Keynote: Real Talk: A Ceph Users Panel
summary
Six Ceph users describe concrete deployments: block, object and CephFS at cloud providers, universities and labs; one site runs 25 PB legacy + 45 PB new storage, another consolidates onto Rook and reports object as the largest workload. They cite value from the open-source community, list real failures (kernel bug causing MySQL crashes, RBD fsync-heavy workloads, MDS and Ganesha hiccups), praise smooth upgrades via Rook, and give practical advice: start small, run dev clusters and get hardware and capacity guidance up front.
