Supported Domain Configurations
Use this table to identify your SuperCluster configuration, then review the supported resource
allocation activities.
Note - A dedicated domain can be any Application or Database Domain that is not associated
with I/O Domains. For more information about the different types of SuperCluster domains, see
“Understanding the Software Configurations” on page 46.

Plan how the CPU and memory resources are allocated
to the domains.
“Plan CPU and Memory
Allocations” on page 175
Reallocate all of the resources across domains at the
socket or core level (a reboot is required if primary
domain resources are changed).
“Change CPU/Memory Allocations (Socket
Granularity)” on page 182
“Change CPU/Memory Allocations (Core
Granularity)” on page 186
Remove (park) resources from dedicated domains for
licensing purposes.
Note - Parked resources are not available for use by any
domains.
“Park Cores and Memory” on page 190
Revert to a previous resource configuration. “Revert to a Previous CPU/Memory
Configuration” on page 201
All domains are dedicated

Mixed domains – some are
dedicated, some are Root
Domains
Activities you can only perform at initial installation,
before any I/O Domains are created:
