Hello

I am trying to find some information on the relationship of the ring 
(builder) structure of swift and the size of disks used, i.e. how is 
capacity of a disk managed.
I've seen many docs/blogs explaining the ring and partitions but I have 
not seen any info on how available space per disk is managed, i.e. the 
relationship between disk size and allocating ring partitions.

Do all disks in a ring need to be of the same capacity? If not how is 
swift handling the amount of free space?

Any pointers to documentation on this?
