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

JetStor announced the successful deployment of an 80PB high-density archive for a government agency – one of its largest on-premises archive deployments of its kind in the public sector.Designed to meet rigorous security demands for long-term data retention, JetStor’s POD-based architecture was paired with WD Ultrastar 26TB enterprise-class hard drives to deliver a secure, high-density cost-efficient storage foundation built for long-term data retention at scale.

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 26TB SAS 7,200rpm 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. We standardized the deployment into repeatable POD building blocks and paired them with WD 26TB Ultrastar drives to deliver an active archive that scales cleanly, stays isolated on Fibre Channel, and remains straightforward to operate,” said Gene Leyzarovich, Founder, JetStor.

“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. 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,” said Dan Christman, SVP, product management and emerging businesses, WD.
