Huawei OceanStor Storage Systems
Dorado all-flash, hybrid flash and Pacific distributed scale-out storage for mission-critical enterprise workloads.
The Huawei OceanStor portfolio covers the full range of enterprise data storage, from end-to-end NVMe all-flash arrays to cost-effective hybrid flash systems and massively scalable distributed storage. This guide compares the families we configure and supply most often, with links to full specifications for each model.
OceanStor storage families
OceanStor Dorado 5000
End-to-end NVMe all-flash array with FlashLink, 0.05 ms latency and scale-out to 32 controllers for mission-critical workloads.
OceanStor 5310
Hybrid flash storage that mixes NVMe/SAS SSDs with high-capacity disks, scales to 16 controllers and converges block, file and object.
OceanStor Pacific 9546
High-density 4U scale-out appliance with up to 1,440 TB raw capacity per chassis for HPC, big data, backup and archives.
A storage platform for every data profile
Enterprise data is rarely uniform. A core banking or ERP system needs the lowest possible latency and six-nines availability; a general-purpose data center needs flexible, tiered capacity; and a backup, media or research environment needs to store petabytes economically and access them over file and object protocols. OceanStor addresses each profile within one product family, so storage can be selected by workload while sharing common management, data services and disaster-recovery concepts.
Across the portfolio, the same design principles recur: symmetric active-active controllers, flash-aware algorithms, triple-parity or erasure-coded protection, gateway-free active-active and built-in ransomware defenses. That consistency makes it practical to standardize on OceanStor across tiers, from the highest-performance production array to the densest capacity node.
Architecture and platform
End-to-end NVMe
OceanStor systems carry NVMe from the host fabric through controllers to SSDs, replacing SCSI queues with tens of thousands of parallel queues for 0.05 ms latency.
Multi-controller active-active
Controllers operate in fully symmetric designs so that any controller can serve every volume or file system, eliminating single points of control.
Distributed scale-out
Pacific nodes scale in balanced clusters with data and performance growing together across a single namespace.
Kunpeng & palm-sized SSDs
Huawei Kunpeng processors and palm-sized NVMe SSDs deliver high compute and cache density in a compact, efficient footprint.
Software and data services
Data protection
HyperMetro gateway-free active-active, HyperCDP continuous data protection, SmartMigration, remote replication and 3DC/4DC disaster recovery.
Data reduction
SmartDedupe, SmartCompression, thin provisioning, automatic tiering and RAID-TP triple parity for efficiency and resilience.
Security & O&M
HyperEncryption, HyperLock WORM, air-gap ransomware copies, DeviceManager, DME and eService for intelligent cloud operations.

How to choose an OceanStor system
Choose Dorado 5000
Lowest latency for core databases. When sub-millisecond response, consistent IOPS and maximum controller scale matter most, an end-to-end NVMe all-flash array is the right answer.
Choose OceanStor 5310
Best balance of performance and cost. For mixed workloads where hot data needs flash but bulk data can live on high-capacity disks, hybrid flash delivers strong value.
Choose Pacific 9546
Massive unstructured data growth. When capacity is measured in petabytes and access is file, object or HDFS, distributed scale-out provides density and a single namespace.
Choose Dorado 5000 or 5310
Consolidation of block and file. Both unified arrays serve SAN and NAS from the same controllers, reducing the number of systems to manage.

Which OceanStor families do you supply?
We configure and supply the Dorado 5000 all-flash array, the OceanStor 5310 hybrid flash system and the Pacific 9546 scale-out appliance, along with related expansion and networking options.
What is the difference between Dorado and the 5000 hybrid flash series?
Dorado is an end-to-end NVMe all-flash array for the lowest latency, while the hybrid flash 5000 series combines SSDs with high-capacity disks to balance performance and cost.
What is OceanStor Pacific used for?
Pacific is a distributed, scale-out platform for mass unstructured data such as HPC, big-data analytics, video repositories, backup and long-term archiving.
How much can a Dorado 5000 scale?
A single Dorado 5000 scales to 32 controllers, up to 8 TB dual-controller cache and up to 3,200 SSDs.
