"The RAC manager evicts nodes and fails about as often as the DB itself so kind of a waste of effort"
Worked just fine for me in multiple companies on both Windows and Linux. What did Oracle say?
"All RAC nodes write to the same storage"
The same storage that can be Synchronously replicated to other arrays across sites and with a failure over time in seconds if it goes down. So clustering basically. Like it says on the box... Or you can automate failover and recovery to completely separate storage with Data guard for failover time of a few minutes.
"The way to do it is to shard and cluster a DB across multiple zones/DCs"
Like say Oracle RAC or SQL Server and presumably many others already can do then. But only RAC is true active active on the same DB instance.
"Google just released a DB called Spanner"
If I cared about uptime, support and the product actually existing next week, the last thing I would consider is anything from Google.
