[Deepsea-users] Deploying on 3 networks with DeepSea

Hi list,
does the following scenario ring any alarm bells with anyone?
The cluster has a salt-master, MONs and OSDs. All nodes have 3 networks: a 
management network and public- and cluster-network. All nodes have a hostname 
that resolves via DNS to the ip on the management network. The ips on cluster- 
and public-network don't correspond to DNS names.
The MONs derive their IDs from the short hostname, which would resolve to the ip 
addresses on the management network if one would attempt that.
The cluster deployed and operates fine. Is there any conceivable disadvantage 
with this setup? For example:
Should there be dns names for the public-network ip addresses?
Does DeepSea have any issue (or will have issues in the future) with running on 
the management network (the salt master has access to the public-network)?

Imho this setup should work fine, but I might be missing something.
