(iwaniwan) About swift? In official documentation it is recomended not to use raid. The question is, if i have 4 servers with 16 disk on each, teoretically possible that one server drops and some file would be unaccessable? I have to use as distributed file server for big file from 100 Mb to 1 Tb

By default, each object is replicated three times in Swift. If you lose a disk, you still have two other copies. Replicas go to different deployer-defined zones, so that you even survive the loss of an entire server.

Cinder is used for block storage, not object storage. Totally different way of accessing storage.
