1. Background knowledge:
NAS is a network file system. The general NAS supports NFS, CIFS and FTP.

2. Application scenario:
Ceph needs to support NAS network file protocol in virtualized, containerized
and hybrid cloud scenarios.

3. NAS solution:
The NFS protocol exports CephFS to the NFS protocol through the NFS-Ganesha
open source component FSAL module; the CIFS protocol exports CephFS to CIFS
through the samba open source component VFS module; but FTP does not have
this way?

4. FTP solution:
huanwen chose proftpd open source component to do the service software, but
it does not have a similar adaptation layer to export CephFS to FTP protocol.
Therefore, we developed a set of adaptation layer to call libcephfs to implement
CephFS out FTP protocol(Implementation framework introduction). The modified
code address is : https://github.com/renhwztetecs/proftpd2

5. Best Practices:
a> performance test
b> Proftpd HA solution implementation
c> application examples
