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 storage system includes a management node and multiple storage nodes. Each storage node includes a first storage device of a first type (e.g., DRAM) and a second storage device of a second type (e.g., SCM), and a performance level of the first storage device is higher than the second storage device. The management node creates a globe cache including 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 of the globe cache.

Abstract: A data storage system includes a host, an adapter card, and a storage node. The host establishes a communication connection to the adapter card through a bus, and the storage node establishes a communication connection to the adapter card through a network. The storage node is configured to store data that the host requests to write into a first memory space. The first memory space is a storage space that is provided by the adapter card for the host and that supports memory semantic access. The adapter card writes the data into a second memory space of the storage node, where the adapter card includes a first correspondence between a physical address of the second memory space and an address of the first memory space.

Abstract: This application discloses a storage system, a data processing method, an apparatus, a node, and a storage medium, and pertains to the field of data storage technologies. In the method, a client determines an address that is in a storage unit and that is used to store to-be-written data, and sends the to-be-written data to a first storage device that is in a storage node and that is corresponding to the storage unit, so that the first storage device stores the to-be-written data while a CPU of the storage node does not need to determine a hard disk LBA corresponding to virtual address space, and a hard disk does not need to determine a corresponding physical address based on the hard disk LBA.
