[ceph] How snapshots affect performance
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.
