These file systems have built-in checksumming and either mirroring or parity for extra redundancy on one or several block devices: Solid state media, such as flash memory, are similar to disks in their interfaces, but have different problems.
Typically a device such as a solid-state drive handles such operations internally and therefore a regular file system can be used.
Distributed fault-tolerant replication of data between nodes (between servers or servers/clients) for high availability and offline (disconnected) operation.
Distributed parallel file systems stripe data over multiple servers for high performance.
Some of the distributed parallel file systems use an object storage device (OSD) (in Lustre called OST) for chunks of data together with centralized metadata servers.
