Open Source Storage Management
Openfiler is a powerful, intuitive browser-based network storage software distribution. Openfiler delivers file-based Network Attached Storage and block-based Storage Area Networking in a single framework.
Openfiler uses the rPath Linux metadistribution. It is distributed as a stand-alone Linux distribution. The entire software stack interfaces with third-party software that is all open source.
File-based networking protocols supported by Openfiler include: NFS, SMB/CIFS, HTTP/WebDAV and FTP. Network directories supported by Openfiler include NIS, LDAP (with support for SMB/CIFS encrypted passwords), Active Directory (in native and mixed modes) and Hesiod. Authentication protocols include Kerberos 5.
Openfiler includes support for volume-based partitioning, iSCSI (target and initiator), scheduled snapshots, resource quota, and a single unified interface for share management which makes allocating shares for various network file-system protocols a breeze.
The following are just some of the features currently available (unless indicated otherwise) in Openfiler.

There may be hooks in the interface in the future to open and proprietary software; however these in no way affect the licensing of the core application as that is still under the GPL license.
