How Do I Measure the Network Performance Before the Migration?

Background

Poor network performance may prolong the migration or cause migration failures. SMS can help you measure the network performance before the migration.

It takes 4 to 5 minutes to complete the measurement. To accurately measure the network performance, the migration rate limits you configure are not applied during the measurement, and more network resources may be used. You are advised to evaluate the actual resource usage on the source server to ensure that your services run properly.
You must make sure that inbound ICMP traffic is allowed in the security group of the target server.

Procedure

When you configure the migration task, on the Configure Basic Settings page, set Measure Network Performance to Yes. During the full migration, SMS will generate a subtask Measure the network performance.

Measurement Results

This subtask measures four major network metrics packet loss rate, jitter, latency, and bandwidth as well as memory usage and CPU usage that impact the network performance. The measurement results are displayed in green, orange, and red, which indicate good, medium, and poor respectively. After the measurement is complete, SMS will display how well your network is performing and estimate how long the migration will take.

The evaluation result represents only the network performance during the test.
The migration duration is estimated when the migration rate limits are not applied and is for reference only. In addition to the migration network, the migration duration is affected by many other factors, such as the number of small files on the source server, network fluctuation, disk read/write speed, and network traffic limit. A more reliable indicator is the remaining migration time displayed in the task list.
