Abstract: Embodiments of this application disclose a bandwidth adjustment method and system. The method is applied to a compute express link CXL system. The CXL system includes at least one CXL device and a board management controller BMC, the at least one CXL device includes a first CXL device, and the first CXL device includes at least two logical devices. The BMC obtains an average load state of each logical device in the first CXL device; determines target logical devices in the first CXL device and an adjustment policy based on the average load state; and adjusts bandwidths of the target logical devices according to the adjustment policy. According to the embodiments of this application, bandwidth utilization can be increased.

Abstract: This disclosure discloses a data processing device and method. Specific solutions are as follows: The data processing device includes a processor and an expansion storage apparatus. The expansion storage apparatus is connected to the processor through a CXL interface, and the expansion storage apparatus is configured to store to-be-accessed data of the processor; and a highest priority is configured for a request message for obtaining the to-be-accessed data stored in the expansion storage apparatus. When receiving a request message for processing first data, the processor obtains to-be-accessed data corresponding to the first data from the expansion storage apparatus, to process the first data.

Abstract: A system includes a processor and a memory. The processor locates a first memory chip that is faulty in a memory. After the first memory chip is isolated or replaced, the processor may reset the first memory chip when other memory chips in the memory are maintained to work normally. When a fault occurs in a memory chip in the memory, after the first memory chip that is faulty is isolated or replaced, the processor may independently reset the first memory chip without affecting the other memory chips in the memory. Resetting the first memory chip enables the first memory chip to restore to normal. A memory chip that can be normally used is used as a redundant memory chip or may continue to be used.
