Has anyone been able to use 40Gb interfaces with CHR and if so which ones and what hypervisor?
I know that in VMware ESXi , the vmxnet3 interface is not limited to 10-gig. It is purely a paravirtual optimized network driver/interface.
For me, testing testing two different CHR systems on the same VMware ESXi box, I can get throughputs in excess of 17 gig (faster than 10 gig).
The 10-gig restriction is the physical Ethernet interface.
I suppose that at the physical VMware ESXi network card you could play with bonding and LACP (and test/try all of the load/sharing protocols).
Or - Just find a 20 or 40 Gig network card that VMware ESXi supports.
You might want to google VMware ESXi 40 gig
In your VMware ESXi server at the CLI prompt, you can type in "esxcli network nic list" to see what current networks are installed in your VMware ESXi server. ((( This shows what is currently installed - not what is supported )))
