Design Steps
Designing a cluster entails four sets of design decisions. You should:
Determine the overall mission for your cluster.
Select a general architecture for your cluster.

Selecting the hardware should be the final step in the design, but often you won’t have as much choice as you would like.

Chapter 3 describes hardware ...
