Chapter 1. Edge clusters
Edge clusters are a solution for cost-efficient object storage configurations.
Red Hat supports the following minimum configuration of an Red Hat Ceph Storage cluster:
- A three node cluster with two replicas for SSDs.
- A four-node cluster with three replicas for HDDs.
- A four-node cluster with EC pool with 2+2 configuration.
With smaller clusters, the utilization goes down because of the amount of usage and the loss of resiliency.
