CRUSH is the powerful, highly configurable algorithm Red Hat Ceph Storage uses to determine how data is stored across the many servers in a cluster. A healthy Red Hat Ceph Storage deployment depends on a properly configured CRUSH map. In this session, we will review the Red Hat Ceph Storage architecture and explain the purpose of CRUSH. Using example CRUSH maps, we will show you what works and what does not, and explain why.
