It's going to be so good to finally have an open source option for large storage building blocks. It's of particular interest to those of us in HPC as if you are building a large parallel file system and you don't want re-build times to suck your options are basically one of the following.

- IBM's GPFS

- Panasas' PanFS

- Xyratex's -> Seagate's -> Cray's -> HPE's GridRAID in Clusterstor/Sonexion prodcuts

Though ZFS and dRAID will likely show up in that last one in the future.
