Definitely not, and I can't see it ever happening with SCSI-based tape drives.
Your options really come down to: 1. Tune up the OS and NetBackup in great detail to make certain you have the very best you can get from the media servers. 2. Look closely at how the data is coming to the media servers - if they are coming from network backups, consider DSSUs to separate the slow network backup from destaging from local disk to tape. However, make sure you use fast disks and tune them up- I've seen reports on this list that suggest cheap SATA arrays cannot do this very well. There are quite a few ways to break down the process of the data getting from the client to the tape into separate sections that you can measure and tune up. If you are using UNIX servers Veritas have quite a bit of accumulated wisdom on tuning the OS - they just don't seem to publish it, and 1st line support don't know it either - but it is there. There are plenty on TCP/IP measuring tools and tuning advice for various kinds of NIC. You can run bpbkar with the -nocont option to see how quickly NBU is getting data off the disks.

A customer of mine is going to using STK T10000 drives and their media servers each can't supply enough data to keep the drive fully fed so we're hoping to be able to multiplex that way. Any other ideas besides making the media servers faster? Unfortunately that's not an option due to a software limitation. -- -Jason ----- Jason K.
