teaming 2 network cards
Hello,
i have two HP DL 380 D servers in my network, runing windows 2003 server and SQL 2005. i like to improve the network performance teaming the network cards in each server. do i have to connect bth NICs to the Same Switch or i have to connect them to two different switches. i planned to conect them to two different switches and split the network connectios between them but i'm not sure. -- Best regards, Michael Hello Michael,
Single switches or did they work as a stack? With single switches, you will get errors in the event viewer. If they are connected in a stack, you can use different switches from the stack.

I have had it with 2 switches in different offices (same subnet), even with fault tolerance configuration, that my event viewer was running full with entries like "the switch is in more then one subnet, reconfigure the network connection". And since we have now running stack switches it is no problem anymore.

VLANs it gives you the possibility to send your traffic form a VLAN to another. But, there is, so called, "Link Aggregation" which is also is a port trunking. I've configured 2 Allied Telesyn switches with the link aggregation (port trunking) on a connection between them. The standard for this technology is IEEE 802.3ad. "Link Aggregation, also called trunking or port trunking, is a technique of combining physical network links into a single logical link for increased bandwidth, achieving load balancing and increase fault tolerance." Thank you for your reply Phillip, hope somebody will throw the light on this situation. Show quote
