In our office every machine runs OSX.
In search of an ideal storage and sharing solution we decided to let OSX Server handle all account information and auth requests whereas an 7TB QNAP provides NFS shares.
All shares are published as mounts in the companywide LDAP. As it turns out, handling permissions in this situation is very clumsy (e.g. inherit permissions on newly created files).
Unfortunately using NFS4 in combination with ACLs did not solve the problem. As a possible solution I set up a iSCSI connection between QNAP and the machine running OSX Server which in turn serves the LUN as AFP share.
Permission handling works like a charm for this setup. Although I am a bit concerned about the performance of this setup.
As we are a fast growing company we expect the solution to serve at least 100 clients while using files aprox. above 100MB each. Are there any known drawbacks of this solution?
