In one example method, a client device sends a first packet to a first storage device, to request that target data can be written into the first storage device, where the first packet includes a logical address into which the target data needs to be written. A front-end network adapter of the first storage device has a capability of parsing the first packet, and can process the first packet. The front-end network adapter of the first storage device writes the target data into the first storage device based on an indication of the first packet. The front-end network adapter of the first storage device generates metadata, and records a correspondence between the logical address of the target data and the metadata, where the metadata can indicate a physical address at which the target data is stored in the first storage device.

A method for implementing storage service continuity in a storage system includes a front-end interface detecting a status of a first storage controller. The storage system includes the front-end interface card and a plurality of storage controllers. The front-end interface card communicates with the storage controllers, and the front-end interface card communicates with a host. When the first storage controller is in an abnormal state, the front-end interface card selects a second storage controller from the storage controllers for the host to process an access request of the host.
