Your Tivoli Support Team should be able to answer this question at least in
AIX processor terms. This is what I think:
(1) AIX P660 4 processor with 2GB memory (equivalent) (2) if you
want to have good capacity.
What kind of database size do you have? That is a key missing sizing
element here. 1 P660 could handle the amount of data you have if you use a
Gigabit network with dual Gigabit adapters and a limit of 200 simultaneous
sessions. The key is the size of the database. Also, like on VM/MVS you
can run multiple copies of the TSM server on AIX and probably Solaris. Just
different ports for each one.
I have 1 P660 backing up a 8TB Windows server environment (clients), many
are 100mbit connected, 20 or so are gigabit. My P660 is as above, but it is
connected to a Shark so that makes the database fly. This all depends on
your database size and whether you want to run a multi-server configuration.
I am backing up about 300GB/night and the P660 isn't even doing anything
half the time.
The nice piece about SAN connected tape is it flies on copy pool copies of
large files and large file backups, but you have to have gigabit on the
network side to get the data there and your clients have to have high end
disk in them.
For the little amount of data you are backing up. I would buy 500GB of
high-end disk (T3s are not high-end disk), scale back on the number servers,
run everything to disk pools, and use the tape drives only for migrations,
restores, and copy pools.

Hi
We are moving TSM off of our IBM mainframe to a SUN Solaris environment and
would like feedback regarding the model/size of the SUN boxes other shops
are using to run TSM.
Our site:
We're currently running an IBM 9121 mainframe configured with two LPARs
running VM/ESA. We have about 4000 TSM users registered across 4 TSM servers
(~1000 users per TSM server). We receive about 50GB of data each day to each
server althought this can vary anywhere from 25 to 75 GB a day on any given
server. Maximum concurrent users at peak times can reach about 100 sessions
on each server. Our tape configuration consists of an IBM 3494 tape library
with 6 3590 E1A drives which we plan on SCSI or fiber attaching in the new
environment.
I would appreciate hearing from anyone running TSM on SUN servers with any
of the following information:
- what model/size box (other specs if available)
- how many users registered on each box
- maximum simultaneous users sessions
- how much data backed up daily
- tape configuration info
- attached to SAN?
- comments on performance
Thanks
