服务器：OCP 的 10 大关键要点

Summary of Key Takeaways from APAC's OCP Summit Industry Overview - The report focuses on the AI server development industry, particularly the challenges and innovations discussed at the APAC's Open Compute Project (OCP) Summit held in Taipei on August 5-6, 2025. Core Points and Arguments 1. AI Datacenter Clusters and Power Innovations: Current large-scale datacenters consume between 50-100MW and are not fully compliant with AI server hosting standards. Companies like Meta are planning to build Titan AI clusters, with the first 1GW+ AI datacenter (Prometheus) expected to be operational by 2026. Another datacenter, Hyperion, will have a capacity of up to 5GW. Key beneficiaries include Delta, Vertiv, and power plant vendors [1][12][31]. 2. Capex Increase for US CSPs: The top four US Cloud Service Providers (CSPs) are expected to increase their capital expenditures (Capex) by 55% and 25% year-over-year in 2025 and 2026, respectively, indicating a robust multi-year investment in AI infrastructure [1][12]. 3. Modular Design Trends: The DC-MHS (Datacenter Modular Hardware System) is gaining traction as a modularized computing platform that enhances scalability and cost efficiency. Intel is a key player in this trend, which is expected to see high adoption rates starting with its next-generation server platform [9][12]. 4. Customized Liquid Cooling Solutions: There is a rising demand for customized liquid cooling solutions among the top four US CSPs. Amazon is shifting to its proprietary thermal solution, IRHX, while Google is developing a customized L2L CDU design. Delta is identified as a key ODM for these solutions [12][31]. 5. HVDC Power Technologies: The report discusses bifurcated HVDC (High Voltage Direct Current) power technologies, with a focus on the ±400V architecture being more favorable due to its compatibility with existing datacenter practices. This shift could benefit suppliers of SiC or GaN components [18][21]. 6. Increased Content in Power Rack Designs: CSPs are expected to introduce side power rack designs to accommodate higher power density. This will lead to significant content increases for system vendors like Delta, as the complexity of power delivery systems rises [21][23]. 7. Vertical Power Delivery Adoption: Vertical power delivery is anticipated to become more common in next-generation AI accelerators, driven by the need for power efficiency. This trend is expected to benefit power vendors like Delta and Infineon [29][31]. 8. Networking Equipment Upgrades: The demand for high-end networking equipment is increasing due to the growth of AI clusters. Ethernet technologies are being explored as alternatives to Infiniband for scale-up networking solutions, which could benefit Ethernet switch vendors [31][32]. Other Important Insights - The introduction of OpenBMC and Caliptra is expected to enhance security in server designs without necessarily lowering entry barriers for BMC chip vendors [7][12]. - The report highlights the importance of customized solutions in the evolving landscape of AI server infrastructure, indicating a shift towards more tailored approaches in hardware design and cooling solutions [12][31]. This summary encapsulates the key insights and trends discussed at the OCP Summit, emphasizing the ongoing innovations and investment opportunities within the AI server development industry.
