InfiniBand is fairly cheap. However, true IB for RAC (uDAPL) is not supported in 10gR2. As far as we've been able to figure out, the InfiniBand support is for SDP and is undocumented (that's for SQL*Net) and for interconnect traffic is only IPoIB - standard IP run over InfiniBand. Oracle has dropped plans to support uDAPL - apparently deciding to try to push their own proprietary RDMA protocol.
