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 server dual-partition start-up control method. Background technique [0002] At present, in the field of high-end servers, the number of processors can support up to 8, that is, the so-called 8-way server. The 8-way server can exert more powerful processing and computing capabilities, and has a high degree of scalability. Powerful processing power and memory capacity are the best hardware platforms for databases, front-end applications, and high-performance computing. [0003] The 8 processors can realize the function of redundancy at the same time, so that the system can isolate hardware failures and ensure that the customer's business will never stop. An 8-way server usually uses two computing boards, each of which has 4 processors, and the two computing boards are connected through a physical link through the backplane to achieve the purpose of interconnecting 8 processors...
