I'd like to ask those who are using the LTO2 drives with TSM 5.3 a few
questions and some advice. I'm in the process of building a system to
replace the one I have. It will run AIX5.3 and TSM 5.3. My plan is to keep
the old system around and let the data expire off but lets talk about the
new system. Because I have little experience with 5.3 maybe those that are
using it can give me some advice.



Because these tapes hold so much data, using collocation as it is on TSM 5.2
seems a bit much, one tape per node. I have heard a little about the way
collocation has changed but for those using it on 5.3 would you relay your
experiences and recommendations.



Disk pools and tape drives will not be an issue but with almost 300 nodes
the system will be busy at times. Please relay your experience as to how you
run schedules. Do you have any nodes/schedules that run direct to tape?



Archives. Do you keep a second copy offsite or are they just sent offsite
and recalled if needed for reclamation or retrieval of data?



Anything you would do differently if you had the chance to redo your system?



Any other recommendations with TSM 5.3?



I have a windows server already running TSM 5.3 just so I can take a look at
it. No tape drives just a bit of disk to run a couple of desktop computers
to as a test. It is also running the admin console and my plan is to leave
it there and not install it on the TSM server.



Thanks for the advice and help,



Geoff Gill
