Abstract
A solid-state disk access control method and apparatus, a computer device, and a storage medium are provided. The method includes: detecting controller nodes connected to a Peripheral Component Interconnect Express (PCIe) switch and Non-Volatile Memory Express (NVMe) solid-state disks connected to the PCIe switch; setting a first mapping connection relationship to be formed between each NVMe solid-state disk and one of the controller nodes, and setting second mapping connection relationships to be formed between each NVMe solid-state disk and the remaining controller nodes; and under a condition that any NVMe solid-state disk is accessed, in response to a determination that the first mapping connection relationship is abnormal, selecting one of the remaining controller nodes as a standby controller of the accessed NVMe solid-state disk, and modifying the second mapping connection relationship between the standby controller and the accessed NVMe solid-state disk to the first mapping connection relationship.
