The following subsections provide an overview of the storage management software and procedures for connecting the host systems to the
storage systems.
Access Logix
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 can install and configure the Access Logix software.
Access Logix is an optional software component that restricts LUN access to specific host systems. Using Access Logix software, you can:
Connect multiple cluster nodes and stand-alone systems to a storage system.
Create storage groups to simplify LUN management.
Restrict LUN access to preassigned storage groups for data security.
Access Logix is installed on each storage system in the cluster. Navisphere Manager is installed on one or more storage systems, or one or
more hosts attached to the storage system(s).
The storage systems are managed through a management station—a local or remote system that communicates with Navisphere Manager
and connects to the storage system through an IP address. Using Navisphere Manager, you can secure your storage data by partitioning your
storage system arrays into LUNs, assign the LUNs to one or more storage groups, and then restrict access to the LUNs by assigning the
storage groups to the appropriate host systems.
Access Logix is required when the storage system is connected to two or more clusters, two or more nonclustered systems, or a combination
of both clustered and nonclustered systems. Access Logix is not required for stand-alone systems or single cluster configurations. Access Logix
is also required as a prerequisite to using SnapView, MirrorView or SAN Copy. Access Logix is installed by updating the core software
(firmware) on your storage system.
Table 2-3 provides a list of cluster and host system configurations and their Access Logix requirement.

Navisphere Agent
Navisphere Agent is installed on the host system and performs the following tasks:
Registers each host with the storage system
Communicates configuration information from the host to the storage system
