An IB subnet can be partitioned for different customers or applications, giving security and quality of service guarantees. Each partition is identified by a PKEY (Partition Key). SDP (Sockets Direct Protocol) Use librdmacm (successor to rsockets and libspd) and LD_PRELOAD to intercept non-IB programs’ socket calls, and transparently (to the program) send them over IB via RDMA.
