Switch Provides Unparalleled Exascale Data Center Solutions with Cadence and @NVIDIA
Master the AI heat wave. Discover how Switch uses the Cadence Reality Digital Twin Platform to handle 10x rack densification and power the future of NVIDIA H100 clusters.
The Engineering Challenge - AI-Driven Densification :
The surge in Artificial Intelligence applications has moved the "cloud space" into a new era of massive compute requirements. For Switch, an exascale data center leader, this shift manifests as a "10x densification" problem. In the past, dense air-cooled environments were sufficient for racks pushing 50 or 60 kW.
However, modern AI workloads, specifically those utilizing NVIDIA H100 gear, require a leap into hybrid cooling envelopes that combine air and liquid technologies. The core challenge is not just providing the power, but validating that the heat generated by these hyper-dense clusters can be successfully removed without compromising the physical footprint or the surrounding hardware.
Reality Digital Twin - Pre-modeling and Validation Logic :
To navigate this complexity, Switch relies on the Cadence Reality Digital Twin Platform. This software suite allows engineers to create a high-fidelity virtual replica of the data center environment.
Environmental Stewardship in the AI Era :
As power demands reach the gigawatt scale, the environmental impact of data centers becomes a primary concern. Switch distinguishes itself by running its entire fleet on 100% sustainable power. The use of Digital Twin technology directly supports this sustainability goal by optimizing cooling efficiency.
By simulating the most efficient path for heat removal, Switch reduces the "wasted" energy typically spent on over-cooling, ensuring that the environmental story remains as strong as the technical one.
