There are many faces and thus functionalities of virtualization beyond the one most commonly discussed which is consolidation or aggregation. Other common forms of virtualization include emulation (which is part of enabling consolidation) which can be in the form of a virtual tape library for storage to bridge new disk technology to old software technology, processes, procedures and skill sets. Other forms of virtualization functionality for life beyond consolidation include abstraction for transparent movement of applications or operating systems on servers, or data on storage to support planned and un-planned maintenance, upgrades, BC/DR and other activities.

So the gist is that there are many forms of virtualization technologies and techniques for servers, storage and even I/O networks to address different issues including life beyond consolidation. However the next wave of consolidation could and should be that of reducing the number of logical images, or, the impact of the multiple operating systems and application images, along with their associated management costs.

This may be easier said than done, however, for those looking to cut costs even further than from what can be realized by reducing physical footprints (e.g. going from 10 to 1 or from 250 to 25 physical servers), there could be upside however it will come at a cost. The cost is like that of reducing data and storage footprint impacts with such as data management and archiving.

Savings can be realized by archiving and deleting data via data management however that is easier said than done given the cost in terms of people time and ability to decide what to archive, even for non-compliance data along with associated business rules and policies to be defined (for automation) along with hardware, software and services (managed services, consulting and/or cloud and SaaS).

Ok, nuff said.
