WebThe IP over IB (IPoIB) ULP driver is a network interface implementation over InfiniBand. IPoIB encapsulates IP datagrams over an InfiniBand Connected or Datagram transport service. The IPoIB driver, ib_ipoib, exploits the following capabilities: VLAN simulation over an InfiniBand network via child interfaces. High Availability via Bonding. WebNo switch, direct connection. My understanding is that we stayed away from Infiniband due to cost. No, building an InfiniBand network is a lot cheaper (per Gb/s bisection bandwidth) than building and Ethernet+IP network. IB switches are a lot more simple than the Ethernet equivalents. (Of course I'm biased. ct corporation system sop
