InfiniBand Network Data Paths for a Database Domain
Note - The information in this section applies to a Database Domain that is either a dedicated
domain or a Database I/O Domain.
When a Database Domain is created on a SPARC T5-8 server, the Database Domain has the
following InfiniBand paths:
■
SPARC T5-8 server to both Sun Datacenter InfiniBand Switch 36 leaf switches
■
SPARC T5-8 server to each Exadata Storage Server, through the 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
The number of InfiniBand HCAs that are assigned to the Database Domain varies, depending
on the type of configuration that is set up on the SPARC T5-8 server.
For the InfiniBand HCAs assigned to a Database Domain, the following InfiniBand private
networks are used:
■
Storage private network: One InfiniBand private network for the Database Domains to
communicate with each other and with the Application Domains running Oracle Solaris 10,
and with the ZFS storage appliance
■
Exadata private network: One InfiniBand private network for the Oracle Database 11g
Real Application Clusters (Oracle RAC) interconnects, and for communication between the
Database Domains and the Exadata Storage Servers
The two ports on each InfiniBand HCA 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.
InfiniBand Network Data Paths for an Application Domain
Note - The information in this section applies to an Application Domain that is either a
dedicated domain or an Application I/O Domain.
