What are Exos PROTECT systems?
When data can’t go down, Exos PROTECT systems deliver built‑in redundancy, reliability and hybrid‑ready protection for regulated, always‑on workloads.
Exos PROTECT arrays are petabyte-scale, rack-mounted block storage systems that include self-healing technology, advanced data protection and a full software stack. Essential software features include auto-tiering, Snapshots, asynchronous replication and virtual pools.
Seagate’s 7th generation controller architecture yields long-term storage reliability, and the best value for performance and cost.
Enterprise-grade reliability with end-to-end data protection reduces downtime with rapid recovery and failover capabilities, while advanced encryption and security controls protect critical data and the platform scales seamlessly to meet growing backup and archival needs.
What makes Exos PROTECT different from a standard RAID array?
Six commitments carry across every PROTECT array — the qualities that make it the Exos family for workloads that cannot stop.
Availability Assured
Self-healing technology, redundant hot-swappable controllers, drives, fans and power supplies with automatic failover and dual-path support.
Protection Enforced
Advanced distributed autonomic protection technology (ADAPT), NRAID and RAID 0, 1, 5, 6 and 10 with drive-level encryption.
Performance Consistent
Low latency block and file access with accelerated system performance for storage networks and direct storage applications.
Recovery Accelerated
Reduces downtime with rapid recovery and failover capabilities so continuity and recovery objectives are met.
Reliability Proven
Seagate’s vertical integration means we build the drives, storage controllers and chassis — with best-in-class design and thorough testing.
Compliance Built In
Advanced encryption and security controls to protect critical data across regulated and always-on environments.
How does ADAPT distributed data protection rebuild a failed drive?
ADAPT is Seagate’s advanced distributed autonomic protection technology, included across the Exos PROTECT family.
Rather than dedicating whole drives as spares, ADAPT distributes spare capacity across every drive in the pool. When a drive fails, the array rebuilds only the data that was actually written — in parallel, across many drives at once — instead of rewriting an entire replacement disk.
Combined with redundant hot-swappable controllers, drives, fans and power supplies with automatic failover and dual-path support, this is what lets Exos PROTECT nearly eliminate downtime and maximize availability.
Essential software features round out the stack: virtual or linear pools, thin provisioning, SSD read cache, encryption, auto-tiering, Snapshots and asynchronous replication.
How do the three Exos PROTECT arrays compare?
Three dual-controller block storage platforms — 12, 24 or 84 drive slots, all with the same enterprise software stack.
Utmost density for maximum capacity, availability, versatility and performance. Expands to 336 drives.

Exos PROTECT systems: frequently asked questions
Redundancy, ADAPT, connectivity and procurement answers for the Exos PROTECT array family.
When data can’t go down, Exos PROTECT systems deliver built-in redundancy, reliability and hybrid-ready protection for regulated, always-on workloads. They are petabyte-scale, rack-mounted block storage systems that include self-healing technology, advanced data protection and a full software stack.
Three arrays: Exos PROTECT EP2U12 (2U, 12 drive slots), EP2U24 (2U, 24 small form factor drive slots) and EP5U84 (5U, 84 drive slots). EP2U12 and EP2U24 each connect up to nine expansion enclosures; EP5U84 connects three, for a maximum of 336 drives.
ADAPT is advanced distributed autonomic protection technology, included across the Exos PROTECT family. It distributes spare capacity across every drive in the pool and rebuilds only the data that was actually written, in parallel across many drives — delivering far faster recovery than a conventional dedicated-spare RAID rebuild. Improved ADAPT, NRAID and RAID 0, 1, 5, 6 and 10 are all supported.
Essential software features include virtual or linear pools, thin provisioning, SSD read cache, encryption, auto-tiering, Snapshots and asynchronous replication. Seagate’s 7th generation controller architecture yields long-term storage reliability and the best value for performance and cost.
Every PROTECT array provides four host ports per controller and eight per system, using SFP+ / SFP28 or mini-SAS HD. Supported host connectivity is 12Gb SAS, 32/16Gb Fibre Channel, 25/10GbE iSCSI and 10GBASE-T auto-negotiating down to 1Gb.
Through self-healing technology plus redundant hot-swappable controllers, drives, fans and power supplies with automatic failover and dual-path support. Seagate redundancy and self-healing technology delivers on continuity and recovery objectives, nearly eliminating downtime and maximizing availability.
Yes. The arrays support flexible hard drive configurations for a limited budget as well as hybrid flash configuration options, with SSD read cache and optional auto-tiering to place hot data on flash automatically.
