About Pods
11
For each zone, the administrator must decide the following.
How many pods to place in a zone.
How many clusters to place in each pod.
How many hosts to place in each cluster.
(Optional) If zone-wide primary storage is being used, decide how many primary storage servers to
place in each zone and total capacity for these storage servers. (Supported for KVM and VMware
hosts)
How many primary storage servers to place in each cluster and total capacity for these storage
servers.
How much secondary storage to deploy in a zone.
When you add a new zone, you will be prompted to configure the zone’s physical network and add the
first pod, cluster, host, primary storage, and secondary storage.
(VMware) In order to support zone-wide functions for VMware, CloudPlatform is aware of VMware
Datacenters and can map each Datacenter to a CloudPlatform zone. To enable features like storage
live migration and zone-wide primary storage for VMware hosts, CloudPlatform has to make sure
that a zone contains only a single VMware Datacenter. Therefore, when you are creating a new
CloudPlatform zone, you can select a VMware Datacenter for the zone. If you are provisioning multiple
VMware Datacenters, each one will be set up as a single zone in CloudPlatform.
Note
If you are upgrading from a previous CloudPlatform version, and your existing deployment
contains a zone with clusters from multiple VMware Datacenters, that zone will not be forcibly
migrated to the new model. It will continue to function as before. However, any new zone-wide
operations introduced in CloudPlatform 4.2, such as zone-wide primary storage and live storage
migration, will not be available in that zone.
3.3. About Pods
A pod often represents a single rack. Hosts in the same pod are in the same subnet. A pod is the
third-largest organizational unit within a CloudPlatform deployment. Pods are contained within zones,
and zones can be contained within regions. Each zone can contain one or more pods. A pod consists
of one or more clusters of hosts and one or more primary storage servers. Pods are not visible to the
end user.
