Understanding the Software Configurations
So, for the first Medium Domain in a Half Rack, connections would be made through
both InfiniBand HCAs (slot 3 and slot 11), with P0 on each as the active connection and
P1 on each as the standby connection.
■
Application Domain:
■
Storage private network: Connections through P1 (active) on the InfiniBand HCA
associated with the first CPU in the domain and P0 (standby) on the InfiniBand HCA
associated with the second CPU in the domain.
So, for the first Medium Domain in a Half Rack, these connections would be through
P1 on the InfiniBand HCA installed in slot 3 (active) and P0 on the InfiniBand HCA
installed in slot 11 (standby).
■
Oracle Solaris Cluster private network: Connections through P0 (active) on the
InfiniBand HCA associated with the first CPU in the domain and P1 (standby) on the
InfiniBand HCA associated with the second CPU in the domain.
So, for first Medium Domain in a Half Rack, these connections would be through P0 on
the InfiniBand HCA installed in slot 3 (active) and P1 on the InfiniBand HCA installed
in slot 11 (standby).

Percentage of CPU and Memory Resource Allocation
The amount of CPU and memory resources that you allocate to the logical domain varies,
depending on the size of the other domains that are also on the SPARC T5-8 server:
■
One Medium Domain and two Small Domains: The following options are available for CPU
and memory resource allocation:
■
Two sockets for the Medium Domain, one socket apiece for the two Small Domains
■
One socket for the Medium Domain, two sockets for the first Small Domain, one socket
for the second Small Domain
■
One socket for the Medium Domain and the first Small Domain, two sockets for the
second Small Domain
