Page 11

HBA
Connects the cluster node's PCI bus to the storage system.
Storage system
Provides external storage for the host systems (cluster nodes and stand-alone systems). Supported
storage systems include tape libraries, DAEs, and SPEs.
SAN storage
management software
Provides centralized control of the SAN for easier management. These software management tools
include:
Navisphere Agent
Navisphere Manager
EMC PowerPath
Access Logix (optional)
MirrorView (optional)
SnapView (optional)
Backup software (optional)
SAN Copy (optional)
See "
" for a description of these software management tools.
Fibre Channel switch
(optional)
Provides a communications link between the servers, storage systems, and tape libraries.
Fabric (optional)
One or more switches, which may be connected together using interswitched links.
Storage Management Software
NAS clusters require additional software components to manage the communications between the cluster nodes and the
storage systems in a SAN environment.
provides a list of Navisphere and Dell OpenManage™ software packages that are used in NAS cluster configurations.
See "
" for the storage management software required for your particular cluster configuration.

Function
EMC
PowerPath
Detects and re-establishes a failed connection to a processor enclosure caused by a communication failure,
such as a failed storage processor, SP port, link control card (LCC), HBA, switch, or fiber optic cable. Without
human intervention, PowerPath can automatically reroute the I/O through an alternate path when a failure
occurs to provide connectivity for running applications.
Additional features include:
Dynamic load balancing
Multiple path detection
Navisphere
Manager
Provides centralized storage management and configuration from a single management console. Using a GUI,
Navisphere Manager allows you to configure and manage the disks and components in one or more shared
storage systems.
Additional features include:
Creating, binding, and unbinding LUNs
Changing configuration settings
Monitoring storage systems
Navisphere Manager is installed on the Dell | EMC storage systems or a host system that has network access
to the storage system.
Navisphere
Agent
Provides an interface between the host systems and the Dell | EMC storage system, allowing Navisphere
Manager to send and receive information to and from the storage system connected to a host system.
Access
Logix
(optional)
Allows multiple cluster nodes and servers to share a Fibre Channel shared storage system. Access Logix
restricts server access to specific volumes on a shared Dell | EMC storage system and protects your data from
unauthorized access.
