Thank you very much for your answer!
So I could save the use of hardware RAID controllers on storage servers. Good news.
I see in the Ceph documentation that I will have to manually configure the datastore to be efficient, reliable and full fault tolerant.
Is there a particular way to configure it, or just a datastore on every hard drive (12 datastores) and then Ceph will automatically use them to be reliable and full fault tolerant?
Can you advise me how to configure it in the better way?

Hi,
I would not use RAID5 since it would be redundant with what Ceph provides.
My 2cts ;-)
