I spoke to Brad Ascar and Dan Clarizio about this one and we have to change the process and at a minimum, communicate a warning that this requires more than one appliance to accomodate such a workload. Dan proposed possibly adding the list of regions with checkboxes that the user could select so they only manage what they care about.
I also think it might be worth to redesign the discovery process maybe make it a two step process with the warning messages that dave proposed reassigning this to the UI team
ok, UI doesnt want it :) @GregB what to do with this?
We're looking at ways to revamp the entire discovery process. I'm closing this BZ because I'm not positive this will every make it back to 5.6.
