or both. NOTE: If you select SMB and an NFS protocol, you automatically enable the NAS server to support multiprotocol. Unix Directory Services (Naming Services) You can configure the naming services with a combination of Local Files and NIS, or LDAP. Refer to the following sections for configuring - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 8

It is recommended that you set up a minimum of two NTP servers per domain to avoid a single point of failure. ● A UNIX Directory Service hosts defined on NFS export access lists.

Disabled is on, slide the button to change to Enabled. 3. In the Unix Directory Service drop down, select NIS. 4. Enter an NIS Domain and add the IP Addresses for the NIS servers. 5. Select Apply. To troubleshoot issues with configuring a UDS using NIS, ensure that the NIS server domain and server - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 10
. To troubleshoot issues with configuring a UDS using LDAP, ensure that: ● The LDAP configuration adheres to one of the supported schemas, the following steps: 1. Select Storage > NAS Servers > [nas server] > Naming Services > Local Files. 2. For each type of local file, select the down arrow - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 11
NAS server only. Passive mode FTP is not supported. FTP access can be authenticated using the same Kerberos authentication protocol to verify users and services. If the NAS server has been configured with a custom realm before configuring security in PowerStore. If the NAS server has been configured - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 12
server account on the NAS server, follow these steps before configuring Kerberos in PowerStore. The steps assume that you want to use myrealm.windows.dellemc.com (AD) of the windows domain windows.dellemc.com. 2. Register the service SPN on the computer account you created: C:\setspn -S nfs/myrealm. - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 13
Configure Kerberos security for the NAS server You can configure the NAS server with Kerberos security. If configuring for NFS, DNS and UDS must be configured for the NAS server and all members of the Kerberos realm must be registered in the DNS server. If using a NAS server that is configured for - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 14
helpful to note the following: ● A NAS server must be configured to support NFS protocol before creating a file system. ● You can choose to metadata upon creation. For example, after creating a 100GB thin file system, PowerStore T model immediately shows 1.5GB used. When the file system is mounted - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 15
storage system. ● Each NFS share must have a unique local path.PowerStore automatically assigns this path to the initial export created within a new system. Only snapshots are supported for protection for file systems. Replication is not supported on file system. 8. Review the summary and click - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 16
● Local Path must correspond to an existing folder name within the file system that was created from the host-side. ● The value specified in the NFS Export Details, Name field, along with the NAS server name, constitutes the name by which hosts access the export. ● NFS export names must be unique at - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 17

5 More file system features This chapter includes the following information. Topics: • File system quotas File system quotas You can track and limit drive space consumption by configuring quotas for file systems at the file system or directory level. You can enable or disable quotas at any time, - Dell PowerStore 500T | EMC PowerStore Configuring NFS Exports - Page 20
