[Veritas-bu] MPX Explanation

Hi All

Is there any chance someone could clarify MPX for me.

If you have MPX set to 4 for example and there are 4 streams hitting the drive. All 4 streams are writing in parallel as the tape spins. And if 3 streams are writing at 15mb/sec and 1 stream is writing at 10mb/sec, would the slower of the streams be a bottle neck for the other 3. My lack of the tape technology is most probably to blame, I am thinking of each stream the way fragments work on a tape , finish 1 start the next , please tell me this is not the same on each stream.

My thinking is that

- - - - - - - - - - - - - -

S1 15mb

- - - - - - - - - - - - - - -

S2 15mb

- - - - - - - - - - - - - - -

S3 15mb

- - - - - - - - - - - - - -

S4 10mb

- - - - - - - - - - - -

S4 will hold up the others ?

Thanks

Dave
