Method and device for quickly starting multiple groups of computer systems

Abstract

The invention relates to the technical field of computer application, and discloses a method and device for quickly starting multiple groups of computer systems. The system comprises management controllers used for generating characteristic parameters required for starting computer node systems and configuration interfaces used for storing the characteristic parameters, the management controllers are located in all computers, the management controllers are provided with configuration interfaces. According to the method and device for quickly starting multiple groups of computer systems, each computer node is provided with a feature parameter configuration interface used for starting the storage system, a computer can pre-read feature parameters used for starting the storage system before starting, and if the read feature parameters are not available, a new characteristic parameter can be generated for the computer node through the management controller, and then the new characteristic parameter is written into the configuration interface of the computer node, so that the computer node quickly has a unique authentication identity, and the starting process of the system is accelerated.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a quick start method and device for multiple groups of computer systems. Background technique [0002] With the development of information technology, computers have been widely accepted and used by users. In the boot process of traditional computers, when the computer is powered on, the computer will first load the basic input and output system, and the basic input and output system will perform many actions. For example, power-on self-test, hardware detection, driver installation and operating system loading, etc., due to the increasing size of the operating system of the computer, and more and more application programs that are automatically started when the computer is turned on, the startup time of the operating system is getting shorter and shorter. long.

Problems solved by technology

[0003] In a multi-group computer system composed of multiple nodes, there are different application requirements for powering on / resetting multiple nodes. Quickly starting these computer nodes is one of the main functions of the parallel computer system management software. An important part of group computer system management automation. In a large-scale parallel computer system, due to the large number of computer nodes, these tasks are very time-consuming; another method is to use the switch port number connected to the computer node as the configuration basis , the advantage is that computer nodes can be replaced at will without considering the impact of MAC address changes, but this method requires that the switch can be managed and the mapping relationship between nodes and switch ports cannot be changed at will. It often happens that it is unstable and has to switch to other ports, so this method still lacks flexibility. When more computer nodes are started at the same time, the performance and bandwidth of the startup server may not match the requirements, resulting in slow system startup.
