Which V3 versions can use NAS?
V300R001 supports only SAN. Both SAN and NAS are supported by V300R002 and later versions. The following model is special. 1) NAS is not supported by OceanStor 2800 V3; 2) NAS is not supported by OceanStor 2600 V3 Video Surveillance Edition; 3) NAS is only supported by OceanStor 2200 V3 with conditions: V3 version >= V300R006 and Memory Cache >= 16GB.

How is IP failover configured for V3 series unified storage?
IP failover allows rapid service migration from the faulty port to another available port of the same type without interrupting host services and the process is transparent to users. After the faulty port recovers, it takes over its services again. For details about how to configure IP failover, see IP Address Failover Deployment Guide.

What Are Permission Management Modes Provided for the File System Shared by the Clustered NAS Storage System?
The clustered NAS storage system supports the CIFS share, NFS share, FTP share, and HTTP share. For the CIFS share, the authentication modes include local authentication and domain authentication. The locally authenticated permissions are managed based on local groups. The domain authentication permissions are managed based on files which are configured by the AD domain administrator after the clustered NAS storage system is added to the AD domain. For the NFS share, the permissions on the file system are managed and controlled by providing a specific client or network group in NFS mode. Sharing the file system to the network group requires that the clustered NAS storage system be added to the LDAP domain or NIS domain. Therefore, you can manage the permission on the file system by configuring and managing the network information (user information or group information) of the LDAP domain server or NIS domain server. For the FTP share, you can assign different permissions to users for one directory or folder. You can set the maximum number of access threads of an IP address and setting the ports of the FTP server. This function enables users to flexibly configure the FTP service and maintain the FTP server. For the HTTP share, users are allowed to access the file system through HTTP. HTTP is a protocol used for servers to transfer hypertext to local browsers.

Method used to configure service IP addresses for an OceanStor V3 storage system
Method used to configure service IP addresses for an OceanStor V3 storage system: In the rear view of the device displayed in OceanStor DeviceManager, click the port whose IP address you want to modify and modify the IP address.

In What Way Does the Clustered NAS Storage System Manage Permissions on an NFS Shared File System?
The clustered NAS storage system manages and controls permissions on an NFS shared file system by allowing only a specific client or network group to access this NFS shared file system. When configuring an NFS share in an LDAP domain or NIS domain, you need to add the clustered NAS storage system to a corresponding domain. When a client tries to access the NFS shared file system, the LDAP server or NIS server functions to authenticate the client and determine whether they have the permission on the NFS shared file system.
