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.

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.

Won't the STP Protocol on the switches "shutdown" one of the links if they
don't go into the same switch? Wouldn't it be seen as a rudundant path to
the same MAC over more than one switch?

Hello Phillip,

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.

Ok. Different switches,..different MACs,...it prevents the error, or at
least fools it into not complaining.

Sorry for my incompetence, but in this case could be used a port trunking?

I think that is for VLANs where there is more than one subnet on a single
physical path. Whole different situation. May also refer to a "router on a
stick" situation which could be a VLAN or a Multi-net,..still a whole
different situation.

Sorry, but there are different definitions for the "trunking". In case of
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.
