No.1 Performance with Chip-Powered Architectures

Smart to the Core: Five Built-in Intelligent Chips

OceanStor Dorado benefits from five, built-in, proprietary Huawei intelligent chips to implement an end-to-end service acceleration platform that triples performance and maximizes resource utilization.

  • Multi-protocol Interface Chip
  • BMC Management Chip
  • SSD Controller Chip
  • Intelligent Processor Chip
  • Intelligent AI Chip
  • Kunpeng 920 Chip

    The intelligent processor chip uses an ARM-based CPU that offers the industry's highest performance: 25% more computing power than the next-best.


    higher than the industry benchmark

  • Ascend AI Chip

    Based on machine learning frameworks, the intelligent AI chip actively analyzes and understands I/O rules of multiple application models, implements intelligent prefetch of memory space, improves the read cache hit ratio by 50%, and shortens batch processing latency from 300μs to 150μs.


    higher read cache hit ratio

  • Intelligent
    Multi-protocol Interface Chip

    The chip intelligently parses front-end protocols — including 32 Gbit/s Fiber Channel and 100 GE, with forward compatibility — improving storage performance by 20%.


    better storage performance

  • SSD Controller Chip

    The chip implements the Flash Translation Layer (FTL) in silicon to accelerate data access in SSDs, reducing read latency by 80 μs, 10% lower than the nearest competitor.

    0 μs

  • BMC Management Chip

    Implementing intelligent and comprehensive fault management, the chip provides fault location accuracy of up to 93%, slashing fault recovery times from two hours to just ten minutes.

The Fast Path: NVMe Architecture

Huawei makes the most of NVMe protocols with the industry’s only end-to-end development of an NVMe flash controller, NVMe all-flash Operating System (OS), and NVMe SSDs. Powered by this NVMe architecture, with finely tuned disk/controller coordination, Huawei’s NVMe all-flash storage now offers stable latency of 0.1 milliseconds.

  • End-to-End NVMe Architecture

    Implements direct communication between the CPU and SSDs.

99.9999% Field-Proven Availability

Component reliability

Huawei SSD

An integrated range of technologies prolongs service life, including Low-Density Parity-Check (LDPC) code error correction, global wear leveling, anti-wear leveling, and flash-ice heat dissipation. With a Mean Time Between Failures (MTBF) of three million hours, Huawei SSD reliability leads the industry.

Product reliability

RAID-TP Technology

Three simultaneous disk failures are tolerated without interrupting services.

Reduces the time to reconstruct 1 TB of data from five hours to just 30 minutes.

Traditional RAID

0 hours

Solution reliability

HyperMetro Gateway-Free Active-Active Solution

With load balanced between active-active mirrors, non-disruptive cross-site takeover is permitted. The gateway-free design simplifies deployment and reduces the number of possible points of failure. The solution can smoothly upgrade to three data centers without gateways, achieving 99.9999% availability.

Cloud reliability

Converged Data Management

Providing industry-leading self-protection for storage in a multi-cloud environment, the system unifies management of disaster recovery, backup, and data reuse.


Low OPEX with AI-Powered O&M
