I have three hosts, each with 2 10gb nics. I've been using 1 port for storage on each host.
I discovered that all three of the storage nics were actually running at 1gb, and seem to have fixed this using the command:
After running that command I can see the nics are showing Speed 10000 Mb/s:
However, the transfer speed still seems to be running at 1gb for some reason:
CAT6 is in use and all cables are 6ft long. Switch is definitely 10gb on each port. Verified all three hosts show nic at 10000Mb/s. All hosts tested between each other with same result.
Is there something that needs to be restarted before the 10gb speed will be used?
