<para>This document describes each storage node as a separate zone in the
|
|
ring. It is recommended to have a minimum of 5 zones. A zone is a
|
|
group of nodes that is as isolated as possible from other nodes
|
|
(separate servers, network, power, even geography). The ring
|
|
guarantees that every replica is stored in a separate zone. This
|
|
diagram shows one possible configuration for a minimal
|
|
installation.</para>

<!-- we need to fix this diagram - the auth node isn't a thing anymore-->
