Community Forum > snapshots and encryption in Ceph based QS

1) How many snapshots can a volume have in the Ceph based scale out block storage?

2) Can you confirm that encryption is supported in the Ceph based block storage?

Hi Gopi,
As far as I can tell there is no hard limit to the number of Storage Volume (RBD) snapshots you can create. There is some resource usage for a snapshot so I expect that if there are too many there could be some performance issues but essentially I don't see a cap mentioned anywhere.

With regard to encryption support. Yes, QuantaStor supports encryption of both XFS and ZFS based storage pools. Ceph Pools are associated with OSDs each of which maps to a XFS based storage pool.

ps Apologies for the late reply, QuantaStor v4 shipped today so we've not been monitoring the forum as closely over the last few weeks.
