DESY completed a migration of user home directories from AFS to CephFS to address performance limitations, aging infrastructure, and operational complexity. The project involved deploying a high-availability Ceph cluster with NVME-backed metadata pools, erasure-coded data pools and quota management - demonstrating CephFS as a scalable, production-grade replacement for legacy AFS deployments in scientific research environments.
