There's these nosql things. I am not familiar with them at all. They seem nifty - some of you are way smarter than me, maybe you can correct me. It's like a giant bag with stuff in it, and there are keys tied to all of them hanging out the top of the bag. You just yank on the key and get your thing out. It's massively parallel and redundant, so maybe given enough leeway that bag can span continents, and we can each grab a key marked "file1.blah" and get it reasonably fast. It's got nothing to do with file systems. Am I right so far?
But so then, what I wanna figure out is, how can I set up a thing where I can basically have a file system be mounted locally on a few boxes, and have all that data get replicated on the other boxes as close to realtime as is reasonable... latency, resource sharing, all that. I'd basically like it so that me and my friends can each have the same data locally. We have tons of space, tons of bandwidth (it's local, after all), and we are willing to trade these to each have fully local copies. But what should we use? Lustre? Gluster? There seems like quite a few options. Lustre looks hard and Gluster looks expensive.
Chime in fellow slashdotters. You're all that make this place interesting anymore.
