Re: TSM level for deduplication

2014-12-09 Thread Dave Canan
I submitted this request to IBM TSM development,  and am posting it on their 
behalf:
TSM Data deduplication has been in the product since 6.1 (server side data 
deduplication) and 6.2 (client side data deduplication) and is therefore 
considered mature at the 7.1 version.  The data deduplication mechanism 
itself has remained largely unchanged since initial release but improvements 
have been focused on performance and increasing the size of files that could be 
deduplicated.  We recommend that customers be at either TSM 6.3.5 (or above) or 
TSM 7.1.1.100 (or above). The TSM 6.3.5 version contains the important 
performance improvements though this version did not add improvements in 
deduplicating large files.  TSM 7.1.1.100 contains not only the performance 
improvements but also ability to deduplicate larger files as well as 
replication performance improvements.  All 7.1 deduplication customers should 
be at 7.1.1.100 due to this problem:

 Would anyone from IBM care to comment on this thread?  is dedup a stable
 mature feature in 7.1.1?

  Hi Thomas,
 
  when you are calling 7.1.1- an utter distaster when it comes to dedup
  then
  what issues are you referring to?
 
  I have been using 7.1.1 in a production environment dedupping some 500 TB,
  approx 400 nodes, without any bigger issues for more than a year now.
 
  Surely, there are still lots of not-very-well-documented features in TSM
  7, and I am not at all impressed by IBM support, and especially not DB2
  support and their lack of willingness to recognize TSM DB2 as being a
  production environment, but when it comes to dedupping it has been smooth
  sailing for us up until now.

Re: TSM level for deduplication

2014-12-07 Thread Prather, Wanda
Hi Thomas,
I agree, don't even think about using dedup at 6.2.5.  Too many performance and 
data handling bugs.
We're deduping 4.5-5 TB a day (Windows TSM server) and even had issues at 6.3.4.

Have seen no issues at all so far at 6.3.5 (and it should be easy for you to 
get there from 6.2.5).

Hi Thomas,

when you are calling 7.1.1- an utter distaster when it comes to dedup then 
what issues are you referring to?

I have been using 7.1.1 in a production environment dedupping some 500 TB, 
approx 400 nodes, without any bigger issues for more than a year now.

Surely, there are still lots of not-very-well-documented features in TSM 7, 
and I am not at all impressed by IBM support, and especially not DB2 support 
and their lack of willingness to recognize TSM DB2 as being a production 
environment, but when it comes to dedupping it has been smooth sailing for us 
up until now.

Emne: [ADSM-L] TSM level for deduplication

My management is very eager to deploy TSM deduplication in our production
environment. We have been testing deduplication on a TSM 6.2.5.0 test server,
but the list of known bugs makes me very uncomfortable about using that
level for production deployment of deduplication. The same is true of later
Version 6 levels and TSM 7.1.0. TSM 7.1.1.000 was an utter disaster. Is there
any currently available level in which the deduplication code is really fit
for production use?

IBM has historically described patch levels as being less thoroughly tested
than maintenance levels. Because of that I have avoided patch levels unless they
were the only option for fixing crippling bugs in code we were already using.
Is that attitude still warranted? In particular, is that attitude warranted for
TSM 7.1.1.100?

Has IBM dropped any hints about the likely availability date for TSM 7.1.2.000?
