Hi @Kinney, Paul Thank you for posting your question on Microsoft Q&A and for using Azure services.
If I understand correctly, you are trying to run Azure Redis Cache on a single F300 node cluster.
"It seems to require a minimum of 3 nodes."
You are right! The smallest possible configuration for the Enterprise Flash tier is 3 nodes.
Let me know if that answer your question.
Please do not forget to mark as accept answer if that answer your Question.
Regards,
Oury
