Don't know what hardware AWS is using, but Ark has server boards supporting 1.5TB, which is close enough to make 2TB believable: http://ark.intel.com/products/94187/Intel-Server-Board-S2600...

Edit: Supermicro has several 2TB boards, and even some 3TB ones: http://www.supermicro.com/products/motherboard/Xeon1333/#201...

This would require expensive 64GB DDR4 LR-DIMMs though.
