I'd argue that while 640k was short sighted, I think it is unlikely we will see machines with much more than a terabyte of RAM in the lifetime of IPv6.I would be very careful with such predictions. How about 2 TB of RAM ?: "...IBM can cram 1 TB of memory into a 4U chassis or 2 TB in an eight-socket box in two 4U chassis..." http://www.theregister.co.uk/2010/04/01/ibm_xeon_7500_servers/page2.html http://www.theregister.co.uk/2010/04/01/ibm_xeon_7500_servers/ I don't know who will use it or how much they will need to pay for it or even when they will be available, but they are talking about it (in this case at the last CEBIT in March). People are building some very big systems for example with lots and lots of virtual machines.
On dell.com you can buy a PowerEdge R910 with 1TB RAM for around $80k. Laurent
