Networking is not my strong suit. I'll explain how that client communicates
with
the ADSM server.
We've got a dedicated backup network and most of our machines have 2 nic cards.
The 2nd nic card is dedicated to the backup network. That 2nd nic is a 100mb
ethernet set at full duplex. A standard ethernet cable connects that card to a
3com 3900 switch. That switch (by the server farm) communicates with another
3900
switch (next to the ADSM server) over fiber. The ADSM server (RS/6000 S70) has
a
gb card and connects to the 3900 switch by a fiber cable.
I should add that this is the only client that gets this type of throughput -
even
though most have the same configuration. The files on that server are VERY
large. That node transfered 38.5 gb's, but only 54 files were backed up.
