ok merci e_esprit.
En serveur iSCI, j'ai trouvé openfiler qui à l'air de répondre pas mal à mon besoin
http://www.openfiler.com/
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 sits atop of CentOS Linux (which is derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor). 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 What, Why, Who, Where and How of Openfiler
What?
Openfiler is a Storage Management Operating System. It is powered by the Linux 2.6 kernel and Open Source applications such as Apache, Samba, LVM2, ext3, Linux NFS and iSCSI Enterprise Target. Openfiler combines these ubiquitous technologies into a small, easy to manage solution fronted by a powerful web-based management interface. Openfiler allows you to build a Network Attached Storage (NAS) and/or Storage Area Network (SAN) appliance, using industry-standard hardware, in less than 10 minutes of installation time.
Why?
Because life as a systems administrator is difficult enough as it is. Openfiler allows you to ease some of the pain by bringing together almost all storage networking protocols (CIFS, NFS, HTTP/DAV, FTP, iSCSI) into a single framework. So if your current pressure points arise from grappling with the task of providing secure and resilient storage to users, groups and computing resources in a multi-platform heterogeneous environment, Openfiler is the tool for you.
Who?
If you are a systems administrator looking for a way to take control of your storage resources without having to pull off the modern equivalent of The Great Train Robbery in order to afford it, Openfiler is the answer to your prayers. Openfiler is a serious tool meant for professional systems administrators with a keen desire for the ability manage network storage in an efficient and cost-effective manner.
Where?
Openfiler is meant for systems administrators and other technically minded individuals. Please visit the Download section of the website to obtain Openfiler. Please note that Openfiler is a powerful but complex piece of software which requires knowledge and understanding of a number of operating system, networking and storage concepts.

Open source provides you the power to modify and deploy software if you want to do so
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.
