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.

Hi all,
a question about increasing the performance of my TSM-Server:
TSM-Server : IBM H80 ( 2-way RS64III-450MHz-processor, 2GB memory ), AIX
4.3.3 , TSM 4.1.4
I see with the monitor-tool that my server has over a longer period a
cpu-utilization of more than 80%. 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
