IBM Spectrum Scale with Protocols

Die Bereitstellung von SMB und NFS über dasselbe Dateisystem ist aufgrund der unterschiedlichen Locking Mechanismen der beiden Protokolle nicht supported [Quelle: Samba/CIFS exports of the same directory]. Genau diese Restriktion wird durch den Einsatz von IBM GPFS / Spectrum Scale beseitigt.
