Title:
STORAGE SYSTEM, NETWORK INTERFACE CARD, PROCESSOR, AND DATA ACCESS METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/257685
Kind Code:
A1
Abstract:
A storage system, a network interface card, a processor, and a data access method, apparatus, and system. In the present application, the storage system comprises an I/O stack and a processing unit, and the I/O stack comprises a plurality of storage layers. The processing unit can receive a data read request, the data read request being used for reading target data stored in the storage system; the processing unit queries a global index on the basis of the data read request, wherein the global index can indicate the storage layer in the I/O stack where the target data is located; and the processing unit can read the target data from the storage layer after determining, according to the global index, the storage layer where the target data is located. When processing the data read request, the processing unit in the storage system directly determines, by querying the global index, the storage layer where the target data is located, and there is no need to sequentially traverse a storage medium in the storage system, such that delay caused due to traversing the storage medium is omitted, the processing process of the data read request is more efficient, and the data read efficiency can be effectively improved.
