Embodiment Construction
[0041] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.
[0042] The embodiment of the present invention discloses a hot-swap method of a PCIe card, see figure 1 As shown, including:
[0043] S1: Judging whether the PCIe card is present in the bit signal and / or MRL lock signal;
[0044]S2: When the PCIe card exists in the bit signal and / or the MRL lock signal, the in bit signal and / or the MRL lock signal is acquired by the CPLD; when the PCIe card is not The in bit signal, the status signal of the PCIe card is acquired by the CPLD, as a bit signal of the PCIe card; when the ...

The application discloses a method for hot plugging a PCIE card, including: judging whether the PCIE card has an in-position signal and / or an MRL locking signal; when the PCIE card does not have an in-position signal or an MRL locking signal, Obtain or generate the in-position signal or MRL locking signal required by the hot-swap controller through CPLD; when the PCIE card has an in-position signal and / or MRL locking signal, obtain the in-position signal and / or MRL locking signal through CPLD Signal; obtain the POWER signal of the PCIE plug-in card through the CPLD; send the in-position signal, the MRL locking signal and the POWER signal to the hot-swap controller through the CPLD. Since the present invention considers various types of PCIE plug-in cards, various types of PCIE plug-in cards can be applied without changing the existing technical protocol of PCIE. The application also discloses a corresponding PCIE plug-in card hot-swap system, device and readable storage medium.
Description
Technical field [0001] The present invention relates to a hot-swap field, and more particularly to a hot-swap method, a system, apparatus, and a readable storage medium of a PCIe card. Background technique [0002] Hot swap, is a hardware management method that allows users to remove or replace components such as hard drives, power or cardboards such as hard drives, power or card boards without shutting down the power, thereby improving the timely recovery capabilities and scalability of disasters. And flexibility, etc. Especially in unified storage technology, data security is the core requirement of storage devices, so that the normal operation of ensuring that the equipment is constantly non-stop is the key to storage devices, so when a bad member is replaced, when the component needs to be replaced, the upgrade is, To ensure that the equipment is not stopping, the hot-swap technology works at this time, that is, replacing the fault accessories or adds new accessories in the s...
