How To Install Infiniband Driver

The InfiniBand technique is not used for general network connectivity, and its main design is to address the connection problem on the server side. Thus, InfiniBand technology will be applied to the server and the server (such as replication, distributed work.), servers and storage devices (such as SAN and direct the accessories) as well as between the server and network communications (such as LAN , WANs and Internet). The mainstream InfiniBand technology comes in two flavors.
