If you want a global file system look into AFS, it can do what you want I believe. Though I would not use AFS for anything like MySQL or Xen. AFS is extremely complicated but does provide a real generic distributed file system. Don't even bother going down the route where you cluster the memory together, latency will kill performance, and again you need very specialized apps to use it. And in any sort of disk/ram clustering performance will generally be shit until you have many nodes. Basically what I'm saying here is, based on your past posts you don't appear to be an extremely experienced admin/developer so what you are wanting to do will not work the way you hope it might. So don't waste any more time and drop the idea. nate
