Awesome! Emilio thanks for sharing this really good post. IMHO the best way to replicate is thru HANA itself with Bandwidth Optimizers on both sides. also, you have to consider the rest of the applications like BO, or maybe, it’s a suite on HANA, it would be nice how this kind of architecture change. Thanks again for so awesome note.
This scenario will work for both HANA appliances with internal disk, and also for configurations with external storage. It’s based on functionality offered by SAP on HANA since SPS 05. In this setup each individual HANA node replicates to corresponding standby HANA node on the remote data center. What it does basically is send the logs to the standby node to be replayed. Can be configured to work synchronously, asynchronously or asynchronous in-memory.
