You can divide the server into one to four PDomains, depending on your application
requirements. For example, you can divide the server into four PDomains, each
running its own applications. Or, you can configure the server into one PDomain to
provide all of the hardware resources to a single set of applications.
The server comes preconfigured as one PDomain (not bounded), containing all of the
hardware resources.
There are two types of PDomains:

Bounded PDomain

Description
A Bounded PDomain contains only one DCU and has total hardware
isolation from other PDomains in the server. Bounded PDomains
performance might be better when compared to PDomains.
A PDomain can contain one to four DCUs. In a multiple DCU
PDomain, processor data traffic between the DCUs is routed through
the SSBs, so PDomains might have lower performance compared to a
Bounded PDomain.
