IMHO, you already have a decent box, I wouldn't think that CPU could be an issue. Is user+system > 80%? or is iowait > 80%? This is an important difference.
Depending on file caching, more memory is always a good upgrade. Then I would look at your I/O adapters, SCSI, SSA, etc. Adding more is good, proper placement is better. Adding more physical disks, can increase performance also. I second I/O drawer may be a good investment, if you need that many PCI slots. Run 'iostat 60', or 'vmstat 60' so we can see what is going on.

This server only handles TSM, no other task. But there is a lot of data-transfer from backup-pools to copy-pools and from disk-pool to tape-pool (150 GB disk-pool, data-transfer to copy-pool about 800 GB per day). I have some money left for increasing the performance : Does TSM support and use a second processor ? Thanks for help Chris
