1 – Introduction Interoperability

InfiniPath OpenFabrics software is interoperable with other vendors’ InfiniBand Host Channel Adapters (HCAs) running compatible OpenFabrics releases. There are several options for subnet management in your cluster:

„Use the embedded Subnet Manager (SM) in one or more managed switches supplied by your InfiniBand switch vendor.

„Use the Open source Subnet Manager (OpenSM) component of OpenFabrics.

„Use a host-based Subnet Manager.

Interoperability

QLogic InfiniPath participates in the standard InfiniBand subnet management protocols for configuration and monitoring. Note that:

„InfiniPath OpenFabrics (including Internet Protocol over InfiniBand (IPoIB)) is interoperable with other vendors’ InfiniBand HCAs running compatible OpenFabrics releases.

„The QLogic MPI and Ethernet emulation stacks (ipath_ether) are not interoperable with other InfiniBand HCAs and Target Channel Adapters (TCAs). Instead, InfiniPath uses an InfiniBand-compliant, vendor-specific protocol that is highly optimized for MPI and Transmission Control Protocol (TCP) between InfiniPath-equipped hosts.

NOTE:

See the OpenFabrics web site at www.openfabrics.org for more information on the OpenFabrics Alliance.
