With the addition of the AV64 node type, the current requirement is to have a AV36P “seed cluster.” Most spreadsheets out there calculate single cluster capacity (either forward or reverse fashion). So the idea here is to add the number of nodes you think you need, look at the totals, and make sure it meets the environment’s requirements. Let me know your thoughts!
