Background technique

In the field of general server technology, server products have various topologies, and different topologies correspond to different hard disk sequences.

Generally, a server can be connected to multiple backplanes, and each backplane has multiple backplane physical slots for connecting physical hard disks. In practical applications, the user divides all storage spaces in the server into different physical drive letters, so that one physical hard disk may correspond to multiple system drive letters. When the system drive letter needs to be adjusted or fails, technicians need to search for the corresponding physical hard disk in the server chassis based on work experience and professional knowledge, and repair the physical slot on the backplane to which the physical hard disk is connected. Among them, because the technicians lack a reliable basis in the maintenance process and cannot directly find the corresponding physical hard disk, the maintenance work efficiency is slow.

On the other hand, when making a design scheme, if the corresponding relationship between the backplane physical slot and the system drive letter can be determined and recorded in time, it can provide a reference for the applicability of the design scheme; The corresponding relationship between the bit and the system drive letter determines whether the current design scheme meets the expected expectations and whether it needs to be adjusted.
