DDN A3I SOLUTIONS – NVIDIA SUPERPOD REFERENCE ARCHITECTURE
► AI400 + DGX-2 SuperPOD at-scale testing and
validation published by NVIDIA:
• The AI400 All-flash appliance delivers incredible
sequential and random read performance, as
required by the heaviest DL workloads.
• Metadata performance scales well from 1 to 96
nodes, with no degradation as the number of
nodes and threads increases.
• The AI400 is a fully-integrated platform that’s easy
to deploy. DDN provides excellent technical
deployment and support services.
