Egonle,
 
I had a similar problem and was told by IBM support that TSM will not use the 
additional memory.  I was trying to use the /3GB switch with windows 2000 
server running the 5.3.0 TSM client.

Hi,

I am running a few huge file servers (~6-9 million files, 600GB-1.2TB data, 2GB 
MEM). In order to enhance backup speed I tried to set resourceutilization to a 
higher value (5-10).
After setting that value I monitored dsm process during backup. The process 
uses up to 2GB memory and exits with a memory error message.
TSM Client ran out of memory.
Now I'm thinking about installing up to 8GB (max. for W2K Adv. Server) 
additional memory for these clients. I'll set /PAE boot option in boot.ini in 
order to enable more than 4GB of memory.

Unfortunately I cannot figure out whether TSM client (5.2/5.3) is able to use 
that additional memory using Address Window Extension (AWE) API. Does anybody 
know whether it's supported?

How I can feed feature request to TSM development team?


Regards,

Egonle
