How to perform a Cloud Harmony Test?

This article applies to:

  • Product edition: Phoenix Cloud
  • Feature category: Configuration

Overview

Network throughput and latency are important cloud performance characteristics. To analyze the overall network performance, these characteristics need to be tested from the inSync Client/Phoenix agent systems to inSync/Phoenix cloud services.

This article provides to steps to capture the network performance from a inSync Client/agent system to inSync/Phoenix Cloud.

Perform cloud harmony test

To get the cloud harmony results:

  1. Go to https://cloudharmony.com/speedtest#.
  2. Enter Amazon EC2 - <storage region name> under Test your connection to these services.
    For example, Amazon EC2 - ap-southeast-1 or Amazon EC2 - us-east-1, where ap-southeast-1 or us-east-1 is the storage region name.
  3. To get the storage region:
    1. Login to Phoenix Management Console and
    2. Go to Storage and note the storage region name after the underscore.
      For example:
       <Storage Name>_<Region Name>
      Druva-Test_us-east-1, where storage region is us-east-1

    Expand the Test Options list and select Downlink, Uplink, and Latency test types and click Start.
    • The first two columns represent the Uplink and Downlink information of the selected services (Amazon EC2 - ap-southeast-1).

    • The first column lists the average of six tests with a standard throughput between 256 KB to 10 MB per two threads for both uplink and downlink respectively.

    • The second column lists the average of 12 tests with throughput between 1 KB to 128 KB per four threads. For example,  Average Uplink speed is 3.01 Mb/s and downlink is 1.74 Mb/s.

    • The third column shows the overall latency from the server to the selected service. For example, latency from the server to Amazon EC2 s at 282 ms.

      Note: The backup and restore performance depends on a lot of environment variables including but not limited to network throughput and latency, file distribution, and machine performance 
  4. The following details are displayed on completion of the test.

    • Service (Lists the service name with the storage region. For example: Amazon EC2 - ap-southeast-1.)

    • Throughput (uplink & downlink) [256 KB - 10MB / 2 threads] 

    • Throughput (uplink & downlink)  [1-128 KB / 4 threads] 

    • Latency

    The output has three columns with default configuration selected on the previous screen. 
  5. Hover the mouse over the dots displayed in the first two columns to view additional details.
