It's great to see someone resurrecting and productising distributed memory, a concept that's been around for donkeys years.

@Matt B: DEC Memory Channel would be more akin to, say, RDMA over Infiniband, which if I read correctly, is just one piece of this stack.

At that price point, the use cases for this will remain slim and are basically identical with those of main-memory databases i.e. transactional systems with large working data sets. Although I can also see possible uses by the starry-joined OLAP crowd.

Ultimately this stuff just forms part of a hypervisor and permits what amounts to main-memory lending between VM hosts. The cloud computing people will love being able to have a memory rack next to their CPU rack.

And thus we reinvent the mainframe ...
