PowerShell: Dell server hardware audit via iDrac API (Redfish)

I have revisited this issue here:

Here is a simple hardware audit using the RedFish API that is part of Dell iDrac. This is a phase 1 of what will be a far more useful estate wide audit function that I am working on.

The code return a small summary of the data it collects to the screen. If you want more then have a look what is stored in this variable:

$serveridracinfoJSON

As usual, please reach out to me if you have questions/edits, or leave something in the comments.
