Abstract

The invention provides a writing-in method for storage data in a storage system, which comprises the following steps: a user-mode file system receives a writing-in request; processing the storage dataaccording to the writing-in request, and constructing metadata corresponding to the storage data; and writing the storage data and metadata in a nonvolatile memory. By establishing the user-mode filesystem, the distributed storage system does not need to convert the user mode to a kernel mode when reading local storage data, avoids a large number of I / O operations when the user mode is convertedto the kernel mode, and simplifies the I / O process. Moreover, in the process of writing in data, the metadata corresponding to the data is constructed by the user-mode file system, which facilitatesthe access of metadata, improves the performance utilization of the non-volatile memory, and thus improves the overall data reading and writing performance of the storage system. The present application also provides a writing-in system for storage data in a storage system, a computer-readable storage medium and a server having the above-mentioned beneficial effects.

Description

technical field [0001] The present application relates to the field of storage, and in particular to a method for writing data stored in a storage system, a writing system, a computer-readable storage medium, and a server. Background technique [0002] In recent years, nonvolatile memory (nonvolatile memory, NVM) technology has developed rapidly, and new types of nonvolatile memory provide memory-level persistent data storage media. [0003] In the field of distributed storage, non-volatile memory also provides a new solution to improve system performance. However, introducing a non-volatile memory into a traditional distributed storage system can only bring limited improvement to system performance, and can only play a part of the performance of the non-volatile memory. [0004] This is because traditional distributed storage systems are all based on disk (HDD) designs, and the low speed of disks leads to complex software layers including the operating system kernel. When...
