Hello,
I understand you're asking about the storage and maintenance of the Graph data. The OpenAIRE Graph is operated and maintained at the ICM Technology Centre of the University of Warsaw. Specifically, the Graph is hosted on the Okeanos SuperComputer, which has 26,016 cores and provides 1,082 Tflops/s of processing power.
For more detailed information about the OpenAIRE Graph Infrastructure, please visit our website: https://graph.openaire.eu/what-is-the-openaire-graph
I hope this information is helpful. Does it answer your question? If I misunderstood, can you clarify in English please?
Best regards,
Stefania
