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.
