How to grill an EMC division chief
Just the other day we managed to get an email interview with EMC’s president of Data Protection and Availability, Guy Churchward, so El Reg's storage desk took the opportunity to ask him some of the questions about Data Domain that had been bugging us. El Reg: Why has EMC never provided global deduplication across Data Domain …

Well, HP storeonce is a scale out dedupe appliane. What dedupe across stores gives you is the ability to add and extend your existing stores without having to create new stores as you grow... you also get the supplementary benefit of increasing data set you can dedupe against. HP storeonce is already available as both a physical and virtual appliance.

You must be confused with Netapp C-mode definition of scale out. That isn't scale out. And btw, before you can claim scale out you need to figure out how to do scale up first - because you can't do that either.

Well, storeonce does dedupe across nodes. Catalyst stores can be created across nodes and these can scale across 4 nodes and across all the capacity in the node if you so desired. Instead of having to wheel in yet another data domain box, go through the grief of setting up more stores, HP federated catalyst allows you to extend your stores as you grow. HP Discover 2014.

Oh come come, HP scale up as well as EMC. If it were as simple as putting more boxes in the same rack EMC would have done that a long time ago. Although they did try something similar with the DD GDA box which didn't work out that well, so it was withdrawn.
Fact is HP can offer scale up, scale out and high availability configurations as well as a Software Defined:-) VSA version. Whilst EMC are still stuck with the same single controller scale up solution they acquired from Data Domain 5 years ago.
