Hi guys,

I wonder of how much number of snapshots kept at the same time affects performance on ceph cluster.

For ex. if I'll have:

a) 20TB HDD Storage(400 volumes)

b) 20TB SSD Storage(400 volumes)

and i'll do daily rbd snapshot of each volume and keep it for 5 days - coult it highly reduce overall ceph cluster performance? (volumes are based on images in RAW format).

Did any of you ever test it or have any source which explains it? I would be grateful for any information.
