, the NAS server uses the RPCSEC_GSS security framework and Kerberos authentication protocol to verify users and services. Security options Secure NFS supports the following security options: ● krb5: Kerberos authentication ● krb5i: Kerberos authentication and data integrity by adding a signature - Dell PowerStore 1200T | EMC PowerStore Configuring NFS - Page 7

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 1200T | EMC PowerStore Configuring NFS - Page 15
systems and NFS Exports overview While creating File Systems and NFS Exports, it is helpful to note the following: ● A NAS server must be configured to support NFS protocol before creating a file system. ● You can choose to add NFS Exports the first time you create the file system, or you can add - Dell PowerStore 1200T | EMC PowerStore Configuring NFS - Page 16

Modify file-level retention Retention period parameters can be set at file system creation or later and can be modified. Modifying retention period parameter does not affect files that are already locked. 1.

non-peak production hours to avoid impacting file system operations. NOTE: You cannot enable quotas for read-only file systems. NOTE: Quotas are not supported in VMware file systems. Types of quotas There are three types of quotas you can put on a file system. Table 2. Quota types Type User - Dell PowerStore 1200T | EMC PowerStore Configuring NFS - Page 22
Table 3. Hard and Soft Limits (continued) Type Descriptions The user is alerted when the soft limit is reached, until the grace period is over. After that, an out of space condition is reached until the user gets back under the soft limit.

To enable CEE CEPA support, you must enable CEE CEPA and create an Event Publishing Pool on the NAS server. An Event Publishing Pool defines the CEPA servers and - Dell PowerStore 1200T | EMC PowerStore Configuring NFS - Page 26
Create an event publisher After configuring publishing pools, create an event publisher to set the response to the different event types. NOTE: Event publishers are created at the system level and one event publisher can be associated with multiple NAS servers. 1. Select Storage > NAS Servers. 2.
