Description

This enhancement to the CSI-PowerStore driver enables support for multiple NAS servers within a single storage class, overcoming the 125 filesystem limit by scaling up to 2000 filesystems. It allows Kubernetes administrators to efficiently provision up to 2000 PersistentVolumes, with intelligent NAS server selection based on available capacity.

How Has This Been Tested?

i. Ran volumeio longevity tests using NAS server nas8 and nas9 and volumes got scaled to both NAS servers as shown in attached image:
