"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0044] For the deployment of distributed storage systems, the relevant technical solutions are fragmented, providing commands and script tools for each stage, but no full-process package solutions for environmental checks, dependency tool installation, version conflicts, system performance verification, conflict resolution, etc. Operation and maintenance personnel need to rely on personal experience, pay attention to the running status of commands and scripts in real time, and provide response plans for possible errors.

[0045] Therefore, the relevant technical solutions have problems such as complicated steps, difficult data analysis, many service nodes, and difficult management.
