OneFS is a file system used by Dell in their EMC Isilon products. It is a top end storage system that controls the File System, Volume Management and Data security for large scale storage systems.
We are able to recover data from all EMC Isilon systems. OneFS is a combination of a File System, a Volume Manager and Data Protection into a single data storage package.
Data protection EMC Isilon Data protection uses Reed-Solomon algorithm for N+M protection with Forward Error Correction. When a file is written it is spread across several nodes using parity calculated at the level set for the cluster.
