Introduction
Interoperability
IB0056101-00 G.02 Preliminary 1-3
A
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.
