Exos X Series — RAID & Data Protection

The Seagate Exos X 5U84 is a petabyte-scale, rack-mounted block storage system including self-healing technology, data protection options, and advanced software features.

A value-rich solution for applications that require massive capacity, performance, low latency, and dual-controller availability. Advanced features include self-healing storage, data protection options, and a full enterprise software stack offering virtual pools, thin provisioning, SSD caching, encryption, auto-tiering, snapshots, and asynchronous replication.

Product Highlights

  • Self-healing storage technology, ADAPT, and ADR
  • Deliver unfettered data access with dual redundant controllers capable of achieving superior sequential read and write performance
  • Expand a data center seamlessly with flexible SSD, HDD, and hybrid configuration options
  • Efficiently manage hot and cold data with real-time data tiering
  • Save space and maximize capacity by stacking 4 enclosures for 336 drives of data storage


Limitless data growth


Industry-first economics


Keep your data safe


Super High Capacity. Small Footprint.

Save space with up to 84 HDD or SSD devices and dual controllers all in a 5U rackmount enclosure. Connect four enclosures for a total of 336 drives.

A value-rich solution for applications that require massive capacity, performance, low latency, and always-on resiliency. Perfect mass storage for conventional data centers and cloud infrastructure.

Enterprise-Grade Platform

Ideal for storage administrators seeking massive storage capability, innovative durability, leading performance, and full featured capability along with integration and management simplicity.

A rich set of enterprise features and data protection including self-healing storage with improved Advanced Distributed Autonomic Protection Technology (ADAPT) and Autonomous Drive Regeneration (ADR), auto-tiering, snapshots, replication, and Seagate’s new ASIC-based VelosCT™ controller architecture yields extremely high-performance and high reliability.

Maximize high density potential in a 5U form factor.

For customers who need a compact solution with an ability to expand.

The ideal solution for storage administrators who want modern high-end features and the ability to massively scale with drive capacity and stackability as storage needs grow.

Reliable and Self-healing. Exos X features self-healing storage technology, Advanced Distributed Autonomic Protection Technology (ADAPT) and Autonomous Drive Regeneration (ADR). Field-proven design with five nines (99.999%) availability. Seagate ADAPT erasure code data protection software dramatically reduces array rebuild overhead. Unique Seagate ADR reduces human intervention and e-waste by automatically renewing hard drives "in situ" and on the fly.

Built for speed and resilience. Up to 2 times the performance of the previous generation with redundant active-active controllers powered by the ASIC-based VelosCT controller architecture. Streamline your overhead, with improved throughput, management, and recovery.

Easy to Set Up, Maintain, and Expand. All system components—the enclosure, the controller, the firmware, and the drives—are developed and optimized by our engineers to work together seamlessly. The modular architecture makes components interchangeable between systems, and upgrades are simple due to common FRUs, PCMs, controllers, and software.

Maximum Capacity and Consistent High Performance. Exos X 5U84 supports up to 84 drives in a single 5U enclosure with high availability and superior sequential read and write throughput. Easily expand to accommodate data proliferation by connecting up to four 5U84 enclosures together for a total of 336 drive slots.

Build In Security at the Foundation of the Data Life Cycle. Protect the most valuable business assets with Seagate Secure™ cybersecurity features and intelligent firmware —such as SFTP, SED support, and administrator access controls—that provide builtin security measures for reliable and safe file access, transfer, and management.

Improve Hardware and Administrative Efficiency and Reduce Cost. Meet stringent worldwide requirements for recycling and environmental friendliness with a nimble system that minimizes environmental impact and maximizes cost savings through high performance.
