I got a question about customer-managed database locations:
"We are preparing to install Ops Center with ECHA. The install docs say that ECHA uses a customer-managed database on a separate system. What if I partitioned a system, and had the EC node and DB node on separate partitions? Could that work?"
Theoretically yes, although I don't think we've tested that kind of setup.
The reason we say that the database should be on a separate system is because an Enterprise Controller failover doesn't include failover for the database. We assume that, with a customer-managed database, you'll have your own methods for protecting the DB from system failures. ECHA, then, just focuses on the Enterprise Controller, and assumes that the database will still be accessible when the new EC node comes up.
