Abstract

The invention discloses an achievement method of a flash memory storage array. The achievement method comprises an IO acceleration module, a service calculating module, a flash memory group module anda management module, wherein data packets and data application packets from the front end undergoes parsing and acceleration and / or service quality control through the IO acceleration module and perform data interaction with the service calculating module, the service calculating module is used for executing calculation and flash memory group resource management of service software programs and / or data services and directly performs data interaction with the flash memory group module, and the flash memory group module provides reading, writing and erasure functions and provides data service calculation without additional memories. The management module executes control and monitoring functions of the flash memory storage array. By adopting the method, IO path operation is decreased, IO delay is shortened, accordingly the characteristics of flash memories can be more effectively utilized, and the properties of the flash memories can be played. In addition, the flash memory group modulecan be flexibly increased / decreased and meanwhile has transverse extension capability.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method for realizing a high-performance flash memory storage array with horizontal expansion capability. Background technique [0002] With the development of semiconductor technology, the storage density of flash memory is getting higher and higher. Compared with mechanical disks, flash memory (NandFlash) has faster random access speed, especially random read access speed, and lower power consumption. Compared with DRAM (Dynamic Random Access Memory, dynamic random access memory), flash memory can keep data for a long time after the power is turned off, and has higher storage density. Widely used in high IOPS (Input / OutputOperationsPerSecond), high bandwidth (Bandwidth), and low latency (Latency). [0003] However, existing flash memory storage arrays are based on off-the-shelf general-purpose hardware and are implemented software-centrically, such as figure 1 As shown,...
