Vmware esxi 6.7 network configuration how to#
In this blog post, I showed you how to run iPerf on an ESXi server and find where bandwidth bottlenecks may be. I saw a slight drop in the bandwidth when I ran iPerf from the VDI client to the ESXi server and to virtual desktop, but the drop wasn’t dramatic and acceptable as network overhead. Because I took the screenshot as the test was wrapping up, the ControlUp screen shot shows slightly less than 0.90 Gb. Below is a table showing the results and ControlUp Console screenshots I took during the tests. To see how well my system performed I ran iPerf from my VDI client to a virtual desktop VM hosted on an ESXi host, then to the VDI client and the virtual machine, which was also running iPerf.
The speed of the network was limited by the 1 Gb NIC on the VDI Client that I was using since the ESXi host had a 10Gb NIC in it. The results showed that the maximum bandwidth between the two systems was 0.95 Gbps.
This started the client system ( -c) and connected to my iPerf server (10.0.0.21) iPerf ran a test for 10 seconds ( -t 10), showed the results in Gb ( -f g), and reported statistics every 5 seconds ( -i 5).

Once you have downloaded the bundle you can install it by entering:
Vmware esxi 6.7 network configuration software#
Although not supported – and you should not install unauthorized software on a production system – you can install iPerf by downloading the offline bundle from and copying it to your ESXi 6.7 server. If iPerf isn’t installed on your system you can install it as a VIB. iPerf3 is the latest iteration of iPerf (Note that I will refer to iPerf3 as “iPerf” in this blog). To check to see if you have iPerf installed on your ESXi host, SSH to your ESXi host and go to /usr/lib/vmware/vsan/bin and see if you have a file named iperf or iperf3. After having included iPerf with ESXi 6.5, VMware removed it in 6.7-but they’ve now added it back in 6.7U1. VMware strongly discourages installing any additional software on an ESXi host because doing so could have unintended consequences and interfere with the operation of both the hypervisor and the hosts on which the hypervisor resides. iPerf not only runs on many VDI clients but it also runs on some versions of ESXi.
For those unfamiliar with iPerf, it is a freely available, open source, multi-platform tool that creates a load between two systems and then reports the bandwidth, delay jitter, and datagram loss that can cause a network to perform suboptimally. This assumes that you have a tool that can measure the network bandwidth between the systems fortunately, iPerf is such a tool. To check this, you can run iPerf between a VDI client and an ESXi server, and between the VDI Client and the ESXi server on which the virtual desktop resides to see where the bandwidth limitations are. This is a good question as there are many situations in which knowing how much bandwidth a given host can handle can be very beneficial for instance, if you experience a loss in bandwidth capacity between an virtual desktop and a VDI client, or otherwise need to identify where a networking bottleneck may be occurring.
