1.7.3 IP Address Requirements for Oracle Exadata Database Machine
Oracle Exadata Database Machine requires a large number of host names and IP
addresses during initial configuration. The number of IP addresses required for a
particular network, such as the management network, depends on the type of system.
The network configuration, such as host names and IP addresses, used during
installation is generated from information when completing the Oracle Exadata
Database Machine Deployment Assistant.
Configure the new IP addresses in your existing networks only after you have run
Oracle Exadata Database Machine Deployment Assistant. All IP addresses in the
assistant-generated file must be unassigned at the time of initial configuration. In
addition, all IP addresses must be statically-assigned IP addresses, not dynamically-
assigned (DHCP) addresses.
All InfiniBand addresses must be in the same subnet, with a minimum subnet mask of
255.255.240.0 (or /20). The subnet mask chosen should be wide enough to
accommodate possible future expansion of the Oracle Exadata Database Machine
and InfiniBand network.
The following table lists the IP address requirements for Oracle Exadata Database
Machine X5-2 and later systems:
