《IPMI 1.5协议书》是一项智能平台管理接口规范，最初发布于1998年，目前已经到达1.5版本。该规范是由Intel、惠普、NEC和Dell等公司联合开发的，旨在提供一种标准化的管理接口，用于监控和控制计算机系统的硬件和软件。该规范于2002年2月20日的修订版1.1正式发布。这个规范的目标是提供一种标准的管理接口，使得管理者可以远程监控和管理计算机系统，而不需要物理接触。它定义了一套协议和命令集，用于与计算机系统的管理控制器通信。通过使用这些命令，管理者可以执行诸如电源控制、温度监测、事件记录等操作，以保证计算机系统的正常运行。该规范的1.5版本在1.0版本的基础上进行了改进和扩展。根据修订历史记录，1.0版本在1998年9月16日发布，是首个发布的IPMI规范，包含了最初的功能和命令集。1.1版本作为1.0版本的勘误修订版，于1999年8月26日发布，纠正了一些错误，并添加了更多的澄清。最终，1.5版本于2001年2月21日发布，引入了一些新的功能和命令，并加入了一些改进和优化。《IPMI 1.5协议书》的内容涵盖了硬件和软件管理方面的要求和功能。它定义了通信接口的物理和逻辑特性，包括接口类型、信号电压和速率等。此外，该规范还详细描述了通信协议的组成和通信过程，包括命令的格式、数据传输的方式和错误处理机制等。该规范还涵盖了许多管理功能，以提供全面的管理能力。其中包括电源管理，管理者可以通过IPMI接口控制计算机的开关机，并获取电源状态信息。温度监测功能使管理者能够实时监测计算机系统的温度，以避免过热导致硬件故障。事件记录功能可以记录和报告系统发生的事件和错误信息，帮助管理者进行故障排查和维护。除了基本功能外，该规范还提供了一些高级功能，如远程控制和虚拟媒体功能。远程控制功能允许管理者通过IPMI接口远程访问计算机系统，并对其进行操作和配置。虚拟媒体功能允许管理者将远程的光驱或USB设备映射到计算机系统，以实现远程安装操作系统或加载软件。《IPMI 1.5协议书》不仅适用于服务器和计算机系统，还适用于嵌入式系统和网络设备等。通过实现这个规范，厂商可以提供一致的管理接口，简化系统部署和管理，并提高系统的可靠性和可维护性。总之，《IPMI 1.5协议书》是一份重要的管理接口规范，为计算机系统的远程监控和管理提供了一种标准化的解决方案。它定义了一套通信协议和命令集，满足了管理者对硬件和软件管理的多种需求。同时，通过实现这个规范，厂商可以提供一致的管理接口，简化了系统部署和管理的复杂性。
