-## Shared NFS
-
-Shared NFS leverages native NFS capabilities to provide scalable **ReadWriteMany (RWX)** volumes, allowing multiple containers or nodes to access the same persistent storage simultaneously. This enables efficient shared storage in Kubernetes environments and follows a standard client-server architecture, where a node can act as both an NFS server and a client. </br>
-This setup offers better scalability and flexibility than traditional NFS systems that rely on a single server. It also simplifies storage by allowing remote file access as if the files were local, reducing the need for data duplication </br>
-
-**Prerequisites** </br>
-
-- NFS Version Compatibility: NFS v4.2 is required for optimal performance and full feature support.</br>
-- System Configuration: Ensure that `nfs-server` and `nfs-mountd` services are active on all participating worker nodes.</br>
-- Driver Requirements: Shared NFS is supported starting from driver version v2.14. Current integration is available with iSCSI-based backends, with plans to expand support to additional storage protocols in future releases.
-
-To enable Shared NFS, define the `shared-nfs: RWX` parameter in the parameters section of your StorageClass. This activates `RWX` support using the NFS backend. Refer to the example below for implementation details
-
-**Example StorageClass  for Shared NFS**
-
-```yaml
-apiVersion: storage.k8s.io/v1
-kind: StorageClass
-metadata:
-    name: powerstore-sharednfs-sc
-provisioner: csi-powerstore.dellemc.com
-reclaimPolicy: Delete
-parameters:
-  arrayID: <array-id>
-  shared-nfs: RWX
-  csi.storage.k8s.io/fstype: ext4
-provisioner: csi-powerstore.dellemc.com
-reclaimPolicy: Delete
-volumeBindingMode: WaitForFirstConsumer
-
-```
-> **Note:** </br>
-Performance and scalability are influenced by factors such as the array appliance, network latency, and available Kubernetes resources. The current solution is designed to handle a significant number of volumes, with ongoing enhancements planned to support even greater demands in future releases. All testing is conducted using industry-standard methodologies, including stress testing frameworks such as the OpenShift LUN stress test.

 ## Multi NAS Support
 The CSI PowerStore driver version 2.14.0 and later introduces multi-NAS support. This feature allows users to specify multiple NAS servers within a single storage class. By supporting multiple NAS servers in a single storage class, customers can create 2000 filesystems per PowerStore system across multiple NAS servers configured in SC. Previously, multiple storage classes were needed to support this configuration.

 - Ensure that your nodes support mounting NFS volumes if using NFS.
 - For NVMe support the preferred multipath solution is NVMe native multipathing. The [Dell Host Connectivity Guide](https://elabnavigator.dell.com/vault/pdf/Linux.pdf) describes the details of each configuration option.
