Plan CPU and Memory Allocations
■
Unallocated resources
– These resources are placed in the CPU and memory repositories
when Root Domains are created, or by leaving some resources unallocated when you use
the
osc-setcoremem
command.
In this example, the resources for the dedicated domains and the unallocated resources are
summed to provide total resources. The Root Domain resources are not included in total
resources.

Based on your site requirements, and the type and number of domains on
SuperCluster, decide how to allocate CPU and memory for each domain.
This is an example of a plan that reduces resources for
primary
,
ssccn2-dom2
,
ssccn2-dom4
,
so that the resources are parked (unallocated). The parked resources can later be used by I/O
Domains.
The total resources for before and after columns should match. This check ensures that all
resources are accounted for in your plan.
