LizardFS – Software Defined Storage is a distributed, scalable, fault-tolerant and highly available file system. It allows users to combine disk space located on several servers into a single name space which is visible on Unix-like and Windows systems in the same way as other file systems. LizardFS makes files secure by keeping all the data in many replicas spread over all available servers. It can be used to build affordable storage, as it runs without any problems on commodity hardware.

Disk and server failures are handled transparently, without any downtime or loss of data. If storage requirements grow, it’s possible to scale an existing LizardFS installation just by adding new servers – at any time, without any downtime. The system will automatically move data across to the newly added servers, as it continuously takes care of balancing disk usage across all connected nodes. Removing a server is just as simple and easy as adding a new one.
