Phase change memory-based heterogeneous storage device and method

Abstract

The invention provides a phase change memory-based heterogeneous storage device and method. The heterogeneous storage device comprises a central processing unit, the phase change memory, an FPGA, a DRAM and a backup power supply; the central processing unit is connected with the DRAM and the FPGA, and used for performing power state monitoring and data processing on a main power source of a server, the phase change memory is connected with the FPGA and used for saving MEMORY stored data in the DRAM before the server is powered off, the FPGA is used for transmitting data in a conversion server,the DRAM is used for retrieving data by the central processing unit and the FPGA before the server is powered off, and the standby power supply is used for supplying power after the main power sourceof the server is powered off. According to the heterogeneous storage device, a PCM saves the data processed in real time by the DRAM, after a system is powered on and restarted, the system firstly recovers the data in the PCM to ensure that the data is not lost even if there is a failure in the server system, work efficiency is improved, and the reliability of the server is enhanced.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a phase-change memory-based heterogeneous storage device and method. Background technique [0002] With the rapid development of the economy and society, my country is about to usher in the Internet + era. The advent of the Internet + era is accompanied by the rapid rise of the server industry. Massive data is impacting various industries with an unprecedented growth trend. The maintainability of IT infrastructure Higher requirements have also been raised. With its excellent performance, servers are widely used in cloud computing, big data processing, network platforms and other fields, and are favored by the market. [0003] At present, in the process of designing and using the server, people usually use DRAM (ie, Dynamic Random Access Memory) to save Cache cache data. Since DRAM is a volatile storage medium, the cached data stored in DRAM will disappear after the s...

Problems solved by technology

[0004] The reliability requirements of the server are getting higher and higher, and data protection is particularly important. When the server system is abnormally powered off, even if the data processed in the DRAM memory will be permanently lost due to the power failure, it cannot be recovered after the server is restarted.
