 Featuring pair of Xeon 8168 CPUs, 1.5 TB of memory, and 30 TB of NVMe storage,
 we get a system that consumes 10 kW, weighs 163.29 kg, but offers double precision perfomance in excess of 130TF.
 
-Further, the DGX-2 offers  a total of ~2 PFLOPs of half precision performance in a single system, when using the tensor cores.
+The DGX-2 is designed to be a powerful server in its own right.
+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.

 The new NVSwitches means that the PCIe lanes of the CPUs can be redirected elsewhere, most notably towards storage and networking connectivity.
 The topology of the DGX-2 means that all 16 GPUs are able to pool their memory into a unified memory space,
 though with the usual tradeoffs involved if going off-chip.
