Hitachi, Ltd. (TSE: 6501) today unveiled its 800-volt direct current (800 VDC) power and control architecture as fully integrated into the Vera Rubin DSX reference design, and compatible with the NVIDIA Omniverse DSX Blueprint to support future NVIDIA rack designs in gigawatt-scale AI factories.

The three-dimensional (3D) simulation model of Hitachi's solution, enabled by OpenUSD, replicates power behavior across the full electrical chain—from the utility grid to the data center rack—helping data center developers and utilities design, simulate, and deploy AI factories faster and with confidence. GTC 2026 attendees can experience the new grid-to-rack architecture demo in Hitachi's booth #344 March 16 to 19.
