Understand what 'Non-disruptive' Means
When vendors talk about non-disruptive migration you need to squint between the lines and ask the right questions to determine if they mean truly non-disruptive or sometimes non-disruptive.
Wikibon recently defined federated storage as a collection of autonomous storage resources governed by a common management system. The best way of thinking about federated storage is as a collection of storage resource nodes which are loosely connected. The nodes can be storage arrays or appliances controlling multiple arrays. The management system provides rules, in particular about how data is migrated throughout the network.
