Hi Zoltan...

That's a stumper.   I'll throw out a guess for people to stab at.

Appears to me that the 3494 is not an option.

Your Windows TSM server will need to communicate with the 3494 via LAN
(TCPIP), just as your AIX box does.  Or with TSM  library sharing, it has to
communicate with the other AIX TSM server (the library master) via TCPIP.  I
don't see how that would work if the Windows TSM server is outside the
firewall?

I believe you could make it work by physically sharing the 3494, if you
added NIC cards to the AIX & Windows box and set up a "3494-net", where only
the AIX host and the Windows host and the 3494 were on that network segment,
but that would require more E1A drives dedicated to the Windows host, in
addition to the NICS ....(very costly).

Maybe I'm making this more complicated than it has to be, but I would look
into physical partitioning of the 3583, available on the later 3583 models.
That would give you a solution that doesn't require TCP/IP, avoiding the
firewall issues.

Also beware, make sure you will have sufficient cartridge capacity in the
3583 - the "(and growing)" in your post makes me think 72 slots might not be
enough for TWO systems of indeterminate size.  You may need to go to the
3584.

OK, somebody else shoot it down...

We are working on expanding our TSM systems with additional TSM servers,
libraries, etc.

Here is what we have right now and where we are heading....

(1) TSM on ZOS using IBM 3494 ATL
(2) TSM on AIX sharing the 3494 but using its own 3590E1A drives attached
to a SAN via FC

New system #3

TSM on AIX (primarily for IMAGE and mail systems/Notes/Domino backups)
with a 3583-L72 LTO2 library

New system #4

The need has arisen for a new TSM server, dedicated to backing up 17 (and
growing) systems/servers (sizes unknown......don't ask). The reason for a
new, separate TSM server is due to firewall issues/requirements. The TSM
server is going to be behind the firewall with NO outside access (I will
have to physically walk to and directly access the TSM server. No internet
access....no dual-heading......).

To make things simpler/cheaper, we are proposing #4 to be an x86 box with
WINDOWS 2003 server (thought about Linux but I think the issue was the
availability of an FC card for it). We want to access/share the 3590E1A
drives and/or the LTO2 library.

What are you thoughts on this ?

Anyone have this kind of configuration ?

Is this possible/workable ?

What will I need, software wise from TSM ?  Library Sharing (never done
one of these !).
