Abstract: Embodiments of this application disclose a data storage system, an intelligent network interface card, and a compute node, and belong to the field of data storage. The data storage system includes a compute node and a plurality of storage nodes. The compute node stores metadata, and the metadata may indicate an address at which target data is stored in the plurality of storage nodes. In this way, the compute node may directly read the target data from a corresponding storage node based on the address indicated by the metadata stored in the compute node, does not need to perform cross-node data forwarding by using the plurality of storage nodes, and does not need to perform a plurality of times of metadata searching. This effectively reduces a data reading delay and improves a data reading speed.

Abstract: In a method for storing index metadata associated with stored data, a storage device provides a first metadata storage unit and a second metadata storage unit, wherein a size of the first metadata storage unit is greater than a size of the second metadata storage unit. When a size of target data reaches a specified threshold, the storage device stores index metadata of the target data based on the first metadata storage unit. When the size of the target data is less than the specified threshold, the storage device stores the index metadata of the target data based on the second metadata storage unit.

Abstract: A data processing method in a storage system is provided. The method includes: when the storage system is under a first load, performing an inline deduplication operation; and when the storage system is under a second load, directly storing a received second data block without performing the inline deduplication operation, where the first load is less than the second load.

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 service system and a memory management method and apparatus are provided. The service system includes a plurality of service nodes. A memory of at least one of the plurality of service nodes is divided into a local resource and a global resource. The local resource is used to provide memory storage space for a local service node, the global resource of the at least one service node forms a memory pool, and the memory pool is used to provide memory storage space for the plurality of service nodes. When a specific condition is satisfied, at least a part of space in the local resource is transferred to the memory pool.

Abstract: This application provides a data processing method and a storage device, and belongs to the field of storage technologies. In this application, the storage device performs deduplication and compression based on different granularities, deduplicates data based on a large granularity, and compresses the data based on a small granularity. Therefore, a limitation that a deduplication granularity and a compression granularity need to be the same is removed. A deduplication ratio decrease caused by an excessively large granularity and a compression ratio decrease caused by an excessively small granularity are avoided to some extent, to improve an overall reduction ratio of deduplication and compression.
