Abstract: A metadata processing method includes a network interface card in a storage device that receives an input/output (I/O) request, where the I/O request includes a data read request or a data write request; the network interface card executes a metadata processing task corresponding to the I/O request; and when determining that the metadata processing task fails to be executed, the network interface card requests a CPU in the storage device to execute the metadata processing task.

Abstract: A storage system includes multiple storage nodes. Each storage node includes a first storage device of a first type and a second storage device of a second type, and a performance level of the first storage device is higher than the second storage device. The globe cache includes a first tier comprising the first storage device in each storage node, and a second tier comprising the second storage device in each storage node. The first tier is for storing data with a high access frequency, and the second tier is for storing data with a low access frequency. The management node monitors an access frequency of target data stored in the first tier. When the access frequency of the target data is lower than a threshold, the management node instructs the first storage node to migrate the target data from the first tier to the second tier.

Abstract: A data processing method includes obtaining a plurality of data blocks, determining a first data block and a second data block from the data blocks, where the first data block has a first hash value, and the second data block has a second hash value, where the first hash value is obtained by performing calculation on the first data block based on a hash algorithm and the second hash value is obtained by performing calculation on the second data block based on the hash algorithm, and combining and compressing the first data block and the second data block based on a degree of similarity of the first data block and the second data block.

Abstract: In a method disclosed for writing data, a device receives data, divides the data into one or more data fragments, obtains a first parity fragment based on the one or more data fragments and a second parity fragment of a written data fragment in a stripe distributed across a plurality of nodes, stores the one or more data fragments and the first parity fragment in the stripe.
