+spread over all available servers. It can be used also to build affordable
+storage because it runs without any problems on commodity hardware.  Disk and
+server failures are handled transparently and most of all 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.")
