I'm not an expert in replication solutions provided by storage vendors
but I did hear some compliments about old good EVA. Even though, I
believe this induces some additional dependencies between two storage
boxes. On the other hand, storage vendor replication can keep DR site
more up to date and up to real time.
Cost could be another advantage of manual standby assuming scripting
is done properly and management efforts are not high.
