Note - The information in this section applies to an Application Domain that is either a dedicated domain or an Application I/O Domain.
Compute server to both IB leaf switches in the expansion rack
Compute server to the storage appliance, through the IB leaf switches in the expansion rack
The Application Domain does not access the storage servers, which are used only for the Database Domain.
The number of IB HCAs that are assigned to the Application Domain varies, depending on the type of configuration.
For the IB HCAs assigned to an Application Domain, the following IB private networks are used:
Storage private network: One IB private network for Application Domains to communicate with each other and with the Database Domains, and with the storage appliance
Oracle Solaris Cluster private network: Two IB private networks for the optional Oracle Solaris Cluster interconnects
The two ports on each IB HCA connects to different IB leaf switches to provide redundancy between the compute servers and the leaf switches.
