Before You Begin

Lightbits recommends that you plan to use two networking interfaces for the Lightbits cluster installation: one for control and another as a data storage node.

Before you begin, it is recommended to review the General System Requirements and Required Ports for Installation and Operation sections of this guide.

Note that:

• The data interfaces are pre-configured and accessible.
• To install the cluster software, you need an Ansible module, and Ansible application-deployment tool v9.1.0 or later.
• The Python netaddr module, which is used to represent and manipulate network addresses.
• There is support for multiple Ansible tags (for cleanup for example), by using comma-separated tags.
• Based on the placement of SSDs in the server, check if you need to allow cross-NUMA devices in the profile (you can find more on this in the Host Server Configuration section).

Also, review the data networking and NVMe drive placement of the servers. This will be important during the installation configuration phase.

The online installation requires an internet connection and the need to configure several files on your system. The file repository URL is accessible and the RPMs are updated. The data interfaces of each server must be pre-configured on the same subnet. Our subnet is 10.0.10.0/24 (if the data interfaces are not pre-configured, they can be configured later using Ansible).
