CHICAGO, Oct. 16 /PRNewswire/ -- Cleversafe, Inc., open source sponsor
and lead developer of software to create the world's first Dispersed
Storage(TM) Network (dsNet), today announced it has released the next
generation of its Dispersed Storage software into open source on its
http://www.cleversafe.org site. Enabling the first completely functioning
version of Cleversafe's dsNet, this release increases flexibility, ease of
use, integration and access, leading to a more private, secure, reliable
and cost effective method for storing and archiving large quantities of
data on a global scale.
Cleversafe's latest Dispersed Storage software incorporates an iSCSI
device interface, which allows any dsNet to appear as a network device on
the desktop, enabling users to transparently store and retrieve files as if
they were using a local hard drive. iSCSI is a network storage protocol
that is compatible with all major operating systems, including Windows,
Macintosh, Linux and Solaris. The Dispersed Storage software release
initially works on a Linux operating system, with other operating system
configurations to be released to the open source community later this year.
Because of its standard iSCSI interface, Cleversafe's Dispersed Storage
software now easily integrates with many other existing backup and
"We are excited to release this new version of our software into open
source and invite all interested developers to participate in the Dispersed
Storage community. We hope the open source community embraces this exiting
new paradigm for storing data by getting involved with testing software
stability and scalability, as well as by identifying initial target
applications and uses for Dispersed Storage," said Jonathan Zakin, CEO of
Cleversafe. "We are developing a fundamentally better way to store the
world's data on a global scale, and believe open source is the optimal
development model for achieving this goal."
Current storage backup and archiving approaches rely on multiple
copies, replication and synchronization technologies, which compromise
security, add complexity and increase costs. Cleversafe's Dispersed Storage
software divides data into "slices" using functions called Information
Dispersal Algorithms (IDAs) and disperses these slices, via secure Internet
connections, to multiple nodes on a dsNet. Each individual slice contains
too little information to be useful, but any threshold of the slices can be
used to perfectly recreate the original data.
Cleversafe Dispersed Storage software is based on traditional Cauchy
Reed-Solomon Information Dispersal Algorithms (IDAs) to provide more
flexibility in determining the width, threshold and reliability of any
particular dsNet. Developers will now be able to customize the number of
nodes in their infrastructure, adjust the threshold number of slices
required to reassemble data and fine-tune the reliability of their dsNets.
For example, dsNet developers can now configure their systems to use eight,
16, 32, or even 64 nodes, and can set an appropriate threshold number,
depending on their specific needs.
"This release gives the open source community the tools to develop
Dispersed Storage Networks with heretofore unheard of flexibility,
scalability and reliability, and we look forward to interaction with the
developer community to further this exciting technology," said Chris
Gladwin, chairman and CTO of Cleversafe.
Dispersed Storage promises to be a more secure, private, reliable and
cost effective solution than traditional copy-based storage methods.
Dispersed Storage Networks can tolerate multiple failures of hardware,
storage locations or administrators, while still keeping data secure and
easy to reassemble. Because Dispersed Storage does not make copies of data,
it reduces the amount of overall storage and bandwidth expansion of data to
10 percent to 50 percent more than original data. By contrast, copy-based
storage methods have a 300 percent to 400 percent expansion factor, which
increases cost and synchronization traffic.
Cleversafe's new upgraded open source Dispersed Storage software is now
generally available for free download from http://www.cleversafe.org.
Cleversafe, Inc. is the developer of Cleversafe Dispersed Storage
software, which uses Information Dispersal Algorithms (IDAs) to separate
data into unrecognizable DataSlices(TM) and distribute them, via secure
Internet connections, to multiple storage locations on a dispersed storage
network. 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 some of the slices need to be available in order to
perfectly retrieve the data. Data on the network 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. For more information, please go to
