What is Proxmox Ceph?

Proxmox Ceph is the Ceph distributed storage system built directly into the Proxmox VE interface. Administrators can deploy and manage a highly available storage cluster on the same nodes that run their virtual machines. Proxmox Ceph pools the local hard drives or SSDs from multiple Proxmox servers into shared storage that keeps working when hardware fails.

MrPlanB.com rates Proxmox Ceph highly for homelabs and small businesses because it removes the need for expensive external SAN or NAS hardware. The Proxmox GUI has simple tools for installing Ceph, creating OSDs (Object Storage Daemons), and checking the cluster's health. Running compute and storage on the same nodes makes the infrastructure easier to manage and cheaper, and gives Proxmox users enterprise-grade features like live migration and instant snapshots.
