The emergence of data-intensive applications in medical and other fields of study has created the need for increased storage space. It is often the case that these data should not or cannot be placed in the same domain. The data usually requires considerable computational power to process, which has inspired the area of Grid computing. This study proposes a new methodology for sharing storage volumes across distributed domains securely and making them accessible to all members of a grid. The proposed system was designed with the intent to integrate with the Globus Toolkit, which gives it the advantage of having useful features that are commonly necessary for data intensive applications.
