NIC Teaming and Switch Link Aggregation

We currently have several HP servers, each with either 2 or 4 NICs combined to form a team.

However, at the switch end there is no Link Aggregation setup on the ports.

Whilst this obviously works, my understanding is that we won't be getting the maximum throughput TO the server, only FROM it - is this correct?

And if so, are there any other settings that should be set to maximise data flow through a NIC Team / Link Aggregation setup?

Yes, configuring Link Aggregation or Fast Ether Channel/Gigabit Ether Channel on the switch side is required to achieve the bandwidth you are hoping for. Teaming via the NIC software only provides redundancy and load balancing for a "many to one" configuration (e.g. webserver).

Which switch vendor and NICs are you using?

Thanks!

Thanks for the quick response

The NICs are HP Ethernet 1Gb 4-port 366i Adapter

The Switch is a Linksys SRW2048

I've also seen some comments regarding not using 'Auto Negotiation' for the speed, but instead setting it to 1000/full on both the switch and NIC - is this correct?

Any other settings that I should be looking at?

ALB is actually better performance-wise than LACP in a HP team.  Your throughput should be ok both ways.
