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.

Providing a data processing manner, wherein: a SSD compresses a data; the SSD storing the compressed data; the SSD sends a feedback information to a controller, wherein the feedback information indicates a remaining capacity of the SSD after the compressed data is stored.

Smart storage management based on dynamic logic capacity for the storage

A multi-disk fault-tolerant system, a method for generating a check block, and a method for recovering a data block are provided. The multi-disk fault-tolerant system includes a disk array and a calculation module connected through a system bus, the disk array is formed by p disks, and a fault-tolerant disk amount of the disk array is q; data in the disk array is arranged according to a form of a matrix M of (m+q)&#xd7;p, where m is a prime number smaller than or equal to p&#x2212;q; in the matrix M, a 0row is virtual data blocks being virtual and having values being 0, a 1row to an (m&#x2212;1)row are data blocks, an mrow to an (m+q&#x2212;1)row are check blocks. Therefore, during a procedure of generating the check block and recovering the data block in the multi-disk fault-tolerant system, calculation complexity is lowered.
