Re: Isn't restore 101
Why aren't the different components not integrated?
Hysterical raisins, for a large part. Security comes into play too: systems that have outside connections in whatever form are not allowed to even communicate with the main clusters directly, let alone have processes running on those clusters. And there is stuff like data conversion systems supplied by third parties, hardware and software, therefore not integrated as as matter of fact.
Furthermore, you don't have your monitoring system integrated with whatever you're monitoring, do you? Or your storage management system integrated with the systems you're providing storage to?
