Chapter 1. Edge clusters
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.
