With a planned upgrade to 3.5, and the knowledge that 3i is the future, how close can you get to that future - now? Not close enough it would seem, checkout the HCL for 3i and the list of supported systems is pretty slim - a handful of servers, pretty much one from each vendor. Clearly as things move on, 3i in the box will become the 'norm' - however, for companies seeking to make the best out of the kit they have and upgrade, the idea that 3i may be available sometime soon for a USB upgrade to their blades/servers is I think somewhat on the hopeful side.
