Dear community,
I've setup Link Aggregation to the best of my knowledge, but I have some questions I'm hoping you guru's can answer.
Main problem/concern: Even though I should be having the equivalent of ~3Gbit/s network connection towards my LAN, I can only squeeze out exactly 1Gbit/s.
Please see the attached pictures of my network config in ESXi.
Questions:
1) According my screendumps, does everything look ok?
2) Do I need to tick the boxes in the "NIC Teaming" tab on the Virtual Machine Port Group also(see picture 4 below), or is this inherited from the vSwitch?
3) Using a VM with VMXNET3 adapter, I can only get 1Gbit/s throughput when testing, is this normal?
System info:
ESXi 5.1.0, 914609
Supermicro X9-SCM-F
16GB ECC
Xeon E1220
2 x Onboard NIC's
1 x Dual Port PCIe x4 NIC
1 x NIC for mgmt
3 x NIC for VM's (Cabled up to my Cisco SG-200 switch and setup as LAG(without LACP)
Any help would be much appreciated.
Best regards
Jim
To be able to make full use of LACP you need to use vDS with ESXi 5.1. For other versions/editions take a look at http://kb.vmware.com/kb/1004048 for the limitations.

How are you testing, exactly? This can provide a ton of insight.
Thanks André for your tip.
Although I only have a single ESXi host, will vDS work? Also are you saying that it's not possible to reach more than 1Gbit/s throughput using a normal vSwitch with IP hash teaming?
Thanks for you assistance so far.

Hi Matt,
Good point.
I have an HP Microserver with Windows 2012 on it. 3 NIC's and setup for LACP. This should provide approximately 3Gbit/s speeds.
I'm then copying a testfile from a W2K8 VM with VMXNET3 vNIC. The testfile in located on a SSD.
Thanks
Jim
Your test is insufficient.
IP hash load balancing means that any given IP hash (.e.g connection between 2 machines) will only go over a single card. To effectively use multiple cards with IP hash, you need MULTIPLE clients with different IP addresses to hit a combined 3GBit. Any single connection will be limited 1 GBit.
Thanks Matt,
That gave a lot of insight, I'll try testing some more.
