Welcome back Robert. Lots of changes from the TSM 5 days. I don't have any links to docs, but my experience has been...
I'm running Windows, 32 GB RAM, TSM 6.3.4.300. I run 40 sessions on each Replication process. The process is replicating a group that may have several members, 2 up to 15 or 20; semi-random on how I assigned. I have a script that contains several REPLICATE NODE <groupname> commands. Each command runs one group, with WAIT=YES, then another, with an exception described next. I have a group that has nodes with a very large numbers of files for those nodes, thus the time required to determine what has to be migrated is long. The amount of data to replicate isn't huge, just the time required to inventory the status on a zillion files. Therefore, that group is first in the script, with WAIT=NO, to immediately start the next group in the script. Subsequent replicate groups all have WAIT=YES. The only performance issue that I've seen as an issue is monitoring bandwidth on the link between the source and target servers. I've watched Network stats in Windows Task Manager and depending on how many replication processes are running, the impact on the bandwidth goes up. I haven't seen any hits on CPU or RAM. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Robert Clark Sent: Thursday, December 17, 2015 4:39 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Node replication information? After a long hiatus from working with TSM, I am back to working with it again. (I left during the TSM 5 timeframe.) Does anyone have pointers to docs useful in figuring out how node replication determines how much to attempt to do in parallel, or general information on how to troubleshoot its performance.
