Can you host multiple HANA databases?
With MDC, there can be only one HANA appliance hosting multiple HANA tenant databasese (hence multiple SAP systems) OR multiple HANA appliances that can host multiple HANA databases spanned across each other. You can also configure one HANA appliance in standby mode, so in case any of the remaining HANA hosts shuts down for any reason, the standby will take over its role automatically, which is called Host Auto Failover. So basically when you configure MDC, there is one system database per host and there can be one or multiple tenant databases located in that host. Because there is also a physical server partitioning, I can't say HANA host exactly means 1 HANA database, but if you ignore server partitioning configure you can think one HANA appliance as a HANA database.
