OFED Support

The OpenFabrics Enterprise Distribution (OFED) 2.0 stack is integrated with UEK R4, and supports all Oracle branded InfiniBand (IB) hardware, on systems with an x86-64 architecture. This includes:

  • Reliable Datagram Sockets (RDS) is a high-performance, low-latency, reliable connectionless protocol for datagram delivery

  • Sockets Direct Protocol (SDP) supports stream sockets for RDMA network fabrics

  • Ethernet over InfiniBand (EoIB)

  • Internet Protocol over InfiniBand (IPoIB)


Ethernet tunneling over IPoIB (eIPoIB) is not supported with UEK R4.

OFED 2.0 supports the following RDS features with UEK R4:

  • Async Send (AS)

  • Quality of Service (QoS)

  • Active Bonding (AB)

  • Netfilter (NF)

  • Shared Request Queue (SRQ)


Automatic Path Migration (APM) is not supported with UEK R4.

Support for IB, OFED, and RDS is integrated into the kernel. The OFED user-space RPMs continue to be provided, but the kernel-ib and ofa-kernel RPMs are not required.
