Rackspace zone recommendations in OpenStack Configuration Reference - kilo

[tmaretzki]

The information on the Rackspace zone recommendations page seems to contradict the information of the parent page located at http://docs.openstack.org/kilo/config-reference/content/swift-zones.html. For example:

From the parent page, "In small clusters (five nodes or fewer), everything is normally in a single zone."

From the linked page, "... Rackspace recommends that you set up at least five nodes. Each node is assigned its own zone (for a total of five zones), which gives you host level redundancy."

So for a six node, single cab deployment of swift, is it one zone or six?

IMHO, the parent link of the doc suggests an example of small cluster which has a single zone and 5nodes or less. The linked page provides the default recommendation of Rackspace which says to use 5node cluster with each node having a single zone for the sake of host redundancy.

So if you have a single cab deployment of swift, based on Rackspace recommendation you can use six zones or if the production environment is not going to use any more additional storage use the single zone six node version.

Totally, completely based on the requirement of the production environment.
