+## Cluster Backups
+
+You must add the following snippet under the `manifests.volume-snapshot-class` field if you are using 
+Portworx as your CSI layer on a cluster deployed to a MAAS environment. 
+These labels ensure that the <VersionedLink text="Volume Snapshot Controller" url="/integrations/packs/?pack=volume-snapshot-controller" /> pack installs correctly.
+Refer to the <VersionedLink text="Create Cluster Backup" url="/clusters/cluster-management/backup-restore/create-cluster-backup" /> 
+guide for further information.

+This section lists resource requirements for {props.edition} for various capacity levels. In {props.edition}, the terms _small_,
+_medium_, and _large_ are used to describe the instance size of worker pools that Palette is installed on. The following
+table lists the resource requirements for each size.

+:::warning
+
+The recommended maximum number of deployed nodes and clusters in the environment should not be exceeded. We have tested
+the performance of {props.edition} with the recommended maximum number of deployed nodes and clusters. Exceeding these limits
+can negatively impact performance and result in instability. The active workload limit refers to the maximum number of
+active nodes and pods at any given time.

+The Spectro manifest requires approximately 10 GB of storage. {props.edition} deployed clusters use the manifest to identify what images to pull for each microservice that makes up {props.edition}.
