The Oracle Exadata Storage Expansion Rack includes Exadata Storage Servers, as well as equipment to connect the servers to your network. The network connections enable the servers to be administered remotely.
Each Exadata Storage Server consists of the following network components and interfaces:
1 embedded Gigabit Ethernet port (NET0) for connection to the host management network
1 dual-ported Sun QDR InfiniBand PCIe Low Profile host channel adapter (HCA) for connection to the InfiniBand private network
1 Ethernet port (NET MGT) for Oracle ILOM remote management
The Cisco Catalyst 4948 Ethernet switch supplied with the Oracle Exadata Storage Expansion Rack is minimally configured during installation. The minimal configuration disables IP routing, and sets the following:
Host name
IP address
Subnet mask
Default gateway
Domain name
Domain Name Server
NTP server
Time
Time zone
To deploy the Oracle Exadata Storage Expansion Rack, ensure that you meet the minimum network requirements. There are two networks used for the Oracle Exadata Storage Expansion Rack. Each network must be on a distinct and separate subnet from the others. The network descriptions are as follows:
Management network – This required network connects to your existing management network, and is used for administrative work for the Exadata Storage Servers. It connects the servers, Oracle ILOM, and switches connected to the Ethernet switch in the rack. There is one uplink from the Ethernet switch in the rack to your existing management network.
Each Exadata Storage Server use two network interfaces for management. One provides management access to the operating system through the 1 GbE host management interface(s), and the other provides access to the Oracle Integrated Lights Out Manager through the Oracle ILOM Ethernet interface.
InfiniBand private network – This network connects the Exadata Storage Servers using the InfiniBand switches on the rack. This non-routable network is fully contained in the Oracle Exadata Storage Expansion Rack, and does not connect to your existing network. This network is automatically configured during installation.
