The Best Security and Privacy
Data is divided into Slices at the Accesser and dispersed to multiple Slicestors in the Dispersed Storage Network. Each individual Slice contains too little information to be useful. Unlike solutions where whole files are stored, data remains secure even if transmissions are intercepted and decrypted, or if a storage node is stolen and decrypted.
Highly Reliable
A Cleversafe Dispersed Storage Network (dsNet) can tolerate multiple
failures of hardware, storage locations or administrators, while still
keeping data secure and easy to reassemble. Only a majority of Slices is needed to perfectly recreate the original data. Dispersed Storage is typically configured to have 99.9999999999% (12
nines) of availability, and may be configured up to 99.99999999999999% (16
nines) of availability.
Cost-Effective
Because Dispersed Storage eliminates the need to store multiple copies of data, the amount of overall storage expansion of data is only 30-100 percent more than original data. By contrast, copy-based storage methods typically make three to four copies, resulting in a 300 percent to 400 percent expansion, which increases cost and synchronization traffic.
Massively Scalable
The ability to configure a Cleversafe dsNet enables massive, scalable capacity. There are no centralized servers, and the majority of the processing is distributed to clients, which avoids processing bottlenecks.
Longevity
Cleversafe Dispersed Storage is designed to enable centuries-long storage. Integrity agents check to ensure Slices are still valid, and Rebuilding agents work to rebuild any corrupted or missing Slices. Rebuilding agents also enable hardware to be swapped out for newer hardware which essentially abstracts the data away from hardware.
Performance-Oriented
The IDA algorithms are computationally efficient, so they do not cause a bottleneck within your storage process. The dsNet Access software also is designed to optimize performance decisions for both reading and writing Slices. If a particular Slicestor is non-responsive or slow, the Access software can still recreate the original file based on having the threshold number of Slices.
