text: To use these protocols, the system requires that a 25 Gbps Ethernet adapter is installed on 
  each node and dedicated RDMA-based ports are only configured for node-to-node 
  communication. 
  
  RDMA technologies, like RoCE and iWARP, enable the 25 Gbps Ethernet adapter to transfer 
  data directly between nodes, bypassing CPU, and caches, making transfers faster. 
  
  RDMA technologies provide faster connection and processing time than traditional iSCSI 
  connections and are a lower-cost option than Fibre Channel fabrics.
