NIC Teaming
I am sure that this has been asked before, but I cannot find a good solid answer. I have an HP DL380g5 performance server that has two gigabit nics. We have a very network intensive ERP application that is running on it & I am starting to see that there is some performance bottleneck because of the network. We are running on an HP 5412zl switch with ALL clients at gigabit connections. Right now I am only utilizing one of the two NICs on the server, so I am wondering if there is any way to increase network performance by plugging in the second NIC & teaming. Won't my switch just turn off the second port because of Spanning Tree? Has anyone done this to increase bandwidth? If that isn't an option, what are the next options for increasing network performance?
Thanks for your help!

You can setup LACP on the switch for the two ports (link aggregation protocol). When you team the NICS on the HP DL380 G5 you can them up as failover or load balancing. From memory if you setup the load balancing and LACP you can use both port with aggregate bandwidth.

Any documentation on how to do that on the switch & then how to properly team the NICs?

If you plan for load balancing configuration, you can simply plug your two NIC on the same switch, same network and configure teaming. Although there are two NICs, but you only use one IP address and one virtual MAC address. Load balancing is the only teaming configuration that adds more performance. Failover (fault tolerance) don't.

So I saw something in the HP network configuration that mentioned teaming...if I just enable it, then plug in the network cord, it will automatically increase the bandwidth by 30-40% you think?
Give it a try, I think so. But you should baseline your current network throughput before you start
If you load balancing configuration works, it should.
