Description
技术领域 technical field
本发明涉及计算机散热技术领域，具体地说是一种实用性强、基于CPU Margin温度的整机柜风扇调速方法。 The invention relates to the technical field of computer heat dissipation, in particular to a highly practical method for adjusting the speed of a fan in a complete cabinet based on the CPU Margin temperature.
背景技术 Background technique
随着计算机技术的高速发展，整机柜服务器在实际应用中尤其在大型数据中心、云计算基地等场合应用越来越广泛，在整机柜中集成几十个服务器节点，实现高密度部署。在整机柜上，每个节点的CPU没有独立的风扇来散热，而是通过机柜后部的风扇窗整体给所有节点散热。一般整机柜服务器会通过节点BMC采集节点的CPU温度，进风口温度等数据，在不同的进风口温度区间，BMC根据CPU温度变化选择事先通过测试得到的风扇duty表中的duty，RMC通过节点中板从BMC中获取到此duty，从半柜所有节点duty中选择一个最大的duty值控制半柜风扇。 With the rapid development of computer technology, the whole cabinet server is more and more widely used in practical applications, especially in large data centers, cloud computing bases and other occasions. Dozens of server nodes are integrated in the whole cabinet to achieve high-density deployment. In the entire cabinet, the CPU of each node does not have an independent fan to dissipate heat. Instead, the fan window at the rear of the cabinet dissipates heat for all nodes as a whole. Generally, the whole cabinet server will collect data such as the CPU temperature and air inlet temperature of the node through the node BMC. In different air inlet temperature ranges, the BMC selects the duty in the fan duty table obtained through the test in advance according to the CPU temperature change, and the RMC passes the node. The middle board obtains the duty from the BMC, and selects a maximum duty value from the duty of all nodes in the half cabinet to control the fan of the half cabinet.
但此种方式一个明显缺点就是：因CPU型号较多，如果按照通常做法，通过实际测试来得到每种型号的CPU温度与满足此温度下CPU散热的风扇duty的对应关系表，无疑测试工作量会非常大。如果后续CPU型号更换或CPU升级，即每出现一种新型号的CPU，就要根据CPU特性实际测试得到散热duty表，BMC再根据调速策略表编写对应的调速策略软件，不仅加大BMC软件开发的工作量，而且以后BMC版本升级维护也非常不方便。因此，如何能实现一种调速策略覆盖所有型号CPU的散热，成为设计和开发人员亟需解决的问题。基于此，现提供一种基于CPU Margin温度的整机柜风扇调速方法。 However, an obvious disadvantage of this method is that since there are many CPU models, if you follow the usual practice and obtain the correspondence table between the CPU temperature of each model and the fan duty that satisfies the CPU heat dissipation at this temperature, the workload of the test will undoubtedly be obtained. will be very large. If the subsequent CPU model is changed or the CPU is upgraded, that is, every time a new type of CPU appears, the heat dissipation duty table must be obtained according to the actual test of the CPU characteristics. The workload of software development, and it is very inconvenient to upgrade and maintain the BMC version in the future. Therefore, how to implement a speed regulation strategy to cover the heat dissipation of all types of CPUs has become an urgent problem to be solved by designers and developers. Based on this, a method for adjusting the fan speed of the whole cabinet based on the CPU Margin temperature is now provided.
