==PROCESSING METHOD, APPARATUS, AND SYSTEM FOR BRUTE FORCE HOT UNPLUG OPERATION ON SOLID STATE DISK, AND MEDIUM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240045748 titled 'PROCESSING METHOD, APPARATUS, AND SYSTEM FOR BRUTE FORCE HOT UNPLUG OPERATION ON SOLID STATE DISK, AND MEDIUM

==Simplified Explanation==

The present application discloses a processing method for a brute force hot unplug operation on a U.2 NVMe solid-state disk. The method includes the following steps:

* Predefining a short signal pin for detecting whether an NVMe solid-state disk is in place.
* Presetting to trigger an operation of calling a SMI program according to input state change information of GPIO of a PCH chip. The input state value of the GPIO is determined according to a connection state of the short signal pin and a U.2 slot.
* Calling the SMI program when a change in an input state of the GPIO is detected, and reading the input state value of the GPIO.
* Breaking a link between a PCIe root bridge and the NVMe solid-state disk by using the SMI program if the input state value of the GPIO is a corresponding value about the NVMe solid-state disk not in place.

Potential applications of this technology:

* Data centers and server environments where hot unplug operations on NVMe solid-state disks are required.
* High-performance computing systems that utilize NVMe solid-state disks.

Problems solved by this technology:

* Simplifies the process of performing a hot unplug operation on a U.2 NVMe solid-state disk.
* Provides a reliable method for detecting the presence or absence of an NVMe solid-state disk.
* Ensures the proper disconnection of the NVMe solid-state disk from the PCIe root bridge.

Benefits of this technology:

* Reduces the risk of data corruption or loss during hot unplug operations.
* Improves the efficiency and ease of maintenance in data center and server environments.
* Enhances the overall reliability and stability of systems utilizing NVMe solid-state disks.
