Reliable DAS architecture

Proven, dependable SAS technology ensures compatibility and stability.

Performance built for the pace of modern data.

Designed for high-speed and low-latency with SAS-4 connectivity.

Exos 4U74 and 4U100 leverage advanced SAS-4 architecture to deliver double the data throughput of previous SAS-3 systems — accelerating ingestion, movement, and processing across high-performance computing (HPC), AI and enterprise workloads. Built for low latency and real-time responsiveness, these systems keep pace with evolving data demands from generative AI to disaggregated storage environments. The result: faster pipelines, streamlined operations, and uncompromising performance across edge and datacentre deployments.

High-density storage for real-world data constraints.

Maximise capacity when rack space and power are limited.

Powered by Seagate’s Mozaic hard drive technology, these high-density JBOD systems enable more capacity per square metre and per watt, making them ideal for data centres and edge environments where space, power and cooling are at a premium. This balance of density and efficiency provides a future-ready foundation for AI, enterprise, and sovereign data workloads alike.

Optimized for energy efficiency from drive to chassis.

Cut power and cooling costs with smarter, greener design.

Designed for high-density deployments, Exos 4U74 and 4U100 integrate intelligent cooling, optimised airflow, and dynamic fan control to deliver up to 70% better thermal efficiency and 30% lower power consumption than legacy enclosures. But efficiency doesn’t stop at the chassis — each system is built to harness the energy-saving advantages of Mozaic hard drives, delivering sustainable, large-scale storage with reduced operational costs and environmental impact.

Vibration dampening for enhanced reliability.

Exos 4U74 and 4U100 integrate next-generation vibration mitigation technology that ensures consistent performance and drive longevity in dense environments. Minimising mechanical resonance and acoustic interference, they protect sensitive components and maintain optimal throughput under heavy workloads — ideal for AI/ML pipelines and edge deployments.

Ready for what comes next.

Seagate’s Mozaic hard drives with 50 TB and beyond are on the horizon — and these JBODs are engineered to meet their full potential.

That means an unmatched foundation for scalable, energy-efficient storage. Whether managing generative AI workloads, HPC simulations, or massive unstructured datasets, these systems ensure long-term scalability without disruptive infrastructure overhauls, keeping your data architecture future-ready.

On-prem control with proven, reliable architecture.

With a trusted SAS-based DAS architecture, Exos 4U74 and 4U100 deliver the reliability and low-latency performance required for regulated and mission-critical workloads. These systems support hybrid drive configurations and integrate seamlessly into existing infrastructure, offering data sovereignty, compliance and peace of mind — all while simplifying deployment and maintenance.
