OpenFiler adalah sebuah 'storage management operating system' atau Sistem Operasi pengelola penyimpanan data. Disamping kernel, OpenFiler memanfaatkan paket-paket aplikasi Open Source lainnya seperti Apache, Samba, Linux Volume Management, ext3, Linux NFS dan iSCSI yang semuanya ditargetkan untuk pengguna enterprise.

Openfiler menggabungkan teknologi open source tersebut menjadi solusi yang kompak dengan frontend dan GUI berbasis web yang mudah diatur.
