Yes, wrong read. With these numbers and Windows knowledge, TSM on Windows
is just fine.
Sorry for misleading answer.

The estimates were 50-75GB daily (not 1 TB daily), 22 clients - a pretty
simple load for W2K.

Mark,

based on additional info I would rather recommend going with AIX. The
suggestion to go with the OS you have more in-house expertize (i.e. Win)
is still valid.
However moving 1 TB you approach the limits of Windows. Dig down the list
archives and you will find a lot of discussions, my personal opinion is
that Windows should be used for up to 0.5-1 TB/24h. Right now your
estimates are for 1 TB, they will not decrease in the future, and getting
better service (performance / reliability / flexibility) users tend to put
on some unexpected additional load.
And main reason is not the performance as many people argue, but
availability and flexibility. Doing devices maintenance on Windows without
reboots is like walking on thin ice. And TSM experience showed that
instead of benefits Windows PnP functionality generated additional
problems.

Bottom line: even with small or no AIX knowledge in house, do not take AIX
out of the equation. Later migration from one platform to another would be
hard, non-trivial and time-consuming task.
For your requirements newer pSeries 630 or some existing pSeries 660 with
2 processors ought to be a good answer.

Another point - SCSI vs. FC drives:
Even if you start with single TSM server and all clients doing backup over
LAN, consider FC-attached drives with or without SAN hub/switch despite
small investment increase. Performance figures of *same* drive are better
with FC-attachment. Later migration of bigger servers (Domino and MS SQL
are good candidates) to LAN-free would be quick and easy.

Thanks for all the good info so far.  Here are some more details on our
environment:

We will initially be backing up 22 nodes, all of which will be a mix of
Windows NT and 2000 file servers.  One will be SQLServer on W2K and one
will be Domino 6 on W2k.  We also want to look at backing up Macintosh
design systems as well as laptops/PCs for power users.  Overall, a total
of about 1T will be backed up with approximately 50-75GB written to tape
daily.  We'd like to keep about 4 to 5 file versions on disk as well. Some
of the nodes are local to the data center but many will be pulled accross
the WAN (frame relay, 512k).  Our local Tivoli rep ran the numbers and
told us it shouldn't be a problem.

We haven't purchased any hardware yet for TSM, as management wants to be
sure we pick the right combination.  I am leaning towards TSM server
running on Win2000 because of our current in-house expertise.

We are excited about the capabilities of TSM combined with an estimated
$100k savings over the next year in hardware replacement costs alone.

How large of an envirnment are you going to back up?
I have about 200 nodes (AIX, NT/2000 & Netware) backing up about 200Gig a
night & am using an IBM M80 with 4 3590 E1A's (soon to be 6 H1A's).......

Hello all.

We are in the process of ditching our current BackupExec/ArcServe setup in
favor of a central TSM environment.  We have decided to expand our
existing 3494 tape library (additional frame w/ 2 3590 drives, SCSI) but
haven't selected the hardware/operating system for the TSM server.  These
are our options:

Dell 2600/Win2000
pSeries/AIX
iSeries820/PASE

Any recommendations for one system over another for the TSM server?  The
Win2000 option would be the cheapest but would it cause headaches down the
road?

thanks,
