Message definition (Working with volumes)
A volume provides storage which is not destroyed when a VM is terminated. On our clouds, volumes use [https://en.wikipedia.org/wiki/Ceph_(software) Ceph] storage with either a 3-fold replication factor or [https://en.wikipedia.org/wiki/Erasure_code erasure codes] to provide safety against hardware failure. On [[Cloud_resources|Arbutus]], the <i>Default</i> volume type uses erasure codes to provide data safety while reducing the extra storage costs of 3-fold replication while the <i>OS or Database</i> volume type still uses the 3-fold replication factor.

A volume provides storage which is not destroyed when a VM is terminated. On our clouds, volumes use Ceph storage with either a 3-fold replication factor or erasure codes to provide safety against hardware failure. On Arbutus, the Default volume type uses erasure codes to provide data safety while reducing the extra storage costs of 3-fold replication while the OS or Database volume type still uses the 3-fold replication factor.
