In order to get maximum throughput on a sever with 4 nics i would like to team them. Are port channels and etherchannels the same thing? Most of the reading seems to be switch to switch. What needs to be done if i am going from a sever to switch. Great the port channel then add the interfaces to the port channel? Any tips or ideas? Thank yo in advance.

Also do the interfaces in the port channel have to be trunks or is that just switch to switch?

this will depend on the server and the switch.

Most servers come with basic software for NIC teaming (HPs have their own software. server 2003 & 2008 can do it as part of the OS)

This works on any switch as it basically assigns multiple IPs and shares the load out automatically.

If your switch is capable, there are proper NIC teaming systems that synchronize the connection with the switch. These only work if the switch can handle it though.
let us know the make/model of the switch and I'll see if it can do it. If not, let us know what server OS and we can point you in the right direction.

Nexus 7k and a Open Solaris box.

I'm looking for more what needs to be done on the 7k. I see lots of articles for switch to switch but not switch to sever configs.

sorry mate. Solaris & Nexus aren't my forte.
Click 'request attention' to send requests to more experts but I'd recommend adding some 'tags' and maybe changing zones first to ensure you reach the experts with knowledge of the systems you need help on.

On the switch, in interface config mode use the command "channel-group 1 mode active" for an LACP etherchannel or "channel-group 1 mode on" to create it manually.
