Mass storage end-to-end data protection system based on power down protection

Abstract

The invention in particular relates to a mass storage end-to-end data protection system based on power down protection. The mass storage end-to-end data protection system based on power down protection comprises a power module, wherein the power module comprises a system power supply, a boosted circuit, a primary DC / DC power module and a secondary DC / DC power module connected in sequence; the power module boosts the system power supply from +12V to +28V; and the primary DC / DC power module outputs the voltage of +28V to be +3.3V. The mass storage end-to-end data protection system further comprises a master control FPGA (Field Programmable Gate Array) and a FLASH array, wherein a rapid power failure detection circuit is arranged between the system power supply and the master control FPGA; the rapid power failure detection circuit, the master control FPGA and the FLASH array are connected in sequence; the secondary DC / DC power module is respectively connected with the master control FPGAand the FLASH array; and a tantalum capacitor array is arranged between the boosted circuit and the primary DC / DC power module. With the adoption of the rapid power failure detection circuit, the master control FPGA has more time to process the power failure interrupt program, and the safety of the end-to-end data protection is improved.

Description

technical field [0001] The invention relates to the technical field of large data storage, in particular to an end-to-end data protection system for large-capacity storage based on power-off protection. Background technique [0002] With the development of science and technology, society has entered the era of big data analysis, and there is a higher demand for large-capacity storage. The capacity requirements are increasing, the speed requirements are faster, and the interface requirements are diversified. At the same time, data security and confidentiality Sex and importance are gaining more and more attention. [0003] In this era of "gold is priceless, data is priceless", how to effectively protect data from loss is very important, especially when the system suddenly loses power or shuts down abnormally, it is necessary to quickly save the mapping table and cache data of the storage disk. The key technical difficulties of storage lie in the fact that large capacity, div...
