Hardware limitation in case of MDC

Hello Experts

Need to understand whether there are any limitations in terms of memory allocation per instance if we are planning for MDC approach. We are planning to implement CAR and Hybris on same HANA Host considering MDC as the deployment option. As per the sizing we need 1.6TB memory for CAR and 512 GB for Hybris. We are working on a 5 year TCO at a rate of 25% CAGR growth per year. Need to understand considering the sizing figures, whether we will end-up in any limitations.

Thanks in advance
