Embodiment Construction

[0027] The core of the present invention is to provide a dual-partition power-on control method of a server to realize the staggering of the time intervals during which the two partition QPI buses are trained, so as to ensure the normal power-on of the two partitions.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Please refer to figure 1 , figure 1 This is a flow chart of a method f...

Abstract

The invention discloses a double-zone power-on control method for a server. The method comprises the following steps that: power buttons of two zones of the server are triggered in a remarkably short period of time respectively, wherein the power button of a first zone generates a first undershoot signal and the power button of the second zone generates a second undershoot signal; an IO module judges the pressing sequence of the power buttons of two zones according to the first undershoot signal and the second undershoot signal to generate a first identification signal and a second identification signal; the first zone judges the power-on sequence of the first zone according to the first identification signal and the second zone judges the power-on sequence of the second zone according to the second identification signal; the zone in first power-on sequence is electrified to be powered on, a time identification signal is sent to the zone in a second power-on sequence and the zone is electrified to be powered on after a preset period of time. According to the method, training time intervals of QPI (Quick Path Interconnect) buses of two zones are staggered, so that two zones can be powered on normally.

Description

Technical field [0001] The invention relates to the technical field of servers, in particular to a method for controlling the power on of a server with dual partitions. Background technique [0002] Currently, in the field of high-end servers, the number of processors can support up to 8, the so-called 8-way servers. The 8-way server can play a more powerful processing capacity, and has a high degree of scalability. Powerful processing power and memory capacity is the best hardware platform for databases, front-end applications, and high-performance computing. [0003] 8 processors can simultaneously achieve redundancy, enabling the system to isolate hardware failures and ensure that customer business never stops. An 8-way server usually uses two computing boards, each with 4 processors, and the two computing boards are connected by a physical link through a backplane to achieve the purpose of interconnecting 8 processors. That is, each computing board is an independent 4-way se...
