Problems solved by technology

However, when multiple hotresets are performed, there is a probability that the CPU and the Switch expansion chip cannot be negotiated to x8, and the negotiated bandwidth will be x1, x2, x4, etc., resulting in the process of establishing a cluster after the abnormal controller is repaired. Insufficient bandwidth, resulting in data loss

Embodiment 1

[0044] see figure 2 , figure 2 It is an implementation flow chart of a method for resetting the controller PCIE Switch expansion chip in the embodiment of the present invention, and the method may include the following steps:

[0045] S201: Receive a PCIE Switch extended chip reset request.

[0046] When an abnormality occurs in one of the mutually backup controllers, the abnormal controller generates a PCIESwitch expansion chip reset request, and sends a PCIE Switch expansion chip reset request to the normal controller, and the normal controller receives the PCIE Switch expansion chip reset ask.

[0047] In addition, the controllers that are mutual backups can also detect whether other controllers that constitute a backup relationship with themselves are abnormal, so that when the abnormal controller has a serious problem and cannot send out an abnormal prompt message, instead of Normal controllers that are mutually backed up can also detect abnormal situations in time. ...

Embodiment 2

[0056] see image 3 , image 3 Another implementation flowchart for the reset method of the controller PCIE Switch expansion chip in the embodiment of the present invention, the method may include the following steps:

[0057] S301: Receive a PCIE Switch extension chip reset request sent when an exception occurs at the backup controller side.

[0058] When an abnormality occurs in one of the mutually backup controllers, the abnormal controller generates a PCIESwitch expansion chip reset request. The backup controller is the abnormal controller, and it and the current normal controller are mutual backups. The backup controller sends a PCIE Switch extension chip reset request to its mutual backup normal controller, and the normal controller receives the PCIE Switch extension chip reset request sent when an exception occurs at the backup controller side.

Abstract

The invention discloses a reset method for a controller PCIE Switch extension chip. The method comprises the steps that a PCIE Switch extension chip reset request is received; PCIE Switch extension chip reset enabling information is generated; and the PCIE Switch extension chip reset enabling information is sent to a target PCIE Switch extension chip through a target complex programmable logic device so as to carry out reset operation on the target PCIE Switch extension chip. By applying the technical scheme provided by the embodiment of the invention, the reset efficiency of the Switch extension chip is improved, the probability of bandwidth insufficiency in the process of establishing a cluster after the abnormal controller is repaired is greatly reduced, and the data integrity is improved. The invention further discloses a reset device for a controller PCIE Switch extension chip, equipment and a storage medium, which have the corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a reset method, device, equipment and computer-readable storage medium for a controller PCIE Switch expansion chip. Background technique [0002] In the application of the storage server industry, it is necessary to use two or more controllers (Nodes) to work together, such as the QPI bus in the X86 architecture design of Intel / AMD. However, there is no such bus in some central processing units (CPU, Central Processing Unit), especially domestic CPU architectures (such as Phytium FT2000+ / 64-core ARM V8 architecture). If two controllers need to work together, another A non-transparent bridging (NTB, Non-Transparent Bridging) technology based on the PCI expansion bus (PCIE, Peripheral Component Interconnect Express), enabling direct communication between two motherboards (processors) with independent IO / Memory domains. [0003] see figure 1 , figure 1 It is...
