人工智能服务器的底板管理控制器系统设计

Design of Baseboard Management Controller System for Artificial Intelligence Server

针对人工智能计算单元或加速卡需要稳定可靠的工作电源以及实时高效的温度控制等需求,设计人工智能服务器的底板管理控制器系统,实现人工智能服务器的电源模块冗余管理、多路电源输出监测、机箱内部温度控制,并提供远程接口和设备管理能力。该系统采用ORing冗余电源设计,对每路输出电源进行电压、电流状态监测;结合人工智能服务器的内部温度信息,依据电压、电流历史趋势对其散热风扇实施转速控制,不仅实现了电源冷、热冗余备份和切换管理,还有效提高了服务器的散热水平。应用该系统的人工智能服务器“香雪-3B”(XIANGXUE-3B)运行稳定可靠,并在MLPerf V2.0测试中取得了较好的成绩。

To meet the requirements of stable and reliable working power supply and real-time and efficient temperature control for the artificial intelligence computing unit or accelerator card,the floor management controller system of the artificial intelligence server is designed to realize the redundant management of the power module of the artificial intelligence server,multi-channel power output monitoring,and temperature control inside the chassis,and provide remote interface and equipment management capabilities.ORing redundant power supply design is adopted to monitor the voltage and current status of each output power supply;Combined with the internal temperature information of the AI server,the speed of the cooling fan is controlled according to the historical trend of voltage and current,which not only realizes the cold and hot redundancy backup and switch management of the power supply,but also effectively improves the cooling level of the server.The artificial intelligence server"XIANGXUE-3B"using this system runs stably and reliably,and has achieved good results in MLPerf V2.0 test.
