- Thin-provisioned FlashCopy
You can have a mix of thin-provisioned and fully allocated volumes in FlashCopy® mappings. One common combination is a fully allocated source with a thin-provisioned target, which enables the target to consume a smaller amount of real storage than the source. - Grains and the FlashCopy bitmap
When data is copied between volumes, it is copied in units of address space known as grains. - FlashCopy mapping events
FlashCopy mapping events detail the events that modify the state of a FlashCopy mapping.
