Content-Aware Segmentation

The Albireo architecture supports both fixed and variable block deduplication. Data can be intelligently segmented into chunks of variable length based on analysis of its content. Albireo uses content “scanners” to identify and optimize deduplication of objects within specific compound data formats (e.g. Microsoft® Office® documents, ZIP, PDF, tar). An API is available for vendors to implement their own application-specific scanners for further savings. Independent validation has demonstrated that Albireo offers 7:1 data reduction for general purpose environments, while data reduction rates of over 35:1 are seen for virtualization images generated by products such as VMware®.
