Planning & Sizing

What cluster to build and what to build it from: the decisions to make before you buy hardware, and the arithmetic that supports them.

Sizing the cluster calculates the figures: what the workload demands, what redundancy costs, and how much memory and raw space those choices need. Hardware describes the machines that match these figures, role by role. Network covers what the cluster requires from the links between those machines. Platforms covers what the machines run on. Multiple locations covers what changes when the cluster is to run in more than one place.

Deployment covers installing what you decide here.
