What is the best rule to use with performance tuning to get maximum speed from tape devices - should one use default buffer settings or custom buffer settings? Where do i find the recommendations for buffer settings for different drive types (HP LTO3 and HP LTO3 Worm in particular).

 

Other than buffer settings, what can be customized to provide maximum performance for drive speed? I am aware of multiplexing and datastreaming. Are there customized settings for SCSI HBA drivers and Tape devices drivers that will improce performance.

 

The OS is Solaris 9, NBU 6mp4 and SCSI HP LTO 3 tape devices.

 

Thanks.
