+On the storage side, the DGX-2 comes with 30TB of NVMe-based solid state storage.
 For clustering or further inter-system communications, it also offers InfiniBand and 100GigE connectivity, up to eight of them.
 
 Further, the [DGX-2][b] offers  a total of ~2 PFLOPs of half precision performance in a single system, when using the tensor cores.
