Abstract

The invention provides a device of monitoring server CPLD (Complex Programmable Logic Device) status. The device includes a BMC (Baseboard Management Controller), a CPLD and a storage module. The BMCis connected with the CPLD, used for reading data of detecting internal registers and sensors of the CPLD, and judging whether the data of the registers and the sensors are in working setting ranges,and also used for recording abnormal working status of the CPLD. The storage module is respectively connected with the BMC and the CPLD, and used for temporarily storing monitoring information of theCPLD status. According to the device of monitoring the server CPLD status, a method of monitoring the server CPLD status through the BMC is adopted, the BMC establishes data interaction with the CPLDthrough JTAG interfaces and an I2C bus, collection of important monitoring signals cannot be missed, and highly efficient and also comprehensive monitoring on server CPLD status information is realized.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a device and a method for monitoring the state of a server CPLD. Background technique [0002] With the rapid development of economy and society, my country is about to usher in the Internet + era. The advent of the Internet + era is accompanied by the rapid rise of the server industry. Massive data is impacting various industries with an unprecedented growth trend. Servers are widely used due to their excellent performance. In cloud computing, big data processing, network platform and other fields, it is favored by the market. [0003] During the debugging and use of the server, sometimes problems such as power failure, shutdown, and downtime may occur due to the failure of the server CPLD. In order to troubleshoot these problems, debuggers need to know the status of the parts where the fault occurs. In the prior art, debuggers can use oscilloscopes or voltmeters to...
