This impacts large data sets of small files because each file is written to disk when transferred. In addition to the network environment, transfer rates to file systems are constrained by the destination server's disk access speed. Note: Signiant transfers account for partial packet loss and, within the 1-3% range, throttle the transfer speed to ensure transfer success. Lowering the bandwidth typically reduces the number of lost packets, helping to determine your optimal transfer speed. Transfers that fail to transfer a small percentage of packets can indicate that the bandwidth allocated exceeds network capacity. Ensure that your firewall is configured correctly and that both machines are connected to the network. Transfers with 100% packet loss typically indicates that the source or destination firewall is not configured correctly, or the servers are not able to connect to each other via the network.
You can also use the -n option to set a specific total transfer size instead of a transfer time: iperf3 -c 203.0.113.4 -u -p 49221 -n 2056M -i 2 -b 100M Interpreting Results -b - sets the bandwidth allocated to the testĬommand Example iperf3 -c 203.0.113.4 -u -p 49221 -t 60 -i 2 -b 100M.
Download and install iPerf on the server.Connect to the destination server using SSH or another remote access tool.The destination, typically an SDCX server, can be configured to receive packets via iPerf to determine if firewall rules are correctly configured and the maximum achievable transfer speed and bandwidth. Configure your firewall as required.Äownload iPerf for your operating system on both the transfer source and destination. Note: If your services cannot be stopped, tests can be performed using ports other than those used for file transfer. Stop your Signiant services by running siginit stop at the command line. This test should be performed between the source and destination using ports required for data transfer, either prior to server installation, or by stopping Signiant services on both servers to conduct the test. Signiant recommends using iPerf to test the maximum bandwidth and speed achievable between a source and a destination by sending packets over a network. It can be helpful to determine the fastest achievable transfer speed based on bandwidth throughput when determining potential transfer speed.
