What's the point of shipping more memory then? Maybe the OS can only address 4GB per process but is able to use up to 64GB in total (PAE)?
That was one argument from Cisco - that when the software catches up, they might be able to compartmentalize so that applications gain access to it individually. I didn't grill them too much on this, as we use IOS XR in the core mostly (CRS), and we don't need RAM too much since IPv4 is switched on MPLS labels, negating the need to hold a full IPv4 table on the routers. That said, I can see a use-case where the additional RAM on the CRS and ASR9000 can make sense if IOS XR is allowed to run separate VM's on the same control plane. I know that iso one of the ideas behind the NCS, but not sure whether it will be added to the CRS and ASR9000. Mark.
