OceanStor Dorado V6 All-Flash Storage Systems

Huawei OceanStor Dorado V6 all-flash enterprise storage systems are designed for mission-critical services.

Employing a next generation hardware platform, reliable SmartMatrix architecture, five intelligent chips, Non-Volatile Memory Express (NVMe) and Serial Attached SCSI (SAS) Solid State Drives (SSDs), and the FlashLink® intelligent algorithm, OceanStor Dorado V6 is the first full series storage that supports end-to-end NVMe architecture, delivering industry-leading performance — of up to 21 million Input/Output Operations Per Second (SPC-1 IOPSTM)* — allied with extreme reliability: Dorado V6 effectively prevents any service interruptions, offering fault detection systems that never affect services, and with no waiting time during upgrades.

Customized intelligent device training and the eService platform achieve intelligent lifecycle management, from resource provisioning to fault locating. Dorado V6 fully supports intelligent and elastic architecture to build an industry-leading intelligent Operations and Maintenance (O&M) system.

Huawei OceanStor Dorado V6 all-flash storage systems satisfy the data hungry storage requirements of large databases, particularly in the carrier, finance, government, and manufacturing industries.

Performance with Chip-Powered Architectures

No. 1 Performance with Chip-Powered Architectures

Dorado V6 offers industry-leading performance of 21 million SPC-1 IOPS TM — twice that of competitor products — and just 0.05 ms latency, with an end-to-end high-speed platform developed from the chips up. The FlashLink® intelligent algorithm combined with 32 controllers offers powerful scalability that expedites enterprise transformation toward the all-flash era.

  1. Up to 21,000,000 SPC-1 IOPS TM
  2. Down to 0.05 ms latency
Industry-leading reliability with SmartMatrix architecture, for always-on applications

Always-On Applications with SmartMatrix

Empowered by an intelligent balancing algorithm and a self-developed convergent network chip, SmartMatrix architecture tolerates the collective failure of 7 out of 8 controllers across engines without causing service interruptions — a capability that no other vendor can provide.

  1. Zero interruption on applications Toleration of the failure of 7 out of 8 controllers across engines without disrupting services.
  2. Faults rectified immediately Only one second switchover with uninterrupted links in the event of controller failure.
  3. Zero impact during upgrades Single second online upgrades with no impact on host services.
AI-powered full-lifecycle management, no data migration

Efficient O&M with Edge-Cloud AI Synergy

With the transition to all flash-oriented architecture, enterprises can boost IT efficiencies to increase profits while achieving intelligent O&M and delivering optimal user experience.

  1. Edge-cloud synergy Built-in AI chips are used for incremental training and deep learning of service characteristics, enhancing personalized customer experience.
  2. AI throughout service lifecycle Sixty day prediction of performance and capacity trends, 14-day prediction of disk faults, and immediate solutions for 93% of problems located.
  3. FLASH EVER program Next generation software and hardware capabilities help make the most of existing investments.
