Embodiment Construction

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] figure 2 It is a flowchart of a method for isolating memory faults on a server provided by an embodiment of the present invention, such as figure 2 shown, including:

[0040] Step S201: when the server is powered on or restarted, the BIOS obtains the memory failure information stored in the BMC about the failure of the server memory;

[0041] Step S202: The BIOS analyzes the memory fault information according to the interface configuration of the server, and determines whether the faulty memory needs to be isolated;

[0042] Step S203: If it is determined that the failed memory needs to be isolated, the BIOS determines the isolation level of th...

Abstract

The invention discloses a method and a device for isolating memory failure on a server, relating to the technical field of a server product. The method comprises: when a server is powered on or restarted, a BIOS obtains memory failure information about the memory failure of the server stored in a BMC; ; the BIOS analyzes the memory fault information according to the interface configuration of theserver, and judges whether the failed memory needs to be isolated or not; if it is judged that the faulty memory needs to be isolated, the BIOS determines the isolation level of the faulty memory, andisolates the faulty memory according to the determined isolation level.

Description

technical field [0001] The invention relates to the technical field of server products, in particular to a method and device for isolating memory faults on a server. Background technique [0002] On current mainstream servers, such as figure 1 As shown, before the memory is installed in the server, the product line will conduct some necessary production tests on the memory to screen out the memory with risks or problems; the server will use different software algorithms or hardware methods during the power-on and startup process Quickly detect the memory and isolate the found faulty memory; during the operation stage of the business and operating system, record and report the correctable memory error through ECC (Error Correcting Code, error checking and correction) (some servers can be changed by changing The application uses memory space mapping to realize online "isolation" recovery), records and reports multi-bit uncorrectable errors, and replaces or removes the faulty ...
