RoCEE (RDMA over Converged Enhanced Ethernet) is a protocol that implements Remote Direct Memory Access (RDMA) over 10 Gigabit Ethernet networks. It allows you to maintain a consistent, high-speed environment in your data centers while providing deterministic, low latency data transport for critical transactions.
High Performance Networking (HPN) is a set of shared libraries that provides RoCEE interfaces into the kernel. Instead of going through an independent network infrastructure, HPN places data directly into remote system memory using standard 10 Gigabit Ethernet infrastructure, resulting in less CPU overhead and reduced infrastructure costs.
Support for RoCEE and HPN under Red Hat Enterprise Linux for Real Time does not differ from the support offered under Red Hat Enterprise Linux 7.
