MogileFS is our open source distributed filesystem.
Some of the advantages are
- No Single point Failure
- Automatic file replication
- Better than RAID
- Shared-Nothing — MogileFS doesn’t depend on a pricey SAN with shared disks. Every machine maintains its own local disks.
- No RAID required — Local disks on MogileFS storage nodes can be in a RAID, or not. It’s cheaper not to, as RAID doesn’t buy you any safety that MogileFS doesn’t already provide.
