Vnic binding method for multiple infiniband gateways

Abstract

The present invention provides a vNIC binding method for multiple Infiniband gateways, which uses identification information of gateways to distinguish different vNICs virtualized by multiple Infiniband gateways, and binds the distinguished vNICs to specific IP information, so that different IP segments Transmission through a certain gateway, thus realizing the multiplication of the bandwidth between the Infiniband network and the Ethernet network, breaking through the bottleneck between the Infiniband network and the Ethernet network, and realizing high-speed data exchange between different types of networks, and in the application according to Different machine names corresponding to different IP network segments are used to select IP network segments and passed Infiniband gateways to achieve load balancing of multiple Infiniband gateways, especially in big data application environments such as seismic data processing.

Description

technical field [0001] The invention relates to a vNIC binding technology in an Infiniband gateway environment, in particular to a vNIC (Virtual Network Interface Card, virtual network adapter) binding method of multiple Infiniband gateways. Background technique [0002] With the development of petroleum geophysical exploration technology, seismic exploration methods are developing in the direction of multi-dimensional, multi-component, and ultra-multi-trace. Currently, the main construction method is 1ms or 2ms sampling and the number of receiving traces is less than 5000. According to 1ms sampling and 5000 channel receiving calculations, the real-time data flow is about 20MB / s. If it is continuous acquisition (such as air gun operations at sea), the storage data speed must be above 20MB / s. According to the development trend of seismic exploration towards full wave field and high-density acquisition, perhaps in the near future, 10,000 or 20,000 channels will be sampled in 1...

On the other hand, the development of the data center now makes the network architecture of the cluster not only limited to the Ethernet network, but also the Infiniband network, and the large-scale storage resource devices used by the cluster may be stored in the Ethernet or in the Infiniband network. , so how to realize the sharing of different storage resources in the Ethernet and Infiniband networks, and at the same time satisfy the rapid transmission of terabytes of data is a difficult challenge and an important issue for the current geophysical exploration data center

[0004] At present, the existing single Infiniband gateway vNIC binding technology can realize the integration of Infiniband network and Ethernet, but because it can only realize the vNIC binding of one Infiniband gateway, all data transmission between Ethernet and Infiniband network can only be through This will greatly limit the data transmission bandwidth between the two networks, especially when the Ethernet network and the Infiniband network are relatively large data centers, this network bandwidth bottleneck is particularly obvious, and in the seismic data processing data center, Due to the large amount of data, many concurrent data accesses, and high concurrency, network congestion often occurs between the Ethernet network and the Infiniband network, resulting in large data transmission delays and even network interruptions, which greatly affects the data center. Cluster operation and business processing limit the development of data centers
