Requirements for the GUI components

The server on which you install the GUI components of Network Manager must meet the following hardware requirements.

Long-term disk space guidance for all GUI components and related products

For a production system that you intend to use for some time, you must have enough additional disk space to store files that are generated by product operation, such as rollback files. If you install the Network Manager GUI components, Dashboard Application Services Hub, Cognos Analytics, and Tivoli Netcool/OMNIbus Web GUI, you need at least 100GB space on the partition where the products are installed.

Hardware requirements for installing Network Manager GUI components

To install the Network Manager GUI components, your server must meet the following requirements:

5.5 GB hard disk space.
A minimum of 4 GB DRAM.
Note: The installer checks to ensure a minimum of 3 GB DRAM is available to accommodate demonstration and educational system deployments. However, a minimum of 4 GB DRAM is required in production environments.
500 MB in the /tmp directory.
DVD drive if not installing from download.

Hardware requirements for installing Cognos Analytics

To enable network management reports, you must have Cognos Analytics installed. Cognos Analytics is an optional component that needs to be installed separately to be able to use the reporting feature of Network Manager.

Review the hardware requirements for Cognos Analytics to make sure you meet your performance requirements.

Important: Ensure that you have at least 17GB of free space in the location where you want to install Cognos Analytics.

For detailed information, refer to the information about hardware requirements for your version of Cognos Analytics in the Cognos Analytics Knowledge Center at: https://www.ibm.com/support/knowledgecenter/SSEP7J.
