== Transport Types ==

RDMA can transport data reliably or unreliably over the Reliably Connected (RC) and Unreliable Datagram (UD) transport protocols, respectively. The former has the benefit of preserving requests (no requests are lost), while the latter requires fewer queue pairs when handling multiple connections. This is due to the fact that UD is connection-less, allowing a single host to communicate with any other using a single queue .<ref>Storm: a fast transactional dataplane for remote data structures: https://dl.acm.org/doi/pdf/10.1145/3319647.3325827</ref>.
