Understanding the Software Configurations
Management Network Overview
The management network connects to your existing management network, and is used for
administrative work. Each SPARC T5-8 server provides access to the following management
networks:
■
Oracle Integrated Lights Out Manager (ILOM) management network – Connected through
the Oracle ILOM Ethernet interface on each SPARC T5-8 server. Connections to this
network are the same, regardless of the type of configuration that is set up on the SPARC
T5-8 server.
■
1-GbE host management network – Connected through the four 1-GbE host management
interfaces (NET0 - NET3) on each SPARC T5-8 server. Connections to this network will
vary, depending on the type of configuration that is set up on the system. In most cases, the
four 1-GbE host management ports at the rear of the SPARC T5-8 servers use IP network
multipathing (IPMP) to provide redundancy for the management network interfaces to the
logical domains. However, the ports that are grouped together, and whether IPMP is used,
varies depending on the type of configuration that is set up on the SPARC T5-8 server.
10-GbE Client Access Network Overview
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. 10-GbE NICs installed in the PCIe slots are
used for connection to this network. The number of 10-GbE NICs and the PCIe slots that they
are installed in varies depending on the type of configuration that is set up on the SPARC T5-8
server.
InfiniBand Network Overview
The InfiniBand network connects the SPARC T5-8 servers, ZFS storage appliance, and Exadata
Storage Servers using the InfiniBand switches on the rack. This non-routable network is fully
contained in Oracle SuperCluster T5-8, and does not connect to your existing network.
When Oracle SuperCluster T5-8 is configured with the appropriate types of domains, the
InfiniBand network is partitioned to define the data paths between the SPARC T5-8 servers, and
between the SPARC T5-8 servers and the storage appliances.
The defined InfiniBand data path coming out of the SPARC T5-8 servers varies, depending on
the type of domain created on each SPARC T5-8 server:
