Really slow network bandwidth between hosts on a 10Gb plane

Hi There

We have 3 blades (Dell M640) and one PowerEdge VRTX, VMware 6.7Update 1, We have spoke to Dell and there have recommended the following -  update all drives on esxi and update all vmware on the blades and chassis.

I am thinking we should update the vmware 6.7 to update 3 first and see how it goes, also I ran the following cmd  esxcli software vib list | grep qfle, and i see alot about the qfle3f driver for QLogic.

qfle3                          1.0.69.0-1OEM.670.0.0.7535516         QLC      VMwareCertified   2019-01-07

qfle3f                         1.0.51.0-1OEM.670.0.0.7535516         QLC      VMwareCertified   2019-01-07

qfle3i                         1.0.16.0-1OEM.670.0.0.7535516         QLC      VMwareCertified   2019-01-07

esxcli network nic list

Really looking for any recommendations or anyone else experiencing this issue before.

Thanks

John

While I can't speak to your performance issue specifically, I would suggest updating these drivers regardless as there are known issues with older releases of the driver that could cause a PSOD.
