Sequence top-and-down electricity system and method for knife sheet type server system initial state

Abstract

A system and method for sequentially powering on and off the initial state of a blade server system, comprising: a fan, a blade, a switch, an IOE expansion module, a management module, and a power system, and the power system is divided into: a power management domain for supplying power to an initial mode management subsystem and the power supply task domain for each module to be powered in the normal working mode; the system can safely and stably power on and power off under the initial state and the running state (that is, support the module to carry out hot-swapping operation); adopt the method of the present invention to solve When powering on and off, because each blade has a peak current problem at the moment of power on, and there is a problem of excessive current at the moment, and the impact on the power system and the external power grid during the power on and off process is eliminated to solve the current problem. There are a series of security issues.

Description

technical field [0001] The invention relates to a power-on / off method of a cluster system, in particular to a power-on / off strategy of a computing blade server system. Background technique [0002] Today's blade server system is a high-density system that can usually accommodate several to ten or twenty blade servers. The power supply is the power source of the blade system, and its safety and reliability are directly related to the performance of the entire system. Since the system is a huge power-consuming system, it is particularly important to design the power-on and power-off scheme of the blade system. During the operation of the blade system, it is necessary to monitor the health status and operation status of each module at any time, so that the administrator can keep abreast of the operation of the system. status, discover abnormal situations in the process of operation in time, and deal with them accordingly to ensure the normal operation of the blade system. When...

AI Technical Summary

Problems solved by technology

When multiple blades in the system need to be powered on and off, because each blade has a peak current problem at the moment of power-on, if multiple blades are powered on and off at the same time, there will also be an instantaneous excessive current problem

The entire blade system is a huge power-consuming system. If it is powered on and off at the same time, it will also have an impact on the power grid of the power supply system.
