3.4. Infiniband
Infiniband is a type of communications architecture often used to increase bandwidth and provide quality of service and failover. It can also be used to improve latency through Remote Direct Memory Access (RDMA) capabilities.
Support for Infiniband under Red Hat Enterprise Linux for Real Time does not differ from the support offered under Red Hat Enterprise Linux 7.
