1 – Introduction
Interoperability
IB0056101-00 G 1-3
A
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.
