Chapter 14 Clusters 243
In the figure, different virtual resources (vNICs and vHBAs) have been configured
on server profiles on two different Oracle Fabric Interconnnect chassis.
The flow of operation is as follows:
1. The XDS registers with SM.
2. The Oracle host drivers query SM for XDS location information.
3. The Oracle host drivers query XDS for the cluster (chassis) list. (This list
information is used by the host server to install virtual resources accordingly.)
OpenSM Decoupling
Xsigo’s OpenSM can be disabled and replaced by a third party Subnet Manager
(SM). Some customers prefer to use their own version of InfiniBand SM because it
includes custom extensions and can be managed externally to the Oracle Fabric
Interconnect.
