Dear List,

We are in the process of upgrading our existing NetWorker setup here. 
We'll
be replacing our ADIC Scalar 1000 (8 x AIT3 drives) with an ADIC Scalar 
i2000
with about 10 LTO3 drives.  A good bit of the data is on multiple older 
machines
which will continue to backup over the network to a dedicated storage node 
and
then onto tape.  We are currently running Solaris 9 on our servers and 
storage nodes,
but I have concerns over what hardware to choose going forward.  Sun's 
midrange
servers (like the v440 / v490) seem to be a bit slow on the I/O in 
comparison to 
offerings from other vendors - such as IBM running AIX.  We will connect 
the storage
node to the network with either 2 GB ethernets, or a single 10G ethernet - 
figuring 
that a fully streaming LTO3 will pretty much use up a singe 1GB ethernet.

Any thoughts, recommendations, experiences, warnings would be appreciated.

Thanks
