Introduction 11
Each storage system in the cluster is centrally managed by one host system
(also called a management station) running EMC Navisphere
®
Manager—a
centralized storage management application used to configure Dell/EMC
storage systems. Using a graphical user interface (GUI), you can select a
specific view of your storage arrays, as shown in Table 1-4.
You can use Navisphere Manager to perform tasks such as creating RAID
arrays, binding LUNs, and downloading firmware. Optional software for the
shared storage systems include:
• EMC MirrorView™
— Provides synchronous or asynchronous mirroring
between two storage systems.
• EMC SnapView™
— Captures point-in-time images of a LUN for backups
or testing without affecting the contents of the source LUN.
• EMC SAN Copy™ — Moves data between Dell/EMC storage systems
without using host CPU cycles or local area network (LAN) bandwidth.
For more information about Navisphere Manager, MirrorView, SnapView, and
SAN Copy, see "Installing and Configuring the Shared Storage System" on
page 45.
