I'm in the middle of a trial and seeing a huge performance issue that seems to be limiting data to 100mbps.

Initially I tried enabling jumbo frames (on esxi, switches and in the tuning of Open-E ). I had also setup a balance-rr bond but in order to simplify it I have set it to standard MTU and 1 nic and seeing the same results.

I currently have 2 iSCSI vmkernel ports pointing at the Open-E server with round robin as the path and each nic is evently distributed.

All of the network ports are up at 1000gbps other than the main management interface which is 100mbps but we are not connecting to that IP for iSCSI.

Any hints, tips or suggestions would be appreciated.
