Good choice

Bad, get 10Gbit, yes really

Where did you get it from that ansible is recommended? Ansible is a tool
to help you automate deployments, but I have the impression it is mostly
used as a 'I do not know how to install something' so lets use ansible
tool.

Don't waste a vm on this?

If you want to create a fancy solution, you can use something like mesos
that manages your nfs,smb,iscsi or rgw daemons, so if you bring down a
host, applications automatically move to a different host ;)

Subject: [ceph-users] Need advice with setup planning
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. I failed to use it on
lab, but it seems more recommended.
- Install Ceph Nautilus
- Each server will host OSD, MON, MGR and MDS.
- One VM for ceph-admin: This wil be used to run ceph-ansible and maybe
to host some ceph services later
- I'll have to serve samba, iscsi and probably NFS too. 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;
