Configuring a cluster for stretch mode

As a storage administrator, you can configure stretch mode in Ceph to distribute your cluster across multiple data centers, ensuring high availability and fault tolerance.

The following is an example user case for using the stretch mode feature.

A global e-commerce company with multiple regional data centers can implement stretch mode to ensure their Ceph storage cluster remains highly available and resilient. In the event of a failure in one data center, stretch mode ensures that the cluster continues to operate by redistributing workloads to other active sites, minimizing downtime and preventing data loss, thereby maintaining continuous service for customers worldwide.
