SOLUTION

Slide
Artificial Intelligence
In AI scenarios, model training, inference, and massive data preprocessing impose extremely high demands on storage IOPS, bandwidth, and latency. DERA NVMe SSDs deliver outstanding random read/write performance, high stability, and consistency, fully meeting the requirements of various AI workloads.
Case1.2
Cloud Computing
Enterprise SSDs provide efficient and stable storage support for cloud computing with advantages such as ultra-high-speed read/write, high reliability & low latency, high energy efficiency & low power consumption, flexible elastic expansion, and end-to-end data security protection. These significantly enhance resource utilization efficiency and reduce operating costs.

RELATED CASES

During peak promotions like "11.11" and "618", an e-commerce platform faced massive pressure on its cloud systems. Leveraging deep expertise in cloud databases and astute insights into SSD development trends, the company chose DERA NVMe SSDs to boost performance. With the close on-site collaboration of DERA's technical team, the platform ensured stable and reliable operation of its cloud storage system.

  • Challenge

    High concurrency and extreme workloads | Urgent need to improve data access efficiency | Pressing demand for system performance enhancement

  • Solution

    DERA collaborated with the client on a development partnership, leveraging Open-Channel technology to migrate key SSD modules to the host side. This enabled deep custom hardware-software integration of the storage system, allowing for true workload-specific design and optimization tailored to different business load characteristics.

  • Benefits

    As an independent storage engine, the Open-Channel project (paired with RDS) has successfully integrated with multiple critical business lines. It achieves performance improvements that surpass what can be attained by solely enhancing storage performance or optimizing software logic in peer-grade products.
