Cleversafe Project Expands

Sharon Smith writes "LINUXWORLD, SAN FRANCISCO, August 15, 2006—The Cleversafe project, developers of the world’s first open source Dispersed Storage™ software, today announced it has launched a new open source project, called the DSGrid File System (dsgfs), to allow a dispersed storage grid to appear as a mountable file system for Linux-based software applications.

The new dsgfs project enables a dispersed storage grid, such as the Cleversafe Research Storage Grid -- a freely available, multi-terabyte globally dispersed storage grid, to appear as an ultra-reliable, durable hard drive to a Linux application. Using the dsgfs, users will be able to seamlessly store data on the Cleversafe Research Storage Grid, on a commercial grid or on a grid they build themselves. dsgfs initially will support various versions of Linux, including Debian, Fedora and CentOS.

“This new project means that most Linux-based applications will now be able to seamlessly take advantage of the benefits of dispersed storage, which include security, reliability and privacy,” said John Quigley, dsgfs project lead. “Cleversafe is inviting organizations and individuals to freely participate in the project.”

The Cleversafe Dispersed Storage technology uses Information Dispersal Algorithms (IDAs™) to separate data into 11 unrecognizable DataSlices™ and distribute them, via secure Internet connections, to 11 storage locations throughout the world. With dispersed storage, transmission and storage of data is inherently private and secure. No single entire copy of the data is in one location, and only 6 out of the 11 nodes need to be available in order to perfectly retrieve the data.

Data on the grid remains private and secure in the face of natural catastrophes, or failures of hardware, connection, facility, or IT management. Moreover, the individual data slices do not carry enough information for an unauthorized viewer to determine the original content.

The Cleversafe Research Storage Grid is freely available and is currently being used in testing and development environments.

The Cleversafe Dispersed Storage software, which allows developers to build their own dispersed storage grid, is freely available under the GPL open source license. Information on the DSGrid File System project is available at Developers interested in joining any Cleversafe Project, including dsgfs, can sign up at For more information, please go to"
