You are asking a hardware question. X86 will be different from RISC 6000
and I suspect OS/390 is really fast.
What hardware?
Are the HBAs sharing a bus?
Are the NICs sharing a bus?
What kind of bus are the cards in?
What CPU? How fast?
Is TSM running solo on the server?
Are you going to disk? Tape? Disk that thinks it's tape?
Do you use Auto on any NIC instead of hard setting both sides?
Any routers in-between node and server?   Are they overworked?

I have seen 380GB/hour (200+ clients), last night was 310GB/hour peak,
and I bet that is not close to a record.  Last night I had a client run
at 36.5MB/sec.

Hello,

First of all, I know almost nothing about Tivoli so bear with me :)
Now, do you have any idea what's the maximum throughput between a TSM
client
and server, during a backup? Let's assume that we have a GB
infrastructure
connecting them. I'm experiencing really low speeds (3-4MBps) and
unfortunately it's impossible to try some other kind of data transfer
(via
ftp for ex.) between the same peers.

Thanks!

Octavian
