Introduction Interoperability

QLogic OFED 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 a host-based Subnet Manager. QLogic provides one, HSM, as a part of the InfiniBand fabric Suite download.

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

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 stack is not interoperable with other InfiniBand HCAs and Target Channel Adapters (TCAs). Instead, it uses an InfiniBand-compliant, vendor-specific protocol that is highly optimized for QLogic MPI and for MPI over verbs.

NOTE:

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