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.

Embodiment Construction

[0090] Below in conjunction with accompanying drawing, the present invention will be further described.

[0091] see Figure 1 to Figure 6 :

[0092] The power system is responsible for providing power to each module and chassis in the entire blade system, performing power-on sequence control and power distribution; power-off sequence control and power recovery; power redundancy control, power module failure analysis, and alarm. The power system adopts two voltage working modes to divide the whole power system into two work domains: Power Management Domain (Power Management Domain: PMD) and Power Task Domain (PowerTask Domain: PTD).

[0093] A sequential power-on and power-on system of a blade server system of the present invention includes: a fan (FAN), a blade (Blade), a switch (SW), and an IOE expansion module, and its special feature is that it also includes:

[0094] Management module (MM), adopts "centralization" to connect and control power system, IOE expansion modul...

Abstract

A sequence up and down electrical system of the blade service equipment and its method, the system is the thermal mobile status. It includes the fan, blade, exchanger, IOE extended modular, managerial modular and power system which can be divided into initial state power administrative domain which administrate the subsystem and normal working state power mission domain. The system can be steady and safety loading and unloading electricity. Through this invention we can overcome there is a peak current on the blade when it is loaded electricity and the transient current is over stronger, this invention also erases the damage to power system and external electrical net during the loading and unloading process.

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...
