Explanation
This section provides explanatory and conceptual guides as well as a technical background on topics. It is meant to help you expand your knowledge of the Ceph ecosystem.
Ceph architecture
An overview of the general Ceph architecture with some of the components that can be deployed.
Storage types
Ceph provides object, block, and file based storage on commodity hardware.
Pool types
Pools constitute the basic building blocks of a Ceph cluster. They allow for high level organisation of data into logical storage areas, where each is defined by a number of properties (e.g. quantity of Placement Groups, CRUSH rules, resiliency factor). A pool can be one of two types:

RADOS Gateway multi-site replication
Charmed Ceph supports multi-site replication with the Ceph RADOS Gateway. This provides even more resilience to your object storage by replicating it to geographically separated Ceph clusters. This is of particular importance for active backup and disaster recovery scenarios where a site is compromised and access to data would be otherwise lost.
