Is it possible when a server with 2 NICs to choose from which one to copy data over the network to my pc?

Thanks.

Unless something has changed over the last 10 years, the answer is no. At least, that's what I remember.

Well, the answer, as it so often is in IT, is "it depends".

If you pull the data from another machine and both NICs have a valid route to that machine and Microsoft Client is bound to both NICs, the NIC binding order will decide. So if you are going to pull vast amounts of data and you have a 10G NIC and a 100M NIC, you should put the faster NIC first in the binding order.

If you push the data to your two-legged server, the machine doing the pushing will have to find the server somehow, ultimately by the IP address. If both legs are registered in DNS under the same name you are sort of stuck, of course, but if all else fails, you can short-circuit that on the pushing machine by a HOSTS file entry. Our you just use the IP for targeting the data transfer.

Make sense?

Evgenij, knocking off some serious brain dust & rust here.  But, would not an IPSEC rule handle this..?

Tim,

I think there's too little data to answer that. Let's see if Nikolas cares to elaborate on the exact scenario.

Good morning all. Basically we have a  nas storage server with 2 gigabit server adapters. Both of them the link speed is set to auto negotiation but one them runs at 100mbps speed only. I am using robocopy to transfer archive files through the network(seems when external disk is attached on the server it causes a hp service to fail so i do not attach it for the moment that is why i use robocopy through network). I noticed that sometimes the transfer may use  the nic with the link speed 1gbps but some other times when am transferring again it may use the nic with the link speed 100mbps. Both nas storage ip are registered to the dns. 


Note: I do not know about ipsec

Edit: Switches here support up to 1000mbps wondering why the nic runs up to 100 mbps only. Will need to check cable types also.

Also i am reading about the binding order since i didnt know about that.


Thank you [smile]

Make your life easier and use the IP in stead of the name

i have read about network binding actually i used this link : http://techrena.net/view-change-network-adapter-card-priority-binding-order-windows-7/ in order to understand it better. (Thanks very much CJ learned something new today)

Edited: Thank you all so much. Accessing the server through network using  ip of the nic card that is using (link speed 1000mbps) instead of the hostname does the trick.

Thanks Tim. Am sure we will learn it sooner or later. Some % at least [smile]


Note: Indeed my life got easier now

I just heard of a command -  forcebindip - that can be run in the command prompt.  Maybe it will help.

I haven't had to deal with physical servers in several years but back in my former life when we were working with dell servers and cisco networking gear, we would get some really awful results with autonegotiation.  Things always worked best when we set the cisco ports to only 1000 and the operating system NIC to do the same (usually a custom NIC driver utility would allow the setting).  Autonegotiate on both sides was disaster.

If you have a local DNS server you can put in a static record for the Fast NIC to save you remembering the IP address
