AI Technical Summary

Technical Problem

During the hot-swapping process of blade servers, a momentary power outage of the compute node may cause damage to the operating system and user data.

Method used

It adopts a hot-swappable auxiliary structure, including a tray, connector, disconnection module and trigger. The trigger is electrically connected to the disconnection module. When the tray is unlocked from the chassis, the disconnection module is activated to disconnect the server's data read and write operations, realizing hot-swapping without downtime.

Benefits of technology

It enables rapid hot-swapping of servers without affecting the operating system and user data integrity, thus improving operational efficiency.
