Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] Combine first figure 1 Briefly introduce the structure of the X86 server applicable to the present invention. see figure 1 , the X86 server includes 16 CPUs and 4 PCHs, and each 4 CPUs and 1 PCH constitutes a node ( figure 1 Circled with a box), the CPUs of each node are connected by Quick Path Interconnect (QPI for short), and the CPUs of each node are also connected by QPI. The PCH in each node and its location One CPU connection in the node is, for example, connected by a Direct Media Interface (Direct Media Interface, DMI for short) bus. In addition, each node is configured with a programmable device management, and each programmable device is connected to each other.

[0051] Specifically, CPU1, CPU2, CPU3, CPU4, and PC...

Abstract

A method, device and system for warmly restarting a server, which relate to the technical field of computers. The method comprises: slave programmable devices receive a platform reset signal sent by a master programmable device, the platform reset signal sent by the master programmable device being sent after the master programmable device receives the platform reset signal sent by a master PCH (101); the slave programmable devices trigger slave PCHs to be reset in a case in which the slave PCHs are not powered off (102); and the slave programmable devices keep slave CPUs to be reset in a case in which the slave CPUs are not powered off (103). A master programmable device distributes a platform reset signal sent by a master PCH to slave programmable devices, so that the slave programmable devices trigger corresponding slave PCHs and slave CPUs connected to the slave programmable devices to be reset in a case in which the slave PCHs and the slave CPUs are not powered off, and links that are disconnected before among the slave PCHs and the slave CPUs because the slave PCHs do not work are recovered, and the slave CPUs are reset in a case in which the slave PCHs do not work.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and system for hot restarting a server. Background technique [0002] The server is a high-performance computer in the network environment, which can listen to service requests submitted by other computers (clients) on the network and provide corresponding services. The X86 server is a server using a Complex Instruction Set Computer (CISC for short). The X86 server includes a central processing unit (Central Processing Unit, referred to as CPU), a platform control hub (Platform Controller Hub, referred to as PCH), etc., each of four CPUs and a PCH constitutes a node, and each node is composed of different complex programmable logic devices ( Complex Programmable Logic Device, referred to as CPLD) management. [0003] When the X86 server performs a hot restart, the user sends a reset request to the PCH of each node through hardware or software, and the...
