Hi Alex, I've tried 2 EXPI9301CT on win2k8 R2 Enterprise and was able to create LACP group, just make sure to install the driver. You can get the driver from the link below:
Other teaming mode can also be configured such as load balancing, fault tolerance, for details of each teaming mode, kindly check out the link below:
Hope this help.
This was of great help! I was just searching if I can buy cards for low-end server with aggregation capabilities. Now I know that I can and that it will work.
