Planning for the High Availability CommServe Host Setup

Verify that the prerequisites needed to setup the environment are available before setting up the High Availability CommServe Hosts.

Note: Identical software must be used for setting up the production and the standby CommServe hosts. Ensure that the Operating System and SQL Server version (including service packs) are identical in the both the production and standby hosts..

Hardware

You must have the necessary hardware for setting up the CommServe server on the production host and the standby hosts. More than one standby host is supported.

For more information on the hardware specification for the CommServe server, see Hardware Specifications for the CommServe Server.

Operating System

The High Availability CommServe Hosts can be set up on all operating systems supported by the CommServe server.

For more information on the supported operating systems, see CommServe Server: System Requirements.

Note: High Availability CommServe Host is not supported when the CommServe server is configured with Microsoft Failover Cluster.

License Requirements

  • CommServe Server

    No special licenses are required for setting up the CommServe server.

  • SQL Server Agent

    You must have two Microsoft SQL Server agent licenses, one for the production CommServe host and the other for the standby CommServe host.

For information about licensing, see the Commvault Licensing Program Guide.

Installation Packages

The following Commvault installation packages are required for setting up the production host and the standby CommServe hosts:

  • CommServe

    Additional packages are installed by default during the CommServe installation. For more information, see the Additional Packages Installed with the CommServe section in Preinstallation Checklist for the CommServe.

  • CommServe Failover

    The SQL Server agent and the CommServe Failover package are automatically installed in a new instance. (No additional user intervention is needed.)

Firewall and Network Requirements

By default, this solution requires that all clients communicate with the CommServe server using a proxy. To facilitate communication between the clients and the CommServe, verify the following conditions:

  • Both the active host and the passive CommServe hosts can reach the tunnel ports that are associated with the SQL clients in both the active host and the passive CommServe hosts.
  • If the SQL clients are used as the proxy, verify that all the clients in the CommCell environment can communicate with the port and hostname of the SQL clients in both the active host and the passive CommServe hosts.
  • If a dedicated proxy is already set up and available in your environment, use this dedicated proxy to communicate with the CommServe server.
  • To failover over to a CommServe host in the cloud, or if there is a firewall between the active host and the passive CommServe hosts, see Setting Up a Standby CommServe Using TPPM.
