There are several maps in a Ceph cluster, such as a cluster map, an object storage daemon (OSD) map for a list of OSDs, a monitor map for known monitor nodes, a placement group (PG) map for the location of objects or data chunks, and a CRUSH map to determine how to store and retrieve data by computing the data storage location.
