Before file systems on PowerStore appliances (only available for PowerStore T Unified models) are configured, you must create a NAS server. A NAS server is a virtualized network-attached storage server that uses SMB, NFS, FTP, or SFTP protocols to catalog, organize, and transfer files within file-system shares and exports. A NAS server, the basis for multitenancy, must be created before you can create file-level storage resources. A NAS server is responsible for the configuration parameters on the set of file systems that it serves. To create, view, manage, or delete NAS servers, use the Storage > NAS Servers page in PowerStore Manager, as shown in the following figure.
