Before starting the Object Storage services, you must create the initial
|
||||
account, container, and object rings. The ring builder creates configuration
|
||||
files that each node uses to determine and deploy the storage architecture.
|
||||
For simplicity, this guide uses one region and zone with 2^10 (1024) maximum

partitions, 3 replicas of each object, and 1 hour minimum time between moving

a partition more than once. For Object Storage, a partition indicates a

directory on a storage device rather than a conventional partition table.
