Unfortunately, TSM Server is stiil running in test mode (I have started from
6.1.0 and reached 6.1.3.1). I am going to use de-duplication on TSM server and
was testing it in this mode.
We have pospounded TSM 6.1 implementation because, in my opinion, it is still
not stable enough for production environmrent. It is just a fact - IBM has
removed version 6.1.3.0 from market and approximately for one week 6.1.3.1 was
not available at all (no official version except bad 6.1.2.1!!!). I am waiting
for new version 6.2.0, which will be available soon, and I hope it will be
better than 6.1. By the way, IBM is going to use DB2 9.7 instead of older 9.5
in 6.1. Unfortuately it can mean anything from fixing all problems of 6.1 to
having additional problems in 6.2.
Now about CPUs and memory size. All previous versions of TSM Server up to 5.5.4
were not using a lot of CPU and memory resources. After implementing DB2
picture has been changed a lot. Processes like db2sync are consuming a lot of
CPU resources in addition to dsmserv and you need much more space for databse,
logs and archives. Unfortunately, TSM documentation does not give real
requirements for system resourses. My suggestions are:
1) you definately do not need to increase memory to 32-40 GB. I think 12GB,
recommended by IBM, is enough;
2) four Power5 570 1.9GHz cores will be ebough as well.
Take them as they are, because I have only information from our test
environment.
If you are planning to implement TSM 6.1.3.1 (not implemented yet), wait for
TSM 6.2 and good luck.
Regards,
Grigori

Subject: [ADSM-L] TSM V6.1.3.1 and memory requirements on series
Hi All,
I'm wondering if anyone is running TSM V6.1.3.1 on an IBM server similar to a
p5 p570? I definitely need more memory for V6, since I only have 8GB and the
documentation says the minimum memory for all but the tiniest server should be
12 GB, 16 GB if using deduplication. I'm considering installing about 32 - 40
GB total memory.
We back up about 5 TB per night and have 207 client nodes, one server instance.
I'd like to know about any real-world experiences with similar configurations
and how much memory your server(s) have and is it adequate? Also, our p5 p570
has two two-way 1.9 GHz processor cards. Do you have an opinion on whether I
should add to or upgrade controller cards while I'm at it?
Thanks!
