We have 4 Storage Groups per Node, and 3 nodes.  However, 1 node is
about 600 GB, the other two add up to about 600 GB.  They all backup at
the same time of the night, when they do a full backup on each box.  We
have other Exchange nodes that backup at various times but these three
(being the largest) I have backing up at a time when they can have more
bandwidth.  We back them up via the LAN (1 GB NICS each) directly to
disk.  They all take about 4 (sometimes 5) hours each to backup unless
the LAN is congested which means the total backup time for the 1.2 TB is
around 4 to 4.5 hours, which is about 4.5 - 5 GB per Min.  Which means
we're pushing the TSM Server's NIC to about the edge. :-D

The TSM server has 1, 1GB NIC (Teamed in Failover mode).  Note: The 1
Largest node only takes 4 hours to do a full backup.  We used to have
them in a direct to SAN backup, but discovered that doesn't work much
faster than doing the LAN backup, and has the added burden of tying up 1
or more Tape drives per node, which could be doing other things.  Now,
if I had a 1.2 TB single system, this would be a no brainer for Direct
over SAN backup. But until it gets bigger than 8-9 hundred GB it really
does work out to be equal either way.
