Abstract

The invention provides a storage system of a database all-in-one machine and a data request processing method and device. A PMEM is configured for a storage node of the database, the PMEM and the DRAMmeet the consistency design requirement, and the storage node is further configured with a flash disk. According to the invention, a PMEM is arranged at a storage node; the data on the PMEM can be directly read by using the memory access mode for the data with high frequency access instead of being loaded from the traditional flash disk through a file system and a storage stack, so that the delayof accessing the data by the storage node of the all-in-one machine can be greatly reduced, the execution efficiency of the storage node is improved, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of database storage, in particular to a storage system of a database integrated machine and a data request processing method and device. Background technique [0002] Generally, high-performance database all-in-one machines are mainly for enterprise-level key core businesses, and are used for better performance improvement of customer systems. Therefore, the basic requirements for designing a database all-in-one machine are high reliability, high performance and high scalability. Inspur's K-DB database all-in-one machine is an integrated solution developed and designed based on the open X86 fusion platform and Inspur database software K-DB, which has the advantages of high performance, high expansion, and high reliability. [0003] The overall composition of the K-DB database all-in-one machine is divided into three parts: computing nodes, storage nodes and high-speed networks. Among them, computing nodes,...
