The physical design provides the detailed specifications for purchasing hardware and ultimately deploying the solution.
The physical design is the last design. The physical design is based on the logical design. The physical design includes specific hardware from specific vendors. This design also lists specific configurations for each of the components that are deployed.
Example of a Physical Design:
The physical design describes implementation details based on the logical design. More than one physical design can be built based on a good quality logical design. Physical specifications can be recorded in a spreadsheet.
Although the logical design is useful for understanding and evaluating the design of the infrastructure, the physical design is more useful for purchasing hardware and building the infrastructure. For example, you can name specific host hardware, define PCI slot assignments, specify specific port connections, provide host name and IP address information, and choose operating system.
