Understanding the Hardware Components and Connections
1-GbE Host Management Network Physical Connections (Exadata
Storage Servers)
Each Exadata Storage Server connects to the 1-GbE host management network through the 1-
GbE host management port (NET 0 port) at the rear of each Exadata Storage Server. One IP
address is required for 1-GbE host management for each Exadata Storage Server.
Understanding the ZFS Storage Appliance Physical
Connections
The ZFS storage appliance has five sets of physical connections:

InfiniBand Private Network Physical Connections (ZFS Storage
Appliance)
The ZFS storage appliance connects to the InfiniBand private network through one of the
two ZFS storage controllers. The ZFS storage controller contains one Sun Dual Port 40Gb
InfiniBand QDR HCA. The two ports in each InfiniBand HCA are bonded together to increase
available bandwidth. When bonded, the two ports appear as a single port, with a single IP
address assigned to the two bonded ports, resulting in one IP address for InfiniBand private
network connections for the ZFS storage controller.
The two ports in the InfiniBand HCA connect to a different leaf switch to provide redundancy
between the ZFS storage controller and the leaf switches. The following figures show how
redundancy is achieved with the InfiniBand connections between the ZFS storage controller and
the leaf switches in the Full Rack and Half Rack configurations.
