Description

The Huawei OceanStor Dorado 5000 V6 is a next-generation all-flash storage system designed for mission-critical enterprise workloads. Its architecture delivers ultra-low latency, high throughput, and robust availability via dual controllers, NVMe over RDMA front-ends, and advanced data services. Official specifications show latency as low as **0.05 ms**, with full end-to-end NVMe support. 

Your configuration includes 66 × 7.68 TB NVMe SSDs + 2 × ultra-fast M.2 NVMe SSDs (for boot/cache), housed in a Palm form factor NVMe enclosure, plus a 36-slot NVMe disk enclosure for expansion. With 512 GB of cache and redundant dual controllers in a 2U head unit, this system can handle very high I/O demands. 

On network and I/O side, this build features 4 SmartIO modules (SFP+ / 16 Gb FC), plus front-end ports capable of 100 Gb RDMA, together with fiber cables and passive QSFP28 links for high bandwidth connectivity. It’s well-suited to environments needing fast block or file storage over SAN/NVMe-RoCE infrastructure.

The system is configured with capacity to expand: a 36-slot NVMe enclosure is included, ready for future disk growth, as well as software licenses for advanced data services such as snapshots, cloning, replication, thin provisioning, dedupe/compression, QoS, Metro / CDP etc. 

With a one-year remote support contract, hot-swappable components, and enterprise reliability, this setup is designed to deliver performance and uptime for critical enterprise processes, data analytics, virtualization, or high-transaction databases. Rails / enclosures make installation into racks manageable and maintenance easier.

Key Features

  • All-NVMe architecture: Primary storage using 7.68 TB palm-sized NVMe SSDs, plus M.2 NVMe devices for cache or boot.
  • High I/O protocol support: Front-end 100 Gb RDMA, 16 Gbit FC via SmartIO modules, fiber cable/optics included.
  • 512 GB cache in dual controllers in a 2U head unit with redundancy and high availability.
  • Expansive hot-swappable NVMe disk enclosure (36-slot) for future scale-out without downtime.
  • Rich software suite: SmartDedupe & Compression, Thin provisioning, Snapshots, Replication, Clone, QoS, Metro, CDP, etc.
  • High performance & low latency: E2E NVMe, FlashLink® intelligent algorithms, latency down to ~0.05 ms. 
  • Robust reliability: Multi-controller setup, hot-swap components, redundant design, multiple layers of fault tolerance.
  • Strong connectivity: fiber cables, QSFP28 high speed passive links, optical modules, proper network front-end alignment.

Compatibility

The Dorado 5000 V6 supports a wide range of NVMe SSD sizes (1.92 TB, 3.84 TB, 7.68 TB, 15.36 TB, etc.) including palm-sized NVMe units. 

Front-end protocols supported include FC, FC-NVMe, iSCSI, RDMA / NVMe-over-RoCE, NFS / CIFS / NFS over RDMA; Back-end connectivity via high speed RDMA / SAS etc. 

Controller enclosures can support multiple I/O modules and expansion enclosures; your 36-slot NVMe enclosure is fully compatible. System offers multiple levels of RAID, including RAID-5/6/10 and RAID-TP (which tolerates 3-SSD failures). :

Usage Scenarios

High-Transaction Databases & OLTP — The low latency and high IOPS make this ideal for databases that need fast reads/writes, small block performance, and consistent SLA.

Analytics & AI / ML — Large SSD count plus NVMe speed help feed data pipelines, ML inference, or real-time analytics efficiently.

Virtualization & VDI Pools — Use SSDs as fast storage tier, snapshots / clones for view backups, and replication for resilience.

Hybrid SAN / NAS Services — The system supports both block (FC, iSCSI) and file (NAS) protocols; can serve mixed workloads with data efficiency features (dedupe/compression etc.).

Disaster Recovery & High Availability — With Super-Advanced license, Metro / CDP, snapshots & replication, this can be part of an HA or DR solution across sites.

Frequently Asked Questions

Q1: What is the typical latency under load?
A: With full NVMe + RDMA front-ends and cache enabled, Dorado 5000 V6 systems can achieve around **0.05 ms** latency in ideal conditions.


Q2: How many SSDs failures can it tolerate without downtime?
A: Using RAID-TP configuration, the system can tolerate up to **3 SSD failures** in a RAID group without loss of data or service disruption.


Q3: Is the system ready for both SAN and NAS protocols?
A: Yes. It supports FC, FC-NVMe, iSCSI for block storage, and NFS / CIFS / NAS over RDMA for file storage. Mixed protocol usage is common.


Q4: What software features are included and required for full functionality?
A: To unlock full enterprise features—snapshots, replication, compression, Metro network DR, etc.—you’ll need the advanced licensing (Super-Advanced License etc.), which you have included. Basic DeviceManager, Thin provisioning, etc. are often standard.
