Re: Redundancy
Please tell me how you convinced your boss that you needed a second identical vMax to mirror the first?
At a rough guess I'd say "if DC1 gets hit by a natural disaster we'd need one in DC2 so we can operate a full failover".
Your question seems a little like asking "why do we have two data centres, one of which spends quite a bit of time doing relatively little? Surely one is enough?"
