Hello Salsa,
I have tested Ceph using VMs but never got to put it to use and had a lot of trouble to get it to install.
if you want to get rid of all the troubles from installing to day2day operations, you could consider using https://croit.io/croit-virtual-demo
- Use 2 HDDs for SO using RAID 1 (I've left 3.5TB unallocated in case I can use it later for storage)- Install CentOS 7.7
Is ok, but won't be necessary if you choose croit as we boot from the network and don't install a operating system.
- Use 2 vLANs, one for ceph internal usage and another for external access. Since they've 4 network adapters, I'll try to bond them in pairs to speed up network (1Gb).
If there is no internal policy that forces you to do seperate networks, you can use a simple 1 vlan setup and bond 4*1GbE. Otherwise it's ok.
- I'll try to use ceph-ansible for installation. I failed to use it on lab, but it seems more recommended.- Install Ceph Nautilus
Ultra easy with croit, maybe look at our videos on youtube - https://www.youtube.com/playlist?list=PL1g9zo59diHDSJgkZcMRUq6xROzt_YKox
- Each server will host OSD, MON, MGR and MDS.
ok, but you should use ssd for metadata.
- One VM for ceph-admin: This wil be used to run ceph-ansible and maybe to host some ceph services later
perfect for croit ;)
- I'll have to serve samba, iscsi and probably NFS too. Not sure how or on which servers.
Just put it on the servers as well, with croit it is just a click away and everything is included in our interface.
If not using croit, you can still install it on the same systems and configure it by hand/script.

I have tested Ceph using VMs but never got to put it to use and had a lot of trouble to get it to install.Now I've been asked to do a production setup using 3 servers (Dell R740) with 12 4TB each.My plan is this:- Use 2 HDDs for SO using RAID 1 (I've left 3.5TB unallocated in case I can use it later for storage)- Install CentOS 7.7- Use 2 vLANs, one for ceph internal usage and another for external access. Since they've 4 network adapters, I'll try to bond them in pairs to speed up network (1Gb).- I'll try to use ceph-ansible for installation.

Not sure how or on which servers.Am I missing anything? Am I doing anything "wrong"?I searched for some actual guidance on setup but I couldn't find anything complete, like a good tutorial or reference based on possible use-cases.So, is there any suggestions you could share or links and references I should take a look?Thanks;_______________________________________________
