Understanding the Software Configurations
■
Storage private network: Connections through P1 (active) on the InfiniBand HCA
associated with the first CPU in the domain and P0 (standby) on the InfiniBand HCA
associated with the second CPU in the domain.
For example, for the first Medium Domain in a Full Rack, these connections would be
through P1 on the InfiniBand HCA installed in slot 3 (active) and P0 on the InfiniBand
HCA installed in slot 11 (standby).
■
Exadata private network: Connections through P0 (active) and P1 (standby) on all
InfiniBand HCAs associated with the domain.
For example, for the first Medium Domain in a Full Rack, connections would be made
through both InfiniBand HCAs (slot 3 and slot 11), with P0 on each as the active
connection and P1 on each as the standby connection.

InfiniBand HCA associated with the first CPU in the domain and P1 (standby) on the
InfiniBand HCA associated with the second CPU in the domain.
For example, for first Medium Domain in a Full Rack, these connections would be

HCA installed in slot 11 (standby).
Understanding Small Domains (Full Rack)
Note - If you have the Full Rack, you cannot install a Fibre Channel PCIe card in a slot that
is associated with a Small Domain. In Full Rack configurations, Fibre Channel PCIe cards
can only be added to domains with more than one 10-GbE NIC. One 10-GbE NIC must be
left for connectivity to the client access network, but for domains with more than one 10-GbE
NICs, other 10-GbE NICs can be replaced with Fibre Channel HBAs. See “Understanding
Full Rack Configurations” on page 69 for more information on the configurations with
Small Domains and “Using an Optional Fibre Channel PCIe Card” on page 139 for more
information on the Fibre Channel PCIe card.
These topics provide information on the Small Domain configuration for the Full Rack:
