I am cross posting this here. Originally posted over in the resources section of the TrueNAS Forum. Figured some folks here might be interested.

This resource is meant to be a series. Part 1 will cover both the theory behind what I mean by Datacenter-in-a-box and also include the most primitive version of a practical application of that theory. I welcome any and all feedback, and I will post errata here and give due credit to anyone who assists in that endevour.
Part 2 will cover some additional security concepts and hardening of the system as it is, including identifying and rectifying the flaws in the design in Part 1 through an audit process.
Part 3 will shift from exclusively talking about storage concepts and move into the realm of applications, since SCALE is a hypervisor after all…
