3x Increase in Application Performance

Core at the Core: Purpose-Built Chips

OceanStor Dorado V3 uses Huawei’s intelligent multi-protocol interface chip, intelligent SSD controller chip, and intelligent BMC management chip 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 Multi-protocol Interface Chip

    Intelligently parses front-end protocols including 32 Gbit/s Fiber Channel and 100 GE protocols with forward compatibility. This module improves storage performance by 20%.


    storage performance

  • SSD Controller Chip

    Implements Flash Translation Layer (FTL) in silicon to accelerate data access in SSDs. This Huawei chip reduces read latency by 80 μs, 10% lower than the runner up.

    0 μs

  • BMC Management Chip

    Implements intelligent and comprehensive fault management. Fault location accuracy is up to 93%, shortening fault recovery times from 2 hours to 10 minutes.

The Fast Path: NVMe Architecture

Huawei is taking full advantage of NVMe protocols with the industry’s only end-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 ensures a stable latency of 0.5 milliseconds.


99.9999% Field-proven Availability

Component reliability

Huawei SSD

Integrates a range of technologies to prolong service life, including Low-Density Parity-Check Code (LDPC) error correction, global wear leveling, anti-wear leveling, and flash-ice heat dissipation. With a Mean Time Between Failures (MTBF) of 3 million hours, our SSD reliability is No. 1 in the industry.

Product reliability

RAID-TP Technology

Tolerates three simultaneous disk failures without interrupting services.

Reduces the time to reconstruct 1 TB of data from 5 hours to 0.5 hours.

Traditional RAID

0 hours


0 hours
Solution reliability

HyperMetro Gateway-free Active-active Solution

Balances the load between active-active mirrors and permits non-disruptive cross-site takeover. 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 to achieve 99.9999% availability.

Cloud reliability

Converged Data Management

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


75% OPEX Savings

Data Reduction: Inline Compression and De-duplication

Greatly reduces the storage footprint while maintaining high performance. OceanStor Dorado V3 offers a data reduction ratio as high as 5:1.
