Off topic, I wonder if it's a subjective bias among hardware producers against large amounts of RAM. Cost-wise, I don't think there is a problem to have multi-tera servers or desktops with tens or hundreds of gigs. And yet, you can't buy them. Even though as a software model it makes a lot more sense to keep all the data in ram and only ship the changes to an external memory.
I'm a bit annoyed they don't offer prices up-front, but a very nice product. I wonder if you can use a violin device as primary memory or you can only mount it as a fs.
I think they are mostly used as external storage, sometimes backed by spindles as a very fast SAN.
If you need huge amounts of local RAM then I think you're in the realm of the IBM zSeries and other mainframe devices. Nice stuff indeed, when you have the spare change...
