> Asif Iqbal I did look at doing this, with the intention of allowing simultaneous streams to multiple tape drives, but put the idea to one side. I thought of providing interleaved streams, but wasn't happy with the idea that the whole process would block when one of the pipes stalled. I also contemplated dividing the stream into several large chunks, but for them to run simultaneously that seemed to require several reads of the original dump stream. Besides the expense of this approach, I am not certain that repeated zfs send streams have exactly the same byte content. I think that probably the best approach would be the interleaved streams. That said, I am not sure how this would necessarily help with the situation you describe. Isn't the limiting factor going to be the network bandwidth between remote machines? Won't you end up with four streams running at quarter speed? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
