RAM gets extremely expensive when you try to get it in very dense capacity -- 32GB in 1U is completely doable, but it means shelling out for 8x 4GB DIMMs... And the neat thing is that 64GB per appliance is just the beginning... That's just in front of their 512GB of SSDs. I infer that they keep the "hottest" data in RAM, and use lightning-fast SSDs as a fallback. Nifty. (I bet they would also be amazing for very, very large varnish installs.)
