Advanced Digital Information Corporation (ADIC), a leader in intelligent storage for the open systems market, is to acquire fellow storage firm Rocksoft for £36m.
Rocksoft’s patented data de-duplication software finds and eliminates redundant data, changing the fundamental economics of disk-based data protection and data transmission by improving the utilisation of disk resources and data transport networks. With the acquisition, ADIC expects to help customers manage, move, retain and protect their data more effectively on different kinds of storage resources.
ADIC believes that data de-duplication is an emerging technology that will play a major role in a broad range of applications for protecting and retaining data, including back-up and recovery, long term archiving, continuous data protection, and secure retention for compliance. The company also believes that it offers significant advantages for applications that benefit from efficient data transmission, such as remote replication and wide area network optimisation.
Rocksoft delivers its patented technology using its Blocklets software de-duplication engine designed to be integrated into storage and data transmission products. ADIC plans to integrate the de-duplication software into its branded products and offer it to licensees.
ADIC regards Rocksoft’s data de-duplication technology as representing the most important technical advance over conventional compression techniques in 20 years. It points out that whilst conventional compression can eliminate modest amounts of redundant data from file-sized blocks, offering typical gains of 2:1, Rocksoft’s technology applies flexible, large-scale de-duplication techniques both within files and across large data sets, finding duplicated elements among many different files and storing them only a single time. The results can be compression gains of 20:1 or more.
Besides reducing the storage needed for a given data set, ADIC sees the technology as enabling efficient transport of data over networks because it eliminates the need to send repeated elements. For applications that require higher levels of security and compliance, the software engine offers additional data services, including data integrity checking and encryption.
