I found that moving the DB volumes off JFS to raw logical improved our
performance tremendously - our full DB backups took less than half the previous
time to complete.  It was a small system though, one L32  cabinet and a single
frame LTO SCSI attached.

Unfortuneately, I haven't had the opportunity to be in an environment to compare
different server hardware on the TSM server performance...
Is the NSM the only IBM box you have?

Dale,

Thanks for the info. Its good to know we are not alone!

We too have serious performance issues with the NSM'S and are also
frustrated by their lack of scalability.
We also have Sun TSM Servers using raw logical volumes that fly along
by comparison, we will go forward with TSM on Solaris as the platform of
choice.

Thanks for your response
