DynamicXcelerator AI Photonic Bundle

---

Data centers are fast approaching the power and performance inflection point, where the performance gains from electrical interconnects diminish and the power consumption required to transmit electrons through copper continues to escalate. We are now at the point where photonic interconnects can begin to be introduced to the data center. Over the next few years, the introduction of NxCPO chiplets will allow for the building of denser and lower-cost photonic fabrics for the data center. Fortunately for AI users, the initial system proofs are now available from Drut Technologies.

Drut’s disaggregated photonic fabric allows for AI solutions to be deployed to a broader group of users by providing a higher rate of resource utilization in a smaller infrastructure footprint, versus a lower rate of

utilization across a larger infrastructure footprint. Moving away from stacked interconnect hierarchies of electrical switches with a photonic fabric allows resources to be directly connected and grouped by nodes. This is how organizations will begin to deploy photonic platforms for AI clusters today. By decoupling resources from the server chassis with a fully disaggregated photonic fabric, users will add the ability to dynamically attach and detach resources to nodes as well as upgrade resources independently of CPU upgrades.

• Compose nodes by dynamically attaching and detaching resources without server reset or reboot
• Eliminate the power and data locality barriers
• Improve utilization of valuable resources such as GPUs
• Deploy modularity options for server and resource upgrades
• Lower Power – no electrical to optical conversions
