Subject: [ADSM-L] Gig utilization during backups

I'd like to get some input on what others see on their port utilization
during heavy network traffic. With 350+ systems backing up to a single TSM
server I'm curious as to why we see only about 50% utilization on the GIG
port with max scheduled sessions set to 95. Sessions run extremely long
compared to when they were on the old system.



What have others seen their systems and what do you have set for max
scheduled sessions?



I still feel like this system, which has 4 CPU's is not nearly as fast at
moving data than my 2 CPU system was and the setup is very similar.



AIX 5.3 - TSM 5.3.3.0 - 4 CPU's - 4GB memory - Gig interface





Thanks,
