The DAE22525U2-1-DC is a 2U, DC-powered expansion module for Huawei OceanStor storage systems, offering 25 hot-swappable 2.5″ drive slots without preinstalled disks.
The enclosure provides 25 front-loading 2.5″ drive bays compatible with SAS, SATA and SSD media.
No. It ships diskless so you can populate it with your choice of Huawei-qualified SAS, SATA or SSD drives.
It supports enterprise-grade 2.5″ SAS, SATA and solid-state drives certified by Huawei.
Yes. All 25 drives are fully hot-swappable, allowing you to add or replace disks without powering down the system.
It uses dual redundant -48 V DC power modules for high availability and continuous operation.
The enclosure measures 482.6 mm (W) × 740 mm (D) × 88.6 mm (H), fitting a standard 19″, 2U rack mount.
Use the rear SAS 12 Gbps expansion ports to link directly to OceanStor controller SAS ports or expansion modules.
Although technically possible, Huawei recommends using uniform drive types within an enclosure for optimal performance and reliability.
Manage the enclosure via Huawei DeviceManager or the OceanStor management GUI, providing health monitoring and firmware updates.
It operates reliably at 0 °C to 45 °C, 5%–95% non-condensing humidity, and up to 3 000 m altitude.
Capacity depends on installed drives; for example, equipping 20 TB SSDs yields up to 500 TB of raw storage.
You can cascade up to 8 of these enclosures per OceanStor controller cluster for large-scale expansion.
Huawei provides a standard 3-year limited hardware warranty, with optional service extensions available.
Mount the enclosure on a 19″ rack using the supplied rail kit, connect DC power and SAS cables, then initialize it via the management interface.
