摘　　要：目前大多数IPMC设计所选用的BMC芯片的以太网接口有限,只能与服务器共享LAN控制器来实现远程硬件管理和以太网数据传输功能,可靠性不高,且不支持多端口远程管理。针对以上问题,设计了具有以太交换功能的IPMC板卡,该板卡以MSP432E401Y作为主控芯片,利用LAN接口传输IPMI指令,配合二层以太交换芯片KSZ9897R实现服务器多端口远程管理以及数据传输功能。设计中用AES-128算法对IPMI消息进行加密处理,确保数据传输安全可靠。软件测试结果表明,所设计的基于以太交换的IPMC板卡,可以通过LAN接口安全可靠地传输IPMI指令,且满足多端口远程管理和数据传输的需求。At present,most of the BMC chips selected by IPMC design have limited Ethernet interfaces.They can only share LAN controller with the server to achieve remote hardware management and Ethernet data transmission,which has low reliability and does not support multi-port remote management.To solve the above problems,this paper designs an IPMC board with Ethernet switching function.The board uses MSP432E401Y as the main controller,uses the LAN interface to transmit IPMI commands,and cooperates with the L2 Ethernet switch chip KSZ9897R to realize the server multi-port remote management and data transmission functions.AES-128 algorithm is used to encrypt IPMI messages to ensure safe and reliable data transmission.According to the software test results,the IPMC board designed in this paper can transmit IPMI instruction safely and reliably through LAN interface,and meet the requirements of multi-port remote management and data transmission.
