Understand the Container Cluster Management storage architecture.
Within CCM, a Persistent Volume (PV) represents a segment of storage that an administrator has provisioned for you, or that has been automatically set up using Storage Classes.
Think of it as a durable container for your data, designed to outlast any individual Pods in your cluster. You have the flexibility to have Persistent Volumes provisioned either statically or dynamically.
With static provisioning, your cluster administrator pre-arranges a set of PVs with defined storage capacities that remain at your disposal until they are explicitly removed. Dynamic provisioning, however, is like having a responsive storage solution that automatically creates storage resources whenever your Persistent Volume Claims (PVCs) demand them.
The value for you lies in the Persistent Volumes' ability to support your stateful applications—those that need a reliable storage backend that won't forget data when a Pod goes away. PVs empower you to manage your storage needs declaratively, freeing you from worrying about the nitty-gritty of storage infrastructure.
The Storage feature in Kyndryl's Container Cluster Management provides a consolidated view and management options for Persistent Volumes, Persistent Volume Claims, and Storage Classes. Ensuring a proper configuration of this feature empowers users to maximize the utilization and management of storage resources within their container clusters.
To view the different storage data, follow these steps to access the data you need:
Upon successful authentication, proceed to the CCM main dashboard. This serves as the central hub for all cluster management activities.
In the dashboard, locate the
Cluster table
, positioned towards the bottom of the interface. This table lists all the clusters available under your management.
Identify and choose the desired cluster by selecting it within the
Cluster table
. This action will direct you to a detailed view of the selected cluster.
Within the cluster details view, navigate to the
Storage
tab. Here, you will find options to view and manage Persistent Volumes, Persistent Volume Claims, and Storage Classes associated with the selected cluster.
Persistent Volumes
View the available persistent volumes.
For a detailed insight, either click on the specific row or select the

option.
Persistent Volume Claims
Displays the available Persistent Volume Claims.
Namespace-specific claims can also be viewed.
For detailed information, click on the respective row or opt for
