By using a performance benchmark tool, you can test the PVRDMA network connection between a vSphere Bitfusion server and client.
- Verify that your vSphere environment has a PVRDMA distributed network configured. For more information, see the vSphere Networking documentation.
- Verify that you have configured a vSphere Bitfusion server to use PVRDMA. See Configure a vSphere Bitfusion Server to Use PVRDMA.
- Verify that you have configured a vSphere Bitfusion client to use PVRDMA. See Configure a vSphere Bitfusion Client to Use PVRDMA.
- Install the Performance Tests (perftest) package with version 4.4.0-11 for your Linux operating system.
The package includes performance benchmark tools, such as ib_send_bw and ib_send_lat. The 4.4.0-11 version is compatible with the perftest package that is installed on your vSphere Bitfusion servers.
- Ubuntu 20.04
sudo apt-get install -y perftest
- CentOS 8 and Red Hat Linux 8
git clone https://github.com/linux-rdma/perftest.git cd perftest git checkout v4.4-0.11 ./autogen.sh ./configure make clean && make V=1 sudo make install
- Ubuntu 20.04
- From your vSphere Bitfusion server, run the ib_send_bw --report_gbits command.
- From your vSphere Bitfusion client, run the
ib_send_bw --report_gbits BF_server_IPcommand, where BF_server_IP is the IP address of the virtual machine of your vSphere Bitfusion server.
Both your vSphere Bitfusion server and client create a bandwidth report.
What to do next
- Check your PVDRMA configuration.
- Run the ibv_devinfo command on your vSphere Bitfusion client. If the result displays a
PORT_DOWNstate for the RDMA ports of your network adapter, see PVRDMA is Not Working on a vSphere Bitfusion Client in the VMware vSphere Bitfusion User Guide.
