Navigator 2 at a glance
Hitachi Data Systems Navigator 2 empowers you to take advantage of the 
full power of your Hitachi storage systems. Using Navigator 2, you can 
configure and manage your storage assets from a local host and from a 
remote host across an Intranet or TCP/IP network to ensure maximum data 
reliability, network up-time, and system serviceability. Figure 1-1 details 
the task flow associated with the Navigator 2 Management Console.
Figure 1-1:  Navigator 2 Task Flow
Figure 1-1 shows Navigator 2 connects directly to the front-end controller 
of the AMS 2000 family storage system. The front-end controller 
communicates to the back-end controller of the storage system, which in 
turn, communicates with the Storage Area Network (SAN), typically a Fibre 
Channel switch. Hosts, or application servers, typically contact the SAN to 
retrieve data from the storage system for use in applications, commonly 
databases and data processing programs. 
The role that the Navigator 2 management console plays is to provide views 
of feature settings on the storage system in addition to enabling you to 
configure and manage those features. The following section provides more 
detail about what features Navigator 2 provides to optimize your experience 
with the AMS 2000 storage system.
Key features
Navigator 2 provides the following features:
• Point-and-click graphical interface with initial set-up wizards that 
simplifies configuration, management, and visualization of Hitachi 
storage systems.
• An immediate view of available storage and current usage.
• Efficient deployment of storage resources to meet business and 
application needs, optimize storage productivity, and reduce the time 
required to configure storage systems and balance I/O workloads.

Understanding Navigator 2 key terms
Before you install the Navigator 2 software, it is important to understand a 
few key terms associated with Navigator 2. Table 2-1 defines a few key 
terms associated with Navigator 2.
Table 2-1:  Understanding Navigator 2 Key Terms
TermExplanation
Host group A group that virtualizes access to the same port by multiple 
hosts since host settings for a LUN are not made at the physical 
port level but at a virtual port level.
Profile A set of attributes that are used to create a storage pool. The 
system has a predefined set of storage profiles. You can choose 
a profile suitable for the application that is using the storage, or 
you can create a custom profile.
Pool A collection of volumes with the same configuration. A storage 
pool is associated with a storage profile, which defines the 
storage properties and performance characteristics of a volume.
Snapshot A point-in-time copy of a primary volume. The snapshot can be 
mounted by an application and used for backup, application 
testing, or data mining without requiring you to take the 
primary volume offline.
Storage domain A logical entity used to partition storage.
Volume A container into which applications, databases, and file systems 
store data. Volumes are created from virtual disks, based on the 
characteristics of a storage pool. You map a volume to a host or 
host group.
RAID Redundant Array of Independent Disks (RAID) — A disk array in 
which part of the physical storage capacity is used to store 
redundant information about user data stored on the remainder 
of the storage capacity. The redundant information enables 
regeneration.
Parity  Disk A RAID-3 disk that provides redundancy. RAID-3 distributes the 
data in stripes across all but one of the disks in the array. It then 
writes the parity in the corresponding stripe on the remaining 
disk. This disk is the parity disk.
LUN Logical unit number (LUN) — An address for an individual disk 
drive, and by extension, the disk device itself. Used in the SCSI 
protocol as a way to differentiate individual disk drives within a 
common SCSI target device, like a disk array. LUNs are normal.
iSCSI Internet-Small Computer Systems Interface (iSCSI) — A TCP/IP 
protocol for carrying SCSI commands over IP networks.
iSCSI  Target A system component that receives an iSCSI I/O command. The 
command is sent to the iSCSI bus address of the target device 
or controller.
iSCSI Initiator The component that transmits an iSCSI I/O command to the 
iSCSI bus address of the target device or controller.

Quick-start checklist
Table 2-2 describes the steps for installing Navigator 2. For more 
information about a step, refer to the section in the See column. Make 
copies of the checklist for each installation performed and check each step 
after you perform it. Keep the blank checklist in this guide for future use. 
Navigator 2 operating environment
You install Navigator 2 on a management platform (either a PC, a Linux 
workstation, or a laptop) that acts as a console for managing your AMS 
2000 Family storage system. This PC management console connects to the 
management ports on the AMS 2000 Family storage system controllers, and 
uses Navigator 2 to manage your storage assets and resources. The 
management console can connect directly to the management ports on the 
AMS 2000 Family storage system or via a network hub or switch.
Before installing Navigator 2 on the management console, confirm that the 
console meets the requirements in the following sections. For an optimum 
Navigator 2 experience, the management console should be a new or 
dedicated PC.
