Deployment Guidelines

An important aspect of designing a storage cluster is to determine if the storage cluster will be in one data center site or span multiple data center sites. Use this information to learn more about considerations for setting up Ceph Object Gateway.

Multi-site storage clusters benefit from geographically distributed failover and disaster recovery, such as long-term power outages, earthquakes, hurricanes, floods or other disasters. Additionally, multi-site storage clusters can have an active-active configuration, which can direct client applications to the closest available storage cluster. This is a good storage strategy for content delivery networks. Consider placing data as close to the client as possible. This is important for throughput-intensive workloads, such as streaming 4k video.

Important: IBM recommends identifying realm, zone group and zone names BEFORE creating Ceph’s storage pools. Prepend some pool names with the zone name as a standard naming convention.
