Description

TECHNICAL FIELD

[0001] The utility model relates to server power monitoring technical field especially relates to a power monitoring system, server and data center. BACKGROUND

[0002] In the running environment of data center, the power distribution system plays a vital role. The public standard alternating current (AC) and high voltage direct current (HVDC) power transmitted by power plant needs to be converted into low voltage direct current through power supply unit (PSU) to ensure that the server can obtain accurate working voltage. This conversion process is crucial to maintain the stable operation of data center server. However, in the actual operation process, the power supply may encounter various failures. Minor failures may cause the power supply to shut down the output, at which time the redundant power supply will intervene to maintain voltage stability and avoid interruption of data center services. However, serious power supply damage may affect the safety of server lines and even cause server downtime.

[0003] In order to deal with this situation, the server usually reads the black box (Block-Box) information of the power supply through the bidirectional I2C communication standard and PMBus communication protocol of the PSU power supply to obtain the fault or protection reason of the power supply. Once the fault is detected, the server will generate an internal component fault log (log) and communicate with the machine room switchboard through the baseboard management controller (BMC) used for remote monitoring and management in the server, so that the operation and maintenance personnel can timely discover and handle the fault.

[0004] The traditional remote monitoring method usually relies on wired connection.
