8 Getting started

Prerequisites Before starting the configuration process, complete the following tasks:

Obtain the WWN of the lowest numbered Front End Adapter (FA) in the configuration from the Dell EMC customer support engineer. This WWN has, by default, the ACLX device and needs to be part of the Fibre Channel (FC) zone along with the control host in order to discover the storage devices.

Install Solutions Enabler and Unisphere for PowerMax. The software and documentation for these applications is available on Dell EMC Online Support (https://support.emc.com).

Verify that your Dell EMC support representative has configured the VMAX and PowerMax systems to call home with EMS Secure Remote Services (ESRS).

Gather and record configuration information using the Setup worksheets, as described in Configuration information.

Getting started 9

Components used in a system with eNAS The following terminology is used throughout this document:

Management Module Control Station (MMCS): Used by Dell EMC Customer Support to configure eNAS, if necessary. Network Address Translation (NAT) Gateway: Used to configure the external IP address of the Control Station. Control Station (CS): Provides management functions to the file-side components referred to as Data Movers. Data Mover (DM): Clients communicate with a Data Mover using either/both NFS and CIFS/SMB protocols. Clients are

physically connected to the Data Mover through I/O modules on the storage array that are assigned to the Data Mover. The Data Mover accesses the client data by way of an internal interface to the storage array on which the Data Mover resides.

10 Getting started

Configuration information Before starting the configuration process, it is recommended that you complete the following worksheets. Because you will use this information later when you run the Setup Wizard for File, the worksheets are organized by wizard page:

24 eNAS management

eNAS File Auto Recovery Introduced in HYPERMAX OS 5977.691.684, File Auto Recovery (FAR) allows you to manually failover or move a virtual Data Mover (VDM) from a source eNAS system to a destination eNAS system. The failover or move leverages block-level Symmetrix Remote Data Facility (SRDF) synchronous replication, so it invokes zero data loss in the event of an unplanned operation. This feature consolidates VDMs, file systems, file system checkpoint schedules, CIFS servers, networking, and VDM configurations into their own separate pools. This feature works for a recovery where the source is unavailable. For recovery support in the event of an unplanned failover, an option is provided to recover and clean up the source system and make it ready as a future destination.

The manually initiated failover and reverse operations can be performed using Dell EMC File Auto Recovery Manager (FARM). FARM allows you to automatically failover a selected sync-replicated VDM on a source eNAS system to a destination eNAS system. FARM also allows you to monitor sync-replicated VDMs and to trigger automatic failover based on Data Mover, File System, or IP network unavailability that would cause the NAS client to lose access to data.

NOTE: For information on FAR and FARM, refer to the Dell EMC PowerMax Embedded NAS File Auto Recovery with

SRDF/S document available on Dell EMC Online Support (https://support.emc.com).
