In source code (https://github.com/openstack/swift/blob/master/bin/swift-ring-builder line 289) i found, that partitions count multiple 'replica_count' param only when i print information about ring. So, what 'partition_power' i should use for installation with, for example, 500 disks? And how much partitions are really placed on disks: 2^part_power or 2^port_power*replica_count ?
