Remember no matter how fast your network is you can only move data as fast
as your disk will read or write. I have a setup similiar to this and run
multiple sessions on our Oracle server but don't get gig throughput because
of how fast it can read from disk where the Oracle database lies. The max
backup I see is 30MB/s. When a gig card can do max 125MB/s.

Subject: Etherchannel and EBU backups.
hi Eric,
I am not sure whether it's feasible or not because I don't know how
etherchannel works. Is data going to go through four etherchannels
because you start four sessions? If so, your implementation might work.
Make sure not to start more sessions than your max mount point for your
node on the TSM server.
I hope you are aware that Oracle7 is not supported by both Oralce and
Tivoli anymore.
regards,
Thiha
