VNXe system requirements This the VNXe system using the Configuration Wizard, as described in the Installation Guide for your storage system. l You have used Unisphere or the VNXe - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 7
Users can store files on a VNXe NAS server in a Network Information Service (NIS) environment, but you cannot configure a VNXe NAS server as an to use link aggregation for high availability configurations. The VNXe system supports link aggregations that allow up to four Ethernet ports connected to - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 8
to forwarding mode. Do not use portfast on switch-to-switch connections. For link aggregation, network switches must have IEEE 802.3ad protocol support and guarantee that packets from a single TCP connection always go through the same link in a single direction. Configuring a link aggregation This - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 9
Setting up a host for NFS storage Note For information on performing these tasks refer to the Unisphere online help.

You can find this export path in the VNXe configuration report for the file system with the share. To - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 11
CHAPTER 2 Migrating NFS Data to the VNXe This chapter contains the following topics. l Migration environment and limitations 12 l Migrating data...12 Migrating NFS Data to the VNXe 11 - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 12
. If the NFS configuration that you want to migrate has any of the following, contact your VNXe service provider: l More shares than you want to migrate. l Permissions that you do not want to manually reassign to the VNXe shares. l Any share that you want to divide between VNXe shares. l Any share - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 13
a tool This topic describes migrating NFS data with an application-specific tool. You can migrate data by using an application-specific tool or by manually copy the data one share at a time. Procedure 1. Locate the NFS data migration procedure in the documentation for the application. 2. Use the - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 14

CHAPTER 3 Using FLR with VNXe This chapter contains the following topics. l FLR terminology and concepts 16 l Managing files with FLR 18 Using FLR with VNXe 15 - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 16
terminology and describes concepts that are important in understanding how file-level retention (FLR) works for file system storage. The VNXe NAS server supports file-level retention (FLR) for file system storage. FLR allows you to set file-based permissions on a file system to limit write access - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 17
between the LOCKED and APPEND-ONLY states. Since APPEND-ONLY files do not support the non-sequential addition of data, you should use the APPEND-ONLY state deletion of files in an EXPIRED state. You must delete EXPIRED files manually. If necessary, you can revert a file from the EXPIRED state back - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 18
not detect a virus in a locked file. The CAVA documentation on the EMC Online Support website (http://www.emc.com/vnxesupport) provides information about CAVA. l Although file-level retention supports all backup functionality, the FLR attribute is not preserved in a Network Data Management Protocol - Dell VNXe2 | Configuring Hosts to Access NFS File Systems - Page 19
