Understanding the Network Requirements
Each SPARC T5-8 server and 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.
Note - The SPARC T5-8 servers have four 1-GbE host management interfaces (NET 0
- NET3). All four NET interfaces are physically connected, and use IPMP to provide
redundancy. See “Understanding the Software Configurations” on page 46 for more
information.
The method used to connect the ZFS storage controllers to the management network varies
depending on the controller:
■
Storage controller 1: NET0 used to provide access to the Oracle ILOM network using
sideband management, as well as access to the 1-GbE host management network.
■
Storage controller 2: NET0 used to provide access to the Oracle ILOM network using
sideband management, and NET1 used to provide access to the 1-GbE host management
network.
Oracle SuperCluster T5-8 is delivered with the 1-GbE host management and Oracle ILOM
interfaces connected to the Ethernet switch on the rack. The 1-GbE host management
interfaces on the SPARC T5-8 servers should not be used for client or application network
traffic. Cabling or configuration changes to these interfaces is not permitted.
■
Client access network – This required 10-GbE network connects the SPARC T5-8 servers
to your existing client network and is used for client access to the servers. Database
applications access the database through this network using Single Client Access Name
(SCAN) and Oracle RAC Virtual IP (VIP) addresses.
■
InfiniBand private network – This network connects the SPARC T5-8 servers, ZFS
storage appliance, and Exadata Storage Servers using the InfiniBand switches on the rack.
For SPARC T5-8 servers configured with Database Domains, Oracle Database uses this
network for Oracle RAC cluster interconnect traffic and for accessing data on Exadata
Storage Servers and the ZFS storage appliance. For SPARC T5-8 servers configured with
the Application Domain, Oracle Solaris Cluster uses this network for cluster interconnect
traffic and to access data on the ZFS storage appliance. This non-routable network is fully
contained in Oracle SuperCluster T5-8, and does not connect to your existing network. This
network is automatically configured during installation.
Note - All networks must be on distinct and separate subnets from each other.
The following figure shows the default network diagram.
