"253,500 customers with 750 on HANA with the majority using HANA on-premises"
Is that HANA OLTP or just HANA anywhere for anything? It seems like HANA anywhere for anything has to be higher than 750, but maybe not.... Practically no one uses HANA for OLTP, that is true. It doesn't really make sense for OLTP as you need to write to persistent state, which negates the value of having it in memory.
