1. Login, go to the Administrator page.

2. Click Marketplace > OperatorHub to enter the OperatorHub page.

3. Find the Alauda Container Platform Storage Essentials, click Install, and navigate to the Install Alauda Container Platform Storage Essentials page.

   Configuration Parameters:

   Parameter	Recommended Configuration
   Channel	The default channel is stable.
   Installation Mode	Cluster: All namespaces in the cluster share a single Operator instance for creation and management, resulting in lower resource usage.
   Installation Place	Select Recommended, Namespace only support acp-storage.
   Upgrade Strategy	Manual: When there is a new version in the Operator Hub, manual confirmation is required to upgrade the Operator to the latest version.

#Deploy Storage

1. Go to Administrator.

2. In the left navigation bar, click Storage Management > Local Storage.

3. Click Configure Now.

4. On the Install Operator wizard page, click Start Deployment.

   • When the page automatically proceeds to the next step, it indicates that the Operator deployment was successful.

   • If the deployment fails, please refer to the interface prompts for resolution. Then click Clean Up and redeploy the Operator.

5. On the Create Cluster wizard page, add devices.

   To use Selection Device, install Alauda Container Platform Local Disk Provisioner first. It provides the device discovery results used by the LVM Storage wizard. See Install Local Storage.

   Selection Device is disabled until that operator is installed. Legacy Selection Device does not require Alauda Container Platform Local Disk Provisioner; it lists disks on the node without discovery results.

   Parameter	Description
   Select Node	Node with at least 1 bare disk.
   Device Class	Each device class corresponds to a set of storage devices with the same characteristics. It is recommended to fill in the name based on the disk nature, such as hdd, ssd.
   Device Type	Only disk types are supported.
   Storage Device	For example, /dev/sda. If there are multiple disks, they can be added one by one.
   Snapshot	When enabled, it supports creating PVC snapshots and using the snapshots to configure new PVCs for quick backup and recovery of business data. If the snapshot was not enabled when creating the storage, you can still enable it as needed in the Operations section of the storage cluster details page. Note: Before use, please ensure that the Volume Snapshot Plugin has been deployed for the current cluster.

   • Click Next. When the page automatically proceeds to the next step, it indicates that the cluster deployment was successful.

   • If the creation fails, please refer to the interface prompts and clean up resources in a timely manner.

6. On the Create Storage Class wizard page, configure the relevant parameters.

   Parameter	Description
   Name	The name of the storage class. It must be unique within the current cluster.
   Display Name	A name that helps you identify or filter, such as a Chinese description of the storage class.
   Device Class	The device class is a way to categorize storage devices in TopoLVM. Each device class corresponds to a set of storage devices with the same characteristics. If there are no special requirements, you can use the Auto-Allocated device class from the cluster.
   File System	- XFS is a high-performance journaling file system adept at handling parallel I/O workloads, supporting large file processing and providing smooth data transfer. - EXT4 is a journaling file system in Linux, offering extent file storage methods and supporting large file processing. The file system can reach a capacity of 1 EiB, with a maximum supported file size of 16 TiB.
   Recycling Policy	The recycling policy for persistent volumes. - Delete: When the persistent volume claim is deleted, the bound persistent volume is also deleted. - Retain: Even if the persistent volume claim is deleted, the bound persistent volume will still be retained.
   Access Mode	ReadWriteOnce (RWO): Can be mounted by a single node in read-write mode.
   Allocation Project	This type of persistent volume claim can only be created in specific projects. If no project is assigned temporarily, the project can also be Updated later.

7. Click Next and wait for the resource creation to complete.
