Hi All,

Storage Insights allows you to view the capacity figures for an FS7x00.
I can't quite place one number: "Overhead Capacity".
The description is: "The amount of usable capacity occupied by metadata in a pool or system and other data used for system operation."

I'm struck by the large number, larger than, for example, "Usable Capacity." The Flashsystem is virtualized by an SVC.
What does this number represent? And where can I find more details about it?
