I had the same problem about a year ago. I just switched my network
over to gigabit. Depending on how many machines you have, it may just
be easier to replace all their cards with gigabit cards and a gigabit
switch.<br>
<br>
If you don't have control over the network, you could just create an internal network with a gigabit switch.<br>

<br>I have a number of systems wired locally with switches and hubs. I would<br>like to be able to do more backups from these systems to a stand alone<br>backup system with a couple of large hard drives. The issue then becomes
<br>data transfer speeds because a couple of these systems have 100-200 GB of<br>data stored on them.<br><br>The typical data transfer speeds have been on the order of 2-3 MB/sec when<br>all network cards are 10/100 MB NICs.
<br><br>There are a number of online resources listed below on how to "tune" one's<br>machines to get faster data transfers. Has anyone out there "tuned" their<br>LAN in order to get decent data transfer speeds? Do these suggested changes
<br>truly move the transfer speeds up drastically? I realize there will be<br>collisions, etc. ... but I would guess that I SHOULD be able to get transfer<br>rates up to 25-50 MB/sec. Does that seem reasonable?<br><br>Or ... would I get better data transfer rates by mounting the drives with
<br>NFS on a Linux box and copying everything via NFS over TCP?<br><br>Any of your experiences would be greatly appreciated. Many thanks in<br>advance.<br><br><a href="http://rdweb.cns.vt.edu/public/notes/win2k-tcpip.htm">
