Questions related to Container pools

[PAC Brion Arnaud]

Hi Team !

IBM recently released an interesting document summarizing best practices with 
regards to container storage pools 
(https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Tivoli 
Storage Manager/page/Container Pool Best Practices ) and some of the 
information in it triggered two questions, which I would like some Spectrum 
Protect insider (Del ?) or anyone having good knowledge of this to answer ...

First question :  page 14 of the PDF document, chapter 1.4 , states that it is 
not appropriate to use container pools in the case of NDMP backups. What is the 
reason for it ? My understanding is that it is possible to make use of NDMP 
without a tape based storage pool, thus I don't get the point here ...

Second question : several references in the book are seeming to stress that one 
should make use of ONE SINGLE container storage pool for a whole TSM server 
(chapter 1.2.5.1.2 page 13, chapter 1.5.1 page 15). I do understand that 
deduplication is made at storage pool level, and that segregating backup data 
in several storage pools will weaken deduplication rates, but are there some 
other reasons which are not explained in the book, that would justify the use 
of only ONE container pool (like more hammering on the TSM DB during backup 
times if we make use of several storage pools, or others I did not think about)
We plan to build a new TSM environment which will be based only on container 
storage pool(s ?), and I feel kind of uncomfortable to send all of my data in 
the same bucket (less granularity for reporting, auditing, protecting and so on 
...).  Does someone have arguments (pro or cons) or experience to share about 
this ?

Thanks in advance for your feedback !

Cheers.

Arnaud

[Stefan Folkerts]

Eric,

Yes, we are running server-side dedup and compression on the site mentioned
earlier, I can't say I see these spikes but the system is rather busy
during the day as well so it would be kind of difficult to spot I guess. :-)

Re: TSM 7.1.7 server CPU behavior

[Ryder, Michael S]

You didn't mention the OS.

Have you considered running any diagnostic tools to figure out exactly what
process is causing the extra spikes?  For example, top or collectl (unix),
or perfmon or resource monitor (windows)?

By the way, it's not a monitoring tool because the spikes disappear right after 
the backup window...

Hi Eric,

I only have sar data of last night but I see a load around 40% that breaks down 
to 15% user, 5% system 10-20% iowait and the rest being idle.
10% is very low, it must be overpowered or still running a very low load.

Maybe it's a monitoring tool that is hitting the system every 5 minutes, do you 
see entries in the activity log that match the load? do you seen more iop/s on 
the database?

Re: TSM 7.1.7 server CPU behavior

[Loon, Eric van (ITOPT3) - KLM]

Hi Stefan!
The load is rather low, it's sized for future growth. I'm just curious if you 
see those short peaks too or is the load overall the same?
Do you use server-side dedup by the way?
Thanks again for your help!

TSM 7.1.7 server CPU behavior

[Loon, Eric van (ITOPT3) - KLM]

Hi all!
We are running a 7.1.7 server with a directory container storagepool (dedup and 
compression enabled). When we have multiple clients (with client-dedup 
disabled) backing up to it, we notice a peculiar CPU usage. Overall CPU is 
about 10%, but we see short peaks to approx. 30% every 5 minutes. Since this 
server is the only one with container storage pools in our company I cannot 
compare this behavior to other TSM servers. Is this behavior seen on other 
servers too?
Thanks for any help in advance!
