Re: Dual Homed Question

As you said, it sounds great in theory. In practice it almost always
fails. The basic reason is name resolution.

When a machine has something to send to another machine it needs to know
its address. If the machines has two addresses, which one does it use? If it
looks in DNS and gets a 192.168.1 IP address for the target, it will send
the traffic through its own 192.168.1 NIC.

Sorry, should have mentioned that. they were connected NIC to NIC with a
cat5e crossover. No other network devices to cause any issues. Thought it
was straight forward but apparently I missed something.

It sounds reasonable, but there are so many variables...

What is the physical connection between the two Gig cards? Are they
going via a Gig switch or hub? What other loading is there? Are they
showing as Gig connections in the network status?

Are subnets etc. configured correctly on the NICs? I.e. does "route
print" on each machine look like the traffic should be going through the
gigabit connections?

After that you can get into performance tuning the actual network
connections ( search for gigabit in

but in my experience other file transfer protocols such as scp or FTP or
HTTP are quicker than using Windows file sharing.

Hello All:

Have 2 servers that require alot of data transfer between the two.
Rather than dragging all that data across the network, I dual homed both
servers 1 - 10/100 and 1 - 10/1000. The configuration is below. The
thought was to map a drive using IP address of the GIG card and force
file transfers through that connection. In theory it sounds good but
noticed that with the GIG NICS enabled, file transfer was horrible. Was
the thinking behind this technically sound? If not why and what could be
done to make this scenario work.

Thanks

Server 1
10/100 ip - 192.168.1.2
10/1000 ip - 192.168.2.2

Server 2

10/100 ip - 192.168.1.3
10/1000 ip - 192.168.2.3

Mapped Drive Server 1 to Server 2 by IP of 10/1000 .

Any input appreciated.
