Naming Conventions; Important Notes For Oracle Solaris Users; Network Connection And Ip Address Requirements - Oracle Exalogic Elastic Cloud Owner's Manual

6.2 Naming Conventions

The Exalogic machine name is used to generate host names for network interfaces for
all systems. For example, an Exalogic machine name of el01 will result in compute
node host names of el01cn01, el01cn02, el01cn03, and so on.
In a multirack configuration, each Exalogic rack name should be unique and identify
the rack. Oracle recommends using el01 for the first Exalogic rack, el02 for the
second, el03 for the third, and so on.

6.3 Important Notes for Oracle Solaris Users

If you are using the Oracle Solaris operating system on Exalogic compute nodes, keep
the following points in mind:
• BOND0 and BOND1, two important terms used in this guide, refer to the default
interfaces for IP over InfiniBand (IPoIB) and Ethernet over InfiniBand (EoIB),
respectively, on the Oracle Linux operating system.
• Oracle Solaris uses the IP Multipathing (IPMP) technology to support IPMP
Groups that consist of one or more physical interfaces on the same system that are
configured with the same IPMP group name. This technology provides the same
functionality as Bonded Interfaces on Oracle Linux. You can name the IPMP groups
anything. In this guide, BOND0 and BOND1 are used as example names to keep the
terminology consistent with Oracle Linux.

6.4 Network Connection and IP Address Requirements

This section describes the network connections required for multiple networks of
Exalogic machine. The network cables must be run from your network equipment to
the location of the Exalogic machine.
Note:
If you are using Oracle Solaris, you can assign the logical names of IPMP
groups to be ipmp0 or BOND0, and ipmp1 or BOND1 and have the name of
the datalink corresponding to the NET0 Ethernet port to be displayed as igp0
or net0 in the Solaris administration commands. For more information, see
IPMP Overview for Oracle Solaris
Note:
You can connect up to eight Exalogic machine full racks, or a combination of 4
Exalogic machine full racks and 4 Oracle Exadata Database Machine full racks
together on the same Infiniband fabric, without purchasing additional
hardware. To connect more machines, Oracle offers a choice of several high-
capacity datacenter switches which allow the creation of Exalogic clouds
comprising hundreds of racks and tens of thousands of processors
