Method and system for achieving cache acceleration

Abstract

The invention provides a method and system for achieving cache acceleration. The method and system for achieving cache acceleration are applied to the field of intelligent caches. The method for achieving cache acceleration comprises the following steps that a system interface management module sets cache system parameters according to an instruction input by a user, generates a configuration file, identifies cache system parameter information of the configuration file, and transmits the cache system parameter information to a system management module; after the system management module receives the cache system parameter information, the system management module obtains cache mode information, and transmits the cache mode information to a cache mode analysis module; the cache mode analysis module carries out verification and identification on the cache mode information to obtain a processing result, and sends the processing result to a cache data management module through the system management module; after the cache data management module receives the processing result, the cache data management module obtains a cache strategy and accomplishes transfer according to IO transmitted by an IO dispatching module. According to the method and system for achieving cache acceleration, high-efficiency utilization of an SSD cache space is ensured, the throughput of a memory system is improved, the response time is shortened, and performance of the memory system is integrally improved.

Description

technical field [0001] The invention relates to the field of intelligent cache, in particular to a method and system for realizing cache acceleration. Background technique [0002] With the advent of the era of big data, the information technology industry has gradually changed from how to store data to how to store these data efficiently. Big data refers to data with a huge amount of data, which means both the large quantity and the variety of types. Therefore, in the era of big data, the performance requirements of storage systems are getting higher and higher. How to efficiently store big data poses a huge challenge to traditional storage systems. [0003] Traditional storage systems generally use mechanical hard disks (HDD) to form storage media. Due to their own characteristics, mechanical hard disks have become the performance bottleneck of traditional storage systems. With the emergence and gradual improvement of PCIE SSDs, PCIE SSDs can be used to solve HDD problems...

Problems solved by technology

[0004] However, the SSD cache acceleration system of the storage system faces some problems: SSD has some characteristics. First, SSD has special read and write characteristics, and its read and write performance is asymmetrical. SSD read performance is far greater than write performance, especially in random small data In some cases, write operations have a more serious impact on the performance of SSD; second, the capacity of SSD is far smaller than that of HDD, so SSD space is extremely precious
