1–2Introduction Hitachi Storage Navigator Modular 2 User’s Guide 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.

Preinstallation Information2–1 Hitachi Storage Navigator Modular 2 User’s Guide 2 Preinstallation Information This chapter provides information you should review before installing Navigator 2. This chapter begins with the definitions for key terms associated with Navigator 2. The topics covered in this chapter are: ˆUnderstanding Navigator 2 key terms ˆQuick-start checklist ˆNavigator 2 operating environment ˆCollecting user-supplied items ˆInstalling Java runtime ˆFirewall considerations ˆAnti-virus software considerations ˆObtaining license keys ˆReviewing technical guidelines
2–2Preinstallation Information Hitachi Storage Navigator Modular 2 User’s Guide 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.
Preinstallation Information2–3 Hitachi Storage Navigator Modular 2 User’s Guide 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. Table 2-2: Navigator 2 Installation Checklist StepDescriptionSee Completed 1.
