The embodiment of the present invention discloses a dynamic power management system, which includes two or more PSUs. The system also includes: a mid-backboard, a CMC board, and a node Node. There are two CMC boards, and the node Node has One or more, the PSU is arranged on the mid-back board, and the PSUs are connected to the outside in parallel, and each CMC board is connected to all PSUs on the mid-back board through a CMC connector, and each node Node is connected to a node through a node The connector is connected to the mid-backplane; the CMC board is a redundant design, and the CMC board is used for in-position detection and power consumption detection of the PSU, and the CMC board is used for controlling the Power capping trigger mechanism. Nodes are used to limit the power consumption of the nodes, and the mid-backplane is used to supply power to the system. The present invention uses BMC and CPLD to jointly realize logic control, so as to solve the problems in the prior art that it is impossible to manage redundancy of power supplies of different specifications and to realize quick response to power supply alarms, so that the control mode is more flexible.
Description
Technical field [0001] The present invention relates to the field of power management technology, and more particularly to a dynamic power management system. Background technique [0002] With the development of technology, the application of servers is getting wider. High-density servers have the advantages of small occupied space and system more concentrated. High-density servers shared power and fans in the same chassis, integrating more processors and I / O expansion capabilities in smaller physical space, so higher requirements for power supply, must be used Multiple power supply is powered. [0003] In order to improve the reliability of the server, the power supply is usually designed in high-density servers. For example, when the 4 power supply is supplied, 3 + 1 power redundancy can be allowed to allow 1 power failure, and the remaining three power supplies can still meet the power supply requirements of the entire system. Due to the flexibility of the high-density serve...
