Seagate Exos AP2U12

A space-saving, all-in-one storage server combining dual x86 compute nodes with 12 bays of high-capacity storage — a private cloud building block for small to mid-sized enterprise deployments.

2U Rackmount 12 x 3.5" LFF Bays Up to 216TB per Chassis

Overview

The Exos AP2U12 sits alongside the AP2U24 in the FUSE family — an integrated storage server with dual x86 compute nodes built into the same chassis as the storage itself, rather than a passive JBOD requiring a separate host. Where the AP2U24 favours 2.5" drive density, the AP2U12 uses 12 larger-format 3.5" bays (also compatible with 2.5" drives via a conversion carrier), prioritising capacity per drive over raw drive count.

It's built as a genuinely space-saving, all-in-one platform — a full compute-plus-storage building block that fits in a single 2U rack position, aimed at organisations building out a private cloud or consolidated storage platform without a large physical footprint.

Key Specifications

Form Factor 2U rackmount, 12 x 3.5" LFF bays (2.5" SFF supported via carrier)
Compute Dual x86 controller nodes, 2nd Gen AMD EPYC CPU (8, 12 or 16 core), one per controller
Memory Up to 4 x DDR4 DIMMs per controller, up to 256GB at up to 3200MHz
Boot Drives Single or dual M.2 NVMe SSD, redundant when dual-configured
Networking Dual-port 10/25GbE per controller, plus 2 x RJ45 dedicated management ports
Storage Controller 12G Broadcom SAS controller with dual 12Gb x4 mini-SAS HD expansion ports per node
Max Capacity Up to 216TB per chassis using 18TB drives
Power Supplies Hot-swappable, redundant, 80 PLUS Gold or Platinum options

Why Choose the AP2U12

The AP2U12's case is capacity efficiency in a compact footprint: 12 large-format drives plus dual server-grade compute nodes in a single 2U position, with up to 216TB addressable in that one chassis using current high-capacity drives. As with the AP2U24, you can right-size the compute — 8, 12 or 16-core AMD EPYC options — to match your actual workload rather than over-specifying.

A genuinely useful detail: the AP2U12 expands using Seagate's Exos E 2U12 and E 2U24 enclosures — the same JBOD expansion units behind our own EX2U12 and EX2U24 SCALE products — up to 8 chassis in a single deployment. That means you can start with a self-contained AP2U12 and grow raw capacity later using the SCALE range, without changing platform or vendor.

Dedicated management ports, hot-swappable power and cooling, and a maximum of two drive sizes per system for configuration consistency round out a platform built for straightforward, predictable operation.

Common Use Cases

  • Private cloud building blocks — Self-contained compute and storage for organisations consolidating infrastructure.
  • Small to mid-sized enterprise deployments — High-capacity storage and compute without the footprint of separate server and storage tiers.
  • Software-defined storage platforms — Running file, block or object storage stacks directly on the server itself.
  • Growing infrastructure — A starting platform that expands with SCALE enclosures as capacity needs increase.
