Abstract

The invention relates to the technical field of storage, in particular to a performance improvement method and device for distributed storage equipment and the distributed storage equipment. Accordingto the method, a Bcache disk is used in the Bluestore, and a relatively standard B+ tree is used as an index, so that the hit rate is greatly improved, the SSD performance is exerted to the greatestextent, and the service life of the SSD is also protected, namely, the affinity to an SSD flash memory medium is relatively good. The overall performance of a Bluestore storage engine mode can be improved in a hybrid disk scene.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method and device for improving performance of a distributed storage device, and a distributed storage device. Background technique [0002] During the rapid development of distributed storage devices, filestore and bluestore storage engines were born. Filestore was only designed for mechanical disks at the beginning, and did not specifically consider optimization for ssd. Therefore, the original intention of bluestore was to reduce write amplification and target ssd. Do optimization, and directly manage the bare disk, theoretically further reduce the overhead of file systems such as ext4 / xfs. However, using the bluestore storage engine discards the original journal mechanism, but the performance of the bluestore storage engine is not high in SSD and HDD mixed mode scenarios. Contents of the invention [0003] Aiming at the problem of low performance of the bluestor...
