| description | A data access system and method, a device, and a network adapter are provided. In this application, 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; writes the target data into the first storage device based on an indication of the first packet; and 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. In an entire data access process, a processor of the first storage device does not need to participate, and the front-end network adapter of the first storage device performs a data access operation, thereby reducing occupation of computing resources of the processor to some extent, and improving access efficiency of the storage device. |
