Understanding the Software Configurations
When an Application Domain is created on a SPARC T5-8 server (an Application Domain
running either Oracle Solaris 10 or Oracle Solaris 11), the Application Domain has the
following InfiniBand paths:
■
SPARC T5-8 server to both Sun Datacenter InfiniBand Switch 36 leaf switches
■
SPARC T5-8 server to the ZFS storage appliance, through the Sun Datacenter InfiniBand
Switch 36 leaf switches
Note that the Application Domain would not access the Exadata Storage Servers, which are
used only for the Database Domain.
The number of InfiniBand HCAs that are assigned to the Application Domain varies, depending
on the type of configuration that is set up on the SPARC T5-8 server.
For the InfiniBand HCAs assigned to an Application Domain, the following InfiniBand private
networks are used:
■
Storage private network: One InfiniBand private network for Application Domains to
communicate with each other and with the Database Domains, and with the ZFS storage
appliance
■
Oracle Solaris Cluster private network: Two InfiniBand private networks for the optional
Oracle Solaris Cluster interconnects
The two ports on each InfiniBand HCA will connect to different Sun Datacenter InfiniBand
Switch 36 leaf switches to provide redundancy between the SPARC T5-8 servers and the
leaf switches. For more information on the physical connections for the SPARC T5-8 servers
to the leaf switches, see “InfiniBand Private Network Physical Connections (SPARC T5-8
Servers)” on page 32.
Understanding Half Rack Configurations
In the Half Rack version of Oracle SuperCluster T5-8, each SPARC T5-8 server includes two
processor modules (PM0 and PM3), with two sockets or PCIe root complex pairs on each
processor module, for a total of four sockets or PCIe root complex pairs for each SPARC T5-8
server. You can therefore have from one to four logical domains on each SPARC T5-8 server in
a Half Rack.
These topics provide information on the domain configurations available for the Half Rack:
