Problems solved by technology
These tasks must be done manually by an experienced system administrator, which requires a lot of effort
[0006] Therefore, for the above problems, a challenging problem is that software IO protocol stacks and applications are usually very complex
And another challenging problem is: there are quite a lot of different types of PCIE devices
Therefore, it is extremely difficult to use a unified software framework and user interface to manage hot-plug activities of all types of PCIE devices

A system and method for managing hot plugging of Peripheral Component Interconnect Express (PCIE) devices is provided. In one embodiment according to the present disclosure, the system includes: a user command interface module, a hot-swap management module, and a hot-swap interface library. The user command interface module is configured to provide an interface for the user to input operation commands. The hot-swap management module is configured to respond to an operation command from a user, by means of an interface provided by the operating system, a kernel of the operating system, and at least one of the corresponding hot-swap group service modules among the plurality of hot-swap group service modules , to execute the operation command. The hot-swap interface library is configured to provide an interface for interacting with the hot-swap management module. Through the embodiments of the present disclosure, a new architecture for hot plugging of PCIE devices is provided, which can realize the automation of hot plugging operations of PCIE devices, significantly simplify user operations, improve operating efficiency, and improve user experience.
Description
technical field [0001] Embodiments of the present disclosure relate to the technical field of device hot plugging, and more particularly to systems, methods and computer program products for managing peripheral component interconnect express (PCIE) device hot plugging. Background technique [0002] Currently, support for hot swapping of hardware devices is quite popular. For example, in various electronic devices such as personal computers, most hardware supports hot plugging. Hot swapping refers to adding or removing hardware devices (such as PCIE cards, network interface cards (NICs), host bus adapters (HBAs), etc.) in the system without shutting down the system or cutting off the power supply. Removed technology. Hot swap is one of the key technologies to improve system availability and maintainability. No matter for a general server or a storage device, the hot plugging is required. Also, repair service teams often expect devices to support hot-swapping capabilities,...
