大家都知道Freenas(ㄧ種以freebsd為基礎的)免費NAS平台，而且支援中文化，但是卻很少人知道或是比較少使用OPENFILERㄧ種類似以fedora等為核心的平台

Openfiler is a network storage operating system, fronted by a web based management user interface. With the features we built into Openfiler, you can take advantage of file-based Network Attached Storage and block-based Storage Area Networking functionality in a single cohesive framework.
Any industry standard x86 or x86/64 server can be converted into a powerful multi-protocol network storage appliance, replete with an intuitive browser-based management interface, in as little as 15 minutes. File-based storage networking protocols such as CIFS and NFS ensure cross-platform compatibility in homogeneous networks - with client support for Windows, Linux, and Unix. Fibre channel and iSCSI target features provide excellent integration capabilities for virtualization environments such as Xen and VMware.

iSCSI target functionality is especially useful for enterprise applications such as Microsoft Exchange server integration, Oracle 10g RAC backend storage or video surveillance and disk-to-disk backup.
