Installation Planning Table

The table below details a Lightbits cluster installed on three servers, with a connected client.

Server Name	Role	Management Network IP	Data NIC Interface Name	Data NIC IP	Data NVMe Drives	Journaling NVMe Drives
server00	Lightbits Storage Server 1	192.168.16.22	ens1	10.10.10.100	6	2

Note that:

The servers are running AlmaLinux 8.7 with kernel 4.18.0-425.19.2.el8; however, other OSs are supported with different build releases. For additional information, see General System Requirements.
The Lightbits RHEL release will be installed. Our Red Hat build supports Red Hat and AlmaLinux. For additional information, see General System Requirements.
We will install in Single Instance/NUMA/node mode; however, if the servers have dual or more NUMAs, we could also do a dual instance/NUMA/node installation. Examples for this will be provided.
