Abstract

The invention discloses a method for isolating a faulty memory, which comprises the following steps executed by a BMC (Baseboard Management Controller): monitoring the running state of the memory, andrecording the ECC (Error Correction Code) quantity; judging whether the ECC number reaches a first threshold value; in response to the fact that the ECC number reaches a first threshold value, judging whether the ECC number of the memory slot reaches a second threshold value; and in response to the fact that the number of ECC occurring in the memory slot reaches a second threshold, switching offpower supply to the slot. The invention further discloses computer equipment and a readable storage medium. According to the method and the device for isolating the faulty memory and the medium provided by the invention, the specific memory slot position is detected; the abnormal memory slot positions are powered off, so that the whole memory is prevented from being powered off, system interruption or downtime caused by memory failure is avoided, the running stability of the server is improved, and the investment of operation and maintenance personnel and the interruption of services are reduced.

Description

technical field [0001] The present invention relates to the field of memory, more specifically, to a method, device and readable medium for isolating faulty memory. Background technique [0002] The server memory is mainly used to store temporary data for cache use. Whether the server runs stably and smoothly is closely related to the stability and quantity of memory. The memory used on the server has an ECC function, that is, Error Checking and Correcting, and the Chinese name is "Error Checking and Correcting". The ECC in the memory can allow errors to occur during operation and correct the errors so that the system can run normally without being interrupted or down due to memory errors. Due to the constraints of the memory itself, the memory includes multiple memory particles, and various factors such as the memory channels and connectors on the motherboard, in scenarios where a large number of application servers such as data centers will inevitably cause errors in the...
