Example Embodiment

[0053] The present invention will be further explained below in conjunction with the drawings.

[0054] Such as figure 1 As shown, the embodiment of the reliability-based high-performance file system hybrid energy-saving storage system of the present invention includes an intermediate file system module, a hot data high-speed storage module, and a cold data storage module.

[0055] Such as figure 2 As shown, the middle-level file system module includes a permission module, a read-write module, a storage module, and an orientation module according to the data direction; the storage module is connected with an index module.

[0056] The intermediate file system module is mainly composed of the PLFS file system, and the orientation module includes algorithms for classifying and judging data access rates and energy-saving algorithms, classifying data into hot data with higher access rates and lower access rates Cold data. When a read / write request reaches the middle-level file system ...

Abstract

The invention relates to a mixed energy-saving memory system and method of a reliability-based high-performance file system. The system comprises an interlayer file system module, a hot data high speed memory module and a cold data memory module; the energy-saving memory frame of the invention adopts a parallel striped mode to store data, and guarantees the high performance and high reliability of the file system; simultaneously, the page view of the data file can be classified and reduced to hot data and cold data, the hot data with a higher visiting rate is stored into a data memory model with higher read-write performance, the cold data with a lower visiting rate is stored in a data memory module with common read-write performance, and the cold data memory module is closed to realize energy saving when the cold data is not visited. When the frame is applied to a server and a data center where the visiting rate is relatively concentrated on part of the data, a very good energy-saving effect can be obtained.

Description

technical field [0001] The invention relates to a hybrid energy-saving storage framework, in particular to a reliability-based high-performance file system hybrid energy-saving storage system and method. Background technique [0002] Glossary: [0003] PLFS file system: an open source parallel checkpoint storage file system, this design uses a file system developed independently based on its source code. [0004] PVFS file system: a parallel file storage system that provides RIAD-0 system structure. [0005] With the continuous development of science and technology, the continuous improvement of hardware performance, the performance of parallel storage systems is also changing rapidly, especially the access efficiency of parallel storage systems is outstanding. However, with the continuous upgrading of the performance of parallel storage systems and the continuous expansion of the scale of parallel systems, some issues that have not been paid attention to before have gradu...
