Hi All,
Just installed ESX5i on a DELL R320 with 10GbE PCI NIC connected to SFP+ switch.
ESX has correctly picked the NIC and speeds 10000 full etc. but the VM's are showing 1GB and being connected to Intel(R) PRO/1000MT Network Connection.
Should I be worried? This is the first machine on the backbone so I can't test a physical transfer between machines at the moment.
TIA

Welcome to the COmmunity - What you are seeing is correct the virtual NIC currently will show up as a 1 GB within the guest OS -
Thanks David - that's put my mind at rest.
If you set your vNIC to the "vmxnet3" type, it will show as 10GbE to the guest OS.
Note as above, this is just cosmetic though.
Hi Josh,
I can't find where to change this - can you let me know perhaps?
Many thanks for your reply.

I've sorted this now.
Many thanks for your help.
I have this setup as a vmxnet3 nic but my througput NEVER reaches 1 gig on my 10 gig NIC - I have both Broadcom quad 10 GB Nics on some of my hosts and I have INTEL NICs on other hosts (10 gig) NONE of my vmware hosts will go above 1/5 GB throughput. I tried Jumbo frames, I tried turning off promiscous mode, I tried disabling TSO, I ensured I was running only IPV4, I tried reading through endless blog and q/a's about the subject - but VMWARE is strangely silent - and if anyone ever figured this out - they are not talking. I can honestly say I am VERY frustrated. I will open a support ticket to VMware on this issue but - I SHOULD be able to find a definitive solution somewhere. REALLY frustrating. It shouldn't be rocket science to have quad 10 gig physical NICs and VMWNET3 vms that can actually perform at better than 1 gb speeds - prior to tweaking around, I wasnt even getting 100 meg! a 300 gig test robocopy lasted nearly 4 hours!!! It was actually SLOWER than my 1 GIG pre update test!
Really? Is this drama necessary? If vmware support gets an answer - POST IT SOMEWHERE!!!!!!!!!! How hard is that?
