Very good overview Ray. Federated Storage and Virtual Storage Pools are coming whether we like it or not. Data at a Distance? Latency at a Distance (LaaD) is more like it, this will quickly become the biggest challenge (opportunity?) for storage vendors as they promote Federated Pools around the globe. It will be interesting to watch this technology evolve. Thanks, DrDedupe

Thanks for the comment. EMC didn't say when they were coming out with something. Also VMware at last years VMworld demo-ed a Vmotion at a distance using some special sauce from Cisco (which I think extended the LAN/VLAN). It was interesting but not yet ready for prime time.

If EMC is right, and Cisco can deal with a LAN extending across data centers, then VMware and others might just be able to support Vmotion over distances. And this is not just a DR solution but it's really a load ballancing solution as well.
