Have you consider TSM on Linux on Intel?

I just assisted a university change from AIX with 3590 to Linux (cant
remember the IBM model of server) with 4560 (2 x 4560/LTO1 with 4 drives).

This Uni is probably smaller than you guys - but non the less they are
quite happy with the change...

Interesting! Right now we have installed 4 TSM Servers on 2 linux boxes
(XEON 2,8 GHz DP) and 8 x LTO II FC tape drives. While our main
production servers (10 x TSM 5.1) are still running on AIX 4.2 (2 x S7A
with  lots of 3590 drives), the new system is gaining ground and it
behaves itself very properly.
Next year we are going to replace all TSM Servers on AIX, libraries and
tape drives included.
We are considering very seriously to switch completely to linux. The
idea is to use roughly a dozen of machines for about two dozens of TSM
servers. The machines will share the storage resources (tape and disk)
in a storage area network.

One of the major problems we see with linux as tsm server platform is
that you forced to use a well-defined but very restricted range of linux
flavors which is supported by IBM. For example, we would like to use
Suse9 which is our standard system for all our linux serves but are
pinned to SLES 8 if we want to get support from IBM any longer.

Does anybody else consider Linux for large TSM environments or has
already experiences with it?
