Embodiment

[0017] The method for controlling the power-on of a multi-node server system described in this embodiment takes the four-star server system as an example; by setting a logic "AND" processing unit on the system board of the four-star server, the Perform logic "AND" operation on the power-on EN signal of the system to output the system power-on EN signal SYS_EN, use the SYS_EN signal to enable and control the P12V output of the PSU, and then control the power-on of the server node. The logic "AND" processing unit includes a 4-input AND gate chip.

[0018] The method for controlling the start-up and power-on of a multi-node server system described in this embodiment, its specific implementation includes the following steps: 1) in the four-star server system, independently define the start-up EN signals of the 4 server nodes, 2) define the 4 The boot EN signal of each server node: NODE_EN0\NODE_EN1\NODE_EN2\NODE_EN3 performs logic "AND" operation on the system board, and outputs t...

Abstract

The invention discloses a method of controlling power-on of a multi-node server system and relates to the field of universal server power supply; the method comprises: setting a logic 'AND' processing unit on a system medium plate of the multi-node server system, subjecting power-on EN signals of a plurality of server nodes to logic 'AND' operation, outputting a system power-on EN signal SYS_EN, using the signal SYS_EN to enable the control of P12V output of a PSU (power supply unit) so as to control power-on of the server nodes. Power-on or power-off action is done for any one or more server nodes in a four-component server system according to the method, working state of other server nodes may not be affected, and high availability and reliability of the system are guaranteed.

Description

technical field [0001] The invention relates to the field of general server power supply, in particular to a method for controlling the power-on of a multi-node server system. Background technique [0002] With the continuous increase of Internet business volume, the storage capacity of data center network data has become a bottleneck restricting business development. Some network operators, in order to meet business needs, have to invest huge sums of money to rebuild new and larger data center rooms. In order to save costs, some other network operators can only take the method of making full use of the existing computer room space, and increase the data processing capacity of the server system occupying limited space as much as possible, so as to temporarily meet the development needs of their own business. In order to meet the needs of such customers as much as possible, different forms of high-density server systems have emerged as the times require. [0003] The usual ...
