Data Domain network speed test with iperf

If you want to test network speed between your Data Domain (i.e. to troubleshoot replication issue) use iperf tool.

Below example test speed from ddve-02 (source) to ddve-01 (destination).

For iperf to work you have to ensure the TCP port 5001 is open on destination Data Domain.

On destination Data Domain you have to start iperf as server
sysadmin@ddve-01# net iperf server

On source Data Domain start iperf as client
sysadmin@ddve-02# net iperf client 192.168.12.21 duration 60 interval 10

192.168.12.21 - destination Data Domain IP
duration 60 - test duration 60 seconds
interval 10 - report speed results every 10 seconds

Example iperf output

sysadmin@ddve-01# net iperf server
