# Thin Provisioning

**Thin Provisioning** is a method of allocating storage space on demand. Instead of reserving the full amount of disk space upfront when a virtual machine is created, the system only consumes physical storage as data is actually written.

This technique is employed by the [[universitatsrechenzentrum-urz]] within its [[ceph-cluster]] to increase storage efficiency across the virtualization infrastructure.
