Huawei OceanStor Dorado 5000 All-Flash Storage
Mid-range NVMe all-flash storage for mission-critical enterprise services
The Huawei OceanStor Dorado 5000 is a mid-range all-flash storage system built on an end-to-end NVMe architecture and Huawei’s FlashLink intelligent algorithms. Designed for always-on enterprise services, it combines 0.05 ms latency with linear scale-out to 32 controllers, unified SAN and NAS, and a five-layer reliability design.
Key features
End-to-end NVMe
Front-end 32G FC-NVMe and 100G NVMe over RoCE, back-end 100G RDMA and NVMe SSDs deliver latency as low as 0.05 ms.
FlashLink algorithms
Huawei’s self-developed FlashLink separates data and control flows and coordinates controllers with SSDs for stable, predictable performance.
Scale-out to 32 controllers
A single system scales from two to 32 controllers. IOPS and capacity grow linearly as controller enclosures are added.
RAID-TP triple parity
Triple-paracity protection tolerates three simultaneous SSD failures, and a smart SSD enclosure reconstructs 1 TB in about 25 minutes.
Unified SAN and NAS
Block and file services run on the same controllers with parallel access, plus object (S3) support for modern applications.
Always-on five-layer reliability
Component, architecture, product, solution and cloud layers target 99.9999% availability with gateway-free active-active for SAN and NAS.
Typical use cases
Mission-critical databases
OLTP and OLAP databases, ERP and core transaction systems that demand consistent low latency and continuous availability.
Server virtualization & VDI
Large virtualized data stores and virtual desktop fleets consolidated on high-density all-flash storage.
Resource consolidation
Consolidate SAN, NAS and heterogeneous arrays behind a single, intelligent management plane.
Why enterprises choose the Dorado 5000
The Dorado 5000 sits at the center of Huawei’s all-flash lineup. Unlike arrays that add NVMe only at the front end, it uses NVMe across the whole data path: 32G FC-NVMe and 100G RoCE connect hosts, while 100G RDMA links controllers to NVMe SSDs. Combined with FlashLink, that design keeps latency stable at around 0.05 ms even when the system is heavily loaded.
The system also removes the trade-off between scale and resilience. Adding controllers increases IOPS and cache in a straight line, and the fully symmetric active-active architecture lets every controller serve every LUN. With RAID-TP, smart-SSD reconstruction and gateway-free HyperMetro for SAN and NAS, the five-layer reliability design targets 99.9999% availability.
For IT teams modernizing legacy storage, SmartVirtualization allows existing third-party arrays to be taken over behind one management plane, and FlashEver supports component-based upgrades without a forced data migration. The result is an all-flash platform that can stay current across multiple hardware generations.

Frequently asked questions
What is the Huawei OceanStor Dorado 5000?
It is a mid-range, end-to-end NVMe all-flash storage array designed for mission-critical enterprise workloads such as OLTP/OLAP databases, virtualization, VDI and resource consolidation.
How many controllers does the Dorado 5000 support?
It scales from two controllers up to 32 controllers in a fully symmetric active-active design, with performance and capacity growing linearly.
How much cache does the Dorado 5000 provide?
With dual controllers the system provides 256 GB to 8 TB of cache, expanding as more controllers are added.
What is the latency of the Dorado 5000?
Thanks to end-to-end NVMe and 100G RDMA, latency can be as low as 0.05 ms.
What SSD types are supported?
It supports 1.92/3.84/7.68 TB palm-sized NVMe SSDs and 960 GB to 15.36 TB SAS SSDs, with capacity-optimized and encrypted NVMe options.
How many SSDs can one system hold?
A Dorado 5000 can scale to up to 3,200 SSDs.
What protocols does it support?
FC, iSCSI, NFS, CIFS, FC-NVMe, NVMe over RoCE, NDMP and S3 are supported on unified controllers.
What is RAID-TP?
RAID-TP is Huawei’s triple-parity RAID level that keeps the system running if three SSDs fail at the same time.
How fast is reconstruction?
A smart SSD enclosure can reconstruct about 1 TB of data within 25 minutes.
