Problems solved by technology

[0006] The existing technology provides the interconnection between the Infiniband network and the Ethernet network to increase the bandwidth. The bonding technology is used to configure parameters for different network cards; to ensure that the physical port is in an active state, which does not improve the utilization of a separate Infiniband network.

Embodiment 1

[0036] A kind of redundant protection method that realizes dual-port Active-Active, it comprises the steps,

[0037] Infiniband network card physical port settings, dual-port Infiniband network card on the server, the corresponding physical ports of the Infiniband network card are mlx0 and mlx1;

[0038] Virtual interface setting; set virtual interfaces ib0 and ib1 through SR-IOV technology for physical port mlx0, and set virtual interfaces ib2 and ib3 for mlx1 through SR-IOV technology;

[0039] Formation of Bond port; use bonding technology to form virtual interface ib0 and ib2 to form bond0 port, and use bonding technology to form virtual interface ib1 and ib3 to form bond1 port;

[0040] The setting of the network port is to set the formed bond port as a different network port; to judge the state of the network port, if there is at least one physical port whose network port state is active, then the state of the network port corresponding to the two physical ports of the I...

Embodiment 2

[0051] On the basis of Embodiment 1, this embodiment also includes that when the physical port in the standby state returns to the active state, the network transmission of the network port is restored to the original physical port for transmission.

[0052] The physical port mlx0 is in the standby state, and the physical port mlx1 is in the active state. When the physical port mlx0 transmits, it transmits through the physical port mlx1; when the physical port mlx0 returns to the active state, it returns to the physical port mlx0 for transmission.

Embodiment 3

[0054] On the basis of Embodiment 1, a system based on the implementation of a dual-port Active-Active redundancy protection method in Embodiment 1, its

[0055] It includes servers, and each server is provided with two Infiniband network cards, wherein the corresponding physical ports of one Infiniband network card are respectively mlx0, and the corresponding physical ports of the other Infiniband network card are respectively mlx1, and it is characterized in that it also includes a virtual interface setting module and a bond port formation module, network port setting module and network switching module;

[0056] The virtual interface setting module sets virtual ports through SR-IOV technology for each network card; physical port ml0 sets virtual interfaces ib0 and ib1 through SR-IOV technology, and ml1 sets virtual interfaces ib2 and ib3 through SR-IOV technology;

[0057] The bond port formation module, through the bonding technology, the virtual interfaces ib0 and ib2 for...

Abstract

The invention relates to a Linux technology, and discloses a redundancy protection method and a redundancy protection system for dual-port Active-Active (Active-Active). Physical ports corresponding to an Infiniband network card are respectively mlx0 and mlx1, virtual interfaces ib0 and ib1 are set for the physical ports through an SR-IOV technology, and virtual interfaces ib2 and ib3 are set for the ml1; the virtual interfaces ib0 and ib2 are enabled to form a bod0 port through a bonding technology, and the virtual interfaces ib1 and ib3 are enabed to form a bod1 port; network ports are set, and the formed bond ports are set to be different network ports; and if at least one of the physical ports in different states is active, the two corresponding network ports are active. According to the invention, the network I / O continuity and the service continuity are ensured, and a higher network bandwidth is provided.

Description

technical field [0001] The invention relates to Linux technology, in particular to a dual-port Active-Active redundant protection method and system based on an Infiniband network. Background technique [0002] Currently on the market, Linux technology can only provide active-standby solutions for Infiniband network redundancy; this has a low utilization rate of network bandwidth and cannot well guarantee network continuity and service continuity. [0003] For increasing the bandwidth of the Infiniband network, the interconnection between the Infiniband network and the Ethernet network is used to increase the bandwidth, but it does not improve the utilization rate of a separate Infiniband network. [0004] The patent name is: vNIC binding method for multiple Infiniband gateways, the application number is: CN201310349336.4, the application date: 2013-08-12, and a vNIC binding method for multiple Infiniband gateways is disclosed in the patent application. The identification in...
