I agree. My only point was that you still have to factor this time into the argument that by continuing to put NewStore on top of a file system you'll get to a stable system much sooner than the longer development path of doing your own raw storage allocator. IMO, once you factor that into the equation the "on top of an FS" path doesn't look like such a clear winner.

A lot of customers will get fixes without having to qualify a full new release (i.e., fixes come out between major and minor releases are easy). If someone is deploying a critical server for storage, then it falls back on the storage software team to help guide them and encourage them to update when needed (and no promises of success, but people move if the win is big. If it is not, they can wait). ric ________________________________ PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
