The embodiment of the present invention discloses a PCIE Switch-based bandwidth recovery method, device and medium to obtain the cable connection status and link bandwidth of the downlink port; when it is detected that the cable connection status and link bandwidth of the downlink port meet the recovery conditions , the connection flag in the connection control register can be adjusted to the first state, so as to trigger the system to remove the cable connected to the downlink port. The effect of cable removal is achieved through software simulation. After the trigger system removes the cable connected to the downlink port, the connection flag in the connection control register can be adjusted to the second state again to trigger the system to rejoin the cable connected to the downlink port. At this time, the system can recognize All the cables connected to the downlink port, so that the link bandwidth of the downlink port matches the number of cables actually connected to the downlink port, which solves the problem that the specified link bandwidth cannot be formed when multiple cables are connected.
Description
technical field [0001] The present invention relates to the technical field of storage systems, in particular to a PCIE Switch-based bandwidth recovery method, device and computer-readable storage medium. Background technique [0002] In recent years, with the continuous improvement of users' requirements for integration, unification, efficiency, space, and energy consumption, there are many new scenarios for the use of PCIE Switch. One of the scenarios is: a bandwidth of PCIE Switch is x16 downlink port, which needs to pass through four MiniSAS cables are connected to form x16 bandwidth links, and the cables support hot swapping. [0003] During use, the cables are inserted one by one in sequence. After inserting the first cable, the PCIE link will automatically negotiate, and the link bandwidth after negotiation is x4. When the remaining three cables are inserted later, due to the PCIE specification, the PCIE link will not automatically negotiate, and the bandwidth will a...
