智能平台管理接口 (IPMI, Intelligent Platform Management Interface) 是一种开放标准的硬件管理接口规格,定义了嵌入式管理子系统进行通信的特定方法。IPMI 信息通过基板管理控制器 (BMC)(位于 IPMI 规格的硬件组件上)进行交流。使用低级硬件智能管理而不使用操作系统进行管理,具有两个主要优点: 首先,此配置允许进行带外服务器管理;其次,操作系统不必负担传输系统状态数据的任务。
IPMI
IPMI(Intelligent Platform Management Interface)是一个硬件管理接口规范,通过ipmi可以远程监控物理健康特征,如温度、电压、风扇工作状态、电源状态、远程启停、远程安装操作系统等。
工作原理
主机有一个专用芯片/控制器,称为基板管理控制器(BMC),它并不依赖CPU、BIOS、操作系统。 只要有BMC和ipmi firmware就可以工作了。
使用
-
开机时设置IPMI Over LAN为On、设置IPMI的ip地址、IPMI用户名和密码。
-
在控制端安装
