NVIDIA Unveils DSX POD Container Solution and OpenShell Reference Architecture at GTC Berlin 2026

In its GTC Berlin 2026 keynote, NVIDIA unveiled the DSX POD reference design, which packs 7 Vera Rubin NVL72 racks into a shipping container, with an on-site installation period of about 14 days; partners are expected to begin global deliveries in early 2027. On the software side, it introduced the OpenShell reference architecture, using Vera Rubin for LLM inference, the Vera CPU to run agents and the OpenShell secure runtime, and the BlueField-4 DPU to handle hardware security enforcement. NVIDIA also announced supply chain expansion targets for the next three years, including a 2.5x increase in substrate capacity, a 4x increase in Amkor interposer wafers by the end of 2028, a doubling of KYEC testing capacity in 2027, and a 15x initial increase in co-packaged optics light engine capacity, followed by another doubling to 30x by the end of 2028.
