Keith,
I can't speak about 10Gb, but we use fibre-extended 1Gb ethernets between
our A & B data centers.  TSM clients @ A backup over the 1Gb network to
a TSM service @ B.  Their backups are stored on disks and tapes @ B.
Similarly TSM clients @ B backup to a TSM service @ A.  Works well for us.

Well,
On the IBM SP we ran backups over the internal switch which was
17GB(yte) if I recall.

And we currently have fibre attachements to drives, so I don't know why
the speed of
the NIC should be a concern. The operation of the NIC is under the OS,
not TSM.

Is anyone running TSM over 10 Gbit ethernet?  Is there any question
that it would be supported?

We have two data centers about 60 miles apart. We are planning to
send backup files from each data center to a 3584 ATL in the other
via a 10 Gbit ethernet link. The server hardware would be HP DL585-
G2's with Myricom 10 Gbit NICs and 2.6 Ghz AMD processors. The
operating system would be Redhat EL 4.

If anyone else has experience with TSM and 10 Gbit ethernet we would
be glad to hear about it.

Thank you,
