This reminds me how some companies still run old web apps on huge server farms made of boxes with 4GB of RAM. They're basically building in a limitation so the programmers can't try to gain performance boots via memory caching if they wanted to.

Also consider that though the article indicates a ~$900-1000 for a full 24GB system, it may be only ~$3000 for a S5520SC-based system with 96GB. I suppose one would be good for horizontally-scaled web caches and the other for big databases or whatever funky app might make tons of random seeks over a large dataset.
