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.
