4 NEPHELE vision to develop an end-to-end solution addressing current limitations of intra- and inter-datacenter architectures 4

5 NEPHELE objectives 5

6 disaggregated rack disaggregated rack disaggregated rack NEPHELE architecture pod switch pod switch NEPHELE hybrid electrical-optical network pod switch pod switch optical packet switching at the pod facilitates rapid intra-pod connections for localized traffic, e.g. between disaggregated racks. hybrid ToR hybrid ToR hybrid ToR optical burst/circuit switching is applied for inter-pod traffic. Short-lived packet flows can be also handled by the electrical packet switched (EPS) network. smart NIC compute memory storage smart NIC compute memory storage smart NIC compute memory storage dynamically reconfigurable optical network datacenter resource pooling in disaggregated racks scaling in pods: datacenters in a box slotted optical network operation enables dynamic bandwidth allocation to the optical layer to upgrade network capacity, additional parallel planes can be added to the architecture in a pay-as-you-go fashion. 6

7 NEPHELE building blocks datacenter orchestrator northbound interface southbound interface SDN controller VM migration VM migration telecom network controller flexible optical transport network inter-datacenter VM migration over a flexible telecom network application-aware northbound interface SDN controller with southbound interfaces tailored electro-optic subsystems for dynamic network operation hybrid electronic-optical network architecture 7

8 SDN control plane integration current SDN datacenter applications orchestrator network controller optical network applications orchestrator network controller optical network virtualization of resources in the DC is crucial for costeffective performance scaling well proven for compute resources in the DC gaining ground for network, storage and memory resources inside the DC and in the cloud challenges persist, stemming from legacy architectures and associated control plane considerations current SDN datacenters rely on rigid optical hardware with extensive overprovisioning of bandwidth to address peaks in demand NEPHELE s optical network dynamically reallocates available resources: graceful scaling without overprovisioning NEPHELE s application-aware network controller reconfigures the network responding to the real requirements of the application on-demand 8

9 Creating market opportunities in Europe courtesy of Cisco Gartner, Inc NEPHELE will strengthen Europe s industrial position in the field of cloud datacenter technologies NEPHELE is developing an end-to-end solution extending from datacenter architecture and optical subsystem design to the overlaying control plane and application interfaces a vigorous multi-billion Euro market is addressed and leading players are involved near-market exploitation targeted: driven by user needs & aware of datacenter ecosystem 9
