Abstract
A method for improving reliability of a storage system and a related apparatus, where the storage system includes a first control device and a second control device. The method includes receiving, by a target controller, a write request, where the write request includes to-be-written data, and the target controller belongs to the first control device; writing, by the target controller, the to-be-written data into a memory of the target controller; and writing, by the target controller, the to-be-written data into a memory of a mirror controller of the target controller, where at least one mirror controller belongs to the second control device.
