Uncompromising
Performance in Different Scenarios

Competitor vs. Huawei storage performance after value-added features are successively enabled

Competitor AFA: 40% lower; Huawei AFA: <10% lower

  • Test devices: Dual-controller, 1 TB cache, 16G FC frontend, NVMe backend, 25 x 3.84 TB SSDs
  • Test conditions: Hybrid workload, 8K I/Os, 7:3 read/write, 1 ms average latency, 8 LUNs

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 0.05 milliseconds.

The Secret Weapon: FlashLink Algorithms

OceanStor Dorado’s new, SSD-optimized design and disk/controller coordination technology enable storage controllers to detect data layouts in SSDs in real time, synchronizing the data in controllers and SSDs. Such coordination helps reduce performance losses caused by garbage collection and ensures rapid response to data read and write I/Os.
