Problems solved by technology

[0004] Common SSD performance testing software such as CrystalDiskMark, PCMArk, etc. These software only analyze the overall performance and test the performance of the entire system, which means that the performance analysis of all the above-mentioned modules as a whole cannot obtain the performance of each module. The specific performance of the NVMe module cannot be obtained
Therefore, when the system performance is low and needs to be optimized, the performance of the NVMe module of the SSD system cannot be accurately known according to this test method

Abstract

The invention discloses a method and system for effectively analyzing the performance of an SSD front-end NVMe module. The method includes the following steps: using a DRAM module to simulate a Flash module at the back end of an SSD; receiving and executing a command from a host; Perform data transmission between; obtain SSD performance data as NVME module performance data. This solution uses the DRAM module to simulate the Flash module at the back end of the SSD, and fully realizes the function of the NVMe module. Through the SSD performance test, the ultimate performance of the NVMe module hardware IP at the front end of the SSD can be obtained, and the hardware IP of the NVMe module can be accurately understood. Performance, and maintain or upgrade the SSD according to the performance of the NVMe module hardware IP, so as to improve the overall performance of the SSD and improve the product experience.

Description

technical field [0001] The present invention relates to the field of SSD analysis, in particular to a method and system for effectively analyzing the performance of an SSD front-end NVMe module. Background technique [0002] The full English name of SSD is Solid State Disk, and the Chinese name is solid state hard disk, referred to as solid disk. Solid state hard disk is a hard disk made of solid state electronic storage chip array, which consists of a control unit and a storage unit (FLASH chip, DRAM chip). [0003] The entire SSD system is composed of multiple modules, and common system performance analysis is usually performed on the performance of the entire system. Such as figure 1 As shown, the complete system architecture of the existing SSD mainly includes Controller, DRAM and FLASH, and the controller mainly includes PCIe, NVMe, DPM, FTL, NFC, DDR, and Platform modules. The existing NAND FLASH Program is usually divided into two processes. First write HOST data in...
