Optimizing Primary Storage "One movie house is using [Ocarina’s new] feature in the production of an upcoming 3-D movie. It estimated that to keep all of the data online in the making of the film would consume 200 PBs of storage so it only was only going to keep 30 days worth of data online. The rest it had to move off to tape and then recall it if it needed the data. Using Ocarina and only saving the changed pixels, it can keep it all online and expects to see 200:1 reduction in data during production." [more...]

Optimizing Primary Storage "The Ocarina solution offers data movement as well. For example, you could have a rule [that] any file that has not been accessed in six months will be space optimized to its highest level and then moved off of your expensive NAS to a disk-based archive that uses SATA drives. Because of Ocarina's mixed-mode architecture, spanning across different storage manufacturers' platforms is simple." [more...]

Expert Insight: Data Reduction for Primary Storage "If moving 50 Tbytes of data from Fibre Channel disk to 50 Tbytes of SATA disk is interesting, then moving that 50 Tbytes from FC drives to 10 Tbytes of SATA storage ought to be irresistible. Startup Ocarina offers an example of this method"

Block-Level Data Deduplication Architectures.
"Ocarina uses a very different de-duplication technique to other suppliers, which involves 3D matrix representations of image and other content boundaries. According to Ocarina, this provides around a ten-fold reduction in the volume of home directories or mixed image and text data, and a three-fold reduction of image data only (including compressed images such as JPEGs). Although other de-dupe vendors talk of a typical reduction of 20:1 or more, that is for repetitive backup data. As a comparison, NetApp says that when working with home directories, its background de-dupe function typically reduces data volumes by around a third, far less than Ocarina's three-fold reduction."
