Table II.2 – Preparing a physical machine – use case
Title Preparing a physical machine

Description A cloud service operations manager installs multiple processing units on the backplane of an
enclosure to increase the computing resources of a physical machine. He or she also installs
more than one storage device per CPU in a processing unit through standard storage
interfaces.
To connect all multiple processing units together, a cloud service operations manager
mounts a switch device which is responsible for system interconnects and network topology
to the backplane of the enclosure.
In addition, the enclosure is equipped with a power supply to provide power to an entire
physical machine and a cooling device to reduce heating. A cloud service operations manager
should be able to check whether each device is installed in a physical machine correctly
through a console panel on the enclosure.
System software and operating systems are installed on corresponding devices or rebooted
and consequently a physical machine completes to set up its operations.
Based on the above steps to construct a physical machine, several physical machines are
connected with each other by their external interfaces and can be installed in a standard
rack.

Roles/sub-roles CSP: cloud service operations manager.
