetStor. “We standardized the deployment into repeatable POD building blocks and paired them with WD 26 TB Ultrastar drives to deliver an active archive that scales cleanly, stays isolated on Fibre Channel, and remains straightforward to operate.”
“Across both public and private sectors, the exponential growth of data is driving the need for storage solutions that deliver durability, predictable performance, and cost-efficient capacity at scale,” said Dan Christman, Senior Vice President of Product Management and Emerging Businesses at WD. “JetStor’s POD blueprint demonstrates how WD’s Ultrastar drives enables organizations to build a resilient, scalable data foundation that supports long-term retention and access with confidence.”
