Nvidia开源的Dynamo项目，实现存储系统多级缓存算法，热数据在显存、温数据在主机内存、冷数据在 SSD 或远端对象存储，并通过一套 统一的索引 + 异步流水线实现自动迁移与透明访问，但是多级存储之间的数据迁移流程复杂，延迟开销难以压缩。 微软推出的LMCahce存储系统，高度兼容vLLM等推理框架，但是对分布式存储支持较低，空间上限低。 阿里巴巴提出一种将KV Cache空间扩展到Tair数据库的远端存储方案，存储空间易扩展，但是读写性能难以满足LLM推理业务的低延迟需 求。 CXL（Compute Express Link） 作为一种新兴的高速互联技术，以其高带宽、低延迟和硬件级缓存一致性的特性，为破解内存瓶颈带来了 新的希望，可以解决AI和高性能计算中遇到的内存瓶颈问题。 业界关于CXL存储加速LLM推理的研究仍然较少，探索如何利用CXL等新型介质扩展KV Cache空间，进而将成熟的软件栈迁移到CXL硬件场 景，是一项非常有意义的工作。 当大语言模型（LLM）走向千行百业，推理效率与显存成本的矛盾日益尖锐。 KV Cache （Key-Value Cache）作为提升生成速度的核心技术，却像一个 ...

Investment Strategy - Concerns over Nvidia's security may accelerate the replacement of domestic chips, creating a vacuum in the supply of computing chips in China. Recent advancements in domestic computing cards are expected to drive rapid development in the related industry chain. Nvidia's H20 computing chip has been reported to have serious security issues, which could negatively impact its future orders in the Chinese market. In 2024, over 50% of the data center accelerator cards in China are expected to be inference cards, with domestic computing cards projected to account for over 40% by the first half of 2025. The domestic accelerated computing server market is expected to grow by 97.3% year-on-year in 2024 and by 52.9% in 2025 [10][12][13] - The release of DeepSeek-V3.1 is expected to enhance the usability of domestic computing cards in large model applications. The V3.1 version supports UE8M0 FP8 precision, which significantly reduces storage and improves computational throughput compared to traditional FP16 and FP32 formats. This advancement is anticipated to lead to a qualitative leap in the application of domestic computing cards [11][14] - The demand for computing infrastructure from operators and cloud vendors is clear, with capital expenditures expected to increase in the second half of the year. The three major operators reported good growth in computing-related business revenues, with China Telecom's cloud service revenue at 57.3 billion yuan, China Unicom's at 37.6 billion yuan, and China Mobile's at 56.1 billion yuan. Capital expenditures for the first half of 2025 are projected to be 494 billion yuan for China Telecom, 348 billion yuan for China Unicom, and 928 billion yuan for China Mobile, accounting for 59.1%, 63.3%, and 61.4% of their annual expenditures respectively [12][13][18] Industry News - The successful launch of the low-orbit satellite internet 09 group marks a significant step in China's satellite internet development, with the country entering a high-density launch phase. This mission was the 590th flight of the Long March series of rockets, and it is expected to enhance the satellite internet network [15][16] - The budget for the 2025 rocket launch service procurement project by Shanghai Yuanxin Satellite Technology Co., Ltd. is approximately 1.336 billion yuan, with a focus on launching 94 satellites across seven missions. This indicates a growing emphasis on satellite internet and commercial space development in China [16][17] - Capital expenditures by the three major operators in the first half of 2025 were the lowest in recent years, totaling 112.8 billion yuan, a decrease of 16.5% year-on-year. However, there is an expectation of increased investment in AI and computing infrastructure in the second half of the year, which could significantly boost the domestic computing chain [18][19] Weekly Review and Focus - The communication sector saw a significant increase of 10.47% this week, outperforming major indices. The IDC and optical module sectors continued to lead gains, with increases of 14.59% and 14.41% respectively. The overall performance of the communication sector suggests strong investment opportunities in domestic computing chains and satellite internet [19][20]
