Huawei invests heavily in storage R&D, with over $2 billion and 3,200 R&D engineers developing their proprietary OceanStor operating system and Huawei-developed SSDs (HSSDs). Their dedicated flash-optimized OS, algorithms and HSSDs enable Huawei's all-flash storage to deliver the highest performance and reliability in the industry. As the core of Huawei's software and hardware, OceanStor and HSSDs are strategically important. Through in-house development rather than acquisitions, Huawei can ensure better integration and collaboration between its storage products.
