Configure Smart Analytics for high availability

This section provides instructions for you to configure Service Manager Smart Analytics for high availability.

Overview

To reduce potential down time, it is recommended that you configure Smart Analytics for high availability. The following diagram is an example architecture of Smart Analytics configured for high availability:

In this diagram:

  • Propel content2 is the failover content of Propel Content1 and vice versa.
  • Smart Search content2 is the fail-over content of Smart Search content1 and vice versa.
  • HTA content2 is the fail-over content of HTA content1 and vice versa.

Note

  • Smart Search data is distributed among groups, while content servers in a group are mirrored to each other as fail over backup. For better index and query performance, it is suggested to store no more than 3 million records for each content server. You can adjust the number of groups accordingly to fit actual scenarios. For example, if Smart Search would have 9 million records, at least 3 groups should be used for Smart Search, which means 6 content servers in total used as Smart Search content servers.
  • Propel and QMS are only supported as of Smart Analytics 9.50.
  • You can configure high availability for all contents or contents of a specific component only, for example, Smart Search contents.
  • The ports are provided only for reference. You can change the ports by modifying the corresponding configuration files.
  • You can locate the proxy and QMS servers on the same machine or different machines. However, it is recommended that the rest content servers be located on different machines. For example, Host 1, 2, 3, 4 and 13 in the diagram can be the same machine, while Host 5-12 different ones.

Configuration steps

To configure Smart Analytics for high availability as depicted in the diagram, follow these steps:

  1. Install and configure the proxies for high availability as needed.

    In the diagram, Smart Analytics uses four proxies to organize its contents: one main proxy and three level 2 proxies under the main proxy.

  2. Install and configure failover content servers by using the Smart Analytics installer or copying existing ones of Smart Analytics, as described below:
