Greetings,

1) Is anyone sharing a single library with multiple TSM servers?  If so,
how well is it working? (I also need to split-up our TSM server into
multiple servers, the current size of the TSM DB is around 35GB.  If I
buy a large library, is this library sharing really going to work
reliably as advertised?)

Ans: We had used single library with 2 TSM servers and it's working
flawlessly.

2) The current library I'm looking as is a new Compaq ESL9595SL2 (600
slots,
(16) 160/320 drives).  How would that compare to say- a storagetek
L700E? (I know there are ALOT of variables here, just looking for very
general
info) What advantages/disadvantages are there to using ACSLS libraries?

Ans: If you are happy with ESL9198, I will recommend to go for
ESL9595SL2 instead looking for new vendor.

3)  Is anyone familiar with the "new backup set option" in TSM 5.1?  I
looking in the online documentation, but can't seem to find anything

Ans : Purpose of backup set is to simplify recovery process. I think
it's not going to reduce data volume unless you keep few copies.

Thank you,

We have just implemented TSM 5.1 recently (3 weeks ago) and we running
the normal daily backup plus a monthly backup on all systems that is
kept for 7 years.  What systems are you requiring a monthly done on and
I will let you know how we have configured it.

We are also sharing a library with 2 TSM servers - one is a production
server backing up our prod network and the other is the test server
backing up out test network.  The prod server is the library manager and
the test server puts all it's request thru the prod box.

I am current using a compaq ESL9198 library. (200 slots, (8)DLT40/80
drives)
Unfortunately the capacity for the library is about 10TB and we have
around
15TB of data in our primary storage pool now.   Needless to say, I am
endlessly importing and exporting media to make room for scratch media,
volumes for file restores etc.

On top of this, our management is now requiring me to retain monthly
full backups.  (I'm planning on using backup sets, but if someone has a
better solution, I'd love to hear it!)

I am currently planning on upgrading our tape library but have a few
questions:

1) Is anyone sharing a single library with multiple TSM servers?  If so,
how well is it working? (I also need to split-up our TSM server into
multiple servers, the current size of the TSM DB is around 35GB.  If I
buy a large library, is this library sharing really going to work
reliably as advertised?)

2) The current library I'm looking as is a new Compaq ESL9595SL2 (600
slots,
(16) 160/320 drives).  How would that compare to say- a storagetek
L700E? (I know there are ALOT of variables here, just looking for very
general
info) What advantages/disadvantages are there to using ACSLS libraries?

3)  Is anyone familiar with the "new backupset option" in TSM 5.1?  I
looking in the online documentation, but can't seem to find anything

Any info would be greatly appreciated!
