It's like RAID -- you need one more drive than you want to use to store data. The current LLNL RAIT library code supports 2, 3, and 5 drive stripes (1+1, 2+1, and 4+1 data+parity). It wouldn't be hard to expand that to larger stripe sizes if need be, but probably not all that interesting unless done as described below. > In any case, once you are talking about an LTO4 drive, it is currently > impossible or nearly so to drive it full speed (except possibly by some > high > end IBM mainframes), so why complicate things when Bacula still lacks a > lot > of nice features ... :-) True, although with multiple 10G Ethernets and RTSP you can get pretty close to making a LTO4 sweat a little....8-). FICON Express multi-pathing is a lovely thing. Something like this would be more profitably be implemented as a virtual volume storage manager independent of a tool like Bacula.
