lose 4 disks and still recover
your data and your overhead would be 1.4 (14/10) as opposed to triple
replication of 3 (3/1)

1) Swift doesn't yet currently support erasure codes. It's something we're
actively working on now.
2) It depends. Swift will allow you to choose your EC algorithm and the
parameters for it, so that will be what determines how much raw storage space
is needed for a given amount of usable storag
With a 100% 'Erasure Code' policy how much extra storage is needed to
satisfy a 1PB usable cluster ?
