Exos X 2U12 Advanced Storage Array

Seagate Exos X advanced storage array is a petabyte-scale, rack-mounted block storage enclosure with self-healing technology, advanced data protection, and software value delivering superefficient mass-capacity storage for conventional data centers and cloud infrastructure.

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 10 Enclosures for 120 drives of data storage


Limitless data growth


Industry-first economics


Keep your data safe


High Capacity. Small Footprint

Save space with up to 12 SSD or HDD drives and dual controllers all in a 2U rackmount enclosure. Connect 10 enclosures for a total of 120 drives.

The ideal storage solution for emerging customers who need larger data storage at the greatest space utilization with modern technology, high-capacity drives, and lower power consumption.

Enterprise-Grade Platform

The standard for storage administrators seeking petabyte capability in a 2U form factor, frictionless integration, advanced features, and data protection options along with 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.

Ultimate Availability

Self-healing technology, redundant hot-swap controllers, drives, fans, and power supplies, dual power cords, hot standby spare, automatic failover, and multi-path support.

The finest solution for storage administrators who want modern high-end features, drive resiliency, and the ability to nearly eliminate downtime and maximize availability. Seagate redundancy and self-healing technology deliver on continuity and recovery objectives.

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.

Gain and Scale Capacity with Consistent High Performance. The Exos X 2U12 enables even the smallest business with maximum speed and throughput. Additionally, businesses can expand the system as data requirements grow, with 12 drive slots of storage capacity in a 2U rackmount enclosure. Connect up to ten 2U12 enclosures together for a total of 120 drive slots.

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 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.
