What you might have heard is simultaneous destages from a single DSSU.
That's also in 5.1MP4 - by default, NetBackup will schedule 4
simultaneous jobs of 25GB each. Frankly, the defaults suck for people
upgrading from an earlier release - it's a good way to fill your DSSUs
and watch your jobs fail with error 84s, especially if you don't have a
lot of idle tape drives.
All of the streams from a single DSSU still go to the same volume pool.
