B-Virtual is an innovator in the field of Cloud Storage System Technologies. 
Information Dispersal Algorithms (IDA's) have been used for years in telecommunications to enhance the reliability of transmissions to satellites and deep space missions like the Mars explorations. 

Further to this, the invention of a new class of online codes allows building much more efficient and hence faster codecs. 
B-Virtual has combined these technologies in an efficient and scalable cloud storage system. 
The B-Virtual Cloud Storage System offers unparalleled data availability; disks, servers, arrays, racks, even whole data centers can fail in the Cloud Storage System, without impact on the availability of the data to the end-user.
Cloud Storage System offers better storage efficiency. In traditional disk storage architectures RAID 5/6 technologies will be used within a data center requiring 15%-50% overhead disk space. 
Replication between data centers to achieve multi-site redundancy requires 100% additional disk space per site. 
The Cloud Storage System stores data across multiple disk systems and sites, without having to manage multiple data redundancy mechanisms.
The total amount of data that needs to be stored on disks across the data centers is only a fraction of what is stored in the traditional setup. 

Moreover, Cloud Storage System reduces the management cost of a geographically spread storage system. If the number of sites increases, the physical volume even decreases.
