Pete Zaitcev 2016-07-22 21:36:32 UTC Doc Text Feature: Improved replica placement and protection from duplicated assignments

Reason: In the traditional Swift layout, accidentally assigning two repricas of a partition to the same device results in a silent reduction of durability.

Result: Duplicate assignments are prevented, thus adhering to calculated guarantees. However, since obviously this requires the number of devices to be no less than the number of replicas, it is possible for certain incorrect old rings to be considered invalid. It is still possible to have the number of zones smaller than number of replicas.

This enhancement adds improved replica placement, and protection from duplicated assignments.
