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 QuickPath Interconnect (QuickPathInterconnect, QPI for short), and the CPUs of each node are also connected by QPI. One way of CPU connection, such as direct media interface (DirectMediaInterface, DMI for short) bus connection. 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 PCH1 form a node, and are managed by ...

Abstract

The invention discloses a method, a device and a system for warmly restarting a server, belonging to the technical field of a computer; the method comprises the following steps: slave programmable devices receive a platform reset signal sent by a master programmable device, wherein the platform reset signal sent by the master programmable device is sent after the master programmable device receives the platform reset signal sent by a master PCH (Platform Controller Hub); the slave programmable devices trigger slave PCHs to reset under no power outage condition; and the slave programmable devices trigger slave CPUs (Central Processing Unit) to reset under the no power outage condition. According to the method, the device and the system disclosed by the invention, through distributing the platform reset signal sent by the master PCH to each of the slave programmable devices via the master programmable device, each of the slave programmable devices triggers the connected slave PCHs and the slave CPUs to reset under the no power outage condition; and links which are disconnected before among the slave PCHs and the slave CPUs due to a fact that the slave PCHs do not work are recovered, so the reset of the slave CPUs under the condition that the slave PCHs do not work is realized.

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 (PlatformControllerHub, referred to as PCH), etc., each of four CPUs and a PCH constitutes a node, and each node is composed of a different complex programmable logic device (Complex ProgrammableLogicDevice, 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 PCH...
