Understanding the Software Configurations
Understanding Giant Domains (Full Rack)
These topics provide information on the Giant Domain configuration for the Full Rack:
■
“Percentage of CPU and Memory Resource Allocation” on page 72
■
“Management Network” on page 72
■
“10-GbE Client Access Network” on page 72
■
“InfiniBand Network” on page 73
Percentage of CPU and Memory Resource Allocation
One domain is set up on each SPARC T5-8 server in this configuration, taking up 100% of the
server. Therefore, 100% of the CPU and memory resources are allocated to this single domain
on each server (all eight sockets).
Note - You can use the CPU/Memory tool (setcoremem) to change this default allocation
after the initial installation of your system, if you want to have some CPU or memory
resources parked (unused). See “Configuring CPU and Memory Resources (
osc-
setcoremem
)” on page 170 for more information.
Management Network
Two out of the four 1-GbE host management ports are part of one IPMP group for this domain:
■
NET0
■
NET3
10-GbE Client Access Network
All eight PCI root complex pairs, and therefore eight 10-GbE NICs, are associated with the
logical domain on the server in this configuration. However, only two of the eight 10-GbE NICs
are used with this domain. One port is used on each dual-ported 10-GbE NIC. The two ports on
the two separate 10-GbE NICs would be part of one IPMP group. One port from the dual-ported
10-GbE NICs is connected to the 10-GbE network in this case, with the remaining unused ports
and 10-GbE NICs unconnected.
The following 10-GbE NICs and ports are used for connection to the client access network for
this configuration:
■
PCIe slot 1, port 0 (active)
■
PCIe slot 14, port 1 (standby)
