In today’s competitive business environment, IT organisations need to provide a high-quality and productive IT environment for continuously growing internal users and external customers. In addition, enterprise application environments have become increasingly unpredictable as their IT infrastructure requirements grow in complexity and size.

“Mission-critical business application performance is highly sensitive to storage performance and latency, and highly dependent on the resilience of the enterprise IT environment,” observes Walid Gomaa, VP, Data Centre & Cloud Solutions, Middle East Enterprise Business Group, Huawei.

Huawei OceanStor Dorado V3 fully satisfies the high performance and resilience requirements of mission-critical business applications. It helps customers in finance, manufacturing, telecom, and other sectors to enhance their database services and virtualisation environments with the best Total Cost of Ownership (TCO), Gomaa observes.


The OceanStor Dorado V3 all-flash storage is able to deliver 0.5 ms consistent latency by incorporating intelligent chips, NVMe architectures, and Huawei’s FlashLink intelligent algorithms to achieve end-to-end optimisations from SSDs and controllers, which help improve the application performance threefold.

The OceanStor Dorado V3 can scale out to 16 controllers and can reach 7 million IOPS, which makes it the World’s Fastest All Flash Storage according to the latest SPC-1 report

System architecture

OceanStor Dorado V3 all-flash storage systems use Huawei OceanStor OS as the operating system and inherit abundant features of the operating system. The SSDs of the storage systems have been optimised to deliver optimal performance at a cost-effective price.

In addition, the storage systems are able to support various host ports such as Fibre Channel ports, Ethernet iSCSI ports, as well as high-speed low-latency InfiniBand (IB) ports.

The scale-out technology adopted by the platform expands the number of controller enclosures to ensure linear growth of capacity and performance at a stable low latency whereas the scale-up technology adds disk enclosures and disks to expand the capacity. When the capacity increases, the back-end data balancing mechanism automatically balances data among all disks.

Key features

Key characteristics include an outstanding performance that provides seven million IOPS, 0.5 ms consistent low latency, improving application performance by 3x.

Huawei’s OceanStor Dorado V3 is already distinguishing itself in the industry for its stability and reliability by adopting abundant end-to-end reliability technologies. The gateway-free active-active solution can deliver 99.9999% business availability.

In addition, it can be smoothly upgraded to 3DC solution. Additionally, the inline data reduction technologies (inline deduplication and compression) can achieve 3:1 data reduction ratio and enable enterprises to reduce OPEX by 75%.

OceanStor Dorado V3 has wide compatibility and is compatible with over 300 mainstream storage systems and 98% of IT infrastructures, enabling smooth upgrades that do not affect business and help data centers transition easily to flash.

Industry accolades

DCIG evaluated 32 mainstream All-Flash Arrays (AFAs) and gave the Huawei OceanStor Dorado the Highest Recommended Ranking based on performance, management, software, hardware, virtualisation, and technical support.

ESG Lab performed hands-on testing of the OceanStor Dorado V3 all-flash storage. Their five-year TCO analysis highlights the system’s financial advantages over hybrid and first-generation all-flash storage systems from major vendors.
