# Used to build an additional object ring for a storage policy.
# The namevar/name of this class must be an integer.
#
# Specifies the following relationship:
# Rings should be created before any devices are added to them
# Rings should be rebalanced if anything changes
#
# == Parameters
# [*policy_id*]
# (required) The id must be a positive integer. This is used to denote
# the storage policy ID for the object ring.
# Defaults to $name
#
# [*part_power*]
# (optional) The total number of partitions that should exist in the ring.
# This is expressed as a power of 2.
#
# [*replicas*]
# (optional) Number of replicas that should be maintained of each stored
# object.
#
# [*min_part_hours*]
# (optional) Minimum amount of time before partitions can be moved.
#
# == Dependencies
