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.


Original Abstract Submitted

the present application discloses a processing method for a brute force hot unplug operation on a u.2 nvme solid-state disk, including: 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, where an 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; and 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.
