Installing And Configuring The Shared Storage System; Access Control - Dell CX4 Series User Manual

Installing and Configuring the Shared Storage
System
See "Cluster Hardware Requirements" on page 8 for a list of supported
Dell/EMC storage systems.
To install and configure the Dell/EMC storage system in your cluster:
1 Update the core software on your storage system and enable Access
Control (optional) and install any additional software options, including
EMC SnapView™, EMC MirrorView™, and SAN Copy™. See your EMC
®
Navisphere
2 Install the EMC Navisphere Agent and EMC PowerPath software on each
cluster node.
See your Navisphere documentation for more information.
3 Update the storage system configuration settings using Navisphere
Manager.
See "Enabling Access Control and Creating Storage Groups Using
Navisphere" on page 49 for more information.
The following subsections provide an overview of the storage management
software and procedures for connecting the host systems to the storage
systems.

Access Control

Fibre Channel topologies allow multiple clusters and stand-alone systems to
share a single storage system. However, if you cannot control access to the
shared storage system, you can corrupt your data. To share your Dell/EMC
storage system with multiple heterogeneous host systems and restrict access
to the shared storage system, you need to enable Access Control.
Enabling Access Control prevents all host systems from accessing any data on
the storage system until they are given explicit access to a LUN through a
storage group. By enabling Access Control, you can prevent the host systems
from taking ownership of all LUNs on the storage system and prevent
unauthorized access to sensitive information.
