= Build Lustre Storage Cluster for 3D Fly platform =

== 0.Introduction ==
Some domain-applications usually need to computing huge data. It usually meet a bottleneck problem of performance. It will lead I/O performance to drag total performance. Thereforce, we use Lustre high performance stroage to improve I/O performance.
You can refer to Lustre web site http://wiki.lustre.org/index.php?title=Main_Page
== 1.Machine information & Software ==
 * Hardware
||Node ||8 nodes (1 server , 7 client provide disks)||
