A SPARC M7-16 server PDomain operates like an independent server that has full hardware isolation from other PDomains in the server. For example, you can reboot one PDomain while the other PDomains on a server continue to operate.
You can configure a SPARC M7-16 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.
