Pick a task on the left
Each task opens with the steps to follow, the prerequisites that must already be in place, and a diagram of how the objects relate to each other, so you can see what a task actually builds rather than only what you type.
Work from task 1 to task 214 in order and you will have chosen an architecture, sized it honestly, built vSAN clusters including stretched and two-node, written storage policies and watched them resynchronise, published file and block services from vSAN, encrypted a cluster and rekeyed it, attached non-vSAN storage, then broken all of it on purpose and diagnosed every fault. Tick tasks off as you go; progress is kept in this browser.
Keyboard: J and K, or the arrow keys, move between tasks. D marks the open task done.
